Six skills, one /cold command. ICP builder, lead sourcing, drafter, sender, reply triage, reporter. Reads a portable cold.md spec from your repo. Backed by FoxReach for sending.
Not another cold-email skill. The other Claude Code cold-email skills on the market draft messages. That's step 3 of a six-step loop. cold.md is the whole loop.
curl -fsSL https://cold.md/install | bashThat installs the full cold-md plugin (all 6 skills, the /cold router) to ~/.claude/plugins/cold-md/. Pass --skills-only to skip the plugin and get the open skills only. Pass --scaffold to also drop cold.md + icp.md templates in your current repo.
/cold icp https://your-site.com # Step 1: who - builds icp.md
/cold leads --count 100 # Step 2: prospects - writes leads.csv (v0.2)

| 01 | cold-icp |
Build icp.md from a URL or Q&A |
Live | Nothing |
| 02 | cold-leads |
Source leads matching icp.md into leads.csv |
Stub (v0.2) | FoxReach API key |
| 03 | cold-draft |
Draft openers, bumps, breakups from cold.md |
Live | Nothing |
| 04 | cold-send |
Queue campaign via FoxReach with safety checks | Stub (v0.2) | FoxReach API key |
| 05 | cold-triage |
Sort inbound replies, draft responses | Stub (v0.2) | FoxReach API key |
| 06 | cold-report |
Daily or weekly digest, cron-ready | Live | FoxReach API key |
Stubs are intentional. They define a stable contract so you can wire your own tooling today; the full implementation ships in v0.2.
./cold.md # voice, sequence, proof, banned - what the skills write
./icp.md # audience, disqualifiers, qualification checklist - who they target
Both live at your repo root. Both are plain markdown. Both are portable across vendors.
# My Product - cold.md
## Identity - who's sending
## Audience - ICP + disqualifiers
## Value - the offer, in one sentence
## Voice - dos and don'ts, obeyed verbatim
## Proof - facts the agent may cite
## Sequence - opener, bump, breakup slots
## Objections - preferred replies to pushbacks
## Banned - phrases that never appear
Spec: spec/cold-md-v0.md. Also published at cold.md.
| Single cold-email skill | cold.md suite |
|---|---|
| Writes copy when asked | Owns every step: ICP → leads → draft → send → triage → report |
| No ICP, no sending, no triage | All six, each callable independently |
| Config lives in the prompt | Config lives in cold.md + icp.md in your repo |
| Every project restarts from scratch | Files travel with your team |
| Vendor-locked to whichever LLM | Vendor-neutral spec. Swap backends without rewriting. |
The skills that send, triage, or report need an API key:
export FOXREACH_API_KEY=fr_...Free tier: https://foxreach.io/signup.
cold-report is designed to run unattended. Two recommended paths:
(a) FoxReach dashboard - schedule digest in Notifications. Posts to Slack/email. Zero local setup.
(b) Claude Code /schedule skill - for power users who keep Claude Code running:
/schedule "0 9 * * 1" "cold report weekly"spec/ The cold.md file spec. Versioned.
skills/ The six standalone skills (each installable solo).
plugin/cold-md/ The Claude Code plugin that bundles all six + the /cold router.
examples/ Sample cold.md files (minimal starter + the real FoxReach one).
site/ Next.js site at cold.md.
assets/ Cover image, brand.
memory/ Architecture, decisions, changelog.
The spec is the product. Every change to spec/ is a commercial decision - open an issue first. New skills, examples, docs, and implementations: PRs welcome. Especially interested in other backend implementations (Smartlead plugin? Mailcoach plugin? PR it).
The team at FoxReach. Cold email infrastructure that doesn't torch your domain.
