The body is accurate and well-organized but spends many tokens arguing for its own conventions (e.g. the multi-paragraph justifications of the 10/25-point cuts and the 2/5/15% flake bands) and restates the source citations repeatedly. It is mostly efficient but could be tightened without losing the load-bearing reasoning.

Concrete executable guidance throughout: explicit tier matching rules with path strings and import names ('Path contains e2e/, cypress/, playwright/... or imports @playwright/test'), a precise ROI formula 'roi(layer) = defects_caught(layer) / total_run_minutes(layer)', and a fully specified output template. The instruction is specific enough to apply directly.

Five clearly sequenced steps with first-match-wins ordering, an explicit 'Cannot assess' gate (under 3 files, confidence <80%, no target), and validation feedback ('If no per-run history exists, this axis emits not assessed and the audit continues'; 'name the specific input that would unlock it'). Checkpoints and error-recovery paths are explicit.

The body is a well-organized overview and offloads the bulky worked examples to a real one-level-deep reference, signaled as '[references/examples.md](references/examples.md)'. The reference file exists and matches the link, and navigation is clearly signaled with no nested indirection.

Lists multiple concrete actions: 'per-file tier classification (unit / integration / E2E, first match wins)', 'pyramid ratio against whatever target the team already committed to', 'per-layer flake rate', and 'defects-caught-per-run-minute ROI per tier', then 'reduces them to one categorical verdict'. These are four specific, named measurements plus the reduction step, matching the multiple-concrete-actions anchor.

It explicitly answers both: what it does ('Measures an existing test suite's current state on four axes...') and when to use it ('Use when a suite has grown for a year or more without review and someone needs a defensible read...'). Both halves are present and explicit, matching the score-3 anchor.

It contains natural terms a user might say ('test suite', 'healthy, over-grown, or structurally inverted', 'delete or rewrite'), but the trigger framing is a long situational clause rather than crisp keyword variations like 'test pyramid', 'flake rate', 'test suite health'. Coverage is relevant but not the breadth of common variations that would earn a 3.

It carves a clear niche and explicitly names what it does NOT own ('choosing the target... belongs to a pyramid-balancing capability such as test-pyramid-balancer'), making it unlikely to fire for the related balancing or change-shape skills. This is a clear niche with distinct triggers.
