email-sequence
When the user wants to create or optimize an email sequence, drip campaign, automated email flow, or lifecycle email program. Also use when the user mentions "email sequence," "drip campaign," "nurture sequence," "onboarding emails," "welcome sequence," "re-engagement emails," "email automation," "lifecycle emails," "trigger-based emails," "email funnel," "email workflow," "what emails should I send," "welcome series," or "email cadence." Use this for any multi-email automated flow. For cold outreach emails, see cold-email. For in-app onboarding, see onboarding-cro.

Discovery
89%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong description with excellent trigger term coverage and explicit guidance on when to use it versus related skills. The main weakness is that the 'what' portion could be more specific about concrete actions beyond 'create or optimize.' The cross-references to related skills are a notable strength for disambiguation.
Suggestions
Add specific concrete actions to the beginning, such as 'Designs email sequence strategy, writes email copy, determines optimal timing and cadence, segments audiences for automated flows.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description names the domain (email sequences, drip campaigns, automated flows) and mentions 'create or optimize' as actions, but lacks specific concrete actions like 'write subject lines, schedule timing, segment audiences, A/B test content.' | 2 / 3 |
Completeness | Clearly answers both what (create/optimize email sequences, drip campaigns, automated flows) and when with explicit 'Use when' guidance and extensive trigger terms. Also includes helpful cross-references to related skills. | 3 / 3 |
Trigger Term Quality | 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,' 'email funnel,' 'what emails should I send,' and more variations. | 3 / 3 |
Distinctiveness Conflict Risk | Very clear niche focused on multi-email automated flows with explicit boundary-setting: 'For cold outreach emails, see cold-email. For in-app onboarding, see onboarding-cro.' This actively prevents conflicts with related skills. | 3 / 3 |

Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured, actionable skill for email sequence design. Its strengths are concrete guidance (specific timings, email counts, output formats) and excellent progressive disclosure with clear references to supporting files. The main weakness is moderate verbosity—some explanatory content could be trimmed since Claude understands email marketing fundamentals.
Suggestions
Remove the introductory sentence 'You are an expert in email marketing...' and the goal statement—Claude knows its role from context
Trim 'Core Principles' section to bullet points only, removing explanatory sub-bullets that state the obvious (e.g., 'Don't try to do everything')
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary explanation (e.g., 'Your goal is to create email sequences that nurture relationships' is obvious from context). Some sections like 'Core Principles' explain concepts Claude likely knows. Could be tightened by 20-30%. | 2 / 3 |
Actionability | Provides highly concrete guidance with specific email counts, timing recommendations, subject line patterns, word count ranges, and clear output format templates. The structured output format with exact fields makes this copy-paste ready for implementation. | 3 / 3 |
Workflow Clarity | Clear sequencing throughout: Initial Assessment → Core Principles → Strategy → Sequence Types → Output Format. Each sequence type has explicit timing (day 1, day 2-3, etc.) and clear progression. Exit conditions and triggers are explicitly called out in the output format. | 3 / 3 |
Progressive Disclosure | Excellent structure with clear one-level-deep references to detailed content (references/sequence-templates.md, references/copy-guidelines.md, references/email-types.md, tools registry). Main skill provides overview while pointing to specific files for depth. Related skills section aids navigation. | 3 / 3 |
