# Shared Skills Index

Single source of truth for skills delivered to both Claude Code (`~/.claude/skills/`) and Copilot CLI (`~/.copilot/skills/`) by the installer.

**Total:** 228 skills (67 core + 161 external). Auto-generated by `scripts/gen-skills-index.mjs`  -  do not edit by hand.

## Directory layout

- **`core/`**  -  67 `multi-agent*` orchestration skills that are pipeline-critical. Edits here are core-code changes.
- **`external/`**  -  161 iOS / Android / generic skills that ship into the stack plugins. Each names its origin in `metadata.source`: `multi-agent-pipeline` when written here, or the upstream and license a `NOTICE-*.md` in this directory covers.
- Install destinations (ADR-0009): Claude Code gets NO local copy of `external/` - it loads those skills from the `multi-agent-plugins` marketplace, namespaced (`ai-<stack>-toolkit:<name>`); only the two compliance catalogs from `core/` land in `~/.claude/skills/`. Copilot CLI and Codex CLI receive a flat copy filtered to the enabled stacks. `external/` remains the single authoring source that `build-stack-plugins.mjs` publishes from.

Source layout is logical grouping only  -  skill discovery at runtime is unchanged.
