Conciseness

The body is lean and directive with no concept explanations or padding — every line instructs. Not 5 because the Rules section restates workflow content already covered ("Delegate the audit to launch-readiness... don't re-implement" duplicates step 2; "re-assess after applying" duplicates step 6; the confirm-before-change rule duplicates step 5).

Actionability

Steps name concrete delegate targets and conditions: "ASSESS via `launch-readiness`", "run `check-updates` against the pinned `@convex-dev/*` components", "if the readiness report flagged an observability gap (no prod error capture), offer to install `sentinel`". Not 5 because "dispatching each fix to its fixCapability" and the `sentinel` install have no invocation detail; not 3 because the guidance is mostly executable via named skills with only minor gaps.

Workflow Clarity

Six clearly sequenced steps with explicit checkpoints: "apply only on explicit confirmation" and "After applying, re-run the launch-readiness assessment and show the score delta" provide a validation loop for risky prod changes. Not 5 because there is no error-recovery branch (what to do if a fix fails or the score regresses) and no rollback guidance for changes to someone's existing app.

Progressive Disclosure

The skill is under 50 lines with no bundle files (no references/, scripts/, or assets/ exist); "## Workflow" and "## Rules" are well-organized sections, nothing that belongs in a separate file is inlined, and cross-skill references (launch-readiness, check-updates, sentinel) are clearly signaled — fitting the short-skill exception for a score of 5.

Specificity

"Audit and optimize an existing Convex app" combined with the four named areas "security, scale, upgrades, observability" lists several specific actions with minor gaps. Not 5 because the focus areas are categories rather than fully concrete actions ("scale" does not state what is actually done), and not 3 because it goes beyond 1-2 actions.

Completeness

The "what" is clear ("Audit and optimize an existing Convex app: security, scale, upgrades, observability") but there is no "Use when..." clause or equivalent explicit trigger guidance — "an existing Convex app" only weakly implies when, capping completeness at 3 per the judging guidelines.

Trigger Term Quality

"Convex", "audit", "security", "upgrades", and "observability" are terms a user would naturally say when needing this skill. Not 5 because common synonyms such as "review", "performance", and "production" are missing; not 3 because coverage is good and includes the distinctive niche term.

Distinctiveness Conflict Risk

"Convex app" names a clear niche with distinct triggers; minimal conflict risk with any non-Convex skill. Not 4 because even closely related skills (security review, dependency upgrades) are disambiguated by the Convex qualifier.
