It is now part of codeaf, copied from swe-pro-go at 6103488 (local tag `codeaf-absorb`), and it runs only through codeaf: every model call it makes goes to a model API codeaf serves that one run. No key reaches it or any command its model runs. Each call is priced once into the conversation, the task and the spending ledger, and its ledger row names the conversation and the task, so `/cost`'s `tasks` line and the spend place show what a run cost. A call cut short by a stop or the ceiling is priced by its receipt, and the run is not over until that receipt is in (at most 70 seconds from when it was owed). The dollar ceiling refuses the call that would cross it (`the run's dollar ceiling of $… is reached ($… spent), so codeaf made no call`), and a run handed an already-spent ceiling makes no call at all. On a service that reports no prices (a local proxy, a sign-in) the dollar ceiling cannot hold; the manual says so and names `--max-hours` as the bound there. A model the person's services cannot serve is answered on the run's own work model, and the page names the model that answered." + - "A program's task page was a step list with no dollars until the run landed, and its stage was drawn nowhere. senior-dev's task opens inside the conversation's own tab, as any task does, from its row, its card, a task link, the task strip, the home panel or the sessions place; `esc`, the conversation's tab and the `home` tab leave it, and the program has no tab of its own. It shows the actions senior-dev takes, each under the step of its own process it served — `BRIEF`, `SETUP`, `SPEC`, `EXPLORE`, `PIN`, `CHECKLIST`, `IMPLEMENT`, `SUBMIT`, `VERIFY`, `FINISH` — with how each came out (`passes`, `fails · exit 1`, `4 files · 5 of 5 ticked`), the build and test commands it runs itself after the hand-in, `compacted its memory`, `switched to ` with the router's reason, its nudges and last turn drawn quieter, and `◐ thinking · 12s` while a model call is out; model names appear nowhere else. `ctrl+y` turns the page to the raw calls to its model and back. A line pinned over it says the step, the spend against the ceiling, the calls and the time, and the rail row says the step (`explore`, `verify`) and the spend. senior-dev reports this through optional fields on its protocol records (a step's `tool`, `step` and `exit`; a stage's `data`; stages `compaction`, `model-switch` and `verification · running`), and codeaf keeps them in the task's `delegate-actions.jsonl`; its algorithm is unchanged. The box sends nothing: `senior-dev reads no messages — say it to main`." + - "A senior-dev run's time was read off different clocks on different surfaces and was recorded nowhere: the page counted from before the copy was made to whenever the store happened to end, the rail from when the window first saw the run. It is now one span everywhere — from the hand-off to the moment senior-dev's own process ended, rounded to the second — on the page, the rail, the room, the landed card, the note the chat is handed (`done · ran 22m 51s · …`), the chat's `tasks` tool and the project's task list. The instants are kept in the task's `delegate-program.json`, and a reopened conversation still shows them." + - "The chat's `tasks` tool could not see a senior-dev run (`No task \"3\" in this project`), and nothing outside its own conversation could. It now reads the run, says how long it took, and every run takes a row in the project's task list, so the `@` list, other conversations and other windows see it. Another window that opens the run's row on its tasks place (`enter read it as it runs`) gets the same actions page, read-only, with `ctrl+y` for the raw calls and no stop, where it used to get the `[senior-dev]` badge over an empty page; a window reading another conversation may now read that task's stored page (and none of its verbs) on its connection. And that row was never drawn on an ordinary launch: the tasks place read the other conversations' presence only from an in-process agent, so a window on the engine (bare `codeaf`) showed another conversation's running work as `enter go inside it` and could never reach `enter read it as it runs` for any task. The engine launch now reads that presence off this machine's disk, so the row says `another window` and opens the reading page." + - "A second hand-off in a conversation whose earlier run had been left open ran inside that run's records: the second senior-dev was handed the first one's brief, and its calls, ceiling, stop and end time were written into the first task's page. Every hand-off now has its own store, record folder and brief. A run codeaf closed or crashed under used to read `running` for ever with its clock climbing; it now reads `incomplete` with `codeaf closed while senior-dev was running`, its time stopped where it was last seen working, and nothing waiting on the person. Closing a hosted conversation's window only detaches, as before." + - "Reopening a conversation after codeaf had closed under a run could set its whole task list aside as corrupt (`run row … is in state \"interrupted\"`), losing every task in it.

A program's folder is now its proposal's `ground`, or the conversation's folder when it names none (the repository's root inside one), and nothing else is read for it; a `ground` that does not exist yet is made when its parent does; the card says `where: , on a branch of its own` (or the folder), and the receipt the model is handed names it. A program is never handed the home folder or one above it: the hand-off is refused with `senior-dev works in one project's folder, and is your home folder; say which folder the work is in, as ground`, and `/senior-dev` typed there is refused the same way. On a folder with no git history, a folder or file senior-dev may not read is skipped instead of ending the run; it needs no Full Disk Access." + - "senior-dev handed a folder with no git history ended at once with `workspace is not a git repository`, from the chat and from a shell. senior-dev now uses git only if it is there: a plain folder, a repository with no commit, a `.git` with no `HEAD` or a machine with no git runs on its snapshot recorder, as `--in-place` would, with or without the flag, so the chat never meets an ending it has no flag to fix. codeaf still starts it with `--in-place` under a repository rooted at the home folder or above, where git is there and must not be written to: it works in the folder itself and commits nothing. Wherever it works, its notes (`.senior-dev/`, the whole model conversation among them) are moved into the task's record folder when it ends, unless they were there before it started." + - "senior-dev ran in a copy of the person's repository and its work was left as one squashed `task:` commit on a branch nothing merged. It now works in the person's folder itself: in a repository codeaf records the branch they are on, switches the checkout to a new branch `task/-<id>` (the person's own branch never moves), and senior-dev works there; when the run ends — done, not finished, or stopped — what it left uncommitted is committed onto that branch and the branch is left checked out, so the work is in the person's folder (`its work is on the branch <branch> in <folder>, N files, and that branch is checked out there; your branch main is as it was: `git -C '<folder>' switch main` goes back to it, and `git -C '<folder>' merge <branch>` from there brings the work in`). A run that changed nothing switches back and deletes its branch (`it changed nothing, so <folder> is back on your branch <b> and its branch <task> was deleted`). A checkout with changes not committed, or in the middle of a merge or rebase, is refused before its card: `<folder> has changes that are not committed (a.go, b.go and 2 more); commit or stash them, then ask again`. One run works in a folder at a time, from any conversation, window or shell, and a folder inside or around a busy one is busy too. While it works, nothing else of codeaf's writes there: the chat's file tools refuse a path inside the folder, and a task grounded on it is refused (`<folder> is busy: senior-dev, task 1 (<title>), is working in it, and nothing else of codeaf's works there until that run has ended; wait for it, or stop it, then ask again`); the shell is not fenced, and the person's own edits there join its work. A run whose process went away (codeaf closed, a crash, a killed shell run) is settled without touching git: its work stays on its branch as it left it, and the ending says how many files are not committed. codeaf reads the person's branch again before it says it is as it was, and switches branches with the repository's hooks off. The copy, the rewriting of folder paths in the brief, the squash and the landing are gone." + - "A program that ended without finishing drew `a fault: ran and did not finish`. The row now carries the program's own sentence (`senior-dev did not finish: submitted a change that the project's own build or tests do not pass`), is not drawn as a fault (new ending `program`), keeps that ending and its branch across a reopen, and the conversation is told the program's account; a program crash is still a fault." + - "senior-dev routed on a built-in list of six open models whatever the person's crew said. A run a conversation starts now hands it the crew's worker (`--high`) and low (`--low`) models; it skips a crew model its catalog cannot size and uses its own list only when none is left (`--crew`). The mastermind is not passed, because senior-dev has no call that would use it." + - "A model the person asked for was shown on the card and dropped: senior-dev was handed the crew's working seat whatever the proposal named. The models a proposal names (one, or several separated by commas) are now senior-dev's working pool (`--asked --high …`), named on the card and in the receipt; a model none of the connected services can serve is refused before the card, by name, where it used to be answered on the crew's seat call after call; a model spelled with a connected service's prefix (`mybox/qwen3`) is taken as written; and one senior-dev's catalog cannot size ends the run before its first call, naming it, where a crew seat it cannot size is dropped for its own list. A proposal naming no model is handed the crew, as before." + - "codeaf reached for senior-dev only when its model read a paragraph calling it for \"one large code change worth an hour\". The paragraph now says work a program is for goes to it whole, rather than to the conversation or its own worker, and senior-dev's guide claims complex, multi-part coding work in a real project: an issue in a mature codebase whose cause spans files, a feature with its tests, a rewrite across a package, a migration. A proposal that leaves out a program the person named (by name or as `/name`, in the message or a correction typed into the same turn) is turned back once — `the person named senior-dev: if they want it to do this work, propose this again with `via: \"senior-dev\"`; if they asked for it not to be used, or did not mean the program, propose it again unchanged` — every such proposal of that reply is turned back, and one the model makes after reading it passes. An ask for a program lifts the one-command floor (`fix this file with senior-dev` goes to senior-dev); a passing mention does not; a commit, undo or revert stays in the conversation whatever `via` says. The approval card and its countdown are unchanged." + - "Nothing distinguished a program's task from codeaf's own: the rail row, the card and the page drew them alike, and the card did not say where the work was going. A program's tasks now wear its name as a badge — `[senior-dev]`, bold in the accent colour, after the title — on the side list (`[sd]` on the narrow one, the `#id` going first and the title cut last), the card (`wants to start a [senior-dev] task: <title>`), the task's page, the strip, the `@` list, the tasks place and home; the chat's `tasks` tool says `via senior-dev`. The badge is made from the program's name, so a program added later wears its own. An ordinary task wears none. The card's `from your folder as it stands — unsaved edits included` line is not on a program's card." + - "senior-dev's ending went nowhere codeaf acted on: it was a sentence on a row, read by the chat only if the person asked something next. Now every run's ending wakes the conversation with how it came out (passed its own check, unchecked, fails, stopped on a limit, broke) and what to do about it, under a playbook page of its own: the chat checks the work, fixes a small gap on the branch, or hands the work back to senior-dev with a sharper brief — at most twice on its own (a third is refused: `senior-dev has been sent back to this work 2 times already, the most codeaf does on its own: tell the person where the work stands and let them decide`), and never after a dollar or time limit without the person's word. The landed card says `ended` and `senior-dev's ending went to the chat` instead of the program's status." + - "senior-dev's page named its task three times — the trail's crumb (the conversation's name, which a conversation named after its work spells the same), the bold title, and `Reading: <title>` over the box — and opened on a clipped brief. The head is now the title row alone, with its badge, a `▸ brief` dropdown and the pinned facts; the dropdown (or `ctrl+o`) draws the whole brief in grey between the head's rules.

It shows on the rail with a live step. `stop` works. +5. When it ends, the landing wakes a turn, as every task does today. That + turn reads senior-dev's terminal record and the landing note, and answers. + +The model never watches the stream. You watch the rail. + +**Rows are generated.** A manifest at `~/.codeaf/delegates/<name>.json` whose +binary is on PATH adds one row `/<name> <brief>` to the live command list, so +`/help` and the picker show it beside `/task`. No senior-dev on the machine means +no `/senior-dev` row.

Nothing above the factory changes. + +**The floor.** With no change at all, the model can run `senior-dev run …` +through the `bash` tool in the background.

Optional `data` keys the landing note reads when present: +`reason`, `claim` (what the program's model said), `observed` (what the +program itself saw), `deliverable` (the answer text, for `"lands": "text"`). + +**What this costs each program:** + +- **senior-dev** emits all four in exactly this shape as of `5793499`. Its + `step` is one per tool call reaching `completed` or `error`, never twice + for a republished part; `command` is `tool: argument`, the argument capped + at 200 bytes; `observation` is the output or the error string, capped at + 2048 bytes on a rune boundary. Nothing to adapt. +- **pr-af** needs a one-shot mode that prints these four records and exits: + `stage` per review phase, `spend` per model call, `terminal` with the + findings as `data.deliverable`, and `"lands": "text"` in its manifest. + +**Never sum `cost` off senior-dev's `message.updated`.** An assistant message is +written more than once, so a naive sum double-counts. The `spend` record +exists for exactly this reason. + +senior-dev keeps the model's claim and its own observation as separate fields. +The landing note keeps them separate too: *senior-dev says it submitted; its +verification failed 2 of 5 commands* is two sentences. + +### Two kinds of landing + +| `lands` | working copy | when the program ends | +| --- | --- | --- | +| `tree` (senior-dev) | cut per run, passed as `{{workspace}}` | squash, merge home, landing card | +| `text` (pr-af) | none; `{{workspace}}` is the person's folder, read-only by contract | `data.deliverable` is folded into the conversation the way a quick task's answer is, and the woken turn reads it | + +### Money + +1. senior-dev spends the person's key outside codeaf's provider ledger. +2. The reader hands every rising `spend` figure to the supervisor's bank. +3. At the ceiling the supervisor cancels the context, which sends SIGTERM, + which lets senior-dev write its terminal record. +4. The conversation total, `/cost` and the status line move through + `foldSpend`, as for any run. +5. The on-disk usage ledger does **not** get senior-dev's calls, because they + did not go through a codeaf lane. The spending page says `via senior-dev`. + +The ceiling passed on the command line is what is left of the smaller of the +conversation's limits (`runCostLeft`, #1281), so senior-dev cuts itself first. + +### Stopping + +`stop` on the row is `session.Cancel` with a new kind, `delegate`, listed in +`stoplaw_test.go` with its proving test. The worker terminates the process +group, waits the job grace, then kills. A terminal record inside the grace is +read and folded. Without one the row reads `stopped` with the last stage seen. + +### Landing a `tree` delegate + +*As built on 2026-09-21 and deleted on 2026-09-24: since then senior-dev works in +the person's folder on a branch of its own, its `wip(edit)` commits stay on that +branch, what it left uncommitted is committed there when it ends, and the branch +is left checked out rather than merged. `refs/senior-dev/*` are written into the +person's repository and overwritten by the next run.* + +1. senior-dev works in the run's own copy, passed as `--dir`. +2. senior-dev commits every edit as it goes: `wip(edit): <path>`, dozens per run. + These stay on inside the copy, because senior-dev's crash recovery and its + restore-after-ship read them. +3. At landing codeaf **squashes** everything past the cut point into one + commit. Subject: the task's title. Body: two sentences from the terminal + record, what the model claimed and what senior-dev observed. +4. That one commit merges home the way every task lands. +5. `.senior-dev/` is git-excluded in the copy and never lands. `refs/senior-dev/*` + die with the copy. + +## The manual law + +Delegates are added at a person's discretion, so `/<name>` rows cannot be a +build-time list, and a page compiled into every binary cannot explain them. +The law stays: every command the chat offers is explained in the corpus. Where +it is enforced moves. + +1. **The static table keeps its static gate.** `internal/tui3`'s `commands` + and its test are unchanged. Delegate rows are appended to the live list at + launch and never enter the Go literal. +2. **Each delegate ships `manual.md`** beside its manifest, following the same + rules as `internal/manual/chat/` pages. At launch the chat's corpus is the + packed corpus plus an **overlay** of installed delegate pages. `manual.Corpus` + gains one constructor that layers pages over another corpus. The `manual` + tool then answers "what does /senior-dev do" from senior-dev's own page. +3. **The check runs at load.** A page that does not mention `/<name>` refuses + the manifest. `/delegate` shows why: `senior-dev: its manual page does not say + /senior-dev — not added`. +4. **One built-in page explains the family.** *Delegates — programs codeaf can + hand a task to* mentions `/delegate` and answers "what is a delegate", "how + do I add one", "why is there no /senior-dev here". It never names a delegate + the build cannot promise exists. + +## What senior-dev changed for this + +Landed 2026-09-21 and 2026-09-22 on `zeropoint95/improvements`, PR #30. + +1. **Control plane optional** (`f3b9716`). Reachable: mirrored as before. + Unreachable: one stderr line, and the run proceeds. The `run-contract` + record carries `"control_plane": {"enabled": false, "url": "<probed url>"}`. + `senior-dev serve` still requires a plane. The manifest sets no `SENIOR_DEV_CP_*` + variable. +2. **Live spend record** (`5793499`). `{"type":"spend","cost_usd":0.0213,"ts":…}`, + top-level, one per completed assistant message, cumulative, compaction + included. Emitted even at zero. Not projected onto the control plane. +3. **Step record** (`5793499`). `{"type":"step","command":"bash: go test ./...","observation":"…","ts":…}`, + one per finished tool call. stdout only, not in the stderr trace. +4. **No question road**, by decision.

In a repository with a commit whose root is below the home +folder, codeaf writes the person's branch down, refuses a checkout with changes +that are not committed or a merge half done, and cuts the program's own branch +with `git switch -c task/<title>-<id>`; the program works there in its own git +mode. Anything else — no history, no commit, or a repository at the home folder — +is worked in as it is, and codeaf puts the program's own `PlainFolder` flags on +its line (senior-dev's is `--in-place`), because the program's own reading climbs +to any repository around the folder. senior-dev reads its folder too, and uses +git only where there is a work tree with a commit, so the flag is needed only +where git IS there and must not be used (the home folder's repository) — a +plain folder never ends it, whatever its line says. codeaf never learns a program's flag by +name, and a flag the default command does not take fails `Validate`, so the +build's own test catches it. One folder takes one program run at a time, held by +a file lock that dies with its process. + +**The brief is handed over as written.** There is no copy for a path in it to be +rewritten into. + +**A tree program's work stays on its branch, checked out.** When the run ends, +however it ends, codeaf commits what the program left uncommitted onto its branch +(the task's title, the ending as the body), moves the program's notes out of the +folder, and leaves the branch checked out; the person's branch never moves and +nothing is merged into it. The page says `its work is on the branch <branch> in +<folder>, N files, and that branch is checked out there; your branch <yours> is as +it was: …` with the commands that go back and bring the work in. A run that +changed nothing switches back and deletes its empty branch; a HEAD the program's +shell moved off its branch is left where it is and said. + +**The crew rides the line.** A run a conversation starts carries its crew +(`delegate.Crew`: brain, hands, light — the mastermind, worker and low tiers, +effort taken off) in the program's own flags (`Delegate.CrewFlags`); a program +with none picks its own models. senior-dev's are `--crew --high <hands> +--frontier <brain> --low <light>`, and `--crew` makes it drop a model its +catalog cannot size, and route on its own list if the working seat is left +empty, rather than fail the run. `Validate` parses the flags with the default +command, as it does the plain-folder ones. + +**A program's own ending names the row.** A terminal that is not `pass` +reaches the session typed (`run.ProgramEndedError` → `session.ProgramEnding`): +`fail` and `budget` end the row on `TaskEndingProgram`, whose reason is the +program's sentence (`senior-dev did not finish: …`) and which is not a fault; +`crashed` is `TaskEndingError`, the fault it is. + +- **From the chat,** the engine's run (`internal/run`'s `DelegateWorker`) starts + that line in the folder the proposal names (`propose_task`'s `ground`) or else + the conversation's own. +- **From a shell,** `codeaf <name> <brief>` becomes the host: it serves the model + API itself, readies its folder the same way, and starts the same child. + +The two are told apart by the environment. A child of a host has +`CODEAF_MODEL_API` and `CODEAF_MODEL_TOKEN`; a person's shell has neither. + +The child's environment is the parent's with every provider key and model +redirection codeaf knows of removed (`delegate.ChildEnv`). The program passes its +environment on to every command its model runs, so a key left there would be one +any model-written shell line could print. + +## 3. The model API — the only road to a model + +For each run codeaf serves an OpenAI-style chat-completions API at +`CODEAF_MODEL_API` (a base URL), opened by the bearer token in +`CODEAF_MODEL_TOKEN` and by nothing else. It lives in `internal/provider`, the +one package codeaf's funnel law lets spell a model route. Every call: + +1. is refused before it is made when the run's dollar ceiling is reached, with + HTTP 402 (a status senior-dev does not retry). A run a refusal ended is + reported as `<name> reached the run's dollar ceiling of $X: …`, whatever + status the program itself wrote, and ends on the run's cost limit; +2. goes through codeaf's own model funnel, with its router, retries, caching and + billing, on the model the program asked for when one of the person's + services can serve it, and otherwise on the run's work seat, which the turn + names in `Served` (`modelapi.Resolve`; a call is never refused only because + the machine does not know the id); +3. is answered in the OpenRouter shape, `usage.cost` included, streamed with + keepalives while a long call is thinking, or as one body when it was not + streamed (`response_format` carried); +4. is banked to the task's spend and the spending ledger, and written to the + run's conversation log. + +The token dies with the run, so a grandchild that outlives its parent can no +longer spend. A call's thread is its `prompt_cache_key`, or its +`x-session-affinity` header when the body carries no key; reasoning effort rides +codeaf's own effort ladder. + +A shell run (`codeaf <name> …`) has no task folder, so its record — the +conversation log, the program record and the program's stderr — goes to +`~/.codeaf/v3/carried/<name>/<when>/`, one folder per run. Its child is started +with the person's own line plus `--json`, so a command other than the default +and the command's own flags survive. + +## 4. The records — stdout, one JSON object per line + +| record | when | fields | +| --- | --- | --- | +| `hello` | first | `protocol` (2), `delegate`, `stages` (the whole list, in order) | +| `stage` | on every phase change | `stage`, `status`, and optionally `data`: a JSON object of at most 1024 bytes (`delegate.StageDataCap`) | +| `step` | once per finished action | `command` (one line, 200 bytes at most), `observation` (2048 bytes at most), and optionally `tool` (the tool's name), `step` (the program's own id for the part of its process the action served), `exit` (a command's exit code, only for an action that ran one), and `added` and `removed` (the lines an action that changed a file added and removed, only when the program counted them) | +| `terminal` | last, exactly once, on every path | `status` (`pass`, `fail`, `budget-exhausted`, `crashed`), `message`, `data`: `reason`, `claim`, `observed`, `deliverable`, and anything else | + +Any other line is ignored. There is no `spend` record: the model API meters +every call as it is made, so money has one source of truth and it is not the +program's word. + +**The optional fields are additive, and they are version 2.** The version moves +only when a record changes meaning (`delegate.ProtocolVersion`); a field a +reader does not know is ignored like any other, so a reader that predates +`data`, `tool`, `step` and `exit` reads the same records without them, and a +program that sends none of them is read exactly as before. They are read +forgivingly: a `tool`, `step`, `exit`, `added` or `removed` of another JSON shape is left off and +the step kept, and `data` that is not an object, or is past the cap, is left +off and the stage kept. + +A stage's `data` is a small, curated copy of what the program already knows +about the phase — senior-dev's is an attempt, a retry count, its checklist's +counts, the hand-in's size, what its own check found, the model it moved to — +for a page to say in words; the program's whole account stays on its stderr. +senior-dev's step ids are `brief`, `explore`, `pin`, `checklist`, `implement`, +`submit` and `verify` (`internal/seniordev/app`'s `Steps`); the last is the +project's own build and tests, which senior-dev runs itself with no model after +the hand-in and when it checks the tree mid-run, each command one step. + +A `hello` carrying another protocol number means the engine outlived a rebuild +and started the new binary as its child. The run is stopped before it spends, +with the reason `codeaf was rebuilt while this conversation was open …; restart +codeaf to run <name>`. + +## 5. Stop + +SIGTERM to the process group, a 15-second grace, then SIGKILL. On SIGTERM the +program stops starting new work, writes its terminal, and exits. A body that +returns without writing a terminal gets one written for it (`delegate.RunChild`). + +A host that dies without a word — killed, or taken by a closed terminal's +hangup, which never reaches a child in a process group of its own — sends no +SIGTERM. The child looks for its parent once a second and, when the process that +started it is no longer its parent, stops exactly as a SIGTERM would stop it, and +is ended outright if it is still at work when the grace has passed +(`delegate.RunChild`'s `watchHost`). A shell run's host itself treats SIGHUP as +its first ctrl-c. + +## 6. The conversation log and the action log + +`delegate-conversation.jsonl` in the task's record folder, one `delegate.Turn` +per model call: the thread, the model asked for and the one that answered, what +the program sent that the thread's previous call had not, the reply and the tool +calls, tokens and cost, and codeaf's refusal or the model's failure. A call is +written when it starts and again when it ends, and a reader keeps the later +record, so the task page shows the call in flight. + +`delegate-actions.jsonl` beside it, one `delegate.Action` per record the program +wrote — `stage`, `step`, and its ending (`end`: the terminal's status and +message) — each stamped `at` with the moment codeaf received it, because a +program's own clock is not trusted and the page merges this log with the +conversation log, whose times are codeaf's too. The run's worker writes it and +so does a shell run, into its own record folder; it is capped as the turns are. + +**The page draws actions, not the dialogue.** A program's own vocabulary +(`Delegate.Present`, a reader told every line of the log in order) turns each +line into what a person reads under the step of the program's process it +served (`delegate.Shown`); the page merges those with what only the calls know +— a compaction, a change of the model answering, a refused or failed call — by +time, and keeps the dialogue of the raw calls one key away. The live step names +the step the program is in: the word the program's reader gives the latest +record that named one, and its stage's word before any has. + +## 7. What a program may not do + +- Ask a person anything. Nobody is at its keyboard. (Later: a tool codeaf runs + inside the model API.) +- Read stdin. +- Reach a model any way but the model API. +- Write anything on stdout that is not a record on its own line. +- For `tree`: touch files outside its workspace, or leave anything in it that is + not its work (its own state git-excluded). senior-dev enforces the first for its + file tools: `write`, `edit` and `apply_patch` refuse a path outside the + workspace, links resolved (`tool.RegistryOptions.ConfineWrites`), while reads + stay open. Its shell is not fenced; its prompt says that nothing a shell + command changes outside the workspace comes back. + +## 8. Built in now for later programs + +pr-af and sec-af, looked at on 2026-09-23, would need: plain structured calls +with `response_format`, many conversations at once (kept apart by thread), +grandchildren inheriting the API's address and token, quiet stretches of up to +30 minutes, and text landings with attachments. The first four are in v2 from +the start; attachments come with the first text program. diff --git a/internal/config/config.go b/internal/config/config.go index 9ce82f04aa..bc1484afae 100644 --- a/internal/config/config.go +++ b/internal/config/config.go @@ -360,6 +360,11 @@ func LoadKeyless() (Config, error) { return load(false) } // though NewSettings(...).Rows() does not list them. var nonSettingProfileFields = []string{ KeySetupSeen, + // The talk lane's borrow row sits beside its lane row and is read by + // [LaneBorrowAt], but it is set from the lane page and not from a settings + // row of its own.

A run starts at once in your folder, the turn goes +on, and the row appears on the rail. + +The model can choose one as well, and reaches for one by itself (see *When codeaf hands +work to a program by itself*). `propose_task` takes `via` naming the program, and the +card you answer says which program the work is going to: it asks `wants to start a +[<name>] task: <title>`, and its top line wears the program's badge. The model is told +the programs your build carries, each in the program's own words: what it is for, what its +brief must say, and what it needs of its folder. + +At a shell, `codeaf <name> <brief>` runs the same program in the folder you are in, or the +one `--dir` names. `--max-cost` and `--max-hours` set its ceilings, and `--json` prints its +records instead of readable lines. `codeaf <name> --help` lists its own commands and flags. +Its last line says what the run came to, such as `277 model calls · $2.30 · 22m 51s`: the +calls, the dollars and how long the program ran. + +## When codeaf hands work to a program by itself — will it use one without being asked, naming one is enough, it did the work itself instead + +The chat's model is told to hand the work a program is for to that program, whole, rather +than doing it itself or giving it to codeaf's own worker, even when it is one long job +with nothing to run beside it. Each program's own line says what it is for: senior-dev's +claims complex, multi-part coding work, such as fixing an issue in a mature codebase +whose cause spans files, a feature with its tests, a rewrite across a package, or a +migration. The model proposes that work with `via` naming the program, and its card goes +up like any proposal's. + +**Naming the program is enough.** Say it in your message, by name or as its command +("fix issue 412 with senior-dev", "give this to /senior-dev", "senior dev should do +this"), and the model is told to use it. If it proposes the work without the program +anyway, codeaf turns that proposal back once, along with every other proposal without +it in the same reply: +``the person named senior-dev: if they want it to do this work, propose this again with `via: "senior-dev"`; if they asked for it not to be used, or did not mean the program, propose it again unchanged``. +A proposal the model makes after reading that passes as it is, so "don't use senior-dev +for this" is kept too. The next section says what else counts. + +**What it does not do.** A reply codeaf moves to a task on its own, because it ran long or +looked like work, goes to codeaf's own worker and never to a program. A task never hands +its work to a program. `/<name> <brief>` starts the program at once, with no card. + +## Naming a program in a small ask or a correction — fix this file with senior-dev, revert what senior-dev did, I typed a correction and it forgot senior-dev + +**An ask for a program is never too small.** A one-file fix or a single read otherwise +stays in the conversation, but "fix this file with senior-dev" goes to senior-dev. For +that, your words have to ask for the program: its command (`/senior-dev`), its name +first in the message, or its name right after with, via, using, use, give, hand, to, +have, let, ask, get or want. A name in passing asks nothing: "fix senior-dev's typo in +this file" or "fix the line senior-dev changed in this file" stays here. + +**A commit, an undo or a revert stays here, whatever it names.** "revert senior-dev's +commit", "commit senior-dev's changes" or "revert this commit with senior-dev" is done in +the conversation, and a proposal for it is refused: a program works on a branch of its +own and never moves yours, so it could not do it. `/senior-dev <brief>` still starts it. + +**A correction does not undo the name.** Every message you type into one turn is read for +the program's name, not only the newest. Name senior-dev, then type "the failing test is +TestRetryUnderLoad" while it reads the code, and the name still holds for the rest of that +turn and for a turn a finished task or job wakes to answer it: a proposal without the +program is turned back as above, and "fix this file only" typed after the name still goes +to senior-dev. A correction that does not name the program earns no second turn-back. Your +next message that starts a turn of its own is read on its own. + +## Which folder a program works in — a repository I have not cloned, it edited files outside its folder, a folder with no git + +A program that edits code works in one folder itself, never a copy: the one the task +names as its `ground`, or this conversation's own folder when it names none (a typed +`/<name>` names none). Nothing else moves it — not `where`, not a path in the brief, not +where the conversation has been working — and the task's receipt names the folder. +Inside a git repository it is the repository's root. A `ground` that is not there yet is +made, empty, when the run starts, as long as the folder it would be made in is there. +Only what it changes there is part of the task. While it runs the folder is the +program's: codeaf's own file tools and tasks keep out of it (senior-dev's page says how). + +**It is never handed your home folder**, or a folder above it: that is not a project. A +conversation opened in your home folder names the project's folder (making one first when +the work is new), and a hand-off that names none is refused with `<name> works in one +project's folder, and <folder> is your home folder; say which folder the work is in, as +ground`. `/<name>` typed there is refused the same way, and says to open codeaf in the +project's folder or to ask in the chat and say which folder. + +So when the work belongs in a repository that is not on this machine (a benchmark task +that names a repository and a commit), the model clones it first, into a new folder, at +the commit the work names, and hands the program that folder, never a brief that sends +it to work in another folder. + +A folder with no git history (a plain folder, a repository with no commit yet, or a +folder in a repository whose root is your home folder) is worked in as it is, and codeaf +tells the program so on the line it starts it with (senior-dev is given `--in-place`), +from the chat and at a shell. Nothing is committed: its changes are already in the +folder when it ends. senior-dev also reads this itself: it uses git only if git is +there, so it never ends for want of a repository. + +At a shell, clone the repository yourself, then run `codeaf <name>` inside it, or name the +folder with `--dir`. + +## What it cannot do — why it did not ask me, no questions, no step cap, no review round + +**It cannot ask you anything.** Nobody is at its keyboard. Write the brief so that +everything it would stop and ask is already settled. The model is told the same thing when +it proposes one. + +**It has no step cap.** It is held to this conversation's dollar and time limits. It is +given them when it starts, and codeaf enforces them from outside as well: once the run's +spend has reached the dollar ceiling, every further model call is refused before it is +made, and the task then says `<name> reached the run's dollar ceiling of $…`. The call +that crossed the ceiling was already paid for, so a run can end a little over it. On a +service that reports no prices (a local proxy, a vendor's own API, a plan you signed in +to) no call has a price to add up, so the dollar ceiling cannot hold: a time limit +(`--max-hours`) is the bound there. + +**It has no review round.** codeaf's checker does not read its work afterwards. What the +program itself checked is reported in its result, kept apart from what its model claimed. + +**It ends with the engine holding the conversation.** Leaving a hosted conversation's +window only detaches it. If that engine stops or crashes, the conversation is closed, or a +`--no-host` codeaf quits, the run ends with `codeaf closed while <name> was running` where +it was last seen working, or `<name> had ended; codeaf closed before it could say where its +work is` at the program's exit; the next codeaf to find the run says where its work is, +as it was left, and commits nothing. Nothing carries it on; the next hand-off starts a +run of its own. + +## Why was the delegate refused — uncommitted changes, the folder is busy, it runs alone, no such program + +**It needs a clean checkout.** In a repository with changes that are not committed +(modified, staged or untracked files), or a merge, rebase or cherry-pick half done, it is +refused before anything starts, and nothing is switched or spent: `<folder> has changes +that are not committed (<files>); commit or stash them, then ask again`, or `<folder> is +in the middle of a merge; finish it or abort it, then ask again`. The model reads this +before you are shown a card. + +**One folder takes one program run at a time**, from any conversation, any window or a +shell: `<folder> is busy: <name>, task 4 (…), is working in it, and one folder takes one +program run at a time; ask again when that run has ended`.

When it ends, codeaf commits what +it left uncommitted onto that branch — the task's title, with the program's own account +of the ending as the body — and **leaves the branch checked out**, so the work is in your +folder. **Your own branch never moves**, and nothing is merged into it; if anything else +moved it during the run, the page says so instead of `as it was`. The task's page +and the conversation say ``its work is on the branch <branch> in <folder>, N files, and +that branch is checked out there; your branch <yours> is as it was: `git -C '<folder>' +switch <yours>` goes back to it, and `git -C '<folder>' merge <branch>` from there brings +the work in``. Ask the chat to merge it, or run that yourself, when you are ready. + +A run you stop keeps its work the same way.

It is built +into codeaf and runs only through it: there is nothing to install and no senior-dev of +its own to start. + +It works alone in your folder itself, on a branch of its own when the folder is a git +repository, and your own branch never moves. It writes your brief down word for word, reads +the repository, keeps a checklist of what the brief asks for, pins a command that shows +the work passes, and edits until it believes the change is done. Then it **submits**: +the tree is frozen at that moment, so nothing it does afterwards can change what it hands +back. It then runs the project's own build and tests on the frozen tree, and if anything +moved after it submitted, the tree is put back to what it submitted. + +It is for complex, multi-part coding work: fixing an issue in a mature codebase whose +cause spans files, a feature with its tests, a rewrite across a package, a migration. +codeaf hands work like that to it by itself, and uses it whenever you name it (the next +section). Its brief has to settle everything, because nobody will be asked anything. + +## Will codeaf use senior-dev by itself — when does codeaf hand work to senior-dev, how do I make codeaf use senior-dev, stop it using senior-dev + +**Yes, for the work it is for.** The chat's model is told to hand complex, multi-part +coding work to senior-dev, whole, rather than doing it in the conversation or giving it +to codeaf's own worker: fixing an issue in a mature codebase whose cause spans files, a +feature with its tests, a rewrite across a package, a migration. It proposes the task +with `via` naming senior-dev, and the card goes up like any proposal's, with its +countdown. A change you would make in a few steps it still makes itself. + +**Naming it is enough.** Say senior-dev in your message, in any spelling: "fix issue 412 +with senior-dev", "/senior-dev should take this", "senior dev". The model is told to use +it, and if it proposes the work without senior-dev anyway, codeaf turns that proposal +back once, with any others in the same reply, and tells it you named senior-dev. That +holds even for a one-file fix you ask senior-dev for, which otherwise stays in the +conversation, and through a correction you type while it works that does not name +senior-dev again. A commit, an undo or a revert stays in the conversation even when it +names senior-dev ("revert senior-dev's commit"): senior-dev works on a branch of its own +and never moves yours. + +**Saying not to is kept too.** "don't use senior-dev for this" names it, so the first +proposal is turned back the same way; the model reads that and proposes it again as it +was, and that proposal passes. + +**Typing `/senior-dev <brief>`** starts it at once, with your brief word for word and no +card. Work codeaf moves to a task on its own, because a reply ran long or looked like +work, goes to codeaf's own worker, never to senior-dev. + +## Watching senior-dev work — open its task, what it is doing step by step, how long it has run, stop it + +A senior-dev run is a task of the conversation that started it. Its row is on the side +list wearing `[senior-dev]` after its title, with the step it is in and what it has spent +so far under it, and a card in the conversation lands when it ends. Click the row or the +card, or follow a task link to it, and its task opens **inside the conversation's own +tab**: the tab strip stays on top, with the conversation's tab selected and the `home` tab beside +it. senior-dev gets no tab of its own. + +The task shows **what senior-dev is doing**, action by action, each under the step of its +process it served — the workspace it set up, what it read and ran and changed, its +hand-in, the build and tests it ran itself, and how it finished — with the call to its +model in flight as the last line, `◐ thinking` and its seconds. The next section says what +each step means. **Click an action to see the whole step** — the command or file it was +called with and what came back — and click it again to fold it. **Every change to your +files wears git's `+N,-M`** at the right of its line — the lines it added in green and the +lines it removed in red — so you can see how much each step moved the work; senior-dev's +own spec, pinned check and checklist wear none. + +The one line over it is the task's title with its `[senior-dev]` badge, a `▸ brief` +dropdown, and the step, the spend of the run's ceiling, the number of model calls and how +long the run has been going — the same time the side list and the landed card show, +counted from the moment codeaf handed the work over. **The brief is behind the dropdown**: +click `▸ brief`, or press `ctrl+o`, and the whole brief senior-dev was handed is drawn in +grey under the title; the same again hides it. While the +task is open, its row on the side list leaves its clock out rather than show a time that +stopped when you clicked; the true time is back on the row the moment you leave. + +**The raw calls are one key away.** `ctrl+y` turns the page to senior-dev's calls to its +model — what it sent, what the model answered, and which model it was — and `ctrl+y` +turns it back; the key row says `ctrl+y calls` or `ctrl+y actions`. + +`esc`, a press on the conversation's tab, or a press on the `home` tab leaves it, and the run goes +on. `x` over an empty box, `/stop`, or `Stop` on that line asks `Stop this task?` first. +Nothing typed there reaches senior-dev: the box says `senior-dev reads no messages — say +it to main`, and `enter` says the same line and keeps your words in the box. + +## What is senior-dev doing — the steps on senior-dev's page, what spec, explore, pin, checklist, implement, submit, verify mean + +The word down the left of senior-dev's page, and on its row while it runs, is the step of +its own process an action served. senior-dev has no planner, reviewer or helper agent: +one model works through the middle steps in the order it chooses, so a step's word comes +back whenever it returns to that step. + +- `setup` — it set up the folder it works in: `git`, or `no git history` for a plain + folder, whose checkpoints it keeps outside it. +- `spec` — it wrote your brief down word for word as its spec, and read it back. +- `explore` — it read, searched and ran commands before changing any file. +- `pin` — it wrote down the one command that shows the work passes. +- `checklist` — it listed what the brief asks for, and ticked it off. +- `implement` — it changed files, and everything it read or ran after its first change. +- `submit` — it handed in its work: `handed in its work · 4 files · 5 of 5 ticked`, or + `its hand-in was refused` and why. The work is frozen at that moment. +- `verify` — with no model, it ran the project's own build and tests itself, one line per + command with `passes` or `fails · exit N`, then what they came to. It also checks the + tree this way when its model stops without handing in. +- `finish` — what it did to the tree it leaves, the size of its change, and its ending. + +Lines with no word of their own are senior-dev steering its model in the step already +under way, drawn quieter: `told its model what it found, and to finish and hand in (nudge +1)`, `time is short: gave its model one last turn to finish`, a dropped call retried, a +tool call written as text corrected — and `compacted its memory` and `switched to <model>` +with its reason. + +## How do I tell a senior-dev task from a normal task — the [senior-dev] badge, [sd], what the brackets on a task mean + +A task handed to senior-dev wears its name as a badge wherever a task is named: +`[senior-dev]`, bold in the accent colour, after the task's title. A normal task — one +`/task` starts, or one the chat hands to codeaf's own worker — wears no badge. + +- **The side list** wears it after the title. When the list is too narrow for + everything, the task's number (`#7`) goes first; then the badge shortens to its + initials, `[sd]` — the narrower list a frame under 120 columns draws reads + `⠋ rewrite the… [sd] #7` — and the title is cut last. Widened with `w`, the list has + room for the whole badge and the number. +- **The card you answer** asks `wants to start a [senior-dev] task: <title>`, and the + card's top line wears the badge beside the task's name. +- **The task's own page** wears it beside the title — a page onto another + conversation's task too, with that task's own badge and never the one a task of the + same number in this conversation wears. +- **The task strip**, the row of chips that stands in for the side list under 100 + columns, wears `[sd]`. +- **The `@` list, the tasks place and home** — its list of work, a landing under + `needs you` and a line under `since you left` — wear `[senior-dev]`, or `[sd]` where + the row is short of room. The title is cut before the badge, and a `since you left` + line cuts what the work came to first: `rewrite the auth middleware [senior-dev] · it…`. +- **The chat's `tasks` tool** says `via senior-dev` on the row, so the chat can tell too. + +The brackets are always drawn, so a terminal with no colour, the row of the task you +have open, and a screen reader all still show the badge. It is not a button: a press +anywhere on the row opens the task. + +## How do I ask senior-dev for a change — writing the brief, what to put in it + +The brief is everything senior-dev knows about what you want. It is saved as +`.senior-dev/spec.md` in the folder it works in exactly as you wrote it, and it is read +back from there whenever senior-dev summarises its own history, so the words you chose +are never paraphrased away. + +Write it the way you would hand work to someone who cannot reach you: + +- the files, packages or commands involved, by name; +- what done means, and how to check it (the test to run, the output to see); +- the constraints: what must not change, and the wrong answer to avoid. + +In the chat, `/senior-dev` followed by the brief starts it as a task. At a shell, flags go +before the brief, and `--` ends them: `codeaf senior-dev run --variant high -- rename the +config loader`. Everything from the first word that is not a flag onwards is the brief, +so a flag written after the brief becomes part of it. + +## Running senior-dev on a repository you have not cloned — a benchmark task, another project + +senior-dev works in the folder it is handed and nowhere else, so it has to be handed the +repository the work belongs in. + +In the chat, ask for the work and name the repository, and the commit if the work names +one. The model clones it first, into a new folder, at that commit, and hands senior-dev +that folder. A benchmark task works this way: senior-dev works in the project's own +repository and not in the benchmark's, so the benchmark's files, its reference solution +among them, are not in its folder. + +At a shell, clone the repository yourself, then run `codeaf senior-dev` inside it or pass +the folder with `--dir`. + +A brief that names the folder it works in is fine: senior-dev reads it as written. A +brief that tells senior-dev to make a checkout of its own somewhere else does not work: +its file tools refuse to write outside its folder, and what a shell command changes out +there is not part of the task. + +## What senior-dev cannot do — it cannot ask you anything, wait on another task, be retried or carried on, no step cap, no Windows + +**It cannot ask you anything.** Nobody is at its keyboard: a question its model tries to +ask is turned down inside the program, and after three it is told questions are not +available. Put everything it would stop and ask into the brief. + +**It cannot wait on another task.** A task handed to senior-dev starts the moment it is +approved, so a proposal whose `depends_on` names work that has not finished is refused +before its card: `depends_on names task 3, which has not finished, and senior-dev starts +the moment it is approved — it cannot wait. Propose it again once task 3 has landed, or +with depends_on left out if nothing must finish first.` The chat is told when that task +lands and can propose it again then. The other way round, a task may name a senior-dev +run that ended done in its `depends_on` (the run's work is on its branch, in its folder), +but not one still going: `depends_on names task 5, a program's run that has not ended, +and a task cannot wait on one.` + +**A run is never resumed, but codeaf may send the work back.** A run that ended is not +started again: `senior-dev's run is never carried on: its work is left where it ended, and +a new hand-off starts a new run`. Its card offers no retry, and the `@` list offers no +steer on a running one, because it reads no messages. What codeaf does instead is the next +section. + +## What codeaf does when senior-dev ends — its ending, checked, sent back, retry, at most twice, ask before spending more + +**senior-dev's ending goes to the chat, not to you.** The moment a run ends, the +conversation wakes on its own with how it came out — passed its own check of the project, +nothing finished checking it, handed in work that does not pass, stopped on a limit, or +broke — and acts on it: + +- **passed**: the chat looks at what changed against what was asked, then tells you where + the work is and offers to merge its branch; +- **nothing checked it**: the chat runs the project's checks on its branch itself, then + acts on what they show; +- **does not pass, or did not finish**: the chat fixes a small gap on its branch itself, or + hands the work back to senior-dev with a brief sharpened by what failed; +- **stopped on a dollar or time limit**: the chat never sends it back on its own, because + another run spends more of your money: it says what is done and what is left, and asks; +- **broke**: the chat hands it back once if the cause looks passing (a network or model + service failure), and otherwise tells you what broke. + +**codeaf sends senior-dev back at most twice on its own** for one piece of work. A third +hand-off it tries, or one after a limit, is refused +(`senior-dev has been sent back to this work 2 times already, the most codeaf does on its +own: tell the person where the work stands and let them decide`), and you decide. A +hand-off you ask for yourself is yours, and starts the count again. Each hand-off still +shows its card, with the same countdown as any other, so you can stop one. + +**Every run on the same work stays on one branch.** A run handed a folder that the last +senior-dev run left on its branch carries on on that branch rather than cutting another: +`it works alone in <folder> itself, carrying on on its branch <branch>, where the last run +left it; your branch main does not move`. Its ending names your own branch, and a run that +adds nothing never deletes what an earlier one committed. Switch the folder to another +branch first and the next run cuts its own. + +**The card stays quiet.** senior-dev's landed card says the run `ended` (never a red +cross) and `senior-dev's ending went to the chat`; the chat's own reply is where you read +what came of the work. `ctrl+o` on the card still shows senior-dev's own words. + +**It has no step cap.** It is held to the conversation's dollar and time ceilings instead, +and codeaf enforces both from outside whatever it does. On a service that reports no +prices the dollar ceiling cannot hold, and a time limit is the only bound (see the section +on services that report no prices). + +**It reaches a model only through codeaf.** It holds no key and reads none; a +`senior-dev.json` in your folder that sets `apiKey`, `baseURL` or `providerRouting` is +refused by name, because codeaf decides which model service serves each call. + +**It writes only inside its folder.** Its file tools (`write`, `edit`, `apply_patch`) +refuse any path outside the folder it was handed, including one reached through a link, +and say so to its model; it can still read files elsewhere. Its shell is not fenced the +same way, and nothing a shell command changes outside the folder is part of the task. + +**It keeps its record in git if git is there**, on its own branch. Where there is no git +history it keeps its checkpoints outside the folder instead and commits nothing — it +reads that itself, and never ends for want of git (see the section on folders that are +not a git repository). + +**On Windows it is absent**: there is no `/senior-dev` and no `codeaf senior-dev`. Its +engine needs a Unix shell, process groups and file locks, so Windows builds leave it out +rather than carry something that fails every time. + +## Can I run senior-dev in a folder that is not a git repo — a plain folder, no git, --in-place, operation not permitted, .Trash + +Yes. **senior-dev uses git only if it is there.** A folder with no git history — a plain +folder, a repository with no first commit yet, a broken `.git`, a machine with no git — is +worked in as it is: senior-dev reads that itself when it starts, keeps its checkpoints +outside the folder and makes no commits. A folder inside a git repository whose root is +your home folder (a dotfiles repository) is worked in the same way, because codeaf starts +senior-dev with `--in-place` there: no branch is ever cut in your dotfiles. + +When it ends its changes are already in the folder. The task's page says `its work is in +<folder>, which has no git history, so nothing was committed` (or, under a repository at +your home folder, `its work is in <folder>; the git repository around it is at <repo>, +which holds your home folder, so codeaf cut no branch there and committed nothing`). + +It works in your folder itself, so leave that folder alone while it runs: once it has +submitted, anything changed there is put back to what it submitted, and a file added +there is removed. codeaf's own file tools and tasks keep out of it until then. + +**A folder or file in it that senior-dev may not read is skipped**, not a reason to stop: +it is in none of its checkpoints, and nothing of it is changed or removed. senior-dev +needs no Full Disk Access; a folder macOS keeps to itself (`operation not permitted`) is +skipped like any other. It is never started on your home folder or a folder above it +(see the programs page): to check what it changed, it reads every file in the folder, +and your home folder is not one project. + +senior-dev used to stop at once there with `workspace is not a git repository: +<folder>; run with --in-place to work in a plain folder`, which the chat could not act on. +It no longer does, whatever flags it is started with. + +## Why can't codeaf edit files while senior-dev is working — the folder is senior-dev's while it runs, a write or a task refused, bash, your own editor + +senior-dev works in your folder itself, so **the folder is senior-dev's until the run +ends**: once it has submitted, anything changed there is put back to what it submitted +and a file added there is removed, and what is left over is committed as its work. So +nothing else of codeaf's writes there meanwhile, from any conversation, window or shell: + +- the chat's `write` and `edit`, `edit_video`, and a picture, music, video or speech + saved at a path there are refused: `<file> is in <folder>, where senior-dev, task 4 + (Fix the parser), is working, so nothing was written; wait for that run to end, or stop + it, then write there`. Reading stays open. +- a task on that folder, inside it or around it — proposed, typed with `/task`, a quick + task, or one whose turn to start comes — is refused before it starts: `<folder> is + busy: senior-dev, task 4 (Fix the parser), is working in it, and nothing else of + codeaf's works there until that run has ended; wait for it, or stop it, then ask again`. +- a task already running when it started lands beside it: `its branch <branch> was kept: + senior-dev, task 4 (…), is working in it — bring it in when that run has ended`. A + `/land` of the chat's changes there is refused the same way, and waits. + +**`bash` is not fenced**: codeaf cannot know what a command writes. **Neither is your +own editor**: what you save there while it runs joins its work, or is put back. + +## Its notes — .senior-dev, its checklist, its session database, moved out when it ends + +senior-dev keeps its own records in `.senior-dev/` in the folder it works in: the brief, +its checklist, the command it pinned, its session database and its whole conversation +with its model. **They are moved out of your folder when the run ends or you stop it**, +into the task's record folder beside `delegate-conversation.jsonl` (a shell run's record +folder at a shell), and the page adds `its notes (.senior-dev/) are kept in <path>`. So +they never end up on a branch, and the next run in that folder never reads the last +one's checklist as its own. A `.senior-dev/` already in the folder when the run began is +left where it is, and never ends up on a branch either. + +## Where does senior-dev put its work — its own branch, checked out in your folder, not merged, not squashed + +In a git repository, codeaf cuts a branch of its own for the run (`task/<title>-<id>`) +in your folder and checks it out there, and senior-dev works on it. senior-dev commits +every file it writes (`wip(write): <path>`, `wip(edit): <path>`) on that branch, which is +how it keeps a record to restore from; they stay there, and nothing squashes them. + +When the run ends — finished or not, stopped, or crashed — codeaf commits whatever it +left uncommitted onto that branch, in one commit whose subject is the task's title and +whose body is senior-dev's own ending (unless codeaf itself closed first: then nothing +is committed), and **leaves the branch checked out**, so the work is in your folder +when you look. Nothing is merged into your own branch. The task's page +and the conversation both say ``its work is on the branch <branch> in <folder>, N files, +and that branch is checked out there; your branch <yours> is as it was: `git -C '<folder>' +switch <yours>` goes back to it, and `git -C '<folder>' merge <branch>` from there brings +the work in``. Merge it when you are ready, or ask the chat to. + +The ending keeps two witnesses apart: what senior-dev's model said it did +(`senior-dev's model said: …`) and what senior-dev saw when it ran the project's build +and tests (`senior-dev observed: …`). Read the second for "did it work". + +**A run you stop keeps its work the same way**: the stop says `its work so far stays on +its branch <branch>, checked out in <folder>` at once, and the page then says where it is +in the words above. A merge senior-dev's shell left half done is never committed: the +page says what it left `could not be committed (<folder> is in the middle of a merge)`. + +**A run that changed nothing leaves nothing**: your own branch is checked out again, its +empty branch is deleted, and the page says `it changed nothing, so <folder> is back on +your branch <yours> and its branch <branch> was deleted`. + +## Does senior-dev change my branch — your branch never moves, going back, a HEAD it moved, my branch moved during the run + +No. Your branch (or, when your checkout was on no branch, the commit it was on) is +written down before senior-dev starts, and codeaf never writes to it, resets it or +merges into it. After the run your folder is on senior-dev's branch; `git -C '<folder>' +switch <yours>` goes back, and the page names the exact command. From no branch it +names `git -C '<folder>' switch --detach <commit>`. codeaf's own switches run with your +repository's hooks turned off: both go between two names for one commit, so a hook has +nothing to do there. + +senior-dev's shell can still run `git checkout`, and a brief that says "work on a new +branch" makes that likely. **So a brief need not ask for a branch: the work already has +one.** If HEAD is not on its branch when the run ends, nothing is touched, and the page +says where HEAD is: `senior-dev left <folder> on the branch <other> instead of its own +branch <branch>, so codeaf changed nothing there: nothing was committed and nothing was +switched; <branch> holds N files` (or `on no branch, at <commit>`). + +**codeaf reads your branch again before it says it is as it was.** If something moved it +during the run, the page says `your branch <yours> moved during the run, from <commit> +to <commit>, and codeaf did not move it: look at it before you push or merge it`, and a +run that changed nothing is not switched back onto it: `it changed nothing, but your +branch <yours> moved during the run, from <commit> to <commit>, so codeaf did not switch +back to it: its empty branch <branch> is still checked out in <folder>`. A branch deleted +meanwhile reads `your branch <yours> is gone: it was at <commit> when the run began, and +codeaf did not make it again`. + +## senior-dev refused: changes that are not committed — a dirty checkout, uncommitted changes, a merge in progress + +senior-dev works in your checkout itself, so it starts only on a clean one. **A repository +with changes that are not committed — modified, staged or untracked files — is refused +before anything starts**, nothing is switched and nothing is spent: `<folder> has changes +that are not committed (a.go, b.go, c.go and 2 more); commit or stash them, then ask +again`. senior-dev's own `.senior-dev/` does not count. A checkout in the middle of a +merge, a rebase, a cherry-pick or a revert is refused the same way: `<folder> is in the +middle of a merge; finish it or abort it, then ask again`. + +In the chat the model is told this before you are shown a card, and can commit or stash +the changes itself if you ask it to; at a shell the run prints `error:` and the sentence, +and leaves. + +## senior-dev refused: the folder is busy — one run per folder, a folder inside it, another window, a shell run + +One folder takes one senior-dev run at a time, from any conversation, any window or a +shell. A second is refused, naming the one working there: `<folder> is busy: senior-dev, +task 4 (Fix the parser), is working in it, and one folder takes one program run at a +time; ask again when that run has ended` (or `senior-dev, a run started at a shell`). + +**So are the folders inside it, and a folder around it.** A run on a folder of projects +puts back whatever changed anywhere under it once it has submitted, so a run in one of +those projects is refused too, naming the folder held: `<folder> is busy: senior-dev, +task 4 (…), is working in <held folder>, which holds it, and one folder takes one program +run at a time; ask again when that run has ended` (`which is inside it` the other way +round). Two runs in two folders side by side both go. + +The hold goes with the codeaf holding it, however it ends, so a crash never leaves a +folder refused. + +## What a senior-dev run costs — model calls, the dollar ceiling, which models + +Every model call senior-dev makes goes through codeaf, which serves each run its own +model API. So every call is priced like one of codeaf's own, shows in the conversation's +total, its tokens and its call count, under `tasks` in `/cost`, and under the task on the +spend place. What the whole run came to is on its row, its landed card once opened +and the chat's `tasks` tool (`#3 · … · done · ran 22m 51s · $2.30 · via senior-dev`). +Every call is held to the run's dollar ceiling: **once the run's spend has +reached it, codeaf refuses every further call** before it is made, with +`the run's dollar ceiling of $5.00 is reached ($5.04 spent), so codeaf made no call`. +The call that crossed the ceiling was already made and paid for, so a run can end a little +over it. A refused call ends senior-dev's turn; it runs the project's build and tests on +the tree it has, and ends there, and the task says +`senior-dev reached the run's dollar ceiling of $5.00: …` with senior-dev's own words +after it. A run handed off after the conversation's dollar limit is already spent starts +nothing and makes no call: its row ends at once with `a dollar limit you set stopped it`. + +The time ceiling is kept by senior-dev as well as by codeaf. It holds back the last part +of its time to land: two fifteenths of the run, at least 45 seconds, at most 12 minutes, +and never more than a quarter of it. When that window opens it gets one last turn to +submit. + +**When none of your model services can serve the model it asks for**, codeaf answers the +call on the run's own work model — the one a task's own worker would use — and the raw +calls on the task page (`ctrl+y`) name the model that answered. When nothing here can serve +that model either, the conversation's own model may answer instead, and the page names +whichever model did. A dated build or a variant of the model it asked for, such as +`deepseek/deepseek-v4-pro-0731` or `qwen/qwen3.6-plus:free`, is that model and is not named +again; a sibling such as `openai/gpt-5.5-mini` answering for `openai/gpt-5.5` is a different +model and is named. Which models it asks for is the next section. + +## senior-dev on a service that reports no prices — a local proxy, a Codex sign-in, the dollar ceiling does not hold, set a time limit + +Some model services answer without saying what a call cost: most of the services you +connect in `/connect` besides the default router, such as a local proxy or runner, a +vendor's own API, or a plan you signed in to such as Codex. codeaf never guesses a price, +so each call +senior-dev makes through one is counted with its tokens and no dollars. The task page, +the rail and the spend place show no money for those calls, never `$0.00`, and a missing +price does not mean the service charged nothing. + +**So the dollar ceiling cannot hold there.** A run whose calls report no price never +reaches its dollar ceiling, whatever it is set to, and senior-dev's own `--max-cost` adds +up the same missing figures. codeaf does not refuse such a run or estimate its cost. + +**On such a service the bound that holds is a time limit.** Start codeaf with +`--max-hours`, or give a shell run `--max-hours`, before you hand the work off. With no +time limit, the run ends only when senior-dev finishes or you stop it. + +## Why a stopped senior-dev run takes a moment to end — the price of the call it was in the middle of + +When you stop a run, or codeaf ends it at its dollar ceiling, senior-dev is usually in +the middle of a model call. That call is still paid for, and the router prices a call cut +off like that by a receipt codeaf fetches afterwards, usually about twenty seconds later. +**The run is not over until that receipt is in**, for at most 70 seconds, so the task's +spend, the run's total and the conversation's `/cost` all include that call. A shell run +waits the same way before it prints its last line. + +A receipt that never comes is kept as a call nobody could price, never as a free one +(the section `Was I charged for a reply that got cut off` says where those are counted). +A senior-dev call answered whole whose answer carried no usage block at all is asked +about the same way, including one codeaf then set aside because it was not usable text: +priced by its receipt, or kept as a call nobody could price. codeaf never guesses a figure +for either. + +## Which models does senior-dev use — your crew, a model you ask for, its own list, --high + +**Ask for a model and it works with that one.** Say which in the chat — "use senior-dev +with kimi-k2.6", or several: "with kimi-k2.6 and deepseek-v4-pro" — and senior-dev works +with exactly those, routing among them call by call when there are several; the card and +the task's first line name them. A name that fits more than one model is put to you to +settle. A model none of your connected services can serve is refused before the card, by +name, rather than swapped for another. A model senior-dev's model catalog does not know how to size cannot be used: the +run ends before its first call with `senior-dev cannot work with <model>: …`, and nothing +is spent. The models are fixed when the run starts; changing the crew later does not move +a run already working. `/senior-dev` typed with a brief uses your crew. + +**Otherwise, from the chat it uses your crew.** codeaf hands senior-dev two of the conversation's +crew: the worker (hands) model is the one it works with, and the low model its history +summaries. Change the crew and the next run follows. The mastermind (brain) model is not +used: every call senior-dev makes is either its work or a history summary. +A crew model senior-dev's model catalog cannot size is left out, and its log says so; +if that leaves no working model, it uses its own list instead. + +**Its own list** is six open models it routes among call by call, avoiding one for a +while after it fails: deepseek-v4-flash, deepseek-v4-pro, qwen3.6-plus, kimi-k2.6, +glm-5.1 and minimax-m2.7. A run with no crew set uses it, and so does a shell run. + +**At a shell you choose**: `--high` replaces the list, `--low` sets the summaries' models, +and `--variant` sets the reasoning effort every call asks for. + +## What a shell run prints at the end — how long senior-dev ran, what it cost, waiting for the last price, a closed terminal + +At a shell, `codeaf senior-dev` first says where it works (`senior-dev · working in +<folder>, on its own branch <branch>` in a repository), then prints each stage, step and +model call as it happens, then how the run ended, then where its work is (the sentence a +task's page says), then `the run's record is in` and the run's record folder, and last one +line with what it came to: + +``` + 277 model calls · $2.30 · 22m 51s +``` + +That is the calls, the dollars, and how long senior-dev's own process ran. A figure nobody +measured is left off, never written as a zero. + +When ctrl-c or `--max-cost` stops the run in the middle of a model call, that call is still +paid for, and its price arrives by a receipt about twenty seconds later. The run waits for +it before those last lines, and says so on stderr: +`waiting up to 1m 10s for the price of 1 call that was cut short`. **A second ctrl-c leaves +at once** instead of waiting; its folder is already finished by then, and only a price +still owed is missing from the run's line and from this machine's spending ledger. + +**A closed terminal or a dropped ssh connection stops the run the way ctrl-c does**: +senior-dev is stopped and its folder finished. If the codeaf running it is killed +outright, senior-dev sees within a second that it is gone and stops; its folder is then +settled by the next run started there, without a commit (see `If codeaf quits while +senior-dev works`). + +Every call is written to this machine's spending ledger, filed as one piece of work named +after the run's record folder (such as `20260924-150405.000000`).

Readying the folder before it, and committing what it left after it, are +not counted. A run whose senior-dev never started is timed to the moment the run ended. + +Everything that shows the run's time shows that one span: the line under its page's title +(counting up from the hand-off while it runs, and stopped at senior-dev's exit once it has +ended, even before its last changes are committed), its row and card once it has ended, the note the +conversation is handed when it lands (`done · ran 22m 51s · …`), and the chat's `tasks` +tool (`#3 · <title> · done · ran 22m 51s · via senior-dev`, or `running for 3m` while it +goes) — so you can ask the chat how long it took. Each spells it the way the page does — `42s`, `22m 51s`, +`1h 7m` — except the landed card, which spells it `22m51s`. + +The instants senior-dev's process started and ended are also kept in `delegate-program.json` +in the task's record folder, beside `delegate-stderr.log`. + +**After a reopen.** A conversation closed and opened again still shows each run's time, how +it ended in senior-dev's own words (a `senior-dev did not finish: …` stays that sentence and +is not turned into a fault), which limit stopped it when one did, `stopped` when you stopped +it, and the branch its work is on. + +**A run nothing is running any more.** If codeaf closed or crashed while senior-dev was +working, nothing is driving that run: its page reads `incomplete` rather than `running`, +its time stops at the last thing it did, and it offers no stop. + +## Does another conversation or window see my senior-dev run — the @ list, other windows, the project's task list, watching it from another window + +Yes.

The paragraph said a +// large task "can" go to one, which is a permission, and a permission loses +// to the two roads the rest of the section teaches: an issue in a mature +// project is worked through inline, or handed to codeaf's own worker, which +// has none of a program's machinery for that work. The owner's call of +// 2026-09-24 is that codeaf reach for a program by itself on complicated, +// many-sided coding work, and almost always when the person asks for one. So +// the first sentence is a preference over both of those roads, the program's +// guide under it says which work that is, and WHATEVER ITS CRITICAL PATH is +// said because the section's own test for a hand-off is the critical path: +// one hard fix has a single one, and a model holding that test alone would +// keep the fix. The second sentence is the person's ask, which outranks the +// section's floor on small work; code holds both halves of it, where a prompt +// would be forgotten (delegate_asked.go). +// +// THE TWO SENTENCES STAND APART FROM THE FOLDER RULE, which is spliced in +// after them, so either can be reworded without touching the other. +var delegateFact = beltFact{ + tools: []string{"propose_task"}, + holds: Config.mayDelegate, + present: "AND WORK A PROGRAM BUILT INTO CODEAF IS FOR GOES TO IT WHOLE, named in\n" + + "`propose_task`'s `via`, rather than to you or a worker, whatever its critical path;\n" + + "so does work the person asks one for, by name or as `/name`.%s The programs here:\n%s", + fill: func(config Config, text string) string { + rule := "" + if config.carriesTreeProgram() { + rule = delegateFolderRule + } + return fmt.Sprintf(text, rule, config.delegateGuides()) + }, +} + +// delegateFolderRule is codeaf's one sentence about the folder a program that +// edits files is handed, and it is printed only when the build carries one. +// +// IT EXISTS BECAUSE A MODEL SENT SENIOR-DEV TO THE WRONG REPOSITORY.
