Update Packages

Operation Mode

Identify the operation mode before running any update command:

• Use Advisory mode to analyze, report, and propose changes only. Do not create a branch.
• Use Execution mode to apply version changes. Create a fresh update branch before the first package edit.

References

Use these references during execution:

• references/package-groups.md — package groups that must be updated together
• references/feature-adoption-tiers.md — T0-T3 adoption rubric
• references/report-formats.md — release report and "What's New" output formats
• references/testing-matrix.md — required tests by update type
• references/runtime-checklists.md — Bun and Playwright update checklists

Step 0: Prepare Session (Execution mode only)

Update skills and create a dedicated branch before touching packages.

# Update all skills from skills-lock.json (reads sources + skill names from lock)
bun run .agents/skills/update-packages/references/skills-update-local.ts

# Dry run to see what would be executed
bun run .agents/skills/update-packages/references/skills-update-local.ts --dry-run

# Create a fresh branch
git checkout -b chore/update-packages-$(date +%y%m%d-%H%M)

Apply these rules:

• Update skills first.
• Create a new update branch for execution work.
• Reuse no previous update branch.
• Place all update commits on the execution branch.

Update Strategy

Per Package Group Flow

Read references/package-groups.md. Execute steps 1-4 for each group before moving to the next group.

Step 1 — Identify versions + release notes

Run all three reports:

bun run .agents/skills/update-packages/references/check-outdated.ts
bun run .agents/skills/update-packages/references/check-outdated.ts --changelog
bun run .agents/skills/update-packages/references/report.ts --json

Use generated JSON files as session data:

Handle stale report files before analysis:

• Regenerate all three reports at session start.
• Delete old report files first if they contain data from a prior run or branch.
• Treat saved JSON files as disposable local artifacts. Do not commit them.

Handle catalog packages in one place:

• Find catalog versions in root package.json under catalog and catalogs.
• Check latest versions manually (npm view <package> version) when needed.
• Respect the repository's Bun install policy in bunfig.toml, especially minimumReleaseAge and related excludes.
• Do not bypass Bun's age gate with flags like bun install --minimum-release-age 0 unless the user explicitly requests that override.
• If a desired version is blocked by minimumReleaseAge, choose the newest older compatible version that satisfies the policy and update the manifest to that version instead of forcing the install.
• Update catalog entries manually, then run plain bun install.

Step 2 — Update + Adopt features IN PARALLEL

Delegate release-note research to a subagent/librarian when available. If delegation is unavailable, process package groups sequentially in the main agent with the same rubric.

Apply the T0-T3 rubric from references/feature-adoption-tiers.md.

Step 3 — Check + Fix

Run required tests from references/testing-matrix.md. Run bun run check at minimum. Fix failures using release-note context from outdated-changelog.json.

Step 4 — Commit the group

Use separate commits for version bumps and feature adoptions:

• chore: update <package> to vX.Y.Z — version bump only
• feat: adopt <package> vX.Y improvements (<feature list>) — config/code changes from new features

Release Notes Report

Generate the release report using references/report-formats.md. When using subagents, require each subagent to search for usages of changed/deprecated/new APIs. When running sequentially, perform the same search directly.

What's New Summary

Generate the "What's New" summary using references/report-formats.md. Use outdated-changelog.json as the primary source. Fetch missing release notes with a librarian only when needed.

Special Cases

Apply Bun and Playwright update checklists from references/runtime-checklists.md.

Testing Requirements

Use references/testing-matrix.md to choose required tests.

Guardrails

• Do not update packages with workspace:*.
• Do not skip @typescript/native-preview updates.
• Do not use bun outdated; use check-outdated.ts.
• Do not bypass Bun's minimumReleaseAge policy unless the user explicitly asks for it.
• If bun install fails due to minimumReleaseAge, downgrade the requested package versions to the newest policy-compliant releases and retry with plain bun install.
• Run bun clean:packages then bun install if install fails.

Definition of Done

• Confirm check-outdated.ts shows no remaining direct dependency updates.
• Confirm bun run check passes.
• Confirm all tests required by references/testing-matrix.md pass.
