Move the skill to .agents/skills/tttk-authoring and point gen:skill-reference at it. Activate it by symlinking ~/.agents/skills/tttk-authoring to the in-repo copy.
Extend the reference drift guard to cover the skill copy now that it is versioned, and document activation in docs/development.md.
Add D002 (malformed attribute blocks), R004 (skipped declare rows), and V001-V005 (CSV data files). CSV checks run once per referenced file and also cover inline spark-table bodies.
Generate docs/reference.md from the known.ts catalog via npm run gen:reference, and add drift guards asserting the catalog matches the customElement call sites and the committed reference.
