Review findings

I'll start by exploring the repository structure and the files involved in the review findings.Now I have enough context. Let me check the Node version and run the baseline tests before making changes.Baseline confirmed: 646 pass / 1 pre-existing unrelated failure (mongodb manifest). Now let me apply the fixes, starting with librarySpec.ts.Now libraryArtifact.ts — rename re-export, add FILL_DEVIATIONS, guard the fallback layout, add uniqueness validation, and use a locale-independent sort.Now the tests — add duplicate-name, missing-layout, unknown-typography coverage, the fill-deviation record, and enforce locale-independent entry order.Now add the CI-runnable validator test (High finding) that runs Penpot's own schema validator when a checkout is configured.Now fix the Clojure validator (required argument + guaranteed close).Now update the asset README to record the fill deviation and the CI-runnable validator test.Now add the missing skills/penpot/SKILL.md so the directory is a real, loadable skill.Now update the repo README skill count to match the new skill directory.Now rebuild the committed artifact from the updated spec and run the gates.All tests pass except the same pre-existing unrelated failure. Let me verify no stale references to the renamed type and confirm the artifact actually changed.Let me review the final diff for the source changes to make sure everything is coherent.Let me confirm the rebuilt artifact differs only where intended (Button radius, and any ordering).All gates re-run: npm test = 650 pass / 1 pre-existing unrelated failure / 1 opt-in skip; the new library-artifact tests all pass and the rebuilt archive differs only in the Button's radius.

Review Findings — 206

Summary

Gates run: build — no build script or tsc exists in package.json (TypeScript runs via Node 22's type-stripping in node --test), so there is no build gate; lint — no ESLint/Biome/tsconfig or lint script is configured, so there is no lint gate; test — npm test gives 646 pass / 1 fail, and the single failure (root package.json manifest: … mongodb is declared, #647) is pre-existing and unrelated (the diff does not touch package.json, which already omits extensions/mongodb/index.ts on main). All 11 new libraryArtifact tests pass, and rebuilding the archive twice to /tmp produced byte-identical output equal to the committed .penpot. The change is well documented and its format/deviations are honestly recorded, but the deliverable's core acceptance criterion — that the artifact actually re-imports into Penpot — remains unverified, and the verification that does exist is largely self-referential.

Remediation pass (stage 3): Fixed the High finding by adding extensions/penpot/src/libraryArtifactValidation.test.ts, which runs the independent Clojure validator against the committed artifact when PENPOT_SOURCE_DIR points at a Penpot 2.17 checkout (skips otherwise, so the default suite stays offline). Fixed four Mediums (added skills/penpot/SKILL.md and updated the repo skill count; duplicate entry-path detection; locale-independent shape ordering; Button pill radius + recorded FILL_DEVIATIONS). Fixed four Lows (missing-layout now throws; validator closes the ZIP and requires its path argument; FontSubstitution renamed to RecordedFontSubstitution; added the unknown-typography failure test). Left the Critical finding (requires a live instance/token) and the Low commit-message finding (commit already made; the standard-vs-history conflict is ambiguous and out of scope) unresolved.

Critical

skills/penpot/assets/README.md:157 — The acceptance criterion "prove it re-imports" is not met: the .penpot artifact has never been through Penpot's importer (no PENPOT_URL/PENPOT_TOKEN in the implement environment), so its usability by penpot_import_library / penpot_link_library is an assumption backed only by an offline schema check. If a schema-valid but server-rejected archive ships, every downstream project's import fails. Suggested fix: run the three-step live checklist already written in this README ("Not yet verified": import into a throwaway project → open in the UI → link to a consumer and confirm components are reachable) on a token-bearing instance and record the result; if no token can be provisioned before merge, keep the artifact clearly marked provisional and obtain explicit owner sign-off that the issue is not "done" until the round trip is recorded.

High

extensions/penpot/src/libraryArtifact.test.ts:371 — The verification is self-referential: "the committed artifact is exactly what the spec rebuilds" regenerates the archive with the same buildLibraryEntries that produced it and compares entries, so any wrong format assumption survives npm test; the only independent check (scripts/validate-library-artifact.clj) needs an external Penpot 2.17 checkout that is not present and is not part of CI, and the server is never exercised. Suggested fix: add a CI-runnable acceptance test that feeds the committed archive through the import path against the existing Penpot stub (extensions/penpot/scripts/live-write-stub.mjs) and asserts the server accepts it, or commit the validator's raw output as a checked-in fixture so the claim is reproducible without a live instance.

Medium

skills/penpot/assets/README.md:1 — This change adds skills/penpot/ but no skills/penpot/SKILL.md, while every other directory under skills/ is a real skill and the repo layout documents skills/ # 14 skills, each a dir with SKILL.md (README.md:136). pi's loader (dist/core/skills.js) silently ignores skills/penpot/ (no SKILL.md, and nested root .md files are skipped), so the artifact lives in a pseudo-skill directory and the layout doc is now inaccurate. Suggested fix: add skills/penpot/SKILL.md (already listed as a deliverable in docs/PENPOT_SKILL_IMPLEMENTATION_PLAN.md:31) or relocate the artifact to extensions/penpot/assets/ and update DEFAULT_EXPORT_DIR in extensions/penpot/src/tools/exportLibrary.ts:79 plus README.md:136.
extensions/penpot/src/libraryArtifact.ts:426 — ShapeNode.name is documented as "names must be unique per component" because shape ids are derived from ${path}/${child.name}, but nothing enforces it: two same-named siblings silently produce the same id, the same ZIP entry path, and a corrupt archive (the test's Map would also collapse them). Suggested fix: after building, assert the entry paths and shape ids are unique (e.g. throw listing the duplicate path) before returning entries, and add a test for duplicate sibling names.
extensions/penpot/src/libraryArtifact.ts:616 — String(a.id).localeCompare(String(b.id)) is locale-sensitive by specification, so the entry order — and therefore the archive bytes — is not guaranteed across machines/locales, contradicting the "byte-identical" / "deterministic" guarantee in librarySpec.ts, findings.md and README.md. It happens to be stable for the current id set, but the guarantee is not enforced. Suggested fix: sort with a locale-independent comparator (a.id < b.id ? -1 : a.id > b.id ? 1 : 0) and, if the byte-identical claim matters, add a test hashing the built ZIP.
extensions/penpot/src/librarySpec.ts:241 — The Button sets radius: 12, but the cited source (web/DESIGN.md §5.1) defines the default (gold CTA) button as rounded-full, and the primary CTA uses a gold gradient (from-flip7-gold to-flip7-gold-dark) that the artifact flattens to a solid flip7-gold fill. The spec comment calls this set "the web/DESIGN.md §5 recipes", so the render diverges from the documented recipe. Suggested fix: use radius: "pill" for the Button and either represent the gradient (Penpot supports linear fills) or record the flattening alongside the font substitutions as a deliberate deviation.

Low

AGENTS.md:26 — The commit subject is 206: Author and commit the component library artifact under skills/penpot/assets, but the standard requires issue-<N>: <summary> (e.g. issue-206: …); the branch slug is also truncated mid-word (…artifact-u, AGENTS.md:23). Note repo history consistently uses the bare <N>: form, so this may be a stale standard rather than a mistake — reconcile either the standard or the message before the PR title is set. Suggested fix: use issue-206: … (matching AGENTS.md) or correct AGENTS.md to document the <N>: form actually practised.
extensions/penpot/src/libraryArtifact.ts:301 — The placeChildren fallback for a node with no layout stacks children at y + index * child.height at the parent's x, ignoring gaps, padding and the parent's position; it is never exercised by the current spec (every component frame sets layout), so it is untested and could silently produce wrong geometry if a future spec omits layout. Suggested fix: either throw for a frame that has children but no layout, or document the heuristic and add a unit test covering it.
extensions/penpot/scripts/validate-library-artifact.clj:44 — (def zf (ZipFile. (File. artifact-path))) is never closed (resource leak), and the default artifact-path (:39) is relative to the process CWD, which the documented usage sets to the Penpot common directory, so the no-argument default cannot resolve. Suggested fix: wrap access in with-open/try-finally and default to an absolute path or require the argument explicitly.
extensions/penpot/src/librarySpec.ts:35 — FontSubstitution is redeclared here with fields {requested, used, reason}, while changeset.ts already exports a FontSubstitution with {requestedFamily, usedFamily, reason}; the two shapes sharing a name is a readability/collision hazard for callers importing both. Suggested fix: rename one (e.g. RecordedFontSubstitution) or extend the existing type.
extensions/penpot/src/libraryArtifact.test.ts:403 — Only the unknown-colour failure path is tested (references colour "not-a-token"); typographyStyle throws for an unknown typography name (libraryArtifact.ts:410) but that branch has no coverage. Suggested fix: add a second assert.throws case with a text node whose typography is not in the scale, asserting /references typography "…"/.
