The body is mostly efficient — no basic-concept padding, dense tables and code blocks, and bulky CI/tree detail correctly externalized — but the Overview paragraph re-states the description's producer-consumer point and the ~215-line body could be tightened, matching score 2's "mostly efficient but could be tightened" rather than score 3's "every token earns its place".

Provides fully executable, copy-paste-ready commands throughout (git clone, docker build, restler compile/test/fuzz-lean/fuzz with concrete flags, a curl|jq auth-dict snippet, and a complete GitHub Actions YAML in the reference), matching the score-3 anchor rather than score 2's pseudocode/incomplete guidance.

The four-stage workflow is clearly sequenced with an explicit validation checkpoint at Stage 2 ("If endpoint coverage is below ... 80%+, stop and amend") and a per-bug triage feedback loop (replay log → restler replay → ticket), matching score 3's explicit validation and error-recovery loops rather than score 2's missing checkpoints.

A clear overview in SKILL.md points via two well-signaled one-level-deep links to references/triage-and-ci.md (verified to hold the output tree and full CI workflow), with appropriately split content; matches score 3 rather than score 2's inline-bloat or unclear signaling.

Lists multiple concrete actions ("infers producer-consumer dependencies", "drives sequences of requests (POST → GET → DELETE chains)", "reports 5xx errors, resource leaks, and hierarchy violations", "Wraps the canonical 4-stage workflow"), matching the score-3 anchor; it is not score 2 because the action set is comprehensive rather than partial.

Explicitly answers both what (runs fuzzing, infers dependencies, drives sequences, reports bug categories) and when ("Use when the API is stateful ... and Schemathesis's stateless fuzzing is missing the multi-step bugs"), matching the score-3 anchor with an explicit trigger clause.

Uses natural practitioner terms — "stateful REST API fuzzing", "OpenAPI spec", "resources are created, queried, modified, deleted", and "Schemathesis's stateless fuzzing is missing the multi-step bugs" — that a user would actually say, matching score 3 rather than score 2's partial keyword coverage.

Clear niche (stateful REST API fuzzing via RESTler) explicitly contrasted against Schemathesis's stateless fuzzing, giving distinct triggers unlikely to fire for the wrong skill; matches score 3 rather than score 2's residual overlap.
