Conciseness

The body is mostly lean — short sections, runnable commands, no concept explanations Claude already knows — but there is minor redundancy: 'Core Capabilities' restates the workflows that follow, and 'Regression Loop' overlaps with 'Rollout Strategy', so a little could be trimmed.

Actionability

Both scripts get concrete, verified, copy-paste-ready command examples (flags match the actual argparse definitions), and the test-case schema fields are named explicitly. The gap is that no full example test-case JSON or sample output is shown, keeping it just short of fully covering the common cases.

Workflow Clarity

The regression loop and rollout strategy are clearly sequenced with explicit validation gates ('Promote only if score and safety constraints improve', 'violation count stays at zero'), a pre-promotion checklist, and an error feedback loop ('feed new failure cases back into test suite') — matching the top anchor.

Progressive Disclosure

The References section clearly signals each of the three real reference files with one-line content descriptions at one level of depth, and scripts are properly external. However, the body links a README.md that does not exist in the bundle, a minor navigation gap that keeps it below the top anchor.

Specificity

The description enumerates multiple concrete capabilities — 'A/B prompt evaluation against structured test cases', 'immutable prompt version history with diffs', named template categories (ad copy, email campaigns, social posts, landing pages, SEO meta), and governance specifics (claim discipline, disclosure rules, human-review gates) — giving comprehensive, non-generic coverage.

Completeness

It explicitly answers both what ('Turns marketing prompts into tested, versioned production assets: A/B prompt evaluation... immutable prompt version history... templates... governance playbook') and when ('Use when a marketing team relies on AI-generated content... or when the user mentions...') with concrete trigger phrases, matching the top anchor exactly.

Trigger Term Quality

Six natural, quoted user phrases ('prompt engineering', 'improve my prompts', 'prompt templates', 'prompt versioning', 'AI content workflow', 'AI governance for marketing') give good coverage, but common variations like 'prompt testing', 'A/B test my prompts', or 'evaluate prompts' are missing, so it falls just short of the comprehensive anchor.

Distinctiveness Conflict Risk

The marketing-team prompt-ops niche is mostly distinct with marketing-flavored triggers, but the bare 'prompt engineering' trigger would collide with any general prompt-engineering or prompt-writing skill, leaving minor overlap risk.
