Conciseness

The body is ~15 lines of pure routing instruction with zero concept explanation — every line directs an action ("read the matching file in commands/", "read skills/controller.md", "stop and report the error to the user. Do not advance"). Matches the 'lean and efficient; every token earns its place' anchor; nothing could be trimmed without losing information.

Actionability

Routing is concrete and unambiguous — specific paths (commands/, skills/controller.md, guidelines.md), explicit conditions ("If the user provided a Jira issue key or URL, execute the /ingest phase"), and a fully specified failure path. Falls short of 'fully executable' because the instructions depend on files not present in the provided bundle, and "execute the first phase the user requests" leaves the no-input case undefined — minor gaps, matching anchor 4.

Workflow Clarity

The orchestrator's own sequence is clear with an explicit error checkpoint and feedback loop ("If a step fails or produces unexpected output... stop and report the error to the user. Do not advance to the next phase. Offer to retry the failed step or escalate"). Not 5 because the multi-phase workflow it orchestrates is never sequenced in the body — it is delegated wholesale to skills/controller.md — leaving the happy-path checkpoints implicit here.

Progressive Disclosure

On paper the structure is ideal — a lean hub with clearly signaled one-level-deep references (commands/, skills/controller.md, guidelines.md) — but none of these referenced files exist in the bundle as provided (no references/, scripts/, assets/, or any other files alongside SKILL.md), so every reference dangles and navigation cannot be completed. The organization of what is written exceeds anchor 3, but unverifiable/missing targets mean it cannot be credited as well-organized end-to-end (anchor 4).

Specificity

The description lists multiple concrete actions covering the full pipeline — "Takes a Jira [UI] Story, plans the implementation..., writes contract-based unit tests and production code via TDD, validates against the project's CI expectations, and manages review via GitHub PRs" — matching the anchor for comprehensive coverage of specific concrete actions. Not 4 because no phase of the workflow is left uncovered; ingest through publish are all named.

Completeness

Both questions are answered explicitly: the what is the full action pipeline quoted above, and the when is a concrete trigger clause — "Use when implementing [UI] stories produced by the design workflow with a ui-design document". Not 4 because the when-clause is already explicit and specific, not merely present.

Trigger Term Quality

Good natural-term coverage: "implementing [UI] stories", "UI/front-end", "unit tests", "TDD", "GitHub PRs", "ui-design document", plus the explicit slash-command list. A few natural synonyms are missing (e.g., "frontend" unhyphenated, "ticket", "issue", "component"), which fits anchor 4 rather than 5's comprehensive-synonym coverage; it clearly exceeds anchor 3's 'some relevant keywords'.

Distinctiveness Conflict Risk

It carves a clear niche — Jira [UI] stories "produced by the design workflow with a ui-design document" — with distinct triggers, so overlap risk with general coding or non-UI skills is minimal. Not 4 because the trigger conditions are narrow and unambiguous rather than leaving minor overlap risk.
