Lean, list-driven body that assumes Claude's competence — it does not explain what SERPs, backlinks, or Core Web Vitals are; nearly every token earns its place, with only minor editorial padding in the tool-paragraph.

Concrete, specific guidance throughout: named metrics (LCP, INP, CLS; domain rating; top 50 referring pages), a 7-step workflow, and a referenced fillable template rather than vague direction.

A clearly sequenced 7-step workflow (confirm competitors → pick angles → pull data → score → identify gaps → prioritize → write report) with a 'Failure patterns' guardrail section; no validation cap applies since this is analytical, not destructive/batch.

Body is an overview pointing to two real, one-level-deep reference files (competitive-audit-template.md, content-gap-method.md), both present on disk and clearly signaled via an inline link and a dedicated 'Reference files' section.

Lists multiple concrete actions and the five analysis angles explicitly: 'comparing the user's site to chosen competitors across SERP overlap, content depth, backlink profiles, technical posture, and brand presence.'

Explicitly answers both what ('Run a competitive SEO analysis...') and when ('Use this skill whenever the user wants to analyze competitors, find content gaps...'), with a clear 'Use this skill' trigger clause.

Strong coverage of natural phrasings a user would say, including 'content gap', 'backlink gap', 'why is X ranking', 'who is winning the SERP', and 'beat my competitor'.

Niche is clearly scoped to competitor comparison with distinctive triggers (e.g. 'why is X ranking', 'backlink gap') that are unlikely to fire for sibling SEO skills; written in third person, no voice penalty.
