Conciseness

The ~840-line body restates the TDD cycle four times ("TDD Mapping for Skills" table, "The Iron Law", "RED-GREEN-REFACTOR for Skills", "Skill Creation Checklist", "The Bottom Line"), explains concepts Claude already knows ("Skills are modular, self-contained packages..."), and has a broken "Discovery Workflow" numbered 1,3,4,5,6 plus two duplicate "### 4." headings. Matches anchor 2 (noticeably verbose, several padded/redundant sections); not 3 because the redundancy is pervasive rather than occasional.

Actionability

Provides concrete, executable guidance: a full SKILL.md template with YAML frontmatter, specific commands (`mkdir -p skills/<skill-name>`, `wc -w skills/path/SKILL.md`), checklists, and example user questions. Mostly executable per anchor 4; not 5 because the core testing methodology is delegated to a referenced external skill rather than shown, and some checklist items are unexecutable as written.

Workflow Clarity

"Skill Creation Process" Steps 1-6 are clearly sequenced with skip conditions, validation (Step 5), and iteration (Step 6), and the RED-GREEN-REFACTOR cycle supplies explicit feedback loops ("Re-test until bulletproof"). Not 5 because two competing workflow framings (the TDD cycle vs. the Step 1-6 process) coexist, and validation checkpoints are stated as unchecked checklist bullets rather than gated pass/fail steps.

Progressive Disclosure

No bundle files exist, yet the body references "persuasion-principles.md" and links an external graphviz conventions file — a dangling reference. Content is well-headered but monolithic: CSO details, flowchart rules, and anti-pattern reference material are inlined that the skill's own guidance says belongs in references files. Matches anchor 3 (some structure, content that should be separate is inline); not 2 because section headers do provide navigable structure.

Specificity

Explicitly lists several actions — "create a new skill (or update an existing skill)", "verifying skills work before deployment", "testing with subagents", "iterating until bulletproof" — though the opener "Guide for creating effective skills" is generic. Matches anchor 4 (several specific actions, minor gaps); not 3 because more than 1-2 actions are named, not 5 because the actions are process-level rather than fully concrete.

Completeness

Both answered explicitly: what ("applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization") and when ("Use when creating new skills, editing existing skills, or verifying skills work before deployment"). Trigger guidance is explicit, voice is third-person ("This command should be used when..."), matching anchor 5.

Trigger Term Quality

Good natural-term coverage: "creating new skills", "editing existing skills", "verifying skills", "TDD", "subagents", "rationalization". Missing common variations like "SKILL.md", "write a skill", or "skill authoring", so it falls short of anchor 5's comprehensive synonym/extension coverage.

Distinctiveness Conflict Risk

Occupies a clear niche (skill authoring/testing) with distinct trigger phrases; minor overlap risk only with closely related skills it itself references (e.g. skill-best-practices commands). Not 5 because the generic "creating effective skills" domain could collide with other skill-writing skills.
