WalkthroughThe change adds OpenSpec documentation for setup-time provisioning of a shared, version-pinned ChangesMCP runtime setup
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This change adds the setup/runtime staging contract, but the current specification still leaves safeguards and validation incomplete for atomic publication, canonical path containment, child-process failure handling, and npm safety flags. Those gaps could cause partial setup or unintended runtime/package selection, so merge should wait for the requirements and tests to be tightened or explicitly accepted. Suggested reviewers: Poem

Walkthrough
This PR adds an OpenSpec change record (stage-mcp-runtime-during-setup) describing the plan to provision the mcp-remote@0.1.38 bridge runtime during nsolid-plugin setup rather than lazily via npx at MCP startup. The change folder contains the four standard ns-workflow files: proposal (problem, solution, affected files, success criteria, rollback), design (module contract for mcp-remote-runtime.ts, install sequence, npm resolution, wrapper contract, doctor, concurrency/failure model, lifecycle, security notes), a spec delta under installation-and-auth with five new requirements and 12 scenarios, and a 9-group tasks breakdown. No source code, tests, or generated artifacts are modified — this is a docs-only spec PR.

The design (step 4) specifies --save-exact, but the tasks list describes the flag as --ignore-exact. This appears to be a typo — --ignore-exact is not a valid npm install flag, and it contradicts the design's intent to exact-pin mcp-remote@0.1.38. The design and spec both require exact pinning, so the task wording should read --save-exact to match.

Re-checked at head 47ff0e3 (synchronize): still open. tasks.md line 26 still reads --ignore-exact flag set per design, which contradicts design.md step 4 (--save-exact ... --no-package-lock). --ignore-exact is not a valid npm flag — an implementer copying this list would produce a failing npm invocation. The fix is the one-line suggestion in the original comment (--save-exact).

🛠️ Refactor suggestion
The mermaid sequence diagram uses Spanish labels (Usuario, nsolid-plugin setup, autenticar solo si..., Runtime estable, MCP remoto NodeSource) while the rest of the design document is in English. Mixing languages inside an English-language spec may confuse readers and downstream tooling. Consider translating the participant aliases and messages to English for consistency, e.g. participant U as User, S->>A: authenticate only if credentials missing/expired, participant R as Stable runtime ~/.agents/..., participant M as NodeSource remote MCP.

Re-checked at head 47ff0e3 (synchronize): still open (non-blocking). The mermaid block in design.md still uses Spanish participant/message labels (Usuario, autenticar solo si..., Runtime estable, MCP remoto NodeSource) in an otherwise English document. Translating to English keeps the spec consistent for downstream readers/tooling.

🧹 Nitpick
The tasks reference /tmp/nsolid-plugin-npm-execpath-fix-handoff.md and the proposal references /tmp/nsolid-plugin-mcp-runtime-setup-handoff.md — both are local /tmp paths that won't exist outside the original authoring machine and won't survive reboots. For a durable spec record, consider summarizing the handoff contents inline or moving it under docs//docs/technical-debt/ so reviewers and future maintainers can actually find it.

- Around line 105-123: The MCP wrapper’s readiness check must match the setup
predicate by validating the complete non-optional dependency closure before
importing the runtime, or by translating missing-dependency import failures into
the required repair message naming the launching harness. Update the wrapper
test matrix to cover a runtime with a missing transitive dependency and verify
it fails fast with the setup command.

- Around line 36-42: Update the all-harness setup dispatcher in
packages/core/scripts/setup.mjs to invoke ensureMcpRemoteRuntime() before
selecting setup() versus install(), or route both paths through a shared

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Make replacement publication atomic across existing directories.
The root → root.stale-* rename followed by staging → root creates an observable gap. A process kill or concurrent setup can leave the versioned root missing after staging validation. This does not meet the interrupted-install and concurrent-setup guarantees. Serialize publication with a lock and recovery protocol, or use a platform-safe atomic swap design. Add a test that interrupts publication between the two renames.

This is a docs-only OpenSpec change record describing the plan to provision a shared, version-pinned mcp-remote@0.1.38 runtime during nsolid-plugin setup instead of lazily via npx at MCP startup. The new commit resolves the prior review findings and several CodeRabbit findings: the npm flag typo, the mermaid diagram language, the /tmp handoff references, the untrusted npm_execpath trust, the execution-scoped "no npx" wording, the NpmRunner timeout/cancellation contract, the dependency identity/version validation, the version-pinned repair command, the dispatcher precondition for OpenCode/Pi, and the shell-fence language tag.

Scenarios cover fakenpm-cli.js, renamed entry points, symlink/path escape, and supported Node/npm layouts. - ✔ CodeRabbit "no npx" scoping (resolved,
design.mdwrapper contract): the prohibition is now execution-scoped — the wrapper never executes or spawnsnpx, npm,cmd.exe, or a shell; the repair message may contain annpxcommand as text. - ✔ CodeRabbit
NpmRunner.runtimeout cancellation (resolved,design.md/spec.md): the contract now requires terminating the managed npm process tree and confirming it stopped before cleanup; Unix uses a detached process group with SIGTERM → SIGKILL escalation and group-disappearance polling, Windows awaitstaskkill /T /F; unconfirmed termination leaves staging inert withterminationError. - ✔ CodeRabbit dependency identity/version validation (resolved,
design.md/spec.md): readiness now verifies each transitive's resolvedpackage.jsonhasnameexactly matching the requested dependency andversionsatisfying the declared semver range, with resolution confined to the runtime root; wrong-named, incompatible-version, and missing-transitive scenarios added. - ✔ CodeRabbit version-pinned repair command (resolved,
proposal.md/design.md): the repair message now embeds bothMCP_REMOTE_VERSIONandPLUGIN_VERSION—npx -y nsolid-plugin@<PLUGIN_VERSION> setup --harness <harness>— so the printed command recreates exactly the runtime version the wrapper validates even when a newer CLI exists; a sync test is specified. - ✔ CodeRabbit dispatcher precondition (resolved,

- 🚩 The change record describes a future security-sensitive refactor (npm resolution, MCP bridge runtime, OAuth scope, credential-adjacent paths). The spec itself is documentation; the implementation PR that follows will touch auth-adjacent paths (
X-Nsolid-*headers,~/.agents/.nodesource-auth.jsoncredentials handling) and should get a dedicated human reviewer.
Verdict: APPROVE — all prior blocking findings are verifiably resolved in the code at the new head, and the commit also addresses the open CodeRabbit findings; no new issues introduced. Advisory only — does not replace required human review.

Walkthrough
Re-review at head 5ab5a8e (synchronize from 555d9dc). This is a docs-only OpenSpec change record describing the plan to provision a shared, version-pinned mcp-remote@0.1.38 runtime during nsolid-plugin setup instead of lazily via npx at MCP startup. The new commit (5ab5a8e, "address follow-up MCP runtime review") tightens the development-fallback gate, replaces the ambiguous "inert staging" wording with a precise retained-live ownership state plus a conservative safe-reclamation protocol, and adds spec scenarios for symlink-escape rejection, dependency-kind semantics, retained-live staging, orphaned-stale reclamation, project-dependency bypass prevention, explicit dev-mode fallback, and expanded doctor bridge states. No source code, tests, or package manifests changed.
Changes
| File(s) | Summary |
|---|---|
openspec/.../design.md |
Canonical realpath boundary check for mcp-remote, transitives and dist/proxy.js before metadata read; ownership sidecars for staging/stale trees; retained-live staging state replacing "inert"; new ### Safe orphan reclamation section (grace period, proven-dead creator, managed-tree absence, lock-token exclusion); dev fallback now gated behind explicit NSOLID_MCP_RUNTIME_DEV_FALLBACK=1; separated MCP_REMOTE_VERSION / PLUGIN_VERSION assertion domains. |
openspec/.../proposal.md |
Acceptance criteria 5/9/12 reworded (retained-live reclamation, canonical symlink boundaries, separated version-domain assertions). |
openspec/.../specs/installation-and-auth/spec.md |
New scenarios: Runtime package symlink escapes are rejected, Dependency kinds follow runtime-install semantics, Potentially live staging is retained until reclamation is safe, Orphaned stale trees are reclaimed conservatively, A project dependency cannot bypass the managed runtime, Explicit development mode permits only the pinned fallback; doctor requirement split into Required wrapper bridge missing is unhealthy, Ready wrapper bridge reports local readiness only, Non-wrapper bridge state is informational; wrapper requirement retitled ...uses the stable runtime by default. |
openspec/.../tasks.md |
Inspect task gains symlink-escape + dependency-kind coverage; timeout task references retained-live + safe-reclamation; wrapper task gates dev fallback on NSOLID_MCP_RUNTIME_DEV_FALLBACK=1; test lists expanded for symlink, dependency-kind, dev-mode, and doctor-bridge-matrix coverage; MCP_REMOTE_VERSION / PLUGIN_VERSION assertions separated. |
Assessment

design.mdL301–306 at prior head): the fallback is now gated behind an explicit internalNSOLID_MCP_RUNTIME_DEV_FALLBACK=1flag, with a new spec scenario (A project dependency cannot bypass the managed runtime) asserting the projectnode_modulescannot mask a missing/invalid managed runtime when the flag is absent. Released harness configs never set it. - ✔ CodeRabbit "inert" staging wording (
design.mdL374–380 at prior head): staging with unconfirmed managed-tree termination is now described asretained-liveand excluded from publication/cleanup, with ownership sidecar metadata; a new### Safe orphan reclamationsection defines the conservative grace-period-based reclamation (proven-dead creator, managed-tree absence, lock-token exclusion). The term "inert" now correctly applies only to genuinely-inert stale-aside trees from interrupted replacements. - ✔ CodeRabbit symlink-escape (

tasks.mdL134–137):MCP_REMOTE_VERSIONandPLUGIN_VERSIONassertions are now separated — neither domain is compared to the other. - No new blocking or non-blocking issues introduced by
5ab5a8e; the docs-only diff is internally consistent (design ↔ spec ↔ tasks ↔ proposal all reference the sameretained-livestate, sidecar metadata, and reclamation protocol). - No execution validation performed — docs-only diff, no code/tests/manifests changed.
- 🚩 The change record describes a future security-sensitive refactor (npm resolution, MCP bridge runtime, OAuth scope, credential-adjacent paths). The spec itself is documentation; the implementation PR that follows will touch auth-adjacent paths (
X-Nsolid-*headers,~/.agents/.nodesource-auth.jsoncredentials handling) and should get a dedicated human reviewer.
Verdict: APPROVE — all prior blocking findings remain verifiably resolved in the code at the new head, and commit 5ab5a8e addresses the remaining open CodeRabbit findings and introduces no new issues. Advisory only — does not replace required human review.

338-359: 🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy liftApply canonical containment checks before wrapper import.
The readiness predicate requires canonical package, manifest, and proxy targets to remain inside the canonical runtime root. Wrapper startup checks only the package name, exact version, and proxy file. The design also skips revalidation after external mutation. A changed package or proxy symlink can therefore pass wrapper checks and load code outside the managed runtime. Add the canonical-boundary check before import. This need not repeat the full semver closure walk.

Re-review at head dfc2d4d (synchronize from 5ab5a8e). This is a docs-only OpenSpec change record describing the plan to provision a shared, version-pinned mcp-remote@0.1.38 runtime during nsolid-plugin setup instead of lazily via npx at MCP startup. The new commit ("docs(openspec): expand runtime safety test coverage") adds two test-coverage line items to tasks.md addressing the remaining open CodeRabbit threads: preservation of a pre-existing invalid runtime when npm or staging validation fails, and a direct npm sentinel test in stable-runtime and explicit dev-fallback modes. No source code, tests, or package manifests changed.

Two additive test-list entries under §6: (1) pre-existing invalid runtime (wrong version, missing proxy, or incomplete dependency closure) remains untouched when npm or staging validation fails; (2) direct npm sentinel never executed in stable-runtime and explicit dev-fallback modes, alongside the existing npx/shell/cmd.exe checks. |
Assessment
- ✔

design.md): no Spanish labels remain. - ✔
/tmp/...-handoff.mdreferences (non-blocking): none remain in the change record. - ✔ CodeRabbit dev-fallback bypass, "inert" staging wording, symlink-escape, dependency-kind rules, doctor bridge matrix, version-domain separation, canonical npm resolution, execution-scoped no-npx wording, NpmRunner timeout cancellation, dependency identity/version validation, version-pinned repair command, dispatcher precondition, shell-fence language tag — all resolved at prior heads and unaffected by
dfc2d4d. - ✔ CodeRabbit pre-existing-invalid-runtime test gap (discussion_r3823172096): the new line item in
tasks.md§6 adds coverage for wrong-version, missing-proxy, and incomplete-dependency roots when installation or staging validation fails, guarding rename-aside recovery — consistent with the design's publication protocol step 4 ("An invalid staging takes the failure path … and leavesrootexactly as it was"). - ✔ CodeRabbit direct-npm sentinel (discussion_r3823172101, was still open): the new line item in
tasks.md§6 adds a directnpmsentinel failing when spawned, in both stable-runtime and explicit dev-fallback modes — consistent with the wrapper contract ("The wrapper never executes or spawnsnpx, npm,cmd.exe, or a shell"). - No new blocking or non-blocking issues introduced by
dfc2d4d; the two additions are purely additive line items in a docs-only spec PR and are internally consistent with the design and spec. - No execution validation performed — docs-only diff, no code/tests/manifests changed.
- 🚩 The change record describes a future security-sensitive refactor (npm resolution, MCP bridge runtime, OAuth scope, credential-adjacent paths). The spec itself is documentation; the implementation PR that follows will touch auth-adjacent paths (
X-Nsolid-*headers,~/.agents/.nodesource-auth.jsoncredentials handling) and should get a dedicated human reviewer.
Verdict: APPROVE — all prior blocking findings remain verifiably resolved in the code at the new head, and commit dfc2d4d addresses the remaining open CodeRabbit threads with no new issues introduced. Advisory only — does not replace required human review.
