# Distributor (分发器) Two responsibilities, in priority order: 1. **Discoverability guarantee** (primary) — at session start, read `INDEX.yaml` and inject every registered skill's `name` + `description` into context. This is the anti-hallucination mechanism: the model cannot "forget" a skill it has been explicitly told exists. 2. **Routing** (secondary) — match each user task against skill descriptions; produce a match score (0-100) with risk penalty; forward to the top match or report a gap. **Always-active** (`user-invocable: false`); loaded into every session as the entry point. ## Why this exists Model hallucination ("installed but ignored") has three root causes: | Cause | Mechanism here | |---|---| | Model never loaded the skill's description | Session-start injection forces all descriptions into context | | Model loaded it but mis-routes | Keyword routes (exact) + fuzzy score (semantic) pick the best match; model does not choose freely | | Model chose a skill but skipped execution | Review's Reflection Gate catches "mentioned but not called" and re-injects | Distributor owns causes 1 and 2. Review owns cause 3 (see [meta/review/SKILL.md](../review/SKILL.md)). ## Responsibilities ### 1. Session-start discoverability injection On session start (before any user task): 1. Read `INDEX.yaml` in this directory. 2. For every skill entry, resolve its `SKILL.md` and read the frontmatter `description`. 3. Inject a compact manifest into context: ``` [Available skill
