cold-email

cold-email is a skill for Claude Code, Codex from androoAGI/starnet. It costs 47 tokens per session (2,388 once invoked), scanned A, original, MIT.

A cold-email skill drafts first-contact business emails and follow-ups for people who have not previously engaged with you. The drafts use only personal details that were actually researched and opened from a source.

In plain words
What is it for?
Use it to draft business-to-business outreach, follow-up sequences, and rewrites of emails that sound too much like a sales pitch.
Why use it?
It helps avoid generic outreach and unsupported personalization. A single clear request also makes it easier for the recipient to understand how to respond.

About the project

StarNet is a local-first desktop harness for creating AI agents and arranging them in a pixel-art space station whose layout represents their capabilities, permissions, and workflow. It lets people run real model calls and tools through multiple bounded agents, using their own provider keys or accounts and optionally messaging the station through chat services. The catalogue entries are skills that extend or support work performed by StarNet agents.

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 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 12d 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.

Cold Email

Write business-to-business cold emails and follow-ups that read as if a sharp, thoughtful person wrote them, not a sales machine working through a template. The bar: drafts only, one clear ask per email, and every personal detail traceable to a source you opened in this run.

When to use

  • "Write a cold email to X." "Draft outreach for this list." "Nobody replies to my emails."
  • A follow-up sequence for prospects who have not answered.
  • A rewrite of an outreach email that reads like a pitch.

Not for emails to people who already signed up or bought (email-sequence), and not for finding who to write to (lead-scouting, which comes first).

Method

  1. Get the brief. Five things: who you are writing to (role, company, why them); the outcome wanted (a reply, an introduction, a call); the value (the specific problem solved for people like them); the proof (a real result, customer or credential, supplied by the Commander); any signals already known. Look for a product brief in the workspace with fs.search first. Work with what you have. Do not block on a missing input; note what would make the email stronger.
  2. Research, and keep a source table. For individual-level personalisation, read the company's site, news or press page and careers page, and the person's public writing or talks (web_search, then web_fetch; browser.navigate and browser.get_text for pages that need a real browser). Record each usable signal in a table: the detail, the URL, the date on the page, and the exact words you saw. Profile pages behind a login stay closed; use only what the Commander pastes from them.
  3. Choose the personalisation level honestly. Use the four levels below. With no verified signal about the person, write at role or industry level and say that you did. Never dress a guess up as an observation.
  4. Choose a shape. One of the four common shapes below, or a framework from references/frameworks.md (included at the end of this skill), or freeform when the email flows without one.
  5. Write the first email. Aim for 25 to 75 words. Follow the principles and the voice notes.
  6. Write the subject line. Two or three options.
  7. Write the follow-ups. Three to five emails in total, each with a new angle. Cadence, angles and the last "breakup" email are in references/follow-ups-and-subject-lines.md (included at the end of this skill).
  8. Run the quality check and fix what fails.
  9. Deliver drafts and stop. Save the drafts, the source table and the list of gaps with fs.write, name the file with deliverable_note, and hand over. The Commander sends.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
