Signal-anchored B2B cold email: first touch under 90 words with a binary ask, follow-ups, subject lines, spam lint, domain deliverability, send-list hygiene, reply triage, and outbound audits. Use when the user asks for a cold email, follow-up sequence, deliverability or spam check, reply scoring, or send-list cleanup. Not for give-first offers (sales-offer), picking who to contact (prospect-list), or post-opt-in email (email-sequence).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cold Email — JMC Outreach Craft Skill Comprehensive cold email orchestrator for B2B operators. Anchors every output on a Pain Signal Profile (not demographics) and forces the output into a shape you can ship. ## Preflight (every invocation) > **Scoring something pasted needs no setup.** If the operator handed you a line, post, draft, or file to score, run the scorer on it first and report the result; missing config only means some checks are skipped, so say which. Offer setup afterwards as the next step. Check whether files exist with Read or Glob, not a shell command. Run this before routing anywhere. It is what `AGENTS.md` rules 1 and 2 require. 1. Look for `brand-config.json` and `SOUL.md` in the operator's project root. Read both if present. 2. If either is missing and the operator did not pass `--no-config`, run the setup mode ([modes/setup.md](modes/setup.md)) before drafting real outreach. If `operator` or `icp` is missing, say "Run `/gtm:setup` once for the whole suite" first. Offer once; if they decline, say the output will be framework-shaped but generic. 3. If `brand-config.json` exists, sanity-check the fields the requested …

How to install
mdr add cmj-hub/claude-cold-email/cold-email@sha256:a3fb37523cb9c128The line at the top of this page pins the label git:20261019.dfd0725, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
