cold-email

Write B2B cold emails and follow-up sequences that get replies. Use when the user wants to write cold outreach emails, prospecting emails, cold email campaigns, sales development emails, or SDR emails. Also use when the user mentions "cold outreach," "prospecting email," "outbound email," "email to leads," "reach out to prospects," "sales email," "follow-up email sequence," "nobody's replying to my emails," or "how do I write a cold email." Covers subject lines, opening lines, body copy, CTAs, personalization, and multi-touch follow-up sequences. For warm/lifecycle email sequences, see emails. For sales collateral beyond emails, see sales-enablement.

Quality

Content

86%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.

The body is a well-structured, actionable guide that defers detail to real reference files and avoids explaining concepts Claude already knows. Its only weakness is minor redundancy between the 'What it should NOT sound like' and 'What to Avoid' sections.

Suggestions

Merge the 'What it should NOT sound like' list into the 'What to Avoid' section to remove duplicated items (e.g., 'I hope this email finds you well' and AI-pattern tells appear in both).

Tighten the Quality Check from a soft gut-check into an explicit pass/fail checklist with a 'rewrite and re-check' retry step so the validation loop is unambiguous.

Dimension	Reasoning	Score
Conciseness	Lean and assumes Claude's competence — no padding explaining what cold email is — but 'What it should NOT sound like' and 'What to Avoid' overlap (e.g., 'I hope this email finds you well' / AI-pattern tells appear in both), a minor instance of over-explanation that could be trimmed.	4 / 5
Actionability	Highly actionable instruction-only guidance: concrete framework templates (Observation → Problem → Proof → Ask) with examples, specific subject-line rules (2-4 words, lowercase), explicit CTA phrasing ('Worth exploring?'), and follow-up cadence (3-5 emails), covering common cases.	5 / 5
Workflow Clarity	Clear sequence (check product-marketing context → understand the 5 situation inputs → apply principles → quality-check gut list) with a closing validation checklist, but the checkpoint is a soft gut-check rather than a hard validate/retry loop; not a destructive or batch skill so the cap-3 rule does not apply.	4 / 5
Progressive Disclosure	SKILL.md is a clear overview with well-signaled one-level-deep references — personalization.md, frameworks.md, subject-lines.md, follow-up-sequences.md, benchmarks.md — all confirmed present in references/, and a dedicated 'Data & Benchmarks' section organizes navigation.	5 / 5

Description

100%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.

The description is exemplary: it states concrete capabilities, provides extensive natural trigger terms, answers both what and when explicitly, and disambiguates from adjacent skills with boundary guidance. Voice is third person, matching the rubric requirement.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete components — 'Write B2B cold emails and follow-up sequences' plus 'subject lines, opening lines, body copy, CTAs, personalization, and multi-touch follow-up sequences' — giving comprehensive coverage of the skill's actions.	5 / 5
Completeness	Explicitly answers both what ('Write B2B cold emails and follow-up sequences that get replies') and when ('Use when the user wants to write cold outreach emails...') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Comprehensive natural synonyms and phrases users actually say: 'cold outreach,' 'prospecting email,' 'outbound email,' 'email to leads,' 'reach out to prospects,' 'nobody's replying to my emails,' and 'how do I write a cold email,' including the SDR variant.	5 / 5
Distinctiveness Conflict Risk	Clear B2B cold-outreach niche with distinct triggers and explicit boundary routing ('For warm/lifecycle email sequences, see emails. For sales collateral beyond emails, see sales-enablement.'), minimizing conflict risk.	5 / 5
	Total	20 / 20 Passed
