Lists multiple specific concrete actions: 'pre-launch verification, go-live procedures, DNS cutover, post-launch monitoring, and rollback procedures.' These are distinct, actionable phases of a launch process.

Clearly answers both 'what' (plan and execute a launch runbook covering specific phases) and 'when' (explicit 'Use this skill whenever...' clause with detailed trigger scenarios and an explicit list of trigger terms).

Excellent coverage of natural trigger terms users would say: 'launch runbook, go-live, launch day, DNS cutover, deploy to production, site launch, product launch, cutover plan, launch checklist, deployment procedure.' Also includes the edge case of implicit triggers when a launch is approaching.

Highly distinctive niche focused on launch runbooks and go-live coordination. The specific terms like 'DNS cutover,' 'rollback procedures,' and 'launch day' clearly distinguish this from general deployment or project management skills.

The content is generally well-organized and avoids explaining basic concepts, but it's verbose in places—the roles table, failure patterns, and communication plan sections contain guidance that is fairly generic project management knowledge Claude already possesses. The 'When to use' / 'When NOT to use' sections and 'Required inputs' add some padding. Could be tightened by ~30%.

The skill provides structured checklists, timelines, and role definitions, which is good. However, it's entirely descriptive—no concrete commands, no executable code snippets, no specific tool invocations. Steps like 'Deploy code to production' and 'Run smoke tests' remain abstract. The cutover sequence describes what each step *should have* but doesn't provide a concrete example of a filled-out step with actual commands.

The four-phase framework is clearly sequenced with explicit time markers (T-30, T-7, T-1, T-0, T+1hr, T+24hr, T+7d). Verification checkpoints are built into each phase, rollback criteria are pre-defined with decision authority, and the cutover sequence explicitly requires verification after each step before proceeding. The workflow section at the end provides a clear summary sequence including testing rollback and tabletop exercises.

The skill references a template file at `references/runbook-template.md` which is appropriate, but the bundle doesn't actually contain this file. The main SKILL.md is quite long (~200+ lines) and some sections (failure patterns, detailed communication plan, full roles table) could be split into reference files. The structure is reasonable but the content-to-reference ratio is skewed toward inline.
