Conciseness

The body is lean with no explanation of concepts Claude already knows and every section carries procedure, but the preserve-exact-failure theme recurs ~5 times ("Preserve each structured worker result and its exact failure reason", "relay the exact reason", "Relay worker results without interpretation"), leaving minor trim opportunities — anchor 4 rather than 5.

Actionability

Concrete guidance dominates: exact scratch path ".tmp/scratch/plans/{skill-name}-research-plan.md", structured result fields "STATUS", "ARTIFACTS", "SOURCES", "GAPS", "WARNINGS", a filled-in final report template, and anchor-linked handoffs. Minor gaps remain: "Run the package-appropriate existing validator" names no command, and "Use the host's available worker mechanism" is deliberately abstract — anchor 4, not quite copy-paste-ready 5.

Workflow Clarity

A clear three-stage sequence with an explicit overview diagram, three validation gates with checklists ("Gate 2: Source and Citation Review" enumerates per-category confirmations), feedback loops ("Return a category with unsupported claims to the same worker with the exact claims, not a summary"; "revalidate their citations before integration"), and a dedicated Failure Recovery section — matches anchor 5.

Progressive Disclosure

The body is an overview; worker handoff details are offloaded to references/agent-prompts.md via anchor links that resolve to real headings (## Categorization Handoff, ## Research Handoff, ## Integration Handoff), plus mcp-tools.md and gaps-analysis.md in a References section — all one level deep, all files verified to exist, matching the anchor-5 structure.

Specificity

"Builds a skill from official documentation through categorized research, citation review, integration, and final validation" lists several specific actions with comprehensive pipeline coverage, but the actions are process-stage labels ('citation review', 'integration') rather than fully concrete operations, so it sits between the 4 and 5 anchors — closer to 4.

Completeness

The 'what' is explicit ("Builds a skill from official documentation through categorized research, citation review, integration, and final validation") and the 'when' is explicit with concrete trigger phrases ("Use when researching a tool or library before creating a skill, when 'research for skill' or 'create comprehensive skill' is requested..."), matching the anchor-5 example.

Trigger Term Quality

Natural phrases users would say are present — "researching a tool or library", "research for skill", "create comprehensive skill", "multi-source documentation gathering" — but common variants like "build a skill" or "document a library" are missing, matching 'good keyword coverage; a few natural terms missing'.

Distinctiveness Conflict Risk

The skill-creation niche with distinct triggers like "research for skill" is mostly distinct, but the broader trigger "when extensive multi-source documentation gathering is needed" could overlap with generic research skills — minor overlap risk, matching anchor 4.
