Conciseness

The body is dense with substantive, project-specific rules and explains nothing Claude would already know, but it could be meaningfully tightened: the tracker-only-medium rule is restated across 'Map home', the migration paragraph, and 'Scope and non-goals'; 'decisions, never deliverables' and 'one ticket per session' are each repeated several times; and the nautical framing plus long compound sentences add tokens without adding rules. More than the 'minor instances' of anchor 4, but far from the padded filler of anchor 2.

Actionability

For an instruction-only skill the guidance is fully concrete: two numbered procedures with unambiguous steps, a copy-paste-ready map body template, a ticket-type table giving the exact resolution mechanism per type ('Call the Skill tool with "deep-interview"', 'spawn a background subagent', 'Call the Skill tool with "loft"'), an exact index-line format ('[<ticket title>](link): <one-line gist>'), a named command ('node scripts/shipyard-audit.mjs'), and verbatim exit and session-close phrasings. The common charting, working, and exit cases are all covered specifically.

Workflow Clarity

Both multi-step processes are clearly sequenced, and validation checkpoints are explicit: the fog test (Q1/Q2) gates entry, W1 and W2 are captain signatures ('present the destination statement and get explicit confirmation', 'iterate until signed'), the migration path requires 'verify every decision, resolution, and dependency is represented before declaring the import complete', and claiming-before-work plus close-as-not-planned rules handle concurrency and out-of-scope tickets. Feedback loops (re-interview rounds, iterate-until-signed, import verification) are present for the risky tracker operations.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), so all content lives in SKILL.md, and it is well organized: clear section headers, a ticket-type table, and a fenced map-body template make navigation easy, and pointers to companion skills (deep-interview, loft, drydock, launch) are one level deep. It falls short of anchor 5 because two dense inline blocks — the one-time local-map migration paragraph and the legacy-yards (CONTEXT.md) sediment rules — are exactly the kind of specialized, rarely-needed detail that would earn its place in a separate reference file instead of the always-loaded body.

Specificity

The description lists several concrete actions — 'chart a foggy effort... into a map of decision tickets on the repo's issue tracker', 'work the frontier one ticket per session', 'hand the collapsed decisions to /launch as a mission brief' — with a named medium and a clear output contract ('produces decisions, never deliverables'). It falls short of anchor 5 because the metaphorical framing ('Shipyard's navigator', 'wayfinding, not building') substitutes abstraction where a plainer action statement would be more concrete.

Completeness

The 'what' is clearly stated (chart a foggy effort into a map of decision tickets, work the frontier one ticket per session, hand off a mission brief), and the 'when' is present as explicit trigger guidance in the parenthetical '(destination unclear, questions not yet stateable)'. It is not anchor 5 because there is no 'Use when...' phrasing and the trigger condition is embedded in a definition rather than stated as a standalone trigger clause.

Trigger Term Quality

Some concept-level trigger phrases are present — 'destination unclear', 'questions not yet stateable' — but they are phrased in the skill's idiosyncratic vocabulary ('foggy effort', 'the frontier', 'wayfinding') rather than natural user phrasing like 'vague idea', 'unclear requirements', 'break down this project', or 'planning'. It is above anchor 2 (more than one or two keywords, and the conditions are relevant) but below anchor 4 because few terms are ones a user would actually say.

Distinctiveness Conflict Risk

The description carves a clear niche — decision-ticket mapping on an issue tracker, one resolution per session, explicit handoff to /launch, 'produces decisions, never deliverables' — with triggers ('foggy effort', 'residual questions', map continuation) that are unlikely to fire for any other skill.
