Conciseness

Dense and assumes Claude's competence throughout — no elementary concept padding — but a few sections (axes table, output schema, common mistakes table) could be tightened slightly; mostly efficient with minor over-explanation.

Actionability

Provides fully executable guidance: exact exit-code contract (0/10/1), concrete grep patterns, fixed-schema YAML, specific promptfoo assertion types (is-json, regex, not-icontains), and pointer to a real template file.

Workflow Clarity

Mermaid flowchart sequences the work and includes an explicit validation checkpoint (run promptfoo, confirm all assertions pass before reporting ROI) with a feedback loop (fix assertion or underlying fix until all pass).

Progressive Disclosure

Overview body points to two real, one-level-deep reference files (pattern-catalog.md, promptfoo-template.yaml) via clear markdown links, with detail appropriately split out and easy navigation.

Specificity

Lists multiple concrete actions — auditing a skill for LLM-judgment steps, offloading to code, constraining output format, and emitting runnable promptfoo assertions — with comprehensive coverage and no vague filler.

Completeness

Explicitly answers both what (find nondeterministic steps and emit runnable assertions) and when ("Triggers for ..." with concrete trigger phrases), satisfying both halves concretely.

Trigger Term Quality

Provides natural trigger phrases users would actually say ("make this skill more deterministic", "audit a skill for determinism", "where can this skill be deterministic") plus the slash command, covering synonyms and variations.

Distinctiveness Conflict Risk

Occupies a clearly distinct niche (determinism auditing with promptfoo assertions) with specific trigger phrases unlikely to collide with general code-review or testing skills.
