Release Skill

Pre-launch checklist (run before tagging)

The pnpm changeset workflow handles versioning, but the human-judgment gates below decide whether the release is ready. Run all of these:

Code quality

• pnpm lint && pnpm typecheck && pnpm test — green
• pnpm coverage — coverage hasn't regressed below the gate (89.66% statements, 93.26% functions per CLAUDE.md)
• No TODO / FIXME / XXX comments in production source added in this release that should have been resolved
• No console.log debugging statements in production code
• All @deprecated markers added in this release have a clear replacement and migration path (see deprecation-and-migration skill)

Security

• pnpm audit shows no critical/high vulnerabilities (or each is documented + mitigated)
• No new secrets, env vars, or credentials added without .env.example placeholder + docs
• CodeQL alerts at 0 high/critical (see security-scanning skill)
• gh api repos/{owner}/{repo}/dependabot/alerts?state=open returns clean

Documentation

• CHANGELOG entry exists for every public-API change (changesets handles this if pnpm changeset was run)
• Migration recipe in changeset for any breaking change (typed-only or runtime)
• inject-governance.ts regen ran cleanly (CLAUDE.md skill table, AGENTS.md, marketplace.json all in sync)
• No stale @deprecated references in docs/

Pipeline health

• Last 5 release runs on main succeeded (gh run list --workflow=Release --limit 5)
• No release PR currently open (gh pr list --search "version packages") — if one IS open, merge it FIRST (a stale version PR is how npm gets ahead of main); see "Avoid the publish race" below
• npm view nexus-agents version matches packages/nexus-agents/package.json — the Detect npm-ahead version skew step in release.yml also enforces this, but check before tagging
• No changeset debt — every recent shippable-source PR shipped its own changeset (the Changeset Presence CI gate enforces this going forward)

Avoid the publish race

If you're merging a release PR while other PRs add changesets, you'll trigger the version-skip race documented in release-changeset-race.md. To avoid:

1. Hold non-trivial PR merges while a release PR is open
2. After merging the release PR, verify within 5 minutes: npm view nexus-agents version should match packages/nexus-agents/package.json
3. If it doesn't, the workflow's force-publish fallback (#2383) should kick in on the next push. If still stuck, see the runbook.

Pre-Release Checks

# Verify all gates pass
pnpm lint && pnpm typecheck && pnpm test

# Check fitness score (must be >= 90)
nexus-agents fitness-audit --format=json

Release Workflow (Changesets)

Releases are automated via changesets + GitHub Actions:

1. Add a changeset during development:

   pnpm changeset
   

2. Merge PR to main — the Release workflow will:

   • Create a "Version Packages" PR (bumps version, updates CHANGELOG.md)
   • When that PR merges, publish to npm via OIDC trusted publishing
   • Create a GitHub Release with auto-generated notes

3. No tokens required — npm authentication uses OIDC (see id-token: write permission in .github/workflows/release.yml). The trusted publisher is configured on npmjs.com to accept publishes from this repo's release.yml.

   IMPORTANT: npm trusted publisher config must match workflow filename. The npmjs.com package settings specify the exact workflow file (release.yml), repository (nexus-substrate/nexus-agents), and environment. If you rename the workflow file, update the npm trusted publisher config to match or publishing will fail with OIDC token rejection.

Manual Publish (emergency only)

# Manual publish via the same release workflow (uses OIDC, no tokens needed)
gh workflow run release.yml

# Or with dry run:
gh workflow run release.yml -f dry_run=true

Rollback (if needed)

npm unpublish nexus-agents@<version>  # Within 72 hours
git tag -d v<version> && git push --delete origin v<version>

Release CLI Commands

The project also has built-in release automation:

nexus-agents release-notes      # Generate release notes
nexus-agents release-validate   # Validate release readiness
nexus-agents release-announce   # Announce release

Anti-rationalization — Release

Red flags

• Release tagged with failing CI on main
• pnpm audit shows critical/high vulnerabilities
• CHANGELOG entry missing for a public-API change
• npm view nexus-agents version doesn't match package.json after release-PR merge (publish race — see release-changeset-race.md)
• Release PR merged while other changeset-adding PRs are open
