Conciseness

The body is efficient — concrete globs, a script invocation, a pattern table, and a YAML output template with no explanations of concepts Claude already knows. A few sentences in Phase 3 ('This history teaches you what to look for. Successful past techniques are strong signals...') restate the obvious and could be trimmed, keeping it at anchor 4 rather than the fully lean anchor 5.

Actionability

Fully executable throughout: specific glob patterns ('lading_payload/benches/*.rs', 'ci/fingerprints/*/lading.yaml'), a runnable script path with its TSV output schema, a 14-row pattern-to-technique table, an exact step-by-step procedure, and a copy-paste-ready YAML result template. This matches anchor 5's 'copy-paste ready commands covering the common cases'.

Workflow Clarity

A clear 7-phase sequence with strong checkpoints: eligibility rules in Phase 1, a mandatory exhaustive hit matrix ('Every cell must have a value. Do NOT skip any combination.'), and a filter gate with an explicit STOP message for the zero-survivors case. It falls short of anchor 5 only because there is no final verification of the top result (e.g., confirming the target function, bench, and fingerprint paths exist) before returning; not a destructive/batch skill, so no cap applies.

Progressive Disclosure

Well-organized phase sections keep the operational content inline where it belongs, and the bundle script (scripts/profile-modules) exists and is referenced by full path, one level deep. Phase 3's navigation is two hops across skills (db.yaml index, then per-entry 'file:' detail files under lading-optimize-hunt/), a minor organization gap that keeps it at anchor 4 rather than anchor 5's clean one-level-deep structure.

Specificity

Names the domain and concrete actions — 'Finds a valid optimization target in lading' and 'Returns a filled target.yaml template with pattern, technique, target, file, bench, and fingerprint' — with only minor coverage gaps (the scanning/analysis the skill performs is not broken out). It lists several specific outputs (anchor 4) rather than just 1-2 actions (anchor 3), but is not the comprehensive multi-action coverage of anchor 5.

Completeness

Explicitly answers 'what' ('Finds a valid optimization target in lading. Returns a filled target.yaml template with...') and 'when' ('Use before /lading-optimize-hunt or when selecting a new optimization target') with concrete trigger phrases. Both are explicit and concrete, matching anchor 5; anchor 4 would require the 'when' to be less specific than it is.

Trigger Term Quality

Natural trigger phrases include 'optimization target', 'lading', 'selecting a new optimization target', and '/lading-optimize-hunt' — terms a user of this codebase would genuinely say. Good keyword coverage (anchor 4), though common synonyms such as 'hot path' or 'allocation' are absent, so it falls short of anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The description names lading, target.yaml, and the sibling skill /lading-optimize-hunt explicitly, giving it a clear niche with distinct triggers and minimal conflict risk (anchor 5). Its only overlap is with the sibling hunt skill, and the 'Use before' clause explicitly positions it as a pre-step rather than a competitor.
