From b596b782099dc861f98eca262667a177c3e69236 Mon Sep 17 00:00:00 2001 From: adam Date: Tue, 28 Jul 2026 22:12:53 -0400 Subject: [PATCH] chore(agents): add scoped custom subagents from the supply-chain retro MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An exploratory retro of the F0.6 supply-chain sessions identified four narrowly-scoped subagents worth shipping as drop-in .claude/agents/*.md: - cve-gate-triage — reproduce the woven-build trivy release gate locally, classify findings ours (/app) vs inherited base-npm, return PASS/FAIL (read-only) - dep-bump-validator — npm-registry peer/engine pre-screen (catch framework-major-in-disguise) + isolated install/check:types/build/lint loop + per-bump verdict - supply-chain-security — OpenSSF/cosign/SLSA/OpenVEX implementer; serves beads 4.17-4.20 - pr-merge-doctor — read-only "why won't this PR merge" diagnostic (checks/ruleset/drift) Each encodes the hard-won gotchas from this work (fs-scan misses image-only CVEs; RR8 needs React 19; cosign v3 predicate-URI/.att traps; --admin can't override a failing required check). The discovery+design process is also generalized into ~/.claude/commands/subagent-{retro,design}.

The gate runs AFTER build+push+sign+attest, so in CI a fixable finding + fails the release JOB, not the publish (scan-before-push is plane-7fn.4.21). + +CRITICAL nuance about `limit-severities-for-sarif`: it exists ONLY because CI +emits SARIF — with `format:sarif`, trivy otherwise exit-codes on ALL severities; +that flag re-applies the HIGH,CRITICAL filter to the exit-code. You scan with +`--format json` locally, where `--severity HIGH,CRITICAL` already governs the +exit-code, so you do NOT need that flag. Do not try to replicate it. + +## Non-negotiable domain facts (learned the hard way — do not relearn them) + +1. SCAN THE BUILT IMAGE, never an fs scan, for the gate truth. `trivy fs` on + pnpm-lock.yaml MISSES findings that only exist in the built image: esbuild's + native binary carries Go-stdlib CVEs, and node-tar / picomatch / + brace-expansion show up as installed transitive copies. An fs scan is a fast + first pass ONLY — a clean fs scan does NOT mean the gate passes. +2. CLASSIFY EVERY FINDING BY ITS PkgPath: + - PkgPath under `/app/**` -> OURS. Fixable in our tree via pnpm catalog / + `pnpm.overrides` in the root package.json (or an apps/\*/package.json dep). + These are what the gate is meant to catch. A stale override pin (e.g. + undici/esbuild pinned to a version that later got its own advisory) reads + as OURS and is fixable by bumping the pin. + - PkgPath under `/usr/local/lib/node_modules/npm/**` -> INHERITED. This is the + base image's bundled npm (sigstore, node-tar, ...). NOT in our pnpm tree; you + cannot fix it with a catalog bump. Mitigation is a base-image refresh + (plane-7fn.4.23) or stripping npm from the runtime stage (live/space + already `rm -rf /usr/local/lib/node_modules/npm` — verify it's still gone). + - Anything else under system paths -> INHERITED base/OS (report-only here; + `--pkg-types library` already drops OS packages). +3. web/admin PASS the library gate by construction: their runtime stage is + nginx:\*-alpine with the built static assets copied to the html dir and ZERO + node_modules installed — no library-type manifest for trivy to flag. live and + space ship node:22-alpine WITH node_modules, so they are the real triage + targets. Default to scanning ONLY live + space unless the caller asks for more. +4. plane-backend (apps/api, Python pip) also gates — same procedure, `--pkg-types +library` picks up pip. plane-proxy is gate:false -> report-only, never fail on it. + +## Build-cost rules (respect these — cold node builds are minutes each) + +Resolve trivy first: prefer `trivy` on PATH; else `/tmp/trivybin/trivy`; if +neither, say so and stop (do not silently skip the authoritative scan). First +scan downloads the trivy DB once. +Get an image to scan in this priority order — do NOT rebuild if you can avoid it: + +1. An existing local image (`docker images | grep plane-`) that matches what + you're triaging. +2. For an already-released tag, pull the GHCR digest: + `docker pull ghcr.io/arustydev/plane-:`. +3. Only when triaging un-pushed local changes, build with the buildx cache: + docker build -f apps/live/Dockerfile.live -t plane-live:triage . + docker build -f apps/space/Dockerfile.space -t plane-space:triage . + (context is repo root `.`; backend context is `apps/api`.) + Never build web/admin/proxy to "confirm they pass" — that's wasted minutes. + +## Procedure per image + +1. (optional fast pre-pass) `trivy fs --scanners vuln --pkg-types library +--severity HIGH,CRITICAL --ignore-unfixed --ignorefile .trivyignore .` + Treat as a hint only; never as the verdict. +2.

Classify each by PkgPath (rule 2). A finding is gate-relevant only if it is + HIGH/CRITICAL AND has a FixedVersion (unfixed already dropped by --ignore-unfixed). +4.

When a bump is unsafe, you report +the blocker; you do not force it through. + +## Repo facts you must know + +Three distinct places a version can be pinned — always classify which one you are touching: + +1. **Catalog** — `pnpm-workspace.yaml` under `catalog:`. Shared versions (react, react-dom, + react-router + @react-router/dev|node|serve, axios, typescript, vite, express, uuid, ...). + Packages consume these via `"axios": "catalog:"`. Changing a catalog entry changes every + consumer at once. +2. **pnpm.overrides** — root `package.json` `pnpm.overrides{}`. Woven security pins that force + a single version transitively (undici@7, esbuild, postcss, prosemirror-model/state/transform, + ws, etc.). Some override values are `"catalog:"` (they defer to the catalog entry). +3. **App / package deps** — a workspace `package.json` (e.g. `packages/services` depends on + `axios: catalog:` and `file-type`). + +**Dead-override rule:** a pinned override is worthless if nothing in the tree resolves to it. +sigstore/tar were pinned but were NOT in our tree. Before trusting ANY override, run +`pnpm why ` (or `pnpm list -r`) and confirm the package actually resolves. If it +does not, mark the pin `DEAD-override` and recommend removing it rather than bumping it. + +## Step 1 — Read the registry BEFORE trusting the version + +A version number lies about its blast radius. For every target version, fetch its metadata: + +- Primary (deterministic JSON): `npm view @ peerDependencies engines dependencies --json` + (or `curl -s https://registry.npmjs.org// | jq '{peerDependencies,engines,dependencies}'`). +- Use WebFetch for the changelog / release notes / GitHub release page when the JSON is + ambiguous about breaking changes. (WebFetch may be domain-gated in some environments — the + `npm view` / `curl | jq` Bash path is the primary reader; WebFetch is only for changelogs.) + +Then flag a HIDDEN FRAMEWORK MAJOR if either is true: + +- `peerDependencies` demand a different **major** of a framework we pin (react / react-dom + currently 18.3.1; node engine currently `>=22.18.0`). Canonical trap: **react-router 8** + requires `react/react-dom >=19.2.7` and imports the React-19-only `useOptimistic` hook, so + `react-router typegen` and `check:types` crash on React 18. A "7.x -> 8.x" line item is a + React 18->19 migration in disguise. +- `engines.node` exceeds our `>=22.18.0` (RR8's @react-router/dev needs `>=22.22`). + +If it is a hidden framework major, STOP: mark `viable: false`, blocker = +`"framework-major migration (peer )"`, and point to the migration epic (React 19 = +`plane-1ym`) instead of attempting it. Do not migrate the framework inside a bump validation. + +## Step 2 — For CVE-driven bumps, pick the version that clears ALL advisories + +When the reason for the bump is a security gate (trivy/grype fixable HIGH/CRITICAL), choose +the **lowest fixed version that clears every open advisory for that package**, and **prefer +staying within the current major when a same-major fix exists** (e.g. react-router 7.18.1 +rather than jumping to 8.x). Cross-check the package's advisories (GHSA IDs) against the +chosen version; a partial fix that leaves one advisory open does not clear the gate. + +## Step 3 — Run the validation loop (this is the proof; the registry read is only the screen) + +1. Edit the pin in the correct file (catalog / override / package.json). +2. `pnpm install` — regenerates `pnpm-lock.yaml`. Watch for `ERR_PNPM_LOCKFILE_CONFIG_MISMATCH` + (overrides serialization skew) and for a transitive dep splitting into two versions + (prosemirror-model 1.25.3 vs 1.25.11 silently broke `@plane/editor` on every regen until it + was pinned). A lockfile split of a shared lib is a blocker — pin it in pnpm.overrides. +3. `pnpm turbo run check:types` — expected green baseline is **28/28**. +4. `pnpm turbo run build` — expected green baseline is **16/16**. +5. `pnpm turbo run check:lint` — a bump can break lint INDIRECTLY: axios 1.18 re-exposed + `create` / `isCancel` / `CancelToken` as named exports, tripping oxlint + `import/no-named-as-default-member`, which then breaks the per-package `--max-warnings` + ratchet (e.g. `packages/services` is `--max-warnings=7`; web=11957, admin=759, space=676, + editor=416, ...). Any package that exceeds its ratchet is a blocker. + +**Turbo cache caveat:** turbo can MASK a latent failure — a green cache hit from `main` can +survive until a lockfile change busts it. A `pnpm install` that changed the lockfile normally +busts the affected hashes, but if in doubt confirm the loop actually re-executed (a +`>>> FULL TURBO` / all-cache-hit run is a warning sign), or re-run the failing task with +`--force`. Never trust a verdict that came entirely from cache hits. + +## Guardrails (hard) + +- NEVER commit, push, merge, or enable auto-merge. You produce a verdict; a human/parent acts. +- NEVER weaken a gate to make a bump pass — do not raise a `--max-warnings` ratchet, add a + `.trivyignore` / `allow-ghsas` entry, or soften the trivy severity. If clearing the advisory + legitimately requires a suppression (e.g. an unreachable RSC-mode CSRF), say so and hand it + to the human; do not apply it yourself.
