feat(skills): route agents to devkit review, and make an unrouted CLI verb fail typecheck (sc-2361)

[norvalbv]

Closes sc-2361.

devkit review runs the configured pre-commit chain — deterministic gates, decisions gates and the AI reviewer fleet — against the working tree with no branch, commit, push or PR. Nothing in skills/ named it. grep -rn "devkit review" skills/ returned zero hits, and zero across templates/ and agents/ too; no commit on main ever added them.

An agent only learns a verb exists by reading skills/. So the lane was unreachable in practice, and agents discovered reviewer findings one full ship cycle at a time — the reporting run spent 11 devkit ship attempts on a single 10-file PR, 8 of them blocked by the AI stage, each paying the full reviewer fan-out plus a push-then-delete on origin.

What changed

Routing. skills/using-devkit/SKILL.md gains a devkit review row beside the existing --dry-gates row, a Rules bullet for the three-lane division, and one frontmatter clause. The clause matters: the description is the skill's only firing surface and enumerated git/maintenance triggers only, so without it a row about pre-ship review would never be read.

A mechanism, so this cannot recur. CommandMeta.agentFacing is now required. COMMANDS in cli/index.mts is annotated, so a new command that never classifies itself fails typecheck at its own registration line — classifying is part of adding a command, not a follow-up. cli/__tests__/command-skill-routing.test.mts then enforces what the type cannot: that true was followed through into skills/, and that false carries a notRoutedBecause a human can check.

The audit that forced. review was not the only one. Three further agent-facing verbs were unrouted and are now routed — base-status (using-devkit), baseline-status and prove-regression (skills/testing, phrased runner-agnostically). Eight verbs are classified internal with written justifications: hook shims, wired package scripts, maintainer-only, and upgrade slices.

What the routing row deliberately does not claim

Three corrections to the story's premise, each verified in source, because a row that overpromises is worse than no row:

• Review does not run the completeness judge. .husky/pre-commit:198 gates it on DEVKIT_RUN_MODE != "review", and the comment at :190 says why — completeness is a commit gate, not part of a range review. Sentry is excluded too. The row says so, because a green review followed by a completeness block would otherwise read as the tooling contradicting itself. Two of the reporting run's eight blocks were completeness, so this lane would not have caught them.
• Review does not warm ship's cache. Its persistent store is checkout-external (cli/lib/ship/review/cache/root.mts); ship reads the repo's .devkit/review-cache.json. The row states that ship re-pays every judge.
• Review is early signal, never a ship guarantee. It covers merge-base..HEAD plus the whole dirty snapshot where ship covers only briefed paths. This restates the sc-2346 rejection in ship-gates-converge-not-restart.md:44 as guidance rather than re-litigating it.

Two lanes are deliberately not named. Ship's gate-failure footer is untouched: ship-gates-converge-not-restart names commit-with-gate-capture.sh literally in its Scope, and review earns a blocked --resume nothing. And on a non-protected branch a plain git commit already runs the same fleet on the same cache salt family, so the Rules bullet sends agents there first and scopes review to the protected-branch / cannot-commit case.

Scope cut from the story

• The gate-failure footer AC — see above.
• Re-scoping sc-2346: already resolved. --dry-gates shipped as 77308735 / feat(ship): add deterministic dry-gates rehearsal (sc-2346) #523 and is routed at SKILL.md:40.
• The proposed --deterministic-only flag on devkit review — explicitly rejected in the decision log; --dry-gates covers the fast inner loop.

Testing

45 tests in the new suite; full CLI suite 175 files, 2909 passed, 0 failed.

Every guard was verified to fail when its target is broken, then reverted. The interesting one: replacing the routing matcher with the naive \b<verb>\b form the design rejected left all 14 gate assertions green while the gate became meaningless. That blind spot is why the suite also unit-tests the predicate directly — 14 boundary cases pinning that a backticked bare `guard-branch` is not routing (the reason it is classified internal), that devkit review-all does not satisfy review, and that a line-wrapped devkit\nreview does not count.

diffRegistry gets its own units because it cannot be exercised through the real tree at all: renaming a meta.name moves both sides together, since devkit --help renders from the same modules. Confirmed experimentally — that mutation produces exactly one failure, from the separate verb-collision guard, which exists because two modules claiming one name would otherwise have a classification silently dropped.

Notes

• A decision note is recorded under the existing review-gate-in-chain axis, not a new one.
• .claude/, .cursor/ and .devkit/skills-manifest.json are devkit sync-skills output and are included so doctor stays clean.
• qavis advisory bypassed — headless flow run, no visual QA.

Unrelated-looking line in the diff, explained: cli/commands/init.mts sat exactly at its 1154-line shrink-only ceiling, so adding one agentFacing field tripped guard-size. Rather than override it, the redundant one-line structureAvailableFor wrapper is inlined — the file already bypassed it at one of four call sites, so all four now read identically and the file nets to 1151.

Allowlist entry, explained: guard-dup blocked on reconcile (cli/commands/reconcile.mts) vs reconcilePath (cli/lib/reconcile.mts) at c=0.8342. I read both ranges: the first is the CLI entrypoint (flags, git-top-level assert, manifest load, render), the second decides restore/delete/warn for one path from upstream/worktree/index blobs. No shared logic — the matcher scored shared reconcile-domain vocabulary and a common guarded-early-return shape. It is a pre-existing latent pair that surfaced only because the one-line agentFacing field put the commands file into the staged set, so it is approved via the gate's own documented path with that reasoning recorded, not overridden.

📝 Walkthrough

Walkthrough

The change classifies CLI commands for agent routing, adds registry and skill-coverage tests, documents review and regression workflows, refreshes skill manifests, updates an init baseline, and records a verified co-occurrence false positive.

Changes

Command routing classification

Layer / File(s)	Summary
Command metadata contract and classifications cli/lib/help/render.mts, cli/commands/..., .devkit/baselines/size-lines.json	CommandMeta now requires agentFacing. Non-routed commands provide notRoutedBecause. Command descriptors are classified, and init uses direct stack membership checks.
Command and skill routing validation cli/__tests__/command-skill-routing.test.mts	New tests compare command modules with help output, detect duplicate names, validate routing metadata, and require agent-facing verbs in skills.
Agent workflow and testing guidance .claude/skills/..., .cursor/skills/..., skills/..., docs/decisions/..., .devkit/skills-manifest.json	Skill documentation adds baseline-status, prove-regression, review, and base-status guidance. The decision record defines routing rules, and provider manifest hashes are refreshed.

Allowlist maintenance

Layer / File(s)	Summary
Reconcile false-positive record .co-occurrence-allowlist.json	The allowlist records a verified false-positive match between reconcile and reconcilePath.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to a1774

The routing classification is not fully enforced at typecheck time, and the stale init size baseline can block the size gate. Both should be corrected before merge.

Update the init.mts size baseline.

The baseline still records 1151. guard-size rejects growth above this shrink-only ceiling. Set the value to 1154 when this change increases cli/commands/init.mts to 1154 lines.

Require the false branch at typecheck time and type the command metadata.

CommandMeta currently accepts agentFacing: false without notRoutedBecause. Replace the interface with a discriminated union, then annotate each command's meta export with CommandMeta or satisfies CommandMeta. Otherwise the dynamically imported metadata remains inferred independently of the union. Keep the routing test for registry coverage.
