Conciseness

The body is mostly dense, project-specific instruction with no padding about concepts Claude already knows, but several rules are stated repeatedly: the tenant/org-scoped offline-read filter appears in Mobile UI, Offline Sync, Project-Specific Rules, the Self-Review Checklist, and Anti-Patterns; the 'never edit a generated sync schema file' rule appears twice; role-derivation rules appear three times. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than 4, where over-explanation would only be minor.

Actionability

Fully copy-paste ready: exact save paths ('docs/superpowers/specs/<STORY-KEY>.md'), a branch name, a PR title, an executable bash block ('bash ${CLAUDE_PLUGIN_ROOT}/scripts/jira-site-guard.sh || exit 1', 'acli jira workitem comment create ...'), a complete markdown spec template with tables and fully-typed TypeScript interface examples, and a machine-checkable self-review gate. This matches 'fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

The flow is discernible and guarded: a hard precondition ('If you did not successfully fetch the Jira ticket before calling this skill, STOP'), an announced start, a template to fill, a self-review gate ('before saving -> every item in gate must hold'), and post-merge steps. It is not 5 because the sequence is never presented as an ordered step list — the reader must infer the order of Guard → template → checklist → save → PR → comment from section layout — and there is no explicit retry/recovery loop if the gate fails.

Progressive Disclosure

Headings are clear, but no bundle files exist (no references/, scripts/, or assets/ directories) while the body leans on external pointers that are neither verifiable nor clearly signaled as navigation: 'plugins/sdlc/refs/artifact-encoding.md' is cited in one prose line, '${CLAUDE_PLUGIN_ROOT}/refs/design-references.md' in another, and 'project-context' is invoked repeatedly without ever being resolved to a file. The ~170-line inlined spec template is content that could live in a separate template file. This matches 'some structure but could be better organized; references present but not clearly signaled'.

Specificity

The description names the domain ('technical design spec for a feature or Jira story') and enumerates concrete coverage areas ('data model, API surface, permissions, offline-sync rules where applicable, and web/mobile UI'), which matches the anchor 'lists several specific actions; minor gaps in coverage'. It falls short of 5 because the concrete actions themselves are limited to producing and enforcing structure, rather than a comprehensive set of distinct actions.

Completeness

Both 'what' and 'when' are explicit: 'Use when producing a technical design spec for a feature or Jira story' gives concrete triggers, and 'Enforces consistent spec structure covering data model, API surface, permissions, offline-sync rules... and web/mobile UI' states what it does. 'Run before writing-plans' additionally clarifies pipeline position, matching the anchor for clearly and explicitly answering both what AND when.

Trigger Term Quality

Natural trigger phrases are present: 'producing a technical design spec', 'feature', 'Jira story', 'writing-plans' — terms a user would plausibly say. Not 5 because common synonyms and variations ('specification', 'tech design doc', 'TDD', 'design document') are missing; not 3 since the primary natural phrases users actually use are covered.

Distinctiveness Conflict Risk

A clear niche is stated — technical design specs for features/Jira stories — and it distinguishes itself from the closely related skill by saying 'Run before writing-plans', which minimizes overlap risk. It is not 4 because the trigger phrases ('technical design spec', 'Jira story') are specific enough that it would not naturally fire for unrelated skills.
