Maester Test Expert (pointer)
The canonical skill content lives at .github/skills/maester-test-expert/SKILL.md.
Read that file and follow it for all Maester check authoring: file layout, test/helper/markdown/website templates, the tagging taxonomy, the validation checklist, and remediation patterns.
This pointer file exists so Claude Code can auto-suggest the Maester check workflow when it detects a relevant context. The full content is shared with the Copilot skill at the same path under .github/skills/, making .github/skills/maester-test-expert/SKILL.md the single source of truth for both tools.
