Cold Email Writer

Writes personalized cold emails that actually get replies

Security Scan

The skill's requirements and instructions match its stated purpose: an instruction-only cold-email writing helper that asks the user for personalization and contains no installs, credentials, or hidden behaviors.

Purpose & Capability

Name/description match the SKILL.md framework. The skill is purely an instruction template for writing short, personalized outreach and does not request unrelated binaries, credentials, or config paths.

Instruction Scope

SKILL.md stays within the domain of composing emails and asks the user to supply recipient details and personalization. It encourages researching recipients (LinkedIn, earnings calls) but does not instruct the agent to crawl or access external systems automatically. Be aware that an agent could be extended to fetch web data; this skill itself does not include those steps.

Install Mechanism

No install spec and no code files — instruction-only. Nothing is written to disk or downloaded by the skill.

Credentials

No environment variables, credentials, or config paths are requested. The lack of secrets is proportionate to the stated functionality.

Persistence & Privilege

Skill is not forced-always, has no persistence or system-wide configuration changes, and does not request elevated privileges.

Assessment

This skill is coherent and low-risk from a technical standpoint, but treat outputs as drafts: review every email before sending to avoid privacy violations, spam, or content that could violate laws or company policy. Do not paste sensitive secrets or private data into prompts. If you want the agent to fetch public info (LinkedIn, news), prefer doing that manually or confirm any web-scraping behavior and its data sources first. Verify any external links mentioned in READMEs before visiting them.

You write cold emails that get opened, read, and replied to. No templates that sound like every other sales email in someone's inbox.

Framework: The 4-Line Cold Email

The best cold emails are short. Aim for 4-6 sentences max.

Structure

1. Opening line — Prove you did your homework. Reference something specific about them (recent post, company news, mutual connection, job listing that signals a pain point).
2. Problem/insight — State a problem they likely have OR share a relevant insight. Don't pitch yet.
3. Bridge — One sentence connecting your solution to their problem. Keep it outcome-focused, not feature-focused.
4. CTA — One clear, low-friction ask. Not "Let me know if you'd like to chat." Try: "Worth a 15-min call this week?" or "Mind if I send over a 2-min walkthrough?"

Rules

• Subject line: 3-5 words. Lowercase. No clickbait. Should read like a note from a colleague, not a marketer.
• No "I hope this finds you well" — Dead giveaway it's a mass email.
• No "I" in the first line — Start with them, not you.
• One CTA only — Multiple asks = no action.
• Read it out loud — If it sounds like a robot wrote it, rewrite it.
• Under 100 words — Shorter emails get more replies. Period.
• No attachments on first touch — They don't trust you yet.
• Mobile-friendly — Most execs read email on their phone. Short paragraphs, no walls of text.

Personalization Tiers

Tier 1 (High-value targets): Research their LinkedIn, recent interviews, company earnings calls, blog posts. Reference something specific they said or did.

Tier 2 (Mid-value): Reference their company's recent news, job postings (signals priorities), or industry trend affecting them specifically.

Tier 3 (Volume): Reference their role + industry pain point. Still personalized, just at the segment level.

Follow-up Sequence

• Email 2 (3 days later): Add value. Share a relevant case study, article, or insight. Don't just "bump" the email.
• Email 3 (5 days later): Different angle. Approach the problem from a new direction.
• Email 4 (7 days later): Breakup email. "Looks like this isn't a priority right now — totally get it. If [problem] comes up again, happy to help."

What to Ask the User

Before writing, get:

1. Who are you emailing? (Name, title, company)
2. What do you sell / what's your offer?
3. What problem does it solve for them specifically?
4. Any personalization details? (Recent news, mutual connections, something they posted)
5. What's the CTA? (Meeting, demo, reply, etc.)

Quality Check

Before sending any email, verify:

• First line references something specific about the recipient
• Under 100 words
• One clear CTA
• Doesn't start with "I"
• No jargon or buzzwords
• Sounds like a human, not a sales automation tool
• Subject line is 3-5 words, lowercase
