This document describes how to extend it with custom tools, skills, hooks, and integrations. -- **Library** — importable Go library + embeddable MCP server (no CLI binary) -- **No LLM dependency** — pure static analysis on crawled pages -- **Extensible** — custom checks (Go code) + declarative rules (no code required) +## 1. Drop a project `AGENTS.md` -## Build & Test +When hawk-eco starts in a directory, it looks for project-level instructions and injects them into the system prompt. The lookup walks from your current working directory **up to the nearest git root** and reads the first matching file at each level — general rules at the repo root, more specific rules in sub-trees. Files are labeled with their directory in the prompt (e.g. `## Project guidelines (services/api/AGENTS.md)`). + +Accepted file names, in priority order at each level: + +| Path | Notes | +| --- | --- | +| `./AGENTS.md` | The classic spot — committed to your repo, shared with the team. | +| `./ZERO.md` | Brand-specific alias. Same format, lower priority. | +| `./.zero/AGENTS.md` | Project-local, hidden, gitignored. Personal notes that stay out of git. | + +Matching is **case-insensitive** on the basename, so `AGENTS.md`, `Agents.md`, and `agents.md` resolve to the same file on Windows and macOS. The git-tracked filename in this repo is `AGENTS.md` — keep that on case-sensitive filesystems (Linux, the WSL filesystem, or a CI runner) to match what the loader looks for. + +Both files use the same format. YAML frontmatter is optional; the markdown body is loaded as instructions for the agent. hawk-eco reads the file once at session start, so changes take effect on the next launch — not mid-session. + +```markdown +# Project conventions for + +- Build with `make`, not `go build` directly. +- Tests live next to the source file (`foo_test.go` next to `foo.go`). +- Run `make lint` before opening a PR. +- Never edit files under `third_party/` — those are vendored. +``` + +Tips: + +- Keep each file under ~8 KiB. hawk-eco caps the **total** across all matched files at 32 KiB; everything past the cap is dropped. +- Re-state rules in the imperative voice: "Run `make lint`", not "you should consider running the linter". +- Don't put secrets, model IDs, or environment-specific paths in `AGENTS.md`. Use config files for those. +- In a monorepo, drop a narrower `AGENTS.md` in each sub-tree (e.g. `services/api/AGENTS.md`). hawk-eco picks those up automatically when you launch from inside the sub-tree. +- A YAML frontmatter block (`---\n...\n---`) at the top is preserved verbatim in the injected prompt but is not parsed for `globs:` or `alwaysApply:` scoping today — keep the body self-contained. + +### Personal guidelines, across every project + +For preferences that follow *you*, not a specific repo (tone, tooling habits, workflow), drop a `ZERO.md` in your user config directory: `~/.config/hawk-eco/ZERO.md` on Linux/macOS, `%AppData%\Roaming\hawk-eco\ZERO.md` on Windows — the same directory as config files and your personal specialists. Same format and 8 KiB cap as the project files above, and the same case-insensitive basename match. + +This file is injected as its own `## User guidelines` section, before the project's `AGENTS.md`/`ZERO.md`, and is labeled as personal preference in the prompt: project guidelines are the later, more specific instruction and take precedence over it when the two conflict. + +## 2.
