Conciseness

The body is procedural and free of explanations of concepts Claude already knows, but several passages restate the same instruction many times: rule 8 spends ~250 words hammering per-file confirmation ('a prose summary, a change list, an excerpt, or a grouped description... is not a diff... Asking ends the turn... A question and the write it asks about cannot share a turn'), and step 6's brownfield note ('those are different documents, and a reader of AGENTS.md never sees them') and step 10's recording paragraph are similarly padded. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' — above level 2 because the padding is confined to a few passages rather than pervasive.

Actionability

Fully executable guidance throughout: verbatim bash commands ('deno run --allow-read <skill-dir>/scripts/generate_agents.ts .'), a complete copy-paste interview prompt with the exact JSON return schema, exact merge rules per legacy file, exact template paths and section names ('### Detected Commands', '### Command Scripts'), and concrete JSON fields to check ('opencode_json.has_subdirectory_globs'). Matches the level-5 anchor: copy-paste ready commands with specific examples covering the common cases.

Workflow Clarity

Twelve clearly sequenced steps with explicit Greenfield/Brownfield conditions, an agent-judgment decision point, per-file diff confirmation gating every destructive write, and a final verification checklist with a re-run feedback loop ('If passed is false (exit code 1), fix the issues before proceeding'). This matches the level-5 anchor (explicit validation steps, feedback loops for error recovery, checklists); despite involving overwrites and deletions, the per-file confirmation and re-verification satisfy the destructive-operation cap.

Progressive Disclosure

The 38KB AGENTS.template.md is appropriately externalized to assets/, references are clearly signaled at point of use and are one level deep, and every referenced path (assets/AGENTS.template.md, assets/SRS.template.md, assets/SDS.template.md, scripts/generate_agents.ts) exists and matches what the body claims about it. Short of level 5 because some template detail is duplicated inline — step 9 restates the full SRS/SDS field structure ('## 3. Functional Reqs' with the five per-FR fields, '## 3. Components' with Purpose/Interfaces/Deps) that already lives in the tiny template files — and rule 8's long prose is main-body content that could live in a reference.

Specificity

The description names concrete artifacts — 'writes AGENTS.md and the documentation skeleton for a new or an existing codebase' — but stops at 1-2 actions; it omits other core capabilities (CLAUDE.md symlink, the greenfield interview, legacy-layout collapse, dev-command setup). This matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive', and is below level 4 ('several specific actions; minor gaps') because most of the skill's actions are unlisted, while above level 2 because what it does state is concrete, not generic.

Completeness

It explicitly answers both questions: 'Use when the user asks to set a project up for flowai for the first time' (when, with a concrete trigger phrase) and 'writes AGENTS.md and the documentation skeleton' (what), plus a negative boundary ('Not for reconciling an existing AGENTS.md with newer templates'). This matches the level-5 anchor (both what and when with concrete trigger phrases); level 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

'Use when the user asks to set a project up for flowai for the first time' is a natural multi-word trigger, reinforced by 'for a new or an existing codebase' covering both scope cases. It sits between anchors: better than 3 ('some relevant keywords but missing common variations') because the main trigger phrase is genuinely what a user would say, but short of 5 because common synonyms such as 'initialize', 'bootstrap', 'scaffold', or 'onboard' are absent.

Distinctiveness Conflict Risk

'flowai' is a niche proper noun, the first-time condition narrows the trigger, and the explicit exclusion ('Not for reconciling an existing AGENTS.md with newer templates') separates it from an adjacent maintenance skill. Clear niche with distinct triggers and minimal conflict risk — the level-5 anchor.
