Conciseness

The body is lean and dense — checklists, tables, and quantified red flags ('>30% revenue from 1 customer', '$1-3M per engineer') with zero explanation of concepts Claude already knows. Every section adds non-obvious value (e.g., naming the specific sources to verify multiples against), matching the 'every token earns its place' anchor.

Actionability

Highly actionable for an instruction-only skill: quantified red-flag thresholds, named verification sources with a 'cross-check at least two' rule, a numbered preparation sequence, and exact sibling-script paths to run ('term_sheet_analyzer.py', 'ai_training_data_audit.py') with pass/fail conditions ('Any 🔴 finding goes to outside counsel before signing').

Workflow Clarity

Both Quick Start sequences are explicit (rationale → screening → DD → valuation → negotiation → integration; readiness → data room → advisor → negotiation → transition), and the 'Verification Loop (before any LOI or signature)' adds explicit validation gates and a feedback loop ('Loop the findings back into the negotiation-points table before the next counter') plus checklists for the DD domains — matching the top anchor.

Progressive Disclosure

Section structure and reference signaling are good, but the body cites 'references/integration-playbook.md' and 'references/due-diligence-checklist.md' (both in the Integration Frameworks section and again in Resources) and neither file exists in the bundle — the references/ directory is absent entirely. Scoring against the actual bundle structure, navigation breaks at the point of use, which is a bigger defect than the 'minor organization gaps' of anchor 4 but the structure is still far better than anchors 1-2.

Specificity

The description lists several specific workstreams — 'Due diligence, valuation, integration, and deal structure' — with two-sided framing ('acquiring companies or being acquired'), matching the anchor for several specific actions with minor gaps. It is not a 5 because the capabilities are domain nouns rather than fully concrete actions and coverage has minor gaps (e.g., LOI/term-sheet review is covered in the body but not mentioned).

Completeness

It explicitly answers both: what — 'M&A strategy for acquiring companies or being acquired. Due diligence, valuation, integration, and deal structure.' and when — 'Use when evaluating acquisitions, preparing for acquisition, M&A due diligence, integration planning, or deal negotiation.' This matches the anchor for clear what AND when with concrete trigger phrases.

Trigger Term Quality

'Use when evaluating acquisitions, preparing for acquisition, M&A due diligence, integration planning, or deal negotiation' provides good natural-phrase coverage a user would actually say. A few natural terms are missing ('mergers', 'selling the company', 'LOI', 'term sheet', 'acqui-hire') — several of which the body itself lists as keywords — so it falls short of the comprehensive anchor 5 but sits above anchor 3.

Distinctiveness Conflict Risk

M&A is a clear niche with distinct triggers, but 'valuation' and 'deal negotiation' overlap with the closely related cfo-advisor and general-counsel-advisor skills that this skill's own body delegates to, creating minor overlap risk — matching the 'mostly distinct; minor overlap risk with closely related skills' anchor rather than anchor 5.
