Lists multiple specific concrete actions: 'set up measurement and tracking,' 'run post-launch retros with data,' 'build a launch analytics system,' plus details like 'UTM conventions, per-tier KPIs, benchmark expectations, and retro frameworks.'

Clearly answers both 'what' (set up measurement, run retros, build analytics system, UTM conventions, KPIs, benchmarks, retro frameworks) and 'when' with an explicit 'Use this skill whenever...' clause plus additional trigger phrases.

Excellent coverage of natural trigger terms including 'track a launch,' 'set up UTM parameters,' 'measure launch performance,' 'run a launch retro,' 'analyze launch results,' 'build a dashboard for a product release,' and natural-language phrases like 'how do we know if the launch worked' and 'what should we track for this launch.'

Highly distinctive niche focused specifically on product launch measurement and analytics. The combination of launch-specific tracking, UTMs, launch retros, and per-tier KPIs makes it clearly distinguishable from general analytics or general product management skills.

The skill is generally well-structured but includes some unnecessary framing ('Without consistent measurement, launches are guesswork. With it, each launch informs the next.') and explanatory text that Claude doesn't need ('UTM parameters track where traffic comes from'). The benchmark tables and KPI tables are useful reference material but the surrounding prose could be tighter.

The skill provides concrete UTM examples, event tables, benchmark numbers, and retro frameworks, which are all useful. However, it lacks executable code or commands — there are no scripts for setting up dashboards, no concrete analytics platform configurations, no actual spreadsheet templates. It's more of a strategic playbook than a step-by-step executable guide.

The skill presents a clear chronological workflow: pre-launch setup → launch day monitoring → post-launch retro → building launch history. Each phase has explicit steps, the retro has a defined timeline (5-7 days), and there are clear 'do/don't' guidelines for launch day. The retro section includes a feedback loop (retro output feeds into checklist updates for future launches).

The companion skills section at the bottom provides clear cross-references to related skills, which is good. However, the skill itself is quite long (~200 lines) with extensive inline tables and benchmarks that could be split into reference files. There are no bundle files to support this, and the KPI tables by tier and benchmark expectations could live in separate reference documents.
