Conciseness

The ~20-line body is lean and assumes Claude's competence — it dispatches via "read `commands/{command}.md` and follow it" and "read `skills/controller.md` to load the workflow controller" with zero padding or explanation of concepts Claude already knows. Every token earns its place, matching the score-5 anchor.

Actionability

Guidance is mostly executable with concrete file paths and unambiguous conditionals ("If the user invoked a specific command... read `commands/{command}.md`", "If the user provided a Jira issue key or URL, execute the `/ingest` phase"), matching the score-4 anchor for an instruction-only skill. It is not 5 because "execute the first phase the user requests" leaves a gap when the user requests no phase, and per-phase specifics are delegated without any inline example of what execution looks like.

Workflow Clarity

The dispatch sequence is clear and includes an explicit validation/feedback checkpoint: "If a step fails or produces unexpected output (e.g., Jira MCP errors, network failures...), stop and report the error to the user. Do not advance to the next phase. Offer to retry the failed step or escalate." This matches the score-5 anchor (clear sequence, explicit error-recovery loop); the destructive/batch cap does not apply because the body itself performs no batch operations and includes failure handling.

Progressive Disclosure

The body is a clean overview with well-signaled, one-level-deep references — "read `commands/{command}.md`", "read `skills/controller.md`", and "For principles, hard limits, safety, quality, and escalation rules, see `guidelines.md`" — which structurally matches the score-5 anchor. However, no bundle files were provided (no references/, scripts/, assets/, commands/, skills/, or guidelines.md exist in the skill directory), so the referenced files cannot be verified to exist, keeping this at 4 rather than 5.

Specificity

The description lists five concrete, specific actions — "takes a PRD, researches the problem space, drafts a technical design document with a requirement-anchored testplan, decomposes work into Jira-ready epics and stories, and manages review via GitHub PRs" — covering the full workflow comprehensively. This matches the score-5 anchor (multiple specific concrete actions, comprehensive coverage) rather than 4, since there are no noticeable coverage gaps in what the workflow does.

Completeness

It explicitly answers both questions: "what" via the five enumerated actions and "when" via the explicit trigger clause "Use when creating design documents, researching external integrations or standards, breaking features into epics/stories, or syncing task breakdowns to Jira". This matches the score-5 anchor (both what and when with concrete trigger phrases); a 4 would require the when-clause to be less explicit, which it is not.

Trigger Term Quality

Natural user phrases like "creating design documents", "breaking features into epics/stories", and "syncing task breakdowns to Jira" give good keyword coverage, matching the score-4 anchor. It falls short of 5 because common synonyms and variations (e.g., "spec", "tech spec", "architecture", "write stories", "project breakdown") are missing; it is clearly above 3 since multiple relevant natural phrases are present.

Distinctiveness Conflict Risk

The PRD-to-Jira design niche with distinct triggers ("PRD", "Jira-ready epics and stories", "requirement-anchored testplan") is mostly distinct, matching the score-4 anchor. It is not 5 because broad triggers like "creating design documents" and "researching external integrations or standards" could overlap with general documentation, writing, or research skills; it is well above 3 given the highly specific Jira/epics/decomposition framing.
