Conciseness

The body is dense and imperative throughout — tables for responsibilities, metrics, postures, and red flags with no concept tutorials and no padding; it assumes Claude knows frameworks like BCG and team topologies by name only. Not 5 because of minor trimmable material: the 'Keywords' section duplicates trigger terms already in the frontmatter description, and the Communication section restates an external protocol ('see ../agent-protocol/SKILL.md') in detail. Not 3 because there is no over-explanation — every section delivers operational content (thresholds, frequencies, question sets).

Actionability

Concrete and specific throughout: runnable commands ('python scripts/pmf_scorer.py', 'python scripts/portfolio_analyzer.py'), hard thresholds ('D30 retention is below 20% (consumer) or 40% (B2B)'), named frameworks (RICE/ICE, Sean Ellis, team topologies), and a request→artifact table mapping deliverables. Not 5 because the script invocations specify no inputs (what data file or format the scorer/analyzer takes), so a user cannot actually run them copy-paste from this file alone. Not 3 because the guidance for an instruction-only skill is concrete and executable in nearly all sections.

Workflow Clarity

The content supplies raw material (diagnostic question sets, red flags, output artifacts) and an explicit output-verification loop ('Self-verify: source attribution, assumption audit, confidence scoring', 'Peer-verify', 'Critic pre-screen'), but the core advisory workflows are never sequenced — there is no step-by-step path from a request like 'Do we have PMF?' through gathering data, running diagnostics, to producing the artifact. Not 4 because a clear sequence with most checkpoints present would connect request → analysis → validated output; here the sequence and its checkpoints are implicit, and key verification detail is delegated to a file outside this bundle ('../agent-protocol/SKILL.md'). Not 2 because a rough structure does exist (Quick Start → responsibilities → diagnostics → artifacts) and validation guidance is explicitly stated in the Communication section.

Progressive Disclosure

In-file organization is good: a Resources table with per-file 'when to load' guidance and clearly signaled one-level-deep references. However, scoring against the actual bundle structure, none of the referenced files exist — references/product_strategy.md, references/product_org_design.md, references/pmf_playbook.md, scripts/pmf_scorer.py, and scripts/portfolio_analyzer.py are all absent from the bundle, as are '../agent-protocol/SKILL.md' and 'company-context.md'. Not 4/5 because navigation as written leads to missing files, and detailed content that the missing references presumably cover (dashboard tables, north star examples, red flags) remains stranded inline in SKILL.md. Not 2 because the in-body structure itself is well organized and references are clearly, prominently signaled rather than buried.

Specificity

The 'what' section names the domain and its concrete sub-areas ('Product vision, portfolio strategy, product-market fit, and product org design'), and the 'Use when' clause adds several concrete actions ('setting product vision, managing a product portfolio, measuring PMF, designing product teams, prioritizing at the portfolio level, reporting to the board on product'). Not 5 because the what-section is a noun-phrase enumeration rather than verb-led concrete actions, and it omits the tangible outputs (PMF scorecard, portfolio map, org proposal). Not 3 because it far exceeds 1-2 actions — six concrete actions plus four specific capability areas are explicitly stated.

Completeness

Both questions are explicitly answered: 'Product leadership for scaling companies. Product vision, portfolio strategy, product-market fit, and product org design.' states what the skill covers, and 'Use when setting product vision, ... or when user mentions CPO, product strategy, ...' gives concrete trigger phrases for when to invoke it. This matches the anchor 5 example structure (what + 'Use when' with explicit trigger phrases).

Trigger Term Quality

The 'when user mentions' clause covers strong natural terms: 'CPO, product strategy, product-market fit, product organization, portfolio prioritization, or roadmap strategy', plus 'PMF' appears in the action list. Not 5 because a few natural synonyms are missing — 'chief product officer' spelled out, 'product roadmap', 'product team(s)', 'north star' — and there are no equivalent phrasings beyond the ones listed. Not 3 because coverage is genuinely good and includes the primary ways a user would phrase this need, not just technical jargon.

Distinctiveness Conflict Risk

The description carves a clear niche (CPO-level product leadership: portfolio, PMF, product org design) with distinct triggers like 'CPO' and 'portfolio prioritization'. Not 5 because broad phrases such as 'product strategy' and 'roadmap strategy' overlap with adjacent skills a suite would likely contain (CEO strategy, product-manager, roadmap-prioritization skills). Not 3 because the C-suite framing and PMF/org-design specifics make mis-triggering unlikely.
