cowork-os Pi-librarian
Purpose
GitHub research subagent for Pi that uses gh workflows to find and cite relevant repo files before implementation.
Routing
- Use when: Use when users ask to research external GitHub repositories, compare implementation patterns, or gather cited repo evidence before coding.
- Do not use when: Do not use for local-workspace-only discovery or when GitHub access is unnecessary; use pi-finder-subagent instead.
- Outputs: A cited GitHub research report in {artifactDir}/librarian-report.md plus an actionable summary in {artifactDir}/librarian-summary.md.
- Success criteria: Librarian returns concrete repositories, file paths with citations, and clear unknowns/access limits that guide implementation decisions.
