- Add model: sonnet to SKILL.md frontmatter (Claude Code extension; correct
location per research — runtime config belongs in frontmatter, not META.md)
- Document model field in SKILL-TEMPLATE.md with factory §9 routing guidance
- Wire grill output explicitly to trigger description step (step 3 now references
agreed name/category/purpose from grill rather than drafting independently)
- Strengthen eval self-check: presence check → coverage check (trigger cases +
at least one output case required)
- Bump META.md to v1.2 (2026-05-26)
- Add three LESSONS.md entries: META-TEMPLATE comment retention, overlap check
scope (deployed dir not just repo), model field placement boundary
