Lists multiple specific concrete actions: 'format-controlled research reports', 'evidence tracking', 'citations', and 'iterative review'. These are distinct, actionable capabilities.

Clearly answers both what (generate format-controlled reports with evidence tracking, citations, iterative review) AND when (explicit 'should be used when' clause listing specific use cases and differentiating from single deepresearch pass).

Excellent coverage of natural terms users would say: 'research report', 'literature review', 'market or industry analysis', 'competitive landscape', 'policy or technical brief', 'report template', 'section formatting'. These are terms users naturally use when requesting such work.

Clear niche with distinct triggers around structured research output. The explicit mention of 'strict report template and section formatting that a single deepresearch pass cannot reliably enforce' distinguishes it from simpler research skills.

The content is lean and efficient, assuming Claude's competence throughout. No unnecessary explanations of basic concepts; every section provides actionable guidance without padding.

Provides concrete, executable guidance with specific file structures, implementation patterns for Task tool usage, exact checklist items, and clear table column requirements. The workflow is copy-paste ready.

Excellent multi-step sequencing with explicit checkpoints (9 numbered steps with progress checklist). Includes validation steps (Step 8 verification), feedback loops (Step 9 iteration), and clear dependencies between steps.

Well-structured overview with clear one-level-deep references to 5 supporting files. Reference table clearly signals when to load each file. Content appropriately split between main skill and reference materials.
