Standardize on Claude Code's SKILL.md format as every skill's source of truth. skill.toml becomes an optional metadata layer for runtime, input schema, and versioning — never for the prompt body. - validate.py: require SKILL.md in every skill dir; when skill.toml also exists, cross-check name/description consistency to prevent drift - Add SKILL.md to the two custom-skill examples - Move the meeting-agenda prompt body out of skill.toml into SKILL.md - Rewrite skills/README.md to document the md-first, toml-as-metadata convention Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
