Conciseness

The core framework material (key insights, application tables, diagnostics) is dense and valuable, but the body carries clear padding: a full "About the Author" biography of Marty Cagan, affiliate-tagged "Further Reading" book links, and "Why it works" paragraphs restating knowledge Claude already has (e.g., "Large, infrequent releases accumulate risk, delay learning, and create coordination nightmares"). This fits 'mostly efficient but includes some unnecessary explanation'; it does not reach 4 because the padding sections are substantial, though the majority of content earns its place, keeping it above the 2 anchor's pervasive verbosity.

Actionability

For an instruction-only skill the guidance is largely concrete: application tables give specific examples ("Clickable Figma prototype that looks real enough to test task completion", "Ship to 5% of users, measure impact, then expand or roll back based on data"), the Scoring section defines a repeatable procedure ("rate them 0-10... Always provide the current score and specific improvements needed to reach 10/10"), and the diagnostic uses specific thresholds ("10-20 discovery iterations", "5 target users", "every two weeks"). It stops short of 5 because some guidance remains abstract ("Coach stakeholders on the discovery process; pre-sell with opportunity assessments") without concrete steps or scripts.

Workflow Clarity

The body is organized topically (six framework pillars) rather than as a sequenced process. The ingredients of a workflow exist — the Scoring procedure, the Quick Diagnostic's "If No → Action" mapping, and the Common Mistakes fixes — but nothing connects them into an explicit sequence, so checkpoints remain implicit. This matches the 3 anchor ('sequence present but checkpoints missing or implicit') rather than 4, which requires a clear explicit sequence; no destructive/batch-operation cap applies since the skill is advisory.

Progressive Disclosure

All six referenced bundle files exist and references are exactly one level deep (no nested references found inside them), each framework section clearly signals its file ("See: references/discovery-techniques.md"), and a "Reference Files" section describes every file's contents. Minor gaps keep it from 5: discovery-techniques.md is referenced from two different sections, stakeholder-management.md is reachable only through the summary list rather than an inline section link, and the inline sections (concept + why + 6 insights + table + boundary each) are fairly heavy for an overview file.

Specificity

Names several specific actions — "Build empowered product teams using discovery and delivery dual-track", "restructuring product teams away from output-driven models, setting product strategy, or defining what to build next based on outcomes" — matching the several-specific-actions anchor with minor gaps. It falls short of the 5 anchor because the core 'what' is one composite action plus a coverage list ("Covers product discovery techniques, team structure, and continuous value delivery") rather than multiple discrete concrete actions, but sits above the 3 anchor's 1-2 actions.

Completeness

Explicitly answers both questions: what ("Build empowered product teams using discovery and delivery dual-track... Covers product discovery techniques, team structure, and continuous value delivery") and when ("Use when the user mentions..."; "Also trigger when restructuring product teams...") with concrete trigger phrases. This mirrors the 5 anchor's structure precisely; the 4 anchor's 'when could be more explicit' does not apply since triggers are enumerated verbatim.

Trigger Term Quality

Eight natural quoted phrases a product practitioner would actually say — "product discovery", "empowered teams", "feature factory", "product roadmap", "opportunity assessment", "product vision", "product-led growth", "discovery vs delivery" — plus behavioral triggers like "defining what to build next based on outcomes". This is comprehensive natural-term coverage including synonyms, matching the 5 anchor exactly.

Distinctiveness Conflict Risk

Clear niche (empowered product team framework) with distinct, specific triggers, and it actively disambiguates adjacent skills: "For customer interviews, see mom-test. For ongoing discovery systems, see continuous-discovery." Minimal conflict risk, matching the 5 anchor's clear-niche-with-distinct-triggers description.
