Conciseness

The body is lean and assumes SEO competence — the gap matrix, banding table, failure patterns, and output spec all earn their tokens with no generic SEO explanations. Minor trimmable redundancy remains: the scoring weights appear both in the dimensions table (20%/30%/15%/20%/15%) and again in the formula block, fitting anchor 4 ('efficient; minor instances of over-explanation that could be trimmed') rather than the fully lean anchor 5.

Actionability

Highly concrete for an instruction-only skill: an explicit 0-100 scoring formula, exact banding thresholds (80/60/40) with actions, a 10-step workflow with specifics (3-5 properties, top-10 cutoffs), and a 9-part output format with length guidance. It falls short of anchor 5 because there is no inline worked example of the formula applied and no Ahrefs MCP tool/endpoints named for the data pulls — minor gaps the reference file only partially bridges.

Workflow Clarity

The 10-step workflow is clearly sequenced from competitor-set definition through hand-off, and includes validation steps ('Confirm they share intent and audience', 'Validate intent', unique-territory value audits). It is not 5 because there are no explicit feedback loops or checkpoints (e.g., what to do when SERP overlap is too low or keyword data is thin), though the analysis-only, non-destructive nature of the skill means the destructive-operation cap does not apply.

Progressive Disclosure

The SKILL.md is a well-organized overview and the scoring detail (normalization rules, formula, three worked examples) is correctly split into a single one-level-deep reference, signaled both in workflow step 6 and in a 'Reference files' section with a one-line description. The referenced file exists, is 233 lines, and contains no nested references, matching anchor 5 ('clear overview with well-signaled one-level-deep references; content appropriately split').

Specificity

Names the domain and concrete actions ('Find keywords competitors rank for that the target property does not', 'prioritize them by opportunity', 'Uses Ahrefs MCP for keyword and competitor data') with a named data source. It stops short of comprehensive coverage — clustering and mapping to existing content from the body are absent, matching anchor 4 ('several specific actions; minor gaps in coverage') rather than 5.

Completeness

Explicitly answers both questions: 'what' in the opening sentence (find and prioritize competitor-gap keywords, using Ahrefs MCP) and 'when' via 'Use this skill when planning content investment, identifying quick wins, building a content calendar against a competitor set, or scoping a market entry', followed by concrete trigger phrases. This mirrors the anchor-5 example structure exactly; it is not 4 because the 'when' clause is already explicit and specific, not merely present.

Trigger Term Quality

Lists seven natural trigger phrases ('keyword gap', 'content gap', 'competitor keywords', 'opportunity keywords', 'what should we target', 'where are competitors winning', 'keyword opportunity') plus two situational triggers (new-market planning, losing organic share to a competitor). These are the phrases a user would naturally say in this domain, with synonym-level coverage and no jargon-only terms, matching the anchor-5 example's comprehensiveness.

Distinctiveness Conflict Risk

The competitor-vs-target framing ('keywords competitors rank for that the target property does not') carves out a clear niche distinct from generic keyword research or on-page optimization, and triggers like 'keyword gap' and 'competitor keywords' are unlikely to fire for the wrong skill. Minor residual overlap exists with a general content-strategy skill via 'what should we target', but the consistent competitor-set frame keeps conflict risk minimal, fitting anchor 5.
