Conciseness

The body is dense and operational, assuming domain knowledge (Kotler criteria, FPC, AAPOR) rather than explaining basics, but the 5-question forcing-question library with per-question Recommended/Canon lines and the 'Distinct from' table partially duplicate the references section and the frontmatter description. Efficient with minor instances that could be trimmed, matching the 4 anchor rather than the 5 ('every token earns its place') or the 3 (noticeable padding).

Actionability

Fully executable, copy-paste-ready commands with real flags throughout: 'market_sizer.py --input market.json --method both --profile {b2b-saas|consumer|enterprise|marketplace|hardware|services}', 'sample_size_planner.py --population 62000 --confidence 0.95 --moe 0.05', onboarding and autoresearch invocations, plus a scripts table documenting '--help', '--sample', '--output {human,json}'. Specific examples cover the common cases, matching the 5 anchor.

Workflow Clarity

A clear 5-step workflow (brief → size → plan → score → assemble) with explicit validation checkpoints ('Reconcile the top-down/bottoms-up delta before quoting anything', 'Drop segments failing the substantiality/accessibility gate', 'Lock 1-2 before opening 3-5'). It falls short of the 5 anchor because recovery from a failed triangulation is only implicitly handled — the body says to reconcile the delta and offers the opt-in autoresearch loop, but gives no direct fix-and-revalidate loop in the main workflow.

Progressive Disclosure

The References section clearly signals three one-level-deep files with one-line scope descriptions, all verified to exist, and the scripts table maps each tool to its purpose. It does not reach 5 because the 25-line forcing-question library with canon citations is inline content that belongs in a reference file, keeping the overview slightly heavier than a clean split.

Specificity

Three concrete, comprehensive capabilities are named: 'sizing a market as TAM/SAM/SOM computed BOTH top-down and bottoms-up (never a single unsourced number)', 'planning a survey sample size with finite-population correction and per-segment minimums', and 'scoring candidate market segments against Kotler's measurable/substantial/accessible/differentiable/actionable criteria'. This lists multiple specific concrete actions with comprehensive coverage, matching the 5 anchor; the 4 anchor's 'minor gaps in coverage' does not apply.

Completeness

It explicitly answers both what and when: 'Use when doing upstream market-research methodology — sizing a market... planning a survey sample size... or scoring candidate market segments' gives concrete trigger activities, and 'Outputs always show the method and the assumptions' plus 'For market-research analysts and product-marketing at the sizing/survey/segmentation moment' add the output contract and audience. Clearly matches the 5 anchor.

Trigger Term Quality

Good keyword coverage of natural terms users would say — 'market-research', 'TAM/SAM/SOM', 'sizing', 'survey', 'sample size', 'segmentation', 'market segments'. A few natural synonyms are missing (e.g. 'addressable market', 'market analysis', 'market opportunity', 'competitive intelligence' — the last appears only in the body), so it fits the 4 anchor ('a few natural terms missing') rather than the 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

'Distinct from marketing-skill (campaign analytics, attribution, demand-gen) — this is the evidence-building methodology, not live-campaign optimization' draws an explicit boundary against the nearest neighbor, and the upstream framing separates it from positioning/pricing skills. Clear niche with distinct triggers and minimal conflict risk, matching the 5 anchor.
