Write high-converting cover letters and pain letters for job applications. Use when the user needs to write a cover letter, pain letter, or application message for a specific company or role. Follows frameworks from YC partners, DHH, Liz Ryan (Forbes), Austin Belcak, and a16z — focused on company research, pain hypotheses, and quantified evidence. NOT for cold emails (use cold-email skill instead).
Write cover letters that prove effort, not just interest.
Every credible source converges on one insight: effort is the filter. Out of 1,000+ applicants, only ~5 put in real work (Sahil Lavingia, DHH both cite this exact number). The cover letter isn't about writing — it's about proving you care enough to do homework.
NOT this skill:
Before writing, gather from the user:
Always recommend the highest tier the user is willing to execute:
| Tier | Type | Conversion |
|---|---|---|
| 1 | Portfolio proof — build something, send a link + 1-2 page write-up | Highest |
| 2 | Pain letter — Liz Ryan framework, physical mail to hiring manager | ~25% callback |
| 3 | Targeted email cover letter — 3 paragraphs, <200 words | Table stakes |
Generic cover letters → immediate discard. Any of the three tiers beats volume.
Four paragraphs. One page max. Mail physical copy if possible.
Hook — Timely company accomplishment (<6 months old)
"I was glad to see Acme voted Austin's fastest-growing startup this quarter."
Pain Hypothesis — Educated guess about their biggest challenge
"Given your 30% annual growth, your engineering team must be under pressure to ship faster while maintaining quality."
Dragon-Slaying Story — Proof you solved similar pain, with numbers
"When I was at Stripe, we grew from 3 to 12 engineers. I built the CI/CD pipeline that cut deploy time from 4 hours to 15 minutes."
Soft CTA — Low-friction ask, never pushy
"If you have a moment to chat about scaling your engineering team, I'd be glad to connect."
Rule: Never say "I know your problem." Always frame as a hypothesis.
Every unnecessary word subtracts from impact.
Structure every bullet and every achievement:
