The body is mostly efficient and avoids explaining concepts Claude already knows, but it is long (~330 lines) with notable redundancy — the 'Common opportunities by category' section restates content from the '5 levers' section (reserved/committed-use pricing and spot instances appear in both), matching the score-2 'could be tightened' anchor; it is not 3 because the duplication inflates length beyond what every token needs to earn.

As an instruction-only skill the guidance is concrete and specific — 'Start the conversation 60-90 days before renewal', 'Reserved or committed-use pricing (1-3 year commitments at 30-70% discount)', a concrete 2x2 prioritization scheme, and a defined output format — matching the score-3 anchor adapted to actionable non-code guidance; it is not 2 because no key details are missing or vague.

The 10-step workflow is a clear sequence with validation/feedback loops where the steps are risky — Step 6 includes 'Monitor for unexpected impact' and 'Confirm cost reduction in next billing cycle', and rightsizing carries a 'test in staging first' note — matching the score-3 anchor; it is not 2 because checkpoints are present for the destructive/batch operations.

The body is a clear overview with a single, well-signaled, one-level-deep reference — the 'Reference files' section links references/cloud-audit-checklist.md with a one-line description and the file exists and is appropriate — matching the score-3 anchor; it is not 2 because the reference is clearly signaled and not nested.

The description lists multiple specific concrete actions — 'reviewing monthly cloud or SaaS spend, finding unused resources, rightsizing infrastructure, negotiating vendor contracts, deciding what to consolidate, or planning for budget cuts' — matching the score-3 anchor; it is not the level below because it enumerates a comprehensive set of distinct actions rather than naming only some.

It explicitly answers both 'what' (audit and reduce infrastructure/tooling costs) and 'when' via a clear 'Use this skill when...' clause plus an explicit 'Triggers on...' list, matching the score-3 anchor; it is not level 2 because the trigger guidance is explicit rather than implied.

It provides broad coverage of natural trigger terms users would say — 'cost optimization, cloud spend, SaaS spend, rightsizing, unused resources, FinOps, infrastructure audit, vendor consolidation, budget cut, cost review' — plus situational triggers ('finance flags rising costs', 'contract renewal is up'), matching the score-3 anchor.

It carves a clear FinOps/cost niche with distinct triggers unlikely to fire for the wrong skill, matching the score-3 anchor; it is not level 2 because the scope is specific and unlikely to overlap with unrelated skills.
