Update Metaswarm

Update metaswarm to the latest version, refresh component files, and re-detect project context.

Usage

/metaswarm-update-version

Steps

1. Check Current Version

• Read .metaswarm/project-profile.json and extract metaswarm_version
• If the file doesn't exist, stop and tell the user:

  No project profile found. Run /metaswarm-setup first to initialize metaswarm.

• Display the current version to the user

2. Fetch Latest Version

• Run npm view metaswarm version to get the latest published version
• Compare current vs. latest:
  • If current == latest: tell the user they're already up to date and stop
  • If current < latest: continue to the next step

3. Show What's New

• Run npx metaswarm@latest changelog --from <current-version> to show changes between versions
• If that fails, try npx metaswarm@latest changelog and filter entries after the current version
• Highlight any BREAKING CHANGES prominently if present
• Show a summary of new features, fixes, and new components

4. Update Files

• Run npx metaswarm@latest install to refresh all component files
• This uses skip-if-exists semantics — user customizations in CLAUDE.md, agents, etc. are preserved
• New files (new skills, commands, agents, guides) will be added
• Existing metaswarm-shipped files will be refreshed to latest versions

5. Re-detect Project Context

• Re-run project detection from the setup flow:
  • Language, framework, test runner, linter, formatter, package manager, type checker, CI, git hooks
• Compare new detection results against detection in the existing project profile
• If changes are detected (e.g., project switched from Jest to Vitest):
  • Show what changed
  • Ask user if they want to re-customize affected files (e.g., update coverage commands in CLAUDE.md)
  • If yes, apply the same customization logic from /metaswarm-setup

6. Update Project Profile

• Update .metaswarm/project-profile.json:
  • metaswarm_version → set to new version
  • updated_at → set to current ISO 8601 timestamp
  • detection → refresh if project context changed (preserve if unchanged)
• Preserve all other fields (installed_at, choices, commands, etc.)

7. Summary

• Print what was updated:
  • Version change (e.g., 0.6.0 → 0.7.0)
  • Number of files refreshed or added
  • Any new skills, commands, or agents that were added
  • Any project detection changes
• If there were breaking changes, remind the user to review them
• Suggest reviewing the changelog for new features to take advantage of
