Conciseness

The body is dense and assumes Claude's competence — no space is spent explaining known concepts — but the many negative injunctions ('Do not silently build a generic environment adapter, substitute an unrelated benchmark, or claim RSI has run') could be merged and a few long clauses tightened.

Actionability

Concrete commands appear where needed (launcher block, 'Optional `project inspect --cwd /absolute/project`') and full executable command sets are delegated to references/formal.md, but some preparation directives remain high-level ('Reuse suitable project tests and prepare missing checks or measurements').

Workflow Clarity

The sequence (choose workflow → prepare inputs → hand off or report incomplete) is explicit, with validation checkpoints ('Exercise the actual evaluator on the starting program and verify that it detects a relevant failure'), a readiness checklist grounded in execution evidence, and a clear error-recovery path ('report preparation incomplete... the specific next requirement').

Progressive Disclosure

The 37-line overview links references/formal.md (verified to exist) with clear signaling and a read-timing condition; the reference is one level deep with complete run commands, and operational detail is appropriately split out of SKILL.md.

Specificity

Lists several concrete actions ('fills missing task/evaluation inputs', 'hands a ready environment to the configured AgentPilot runner') with minor gaps — 'improvements' itself stays abstract. Not 5 because coverage isn't comprehensive; not 3 because more than 1-2 actions are named.

Completeness

Clearly answers both: a multi-part 'what' ('Prepare and run AgentPilot improvements... fills missing task/evaluation inputs, then hands a ready environment') and an explicit 'Use when' clause with concrete trigger phrases. Anchor 4's caveat that 'when' could be more explicit does not apply.

Trigger Term Quality

'Use when the user requests AgentPilot or iterative improvement with it' provides two natural terms, but common variations the body itself relies on ('RSI', 'self-improvement', 'improvement run') are missing, so a user phrasing the request without the tool name may not trigger it.

Distinctiveness Conflict Risk

The named-tool niche ('AgentPilot' in both what and when) gives it distinct triggers with minimal conflict risk; 'iterative improvement with it' is bound to the tool name, keeping overlap with generic improvement skills negligible.
