Fix Frontmatter

Goal

Bring every SKILL.md under skills/ back into conformance with the frontmatter
contract that CI enforces, so scripts/validate-frontmatter.py passes.

When to use

After adding or editing any SKILL.md, or when CI's "SKILL.md frontmatter
validation" job fails.

Steps

1. Run python3 scripts/validate-frontmatter.py and read every reported issue.
2. For each flagged file, fix the frontmatter:
   • name: → kebab-case, starts with deepworkplan (e.g. deepworkplan-create)
   • version: → quoted SemVer ("2.8.0")
   • replace homepage: with documentation_url:
   • ensure --- delimiters and the required keys exist
3. Re-run the validator until it prints OK: all N SKILL.md file(s) validated.

Validation

python3 scripts/validate-frontmatter.py exits 0.

Notes

Never edit a version: number to make the check pass — fix only quoting or
format. The auto-release.yml bot owns version numbers (AGENTS.md §4). The
validator scans skills/ only; .agents/skills/* is not CI-gated but follows
the same style.
