Conciseness

Dense, table-driven body that assumes Claude's competence (no basic PMF or north-star explanations), with only minor trim candidates: the Keywords section duplicates the frontmatter triggers and the generic 'Reasoning Technique: First Principles' section adds little skill-specific value. Not a 5 because those few padded sections could be cut; not a 3 since almost everything else earns its tokens.

Actionability

Two verified, copy-paste-ready commands (`python scripts/pmf_scorer.py`, `python scripts/portfolio_analyzer.py`) that run on built-in sample data, plus concrete thresholds ("D30 retention is below 20% (consumer) or 40% (B2B)") and a request→artifact table. Minor gaps keep it below 5: no inline example of the scripts' JSON input format and no concrete procedure for non-script tasks like board prep or org design.

Workflow Clarity

A rough sequence exists ("Always read company-context.md before responding", Quick Start commands, Output Artifacts mapping) but no explicit end-to-end workflow (e.g., collect data → run scorer → map to invest/maintain/kill → cross-check Red Flags) and validation checkpoints are only implicit or deferred to the external agent-protocol file. This matches anchor 3's 'sequence present but checkpoints missing or implicit'; nothing is destructive or batch, so no cap applies, but it also lacks the explicit validation steps of anchor 4.

Progressive Disclosure

Good structure against the actual bundle: a Resources table with a 'When to load' column signals all five existing bundle files (verified present), references are one level deep with no cross-nesting, and detail-heavy material (frameworks, playbooks) is correctly split out. Minor gaps: `../agent-protocol/SKILL.md` dangles outside this bundle, and the ~200-line body inlines sizable dashboard and C-suite-integration tables that could partly live in references.

Specificity

The description names its domain and several specific capability areas ("Product vision, portfolio strategy, product-market fit, and product org design") but presents them as topic nouns rather than concrete actions, sitting between anchor 2's minimal actions and anchor 4's list of specific action verbs like 'extracts' or 'fills'.

Completeness

Explicitly answers both what ("Product leadership for scaling companies. Product vision, portfolio strategy, product-market fit, and product org design") and when ("Use when setting product vision... or when user mentions CPO, product strategy...") with six 'Use when' clauses plus five user-mention triggers, matching the anchor-5 example pattern. Below 5 would apply only if the 'when' were less explicit, which it is not.

Trigger Term Quality

Good natural trigger phrases users would actually say ("setting product vision", "measuring PMF", "reporting to the board on product", "CPO"), but a few natural synonyms are missing such as the spelled-out "chief product officer", "product roadmap", or "product team structure".

Distinctiveness Conflict Risk

Clear CPO-level niche with distinct triggers ("CPO", "product-market fit", "portfolio prioritization") unlikely to fire for unrelated skills; minor overlap risk remains with lower-level product-management or general strategy skills via broad terms like "product strategy" and "roadmap strategy", keeping it just below the minimal-conflict anchor 5.
