Summary

  • Pin maintainer Bun to 1.4.0 (packageManager, @types/bun, CI). Published engines.bun stays >=1.0.0.
  • test uses --isolate and includes scripts/upgrade-packages. Coverage stays on ./src only.
  • Add the upgrade-packages gatherer (bun pm diff) plus an agents skill.
  • Add dedupe:check to check and CI.

Test plan

  • bun run test passes
  • bun run dedupe:check passes
  • CI setup uses 1.4.0

Summary by CodeRabbit

  • New Features

    • Added a package-upgrade workflow that gathers dependency versions, security advisories, usage data, release notes, and upgrade differences into an evidence report.
    • Added automated analysis for upgrade risks, version compatibility, duplicate packages, and high-risk dependencies.
    • Added package-difference summaries with prioritized file changes and release-note classifications.
  • Bug Fixes

    • Pinned project and CI environments to Bun 1.4.0.
    • Added CI checks to detect dependency duplication and block completion when issues are found.
  • Tests

    • Added coverage for version ranges, advisory results, dependency parsing, and upgrade-difference processing.
  • Documentation

    • Documented the package-upgrade workflow and evidence report format.

Keep published engines.bun at >=1.0.0. Add upgrade-packages evidence via bun pm diff, and fail check/CI when the lockfile is not deduped.

📝 Walkthrough

Walkthrough

The change adds an artifact-driven package-upgrade workflow. It gathers dependency, advisory, usage, outdated-package, and tarball-delta evidence. It adds tests, Bun 1.4.0 pinning, deduplication checks, CI gating, and workflow documentation.

Changes

Tooling and CI integration
package.json, .github/workflows/ci.yml, .github/actions/setup/action.yml, .github/CONTRIBUTING.md, lint-staged.config.js, knip.json, .oxfmtrc.json, scripts/upgrade-packages/.gitignore
Adds evidence and deduplication scripts, isolated tests, CI deduplication gating, Bun 1.4.0 pinning, recursive Knip entries, and generated-artifact exclusions.
Upgrade workflow guidance
.agents/skills/upgrade-packages/SKILL.md, .agents/skills/upgrade-packages/REFERENCE.md
Documents the package-upgrade workflow, evidence artifact schema, citations, validation requirements, verdicts, and error handling.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 21164

This PR adds dependency-upgrade analysis while pinning Bun and isolating tests, but the current analysis can misclassify dependency advisories and omit required break-risk evidence, potentially allowing an unsafe upgrade to be accepted. Merge should wait for these bounded correctness issues to be fixed or explicitly accepted by the owner.

Scope knip entries to the root workspace so src tests stay visible, ignore bun's dedupe builtin, and pin transitive tar to 7.5.22 so audit no longer blocks on GHSA-r292-9mhp-454m.

223-229: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Resolve the dead 0.x branch in bumpClass.

Lines 227 and 228 return the same expression, so the ca === 0 check has no effect. Either the intended 0.x rule was lost, or the branch should be deleted. For 0.x packages a minor bump is normally treated as breaking, and the skill uses bumpClass to rank risk. State the rule explicitly.

♻️ Option A — classify 0.x minor bumps as major
   if (la !== ca) return "major";
-  // 0.x: second digit is the minor
-  if (ca === 0) return lb !== cb ? "minor" : "patch";
+  // 0.x: a minor bump is breaking under semver's initial-development rule.
+  if (ca === 0) return lb !== cb ? "major" : "patch";
   return lb !== cb ? "minor" : "patch";
♻️ Option B — drop the branch
   if (la !== ca) return "major";
-  // 0.x: second digit is the minor
-  if (ca === 0) return lb !== cb ? "minor" : "patch";
   return lb !== cb ? "minor" : "patch";

Refetch when a cached payload fails to parse.

cachedParsed parses the cached text directly. If a cache file is truncated or was written under a different payload shape, parse throws on every run until the TTL expires. For bun pm diff the TTL is 7 days, so the affected package stays stuck at failedDelta.

♻️ Proposed change
   const cached = await readCache(key, maxAgeMs);
-  if (cached) return parse(cached);
+  if (cached) {
+    try {
+      return parse(cached);
+    } catch {
+      // Stale or corrupt cache entry — fall through and refetch.
+    }
+  }
   const raw = await fetchText();

Add a subprocess timeout.

Add timeoutMs to the options for run and runSoft. Pass it as timeout to Bun.spawn, with killSignal: "SIGKILL". Use the same timeout for bun pm diff, gh api, and bunx codemap.

In @.agents/skills/upgrade-packages/REFERENCE.md:
- Around line 66-67: Update the “Verdict a package” checklist to include
typeOnlySymbols, sites, callSites, deprecations, and peerEngine alongside
importedSymbols and the delta break-risk fields. Ensure Phase 3 break-risk
analysis is explicitly mandatory so type-only usage and peer/engine constraints
cannot be omitted.

In @.agents/skills/upgrade-packages/SKILL.md:
- Line 61: Update the adoption opportunities output requirements around the
usage verdict so each feature citation is backed by artifact evidence: map
features to detected symbols and file:line locations when usage exists, or omit
file:line when the artifact establishes that the package has no usage. Keep
adoption entries non-blocking and preserve the existing follow-up and why-adopt
fields.

In `@scripts/upgrade-packages/evidence.ts`:
- Around line 854-870: Update the installed-version map in the upgrade flow to
overlay each matching package’s resolved o.current value from parseBunOutdated
before calling ghsaSpotCheck, while retaining the existing package.json-derived
value when no outdated entry exists. Ensure advisoryFromGhsa and ghsaVerdict
receive resolved versions rather than range floors.
