The body avoids explaining concepts Claude already knows, but the 'Selection criteria' (7 axes) and 'Player taxonomy — axes to populate across' (8 axes) sections substantially overlap — size/model, specialization, geography/market, pricing/engagement, distinctiveness, and brand strength all appear in both — so it could be tightened, matching the 'mostly efficient but could be tightened' anchor rather than the lean score-3 anchor.

It provides concrete executable guidance — a filled-in scoring-matrix table template with named columns, eight named axes with explicit poles, tier definitions, a named data-source list, and a fully worked example with populated tables — satisfying the 'specific examples, copy-paste ready' bar for an instruction skill.

The process is sequenced (positioning brief → selection criteria → axis plotting → tiering → sources → scoring → output) with explicit checkpoints — 'Do not proceed without the positioning brief', 'verify claims across at least two sources', and the scoring matrix as a pre-filter gate — and the worked example reinforces the Step 1/2/3 order, matching the 'clear sequence with explicit validation steps' anchor.

The skill is a single ~205-line file with no bundle files and no content split into one-level-deep references; headers and navigation are clear, but content that could be separate (the full worked example, the detailed axis taxonomy) is inline, matching the 'content that should be separate is inline' anchor rather than the score-3 'content appropriately split' anchor.

The description lists multiple concrete actions — 'identifying, categorising, and score-filtering a competitor set' and 'Decides who counts as a competitor, which tier they belong to, and which sources to mine' — matching the 'lists multiple specific concrete actions' anchor rather than the score-2 'some actions' anchor.

It explicitly answers both what (identifying/categorising/score-filtering competitors, assigning tiers, mining sources) and when via an explicit 'Use when scoping a competitive landscape ... before any benchmarking begins' trigger, hitting the 'clearly answers both what AND when' anchor.

It surfaces natural terms a user would actually say — 'competitive landscape', 'competitor set', 'benchmarking' — giving good coverage; it is not the score-2 case of 'missing common variations'.

It carves a clear niche — first step of a three-skill competitive pipeline that 'precedes benchmark-methodology' — with distinct triggers unlikely to fire for the wrong skill, matching the 'clear niche with distinct triggers' anchor.
