skill-librarian

# Skill Librarian Apply an applicable Official Superpowers skill for process first; then invoke Librarian in the same task phase when triggered. ## Required trigger check Before planning or execution, invoke Librarian when: - specialized/unfamiliar guidance could prevent a wrong approach; - more than one workstream, deliverable, or domain may need composition; or - User explicitly asks for the Librarian or to find/select skills. Do not invoke it for simple general reasoning, direct edits without specialized guidance, or work covered by a native skill. Do not invoke it merely because a request mentions a tool or service; do not skip it because the task title sounds clear. ## Registry ```bash REGISTRY_ROOT="${AGENTIC_SKILL_REGISTRY_ROOT:-$HOME/.agents/agentic-skill-library}" ``` The registry CLI is the only discovery and loading runtime. Do not inspect or load catalog entries directly. ## Current-phase routing Read only the minimum reference set for the current phase. | Phase need | Reference to read | | --- | --- | | Every invoked phase: search, retry, select, and read | [control plane](references/control-plane.md) | | Every invoked phase: user-visible receipt | [decision trace](references/decision-trace.md) | | Safety metadata, action scope, or owner confirmation | [trust and safety](references/trust-and-safety.md) | | Multiple skills/phases or a Librarian subagent | [composition](references/composition.md) | | Admit a reviewed external source | [source intake](references/source-intake.md) | | Pressure-test routing or release this contract | [evaluation](references/evaluation.md) | ## Hard Rules - Never load the entire catalog or dump the whole discovery index. - Do not execute bundled scripts automatically. - Do not grant credentials or broad permissions to a selected skill. - Never bypass quarantine, path, symlink, or hash failures. - Keep official Superpowers unmodified and use it only for process guidance. - Do not add a runtime hook, MCP integration, or automatic router; this remains an on-demand skill contract.
