# Bootstrap (启动器) Runs once at session start. Part of Installer's `bootstrap/` sub-module (see ADR-0007). ## Procedure 1. **Verify Distributor** — confirm `meta/distributor/SKILL.md` carries `user-invocable: false` + `always_active: true`. If not, warn the user: routing is broken. 2. **Verify on-demand scope** — confirm all other meta skills (builder / installer / domain-entry) and every domain skill stay `user-invocable: true` (horizontal components stay `false`). They load on demand, not always. 3. **Verify INDEX.yaml** — list actual `domain/` + `meta/` SKILL.md files; compare against `meta/distributor/INDEX.yaml`. On drift, rebuild INDEX.yaml from frontmatter and report. 4. **Report** — print an installation-status summary; surface any mismatch before the session proceeds. ## Drift handling - Skill present on disk but missing in INDEX.yaml → add entry from its frontmatter. - Entry in INDEX.yaml but skill deleted → remove the entry. - Stale `risk_level` / `category` → overwrite from frontmatter. - Never silently proceed on drift; report and resolve first. ## Conflict resolution When a skill already exists at the target (same `name` in `~/.workbuddy/skills/`): 1. **Compare frontmatter** — check `name` + `description` values. - If identical: skip (no-op). - If different: compare the `source` field. 2. **Priority rules**: - If installed target has `agent_created: true` and MY_SKILL has `source:` (forked): preserve installed version.
