Conciseness

The body is efficient and assumes Claude's competence — no explanation of what deploys or HTTP statuses are; commands and templates dominate. Minor trimming is possible: the Usage section repeats the two modes already stated up top, and the 'Output format' section mostly points back to Phase 5 while duplicating the inline alert example, which is why it is not level 5.

Actionability

Mostly executable guidance: concrete curl/jq pipelines, a baseline JSON schema, an alert-condition table with exact thresholds, and copy-paste report templates. Minor gaps keep it below 5: the PAGES array is used in the monitoring loop but never populated, Phase 6 copies '.canary/reports/latest-snapshot.json' which is never created, and the '--quick' flag appears in Usage with no implementing instructions.

Workflow Clarity

A clear six-phase sequence with most checkpoints present: explicit STOP after baseline capture, baseline-diff comparison logic, transient tolerance (alert only on 2+ consecutive checks), and an alert decision menu (A-D) acting as a feedback loop. Not level 5 because argument parsing for --duration/--pages/--quick is only gestured at ('Parse the user's arguments') and the Phase 5-to-6 handoff references a file that no phase writes.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), and the single-file body is well organized into clearly headed phases with consistent templates. Structure is good with only minor organization gaps (the 'Output format' section redundantly re-references Phase 5 content instead of consolidating), so it sits at level 4 rather than the well-signaled multi-file ideal of level 5 or the inlined-wall-of-text pattern of level 2.

Specificity

The description names the domain ("Post-deploy monitoring") and 1-2 concrete actions ("watch production", "alert on regressions"), matching the level-3 anchor. It is not level 4 because additional concrete capabilities of the skill (baseline capture, health reporting) are not listed.

Completeness

The 'what' is clear (watch production after a deploy, alert on regressions), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. The 'when' is only weakly implied by the phrase "after a deploy".

Trigger Term Quality

Natural terms like "post-deploy", "monitoring", "production", "deploy", and "regressions" give good keyword coverage a user would plausibly say. It falls short of level 5 because common synonyms such as "canary", "smoke test", "rollout", or "health check" are absent.

Distinctiveness Conflict Risk

The niche is mostly distinct — post-deploy regression watching is a specific trigger context unlikely to fire for unrelated skills. Minor overlap risk remains with general monitoring, logging, or uptime-checking skills, keeping it below level 5.
