Conciseness

The body is lean and every section earns its place: a compact decision table, terse output-format contracts, one-line rules ('if you'd want the subagent's output in 1/3 the tokens, pick cavecrew'), and a short 'What NOT to do' list. Nothing explains concepts Claude already knows — even the 'Why this exists' section adds non-obvious project-specific math (2k vs ~700 tokens per delegation).

Actionability

For an instruction-only skill the guidance is fully actionable: a task-to-agent decision table covering common cases, exact output contracts (e.g. 'verified: <re-read OK | mismatch @ path:line>'), concrete chaining patterns, and explicit failure tokens ('too-big.', 'ambiguous.'). Per the rubric's code-vs-instruction note, the absence of code is not penalized when guidance is this concrete.

Workflow Clarity

The 'Locate → fix → verify' chain is clearly sequenced and includes real checkpoints (builder's 'verified:' field, reviewer audit in step 3). It falls short of a 5 because the recovery loop after a reviewer finding — and the retry path when the builder returns 'too-big.' or 'ambiguous.' — is implied rather than spelled out.

Progressive Disclosure

The skill is a single ~70-line file with no bundle directories (references/, scripts/, assets/ are absent) and no content that warrants splitting; all sections are well-organized, clearly headed, and easy to navigate, which fits the simple-skill exception for well-organized single-file skills.

Specificity

Names multiple concrete actions with the three specific subagents and their roles ('spawn `cavecrew-investigator` (locate code), `cavecrew-builder` (1-2 file edit), or `cavecrew-reviewer` (diff review)') plus the quantified compression benefit ('~60% smaller'). Coverage is comprehensive for its domain and stays in third-person voice throughout.

Completeness

Explicitly answers both 'what' (decision guide for delegating to three named subagents with compressed output) and 'when' (an explicit 'WHEN to spawn' clause plus a 'Trigger:' phrase list). Matches the anchor for clearly answering both with concrete trigger phrases.

Trigger Term Quality

The explicit trigger list ('delegate to subagent', 'use cavecrew', 'save context', 'compressed agent output') gives good keyword coverage, but several entries are internal/technical phrasings rather than natural user language — natural variations like 'compress output', 'save tokens', or 'shrink context' are missing.

Distinctiveness Conflict Risk

Occupies a clear niche (caveman-compressed delegation) and explicitly differentiates from vanilla alternatives ('instead of doing the work inline or using vanilla `Explore`'), so conflict risk with other skills is minimal.
