Conciseness

Mostly efficient — tables, concrete commands, and templates rather than prose — but there is real duplication: the "Test Options (--test)" table repeats the "Mandatory Test Checklist" table's option/reference mapping, and "Multi-Environment Support" restates what the Usage examples already show. Not 2 because there is no explanatory padding of concepts Claude already knows; not 4 because the duplicated tables and the ~70-line inline browser section could be meaningfully tightened.

Actionability

Highly executable throughout: copy-paste `gh pr view`/`gh pr list` queries with expected output shape, a curl dev-server restart-and-poll loop, route tables with pass criteria, and report templates. Not 5 because the `smoke test` entry command itself is never defined or sourced — where it comes from (a script, CLI, or harness) is unstated, leaving a gap in the most important command.

Workflow Clarity

Clear sequenced workflow with explicit validation checkpoints and feedback loops: verify the dev server is alive before opening the browser, restart-and-poll for readiness, a fallback when networkidle times out, gating rules ("Do not create the alpha smoke-test project until the automatic alpha publish workflow has completed"), a partial-publish recovery branch, and a mandatory checklist with per-test read-execute-mark progression and explicit blocker/reporting rules. Matches the top anchor including checklist and error-recovery loops.

Progressive Disclosure

Verified against the actual bundle: all referenced paths exist (all 12 references/tests/*.md, every references/*.md named in the body and References table, and the 3 scripts/*.sh), references are one level deep, and the body instructs staying in SKILL.md until the workflow branches. Not 5 because the "Local Studio Browser Smoke" section (routes table, expectations, report template) is detailed inline content that belongs in a reference file, adding ~70 lines to the overview.

Specificity

"Smoke test Mastra projects locally or deploy to staging/production" and "Tests Studio UI, agents, tools, workflows, traces, memory" list several concrete, specific capabilities. Falls short of 5 because "and more" hedges coverage and "Supports both local development and cloud deployments" restates the first sentence rather than adding a capability; it is clearly above 3 (which expects only 1-2 concrete actions).

Completeness

The "what" is clear (smoke tests Mastra projects across the listed feature areas), but there is no "Use when..." clause or any equivalent explicit trigger guidance — "Supports both local development and cloud deployments" describes capability, not when to invoke the skill. Per the rubric guideline, a missing 'Use when' clause caps completeness at 3; it is not 2 because the "what" is concrete and specific.

Trigger Term Quality

Includes natural terms users would say: "smoke test", "Mastra", "deploy", "staging", "production", "Studio UI", "agents", "tools", "workflows", "traces", "memory". Not 5 because there are no synonyms or common variations (e.g., "verify", "check", "regression test") beyond the single "smoke test" phrasing; clearly above 3's "some relevant keywords but missing variations".

Distinctiveness Conflict Risk

Clear niche: "Mastra" plus "Studio UI", "agents", "workflows", "traces" are framework-specific triggers with minimal overlap risk against generic testing or deployment skills. Nothing in the description would plausibly route a non-Mastra task to it.
