Conciseness

The material is dense and original (TDD mapping, micro-testing protocol, form-matching guidance) rather than re-teaching known concepts, but there is systematic redundancy: "NEVER summarize the skill's process or workflow" appears in three sections, description-format rules are given twice (SKILL.md Structure and SDO section 1), and the REQUIRED BACKGROUND pointer is repeated. Not 4 because this repetition could be consolidated; not 2 because nothing pads with knowledge Claude already has.

Actionability

Provides executable commands (wc -w, render-graphs.js invocations), a concrete 5-step micro-test protocol with control conditions and rep counts, good/bad YAML and markdown examples, and a phased checklist. Not 5 because the core pressure-scenario methodology is deferred to testing-skills-with-subagents.md, which is not present in the bundle, leaving key steps unretrievable.

Workflow Clarity

The RED-GREEN-REFACTOR cycle is explicitly sequenced with validation at every phase: run baseline without the skill and document verbatim, re-run with the skill to verify compliance, then "Re-test until bulletproof" — a full feedback loop, reinforced by a phased creation checklist. Matches the top anchor (clear sequence, explicit validation, feedback loops, checklist).

Progressive Disclosure

Scored against the actual bundle: every locally referenced file — anthropic-best-practices.md, testing-skills-with-subagents.md, graphviz-conventions.dot, render-graphs.js, persuasion-principles.md — is missing (no references/, scripts/, or assets/ directories exist), so navigation to the heavy material resolves to nothing. Not 3 because the references are not merely unclearly signaled but broken; not 1 because the body itself is well-sectioned with only one-level references intended.

Specificity

Lists several specific actions — "creating new skills, editing existing skills, or verifying skills work before deployment" — covering the full skill lifecycle with only minor gaps. Not 5 because "verifying skills work" is generic and no capability beyond the three verbs is stated; not 3 because coverage exceeds the 1-2 action anchor.

Completeness

The description is entirely a "when" clause with no explicit "what" — it never states what the skill provides (TDD-based skill authoring methodology). Falls between anchor 2 (only 'when', no 'what') and anchor 4 (both present): the trigger verbs weakly imply the supported tasks, putting it noticeably above 2 but below 4.

Trigger Term Quality

Natural phrases a user would say ("creating new skills", "editing existing skills", "verifying skills") are present. Not 5 because common synonyms and concrete artifacts are missing ("writing skills", "authoring", "SKILL.md", "testing a skill", "deploy").

Distinctiveness Conflict Risk

The skill-authoring niche is distinct with clear triggers ("creating new skills", "editing existing skills"). Not 5 because it could overlap with sibling authoring/testing skills in the same ecosystem, which would trigger on similar phrasing.
