Summary

• Skill bodies already use Corbits tool and director names, so remove the GaaS/Claude tool table, the slash-name mapping, and the per-skill GaaS notes from native-integration (about 1,660 words down to about 1,150).
• Keep the Corbits-only rules: test runner, fleet spawn and plan gate, Linear claim-first (duplicate paragraph merged), non-git folders, tracker-agnostic issues, GitHub review posting.
• Convert the typescript skill tap examples to bun:test, since the mapping note that covered them is gone.

Verification

• bun run check green (7,870 tests).
• No GaaS or Claude tool names remain in the skills except one intentional create-issue line.
