name: skill-source-citations description: Requires durable citations when authoring or researching Agent Skills—maintain references/sources.md per skill, link external research, and record provenance in PRs.

Skill source citations

Rule: Knowledge borrowed from docs, papers, other repos, or chat research must be saved as links in the skill tree—not only in conversation.

When to use

• Creating or editing any skills/{name}/SKILL.md
• Researching harness/MCP/marketplace patterns before writing a skill
• Reviewing a PR that adds procedural claims without sources

Per-skill file (required in skill_steward)

Maintain skills/{name}/references/sources.md:

# Sources

| Topic | URL | Used for |

Workflow (create or update skill)

1. Before writing — list URLs you will rely on in references/sources.md (can start sparse).
2. In SKILL.md — link to spec/docs inline where non-obvious; prefer references/ for long material.
3. After research — append new rows + changelog entry; never leave “we read X” only in chat.
4. In PR — one line in description: “Sources updated in references/sources.md.”
5. Validate — pnpm run validate warns if sources.md is missing.

What to cite

Do not cite ephemeral chat URLs or private tokens.

Cross-skill index

Guild-wide references: docs/STANDARDS.mdx, DESIGN_FAQ.mdx.
