emails

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.

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured instruction skill: dense, number-backed guidance, concrete output templates, and exemplary progressive disclosure into three clearly signaled reference files. Weaker spots are a placeholder Metrics Plan section, a few generic-knowledge bullets, and the lack of a single explicit ordered workflow.

Suggestions

Replace the placeholder "Metrics Plan — What to measure and benchmarks" with concrete metric names and benchmark ranges per sequence type (e.g., open rate, click-through rate, unsubscribe rate, reply rate with typical thresholds), or move them into a references file and link it.

Trim bullets that restate knowledge Claude already has ("Read it out loud—does it sound human?", "Quality > frequency", "Mobile-first (most read on phone)") to cut tokens without losing guidance.

State the end-to-end process as one ordered list (read product-marketing context → ask the task-specific questions → choose sequence type and length → draft each email per the output format → define the metrics plan) so the implicit flow becomes explicit.

DimensionReasoningScore

Conciseness

The body is almost entirely tight bullets with concrete numbers ("Welcome: 3-7 emails," "40-60 characters," "~90-140 characters"), but a handful of bullets restate generic copywriting wisdom Claude already knows ("Read it out loud—does it sound human?", "Quality > frequency", "Mobile-first (most read on phone)"). Efficient with minor trimmable instances — anchor 4 rather than 5; not 3 because padding is sparse and there is no explanatory prose.

4 / 5

Actionability

Highly actionable for an instruction-only skill: per-sequence blueprints with per-email purposes and day-level timing ("6. Core feature highlight (day 9-11)"), subject-line patterns with worked examples ("[First name], your [thing] is ready"), and a field-by-field output template ("Email [#]: [Name/Purpose] / Send: [Timing] / Subject: ..."). Not a 5 because "Metrics Plan: What to measure and benchmarks" is a placeholder naming no actual metrics or benchmark values.

4 / 5

Workflow Clarity

A coherent implicit flow exists: Initial Assessment (with an explicit ordering rule — "read it before asking questions" for product-marketing context) → strategy selection → per-email drafting via the output format → metrics plan. Sequence is clear with the context-gathering checkpoint made explicit; minor gaps because the end-to-end process is never stated as one ordered list and the final review/metrics step is underspecified. Not 3 — checkpoints like context-first and task-specific questions are present; not 5 — no explicit error-recovery or review loop.

4 / 5

Progressive Disclosure

SKILL.md is a genuine overview: detailed templates, email-type reference, and copy guidelines are split into three real one-level-deep bundle files, each clearly signaled at the natural point ("For detailed templates: See [references/sequence-templates.md](references/sequence-templates.md)" and likewise for email-types.md and copy-guidelines.md), all of which exist in references/. Navigation is easy and nothing is deeply nested.

Description

95%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete capability statement, an explicit and richly synonymed trigger list covering natural user phrasings, and explicit routing boundaries to neighboring skills. The only weakness is that the capability verbs (create/optimize) stay high-level relative to the concrete deliverable types named.

DimensionReasoningScore

Specificity

"create or optimize an email sequence, drip campaign, automated email flow, or lifecycle email program" lists several specific deliverable types with two concrete actions (create, optimize), but the actions themselves are generic and the description never states what the skill produces (full sequence designs with copy, timing, and metrics). Not a 5 because coverage of actions is narrow; not a 3 because it names multiple concrete sequence-type capabilities beyond 1-2.

4 / 5

Completeness

Explicitly answers what ("create or optimize an email sequence, drip campaign, automated email flow, or lifecycle email program") and when ("When the user wants to..." plus "Also use when the user mentions..." plus "Use this for any multi-email automated flow") with concrete trigger phrases. Matches the anchor-5 example structure exactly.

5 / 5

Trigger Term Quality

Fourteen natural quoted phrases including synonyms and user-voice variants ("email sequence," "drip campaign," "welcome series," "email cadence," "what emails should I send") give comprehensive coverage of how a user would naturally ask for this. Clearly matches the top anchor, including the colloquial question form.

5 / 5

Distinctiveness Conflict Risk

Clear niche (multi-email automated flows) with explicit boundary disambiguation: "For cold outreach emails, see cold-email. For in-app onboarding, see onboarding." Minimal conflict risk — the adjacent skills are named and their scopes carved out.
