The body is mostly efficient domain methodology, but repeated syllabus citations ('CTAL-TM v3.0 §3.1.1', 'after Sonntag & Schmidt-Rathjens 2005 and Erpenbeck & von Rosenstiel 2017') and time-stamped references ('(2024)', '2026-06-10') add tokens that could be tightened.

Provides a concrete 0–3 proficiency scale with per-level evidence rules, a copy-paste markdown matrix template with footnotes, and a gap-class table with signals and typical responses — guidance is specific and ready to use.

A clear 6-step sequence (Step 1–6) with an explicit halt checkpoint ('Halt with MISSING_REQUIRED_SKILLS_CONTEXT') and the load-bearing evidence rule as a validation gate, plus an anti-patterns checklist for complex-process guardrails.

The full 5-person worked example is appropriately split to a real, clearly-signaled one-level-deep reference (references/skill-matrix-example.md), keeping the methodology lean in SKILL.md.

Lists multiple concrete actions — 'produces a QA team skill matrix', 'each cell backed by observable evidence', 'derives a gap analysis comparing the matrix against the team's required testing skills' — matching the 'lists multiple specific concrete actions' anchor.

Explicitly answers both what ('produces a QA team skill matrix … then derives a gap analysis') and when ('Use when a QA manager needs to know what the team can do today versus what its projects demand').

Natural domain terms a QA manager would actually say are well covered: 'skill matrix', 'gap analysis', 'what the team can do today versus what its projects demand', 'training, hiring, or work allocation'.

Negation clauses ('not a point-in-time score of external candidates, not the downstream prioritization … not one new hire's ramp plan') carve a clear niche distinct from the named sibling skills.
