About

External Skill Fixture Builder

Use this skill when a third-party ecosystem pattern should be tested by skill-harness but should not become a live dependency.

Process

  • Choose the fixture lane by install posture, not by brand:
  • pure SKILL.md pack
  • plugin manifest
  • Cursor .mdc rules
  • Codex/Claude/Cursor subagents
  • MCP/tool config
  • generated record/replay skill
  • Beads or task-memory repo
  • multi-agent workspace layout
  • Use minimal synthetic fixtures when possible.
  • Use pinned external snapshots only when real structure matters and license/provenance allows it.
  • Keep fixtures out of global user directories and live install caches.
  • Make the fixture assert one behavior: parse, classify, trust recommendation, drift detection, render target, or installer opt-in.
  • Add a command or check that proves the fixture is exercised.

Follow-Up Adoption Question

Avoid

  • making fixtures large mirrors of public repos
  • using fixtures as a back door for third-party adoption
  • mixing fixture coverage with default installer behavior
  • storing credentials, real traces, browser recordings, or private task state in fixtures
