Conciseness

The body is lean overall — prescriptive guidance like "Opportunity Score = Importance × (1 − Satisfaction), normalized to 0–1" and "RICE adds Reach as a separate factor for larger teams" adds skill-specific recommendations rather than generic padding. Minor trims are possible ("Think step by step", restating well-known ICE/RICE definitions), so it fits anchor 4's 'minor instances of over-explanation' rather than anchor 3's 'some unnecessary explanation'.

Actionability

Concrete guidance is present: four evaluation dimensions each with probing questions ("How much does it move the needle on desired outcomes?"), a specified deliverable ("Clear ranking (1-5)", "Brief rationale", "Key trade-offs considered", "What was deprioritized and why"), and named frameworks to apply. It falls short of anchor 5 because the scoring mechanics — how to weigh impact vs. effort vs. risk into a ranking — are left implicit, a minor gap consistent with anchor 4.

Workflow Clarity

The four steps are clearly sequenced ("1. Understand priorities" → "2. Evaluate each feature" → "3. Recommend the top 5 features" → "4. Present as a prioritization table"), with a confirmation checkpoint in step 1 ("Confirm the product objective and success metrics"). It is not a destructive or batch operation, so no validation cap applies, but there are no explicit output-validation or feedback steps, keeping it at anchor 4 rather than anchor 5's 'explicit validation steps; feedback loops'.

Progressive Disclosure

The body is under 50 lines with no bundle files, and per the simple-skill guideline progressive disclosure can score 5 with just well-organized sections. Sections are clear (Context, Domain Context, Instructions, Further Reading), the `prioritization-frameworks` reference is one level deep and clearly signaled, and the Further Reading links are external URLs plainly labeled — no buried or nested references.

Specificity

"Prioritize a backlog of feature ideas based on impact, effort, risk, and strategic alignment with top 5 recommendations" names a concrete action, the four evaluation criteria, and a specific deliverable (top 5 recommendations). It stops short of anchor 5's comprehensiveness (only one core action, e.g., no mention of reading input files/backlogs), but exceeds anchor 3's '1-2 concrete actions' minimal coverage.

Completeness

The description explicitly answers both questions: what ("Prioritize a backlog of feature ideas based on impact, effort, risk, and strategic alignment with top 5 recommendations") and when ("Use when prioritizing a feature backlog, making scope decisions, or ranking product ideas") with concrete trigger phrases. This matches the anchor 5 example structure (what + explicit 'Use when...' triggers), not anchor 4 where the 'when' could be more specific.

Trigger Term Quality

"Use when prioritizing a feature backlog, making scope decisions, or ranking product ideas" provides good natural-phrase coverage. It misses common synonyms a user might say ("roadmap", "which features should we build next", "backlog grooming"), so it falls short of anchor 5's comprehensive synonym coverage but is clearly above anchor 3's 'missing common variations'.

Distinctiveness Conflict Risk

The feature-backlog prioritization niche with explicit criteria (impact, effort, risk, strategic alignment) is mostly distinct from other skills. Minor overlap risk remains with general planning/roadmapping or decision-making skills, keeping it below anchor 5's 'clear niche with minimal conflict risk' but above anchor 3's 'could still overlap with similar skills'.
