cold-email-craft

cold-email-craft is a skill for Claude Code from cmj-hub/claude-cold-email. It costs 84 tokens per session (1,076 once invoked), scanned A, original, MIT.

A cold-email writing guide creates one signal-based sales email or a three-message follow-up sequence using a defined framework. A signal is a recent, public event that may reveal a business need.

In plain words
What is it for?
Use it to write or rewrite cold emails and follow-ups with a short message, a single yes-or-no request, and wording tied to a verifiable event.
Why use it?
It reduces guesswork by requiring the recipient, company, event, likely problem, value statement, and sender details before drafting.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cold-email-craft scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cold Email Craft — sub-skill

Drafts the actual email(s). Loaded by cold-email when the user wants to write or sequence outreach.

Activation

The main cold-email skill routes here when the user says any of:

  • "Write a cold email to..."
  • "Draft an outreach to..."
  • "Build a 3-touch sequence for..."
  • "Follow-up to at "
  • "Rewrite this cold email"

Workflow

1. Gather the six framework variables

Required:

Variable Source Ask if missing
firstName User-provided "What's the recipient's first name?"
role User-provided or LinkedIn "What's their role?"
company User-provided "Which company?"
signal Public, recent, verifiable "What did they just do publicly? (Job post, funding, launch, hire, content)"
pain What the signal implies operationally "What does that signal imply about their pipeline / motion / stack?"
evp One-line value prop "What's your one-line EVP for this segment? (≤22 words)"
senderName User "Who are you signing as?"

Do not fabricate. If any are missing, ask. Never assume role, company, or signal — wrong assumptions kill cold email.

2. Validate the framework

Before generating, validate:

  • Signal is something they DID, not who they ARE. If user provides "VP of Marketing at Series B SaaS", push back: "That's a demographic, not a signal. What did they post/announce/ship in the last 30 days?"
  • Pain uses their language, not yours. No "synergy" / "optimize" / "leverage".
  • EVP is ≤22 words, has one specific outcome, one tradeoff.

3. Generate

Use the canonical template from references/copy-frameworks.md:

Subject: <see references/subject-line-patterns.md>

{firstName} —

<Quote the signal verbatim, 1 sentence.>

<Pain in their language, 1 sentence.>

<EVP, ≤22 words.>

<Binary CTA, time-bound.>

— {senderName}

4. Self-check against constraints

After generating, verify:

  • Total word count <90
  • No banned openers ("Hope you're well", "Just wanted to")
  • No banned closes ("Let me know your thoughts", "Happy to chat")
  • Binary CTA (yes/no answerable)
  • Signal is quoted verbatim (not paraphrased)
  • Pain uses recipient's language
  • EVP ≤22 words
  • Subject ≤7 words, no clickbait
