Conciseness

The core sections (How It Works, Examples, Key Features) are dense and information-rich, but the Installation section spends ~20 lines on generic git mechanics Claude already knows ('git fetch origin main', 'git log --oneline HEAD..origin/main', 'git checkout <reviewed-full-sha>'), and the 'Zero runtime risk' bullet over-explains ('no hooks, no shell scripts, no executable code, no package.json, no build step...'). Mostly efficient but with some unnecessary explanation that could be trimmed — not 4, where over-explanation would be only minor instances.

Actionability

The 5-phase pipeline is described with real specifics (pre-flight checks, 3–12 one-PR-sized steps, plans/ output with context briefs and exit criteria, executable invocations like '/blueprint myapp "migrate database to PostgreSQL"'), but headline mechanisms — 'a checklist and anti-pattern catalog' and the 'plan mutation protocol' — are named without any content, and no reference files exist for them. Key details are missing, so a fresh agent would have to invent the review checklist; not 4 because these gaps are central rather than minor.

Workflow Clarity

The numbered 5-phase pipeline is a clear sequence with most checkpoints present: pre-flight checks, per-step 'verification commands, and exit criteria', a review gate that 'fixes all critical findings before finalizing' (a feedback loop), and 'invariants verified after every step'. Not 5: the review checklist contents are unspecified and error-recovery detail beyond the review gate is thin; not 3 because validation checkpoints are explicitly woven through the sequence.

Progressive Disclosure

Section headers are clear and nothing is a monolith or nested-reference maze, but the skill's flagship artifacts — anti-pattern catalog, review checklist, and plan mutation protocol — are name-dropped with neither inline content nor reference files anywhere in the bundle (no references/ directory exists). At ~90 lines (above the under-50-line simple-skill exception), the disclosure structure is incomplete; not 4 because the missing detail is more than a minor organization gap for features the skill leads with.

Specificity

The description enumerates multiple concrete capabilities — 'Turn a one-line objective into a step-by-step construction plan', 'self-contained context brief so a fresh agent can execute it cold', and 'adversarial review gate, dependency graph, parallel step detection, anti-pattern catalog, and plan mutation protocol' — comprehensively covering the skill's feature set with no vague filler. Not 4: the enumeration has no coverage gaps relative to what the skill claims to do.

Completeness

Both questions are explicitly answered: the first three sentences state concretely what the skill does, and 'TRIGGER when... DO NOT TRIGGER when...' gives explicit when-to-use guidance with concrete trigger phrases. This matches the anchor-5 example pattern ('what' + 'Use when...' with concrete triggers) exactly; score 4 would require the when-clause to be less explicit, which it is not.

Trigger Term Quality

Trigger phrases 'user requests a plan, blueprint, or roadmap for a complex multi-PR task, or describes work that needs multiple sessions' provide comprehensive natural-term coverage including synonyms (plan/blueprint/roadmap) and scenario phrasing, sharpened by a negative trigger ('task is completable in a single PR... or user says "just do it"'). These are words a user would naturally say when needing this skill.

Distinctiveness Conflict Risk

The niche (multi-session, multi-PR construction planning with dependency graphs) is clear and the multi-PR/multi-session qualifiers plus negative triggers mostly disambiguate from generic planning skills. Not 5: the bare trigger words 'plan' and 'roadmap' still carry minor overlap risk with ordinary planning requests that don't involve multiple sessions or PRs.
