Names the domain (email sequences/drip campaigns) and mentions actions like 'create or optimize,' but doesn't list specific concrete actions like 'write subject lines, set timing delays, segment audiences, A/B test content.'

Clearly answers both what (create/optimize email sequences and drip campaigns) and when (explicit 'Use when' equivalent with comprehensive trigger terms). Also includes helpful disambiguation pointing to another skill for in-app onboarding.

Excellent coverage of natural terms users would say: 'email sequence,' 'drip campaign,' 'nurture sequence,' 'onboarding emails,' 'welcome sequence,' 're-engagement emails,' 'email automation,' 'lifecycle emails' - these are all terms users naturally use.

Clear niche focused specifically on email sequences and automation. The explicit disambiguation ('For in-app onboarding, see onboarding-cro') shows awareness of potential conflicts and actively prevents them.

Generally efficient but includes some unnecessary framing ('You are an expert...') and explanatory content Claude already knows (basic email marketing concepts). The lists are comprehensive but could be tighter in places.

Provides good structural templates and timing guidelines, but lacks executable code examples for email platform integrations. The output format templates are helpful but the actual email copy examples are missing - it describes what to include rather than showing complete examples.

Clear sequencing with explicit timing, triggers, and exit conditions. The sequence types have well-defined steps with day-by-day progression. The output format section provides a clear checklist structure for deliverables.

Excellent structure with clear overview in main file and well-signaled one-level-deep references to detailed templates (references/sequence-templates.md, references/email-types.md, references/copy-guidelines.md). Tool integrations appropriately linked to external guides.
