Init Agentic Skills

Init Agentic Skills

Invoke as $init-agentic-skills.

Initialize this agentic-skills checkout on the current machine by installing global core skills for both Claude and Codex. Active installs are repo-managed directories that expose the canonical SKILL.md and exclude archive/; copied managed launchers resolve this checkout through .agentic-skills-managed provenance. Pinned installs intentionally point at archive/<version>. Keep domain packs project-local; use $pack from the target project when packs are needed.

Workflow

1. Parse $ARGUMENTS:
   • No args, init, refresh, or sync: run scripts/init-agentic-skills.sh, then run the first-run setup prompts in step 6 when the drift preferences are still unset.
   • status: run scripts/init-agentic-skills.sh status, then report the local checkout commit, remote URL, and whether GitHub freshness is enabled by ~/.agentic-skills/preferences.json at sync.github_freshness_check.
   • doctor: run scripts/init-agentic-skills.sh doctor to report global skill-install drift (read-only). It compares installed ~/.claude/skills and ~/.codex/skills copies against canonical global/<tool>/<skill> via the .agentic-skills-managed marker's source_sha. Report stale skills with the fix $init-agentic-skills update, unknown skills as needing a re-init to enable tracking, and pinned skills as frozen.
   • update or latest: run scripts/init-agentic-skills.sh update only after confirming the user wants to check GitHub, fast-forward the local checkout, and rerun init.sh. This re-copy is the global "refresh" — it rewrites markers with current source_version/source_sha, clearing drift.
   • --uninstall, uninstall, or remove: run scripts/init-agentic-skills.sh --uninstall only after confirming the user wants repo-managed global installs removed.
   • help, --help, or -h: run scripts/init-agentic-skills.sh --help.
2. Report the initializer command, the Claude and Codex skill directories, installed/skipped counts, and warnings about non-repo-managed collisions.
3. Explain pack access separately:
   • Do not install packs/* globally.
   • In the project that needs domain workflows, run $pack for guided setup or $pack install <pack-or-skill> for an explicit pack or individual pack skill.
   • If a project already has .agents/project.json, use $pack refresh after this global initialization to recreate local pack skill roots.
4. If the active session still cannot see a newly installed skill, tell the user to start a fresh Claude Code or Codex session.
5. For update / latest mode:
   • Confirm before running commands that fetch, pull, or reinstall.
   • Fetch GitHub freshness, compare the local checkout to origin/HEAD, and update only with a fast-forward-only operation such as git pull --ff-only or an equivalent git fetch + git merge --ff-only.
   • If the update cannot fast-forward cleanly, stop and report the exact reason without rebasing, merging, stashing, or force-resetting.
   • After a successful fast-forward, rerun init.sh.
   • Warn that a fresh Claude Code or Codex session may be needed to see refreshed skill instructions.
6. First-run drift preferences (init / clone setup):
   • Default policy is track-latest (installed skills follow canonical; drift is observable). The two prompts below are opt-in and off by default, so the explicit-control default stays out of the box.
   • Only prompt when the preference keys are still unset. Check with scripts/init-agentic-skills.sh show-prefs; skip silently when both are already set.
   • Ask (a): "Enable a session-start hook that warns when tracked skills are behind canonical?" Default no.
     • If yes: run scripts/init-agentic-skills.sh hook enable (registers a SessionStart hook in ~/.claude/settings.json invoking scripts/skill-drift-hook.sh and sets skills.session_start_hook=true).
     • If no: run scripts/init-agentic-skills.sh set-pref session_start_hook false.
   • Ask (b): "Auto-refresh latest skills on session start (instead of just warning)?" Default no.
     • Run scripts/init-agentic-skills.sh set-pref auto_refresh <true|false> with the answer. Auto-refresh only takes effect when the hook is enabled.
   • To disable later: decline the prompt, run scripts/init-agentic-skills.sh set-pref session_start_hook false, or run scripts/init-agentic-skills.sh hook disable to remove the settings entry.

Constraints

• Delegate global initialization to scripts/init-agentic-skills.sh; do not recreate install logic by hand.
• Do not overwrite real directories or files under ~/.claude/skills, ~/.codex/skills, .claude/skills, or .codex/skills.
• Treat packs as project-local capabilities managed by scripts/pack.sh through $pack.
• Stop and report exact errors if the launcher cannot resolve the repository root or if root init.sh fails.
• Do not install packs/* globally in any mode.
