10 Claude skills every AI startup founder should install

If you're building a startup with two engineers, three product people, and a lot of AI tooling, the difference between "we ship fast" and "we ship slow" is mostly your prompt hygiene. Skills (SKILL.md files) are the cheapest way to lock in that hygiene across your team. Here are the 10 that have saved me the most hours. 1. pr-reviewer-pro ------------------- **What it does:** Reviews pull requests against your team's coding standards, catches missing tests, flags security issues, and writes a structured review comment. **Why founders care:** Code review is the #1 productivity bottleneck on small teams. This skill compresses a 30-min review into 5 minutes of "agree/override". claude skills add pr-reviewer-pro 2. investor-update-drafter --------------------------- **What it does:** Drafts a monthly investor update from your raw inputs (MRR, key wins, asks). Uses the standard "wins / lessons / asks" structure investors expect. **Why founders care:** Investor updates are high-leverage but easy to skip when you're heads-down. This skill drops the activation energy to ~10 minutes. claude skills add investor-update-drafter 3. customer-interview-synthesiser ---------------------------------- **What it does:** Takes a transcript from a 30-min customer call and extracts: pain points, feature requests, willingness to pay, segment fit. Outputs a one-page summary in your team's standard format. **Why founders care:** You can't act on 50 hours of customer calls in your head. This skill turns interview audio into prioritised next-actions. claude skills add customer-interview-synthesiser 4. landing-page-copy --------------------- **What it does:** Writes B2B SaaS landing-page copy following the Webflow / Linear / Vercel pattern (problem → product → outcome → social proof). Avoids generic AI-speak. **Why founders care:** Bad landing-page copy kills conversion. The 30-min "let's draft a hero" meeting becomes a 5-min one with a real first draft to react to. claude skills add landing-page-copy 5. seo-content-optimizer -------------------------- **What it does:** Audits an existing blog post against your target keyword: structure, internal links, meta description, schema. Outputs a checklist of fixes. **Why founders care:** Content marketing is a slow-burning fire that pays out 6-18 months later. This skill makes sure the fires you do start are well-built. claude skills add seo-content-optimizer 6. job-description-builder --------------------------- **What it does:** Drafts a role description from a one-paragraph brief. Includes responsibilities, must-haves, nice-to-haves, salary band, and a "why this role matters" hook that doesn't read like a JSON-LD scrape. **Why founders care:** Hiring is high-stakes; a bad JD costs you 2 weeks of bad applicants. This skill gets you to a "post-able" draft in 15 minutes. claude skills add job-description-builder 7. legal-redliner ------------------ **What it does:** Reviews a vendor MSA, NDA, or DPA against the standard clauses and flags anything unusual: indemnity caps, IP assignment, auto-renewal, data residency. Outputs a redline-ready summary you take to your lawyer. **Why founders care:** You'll sign 30+ vendor agreements in year one. Reading every one is unrealistic; missing the one weird clause is expensive. This skill is the smoke alarm. claude skills add legal-redliner 8. user-research-survey-designer --------------------------------- **What it does:** Designs a user-research survey from your research goals. Avoids leading questions, biased framing, and survey-length bloat. Outputs Typeform / Survey Monkey-ready questions. **Why founders care:** Bad surveys produce data you can't act on. This skill is the difference between "we surveyed 500 people and learned nothing" and "we surveyed 200 and learned three sharp things". claude skills add user-research-survey-designer 9. monthly-finance-summariser ------------------------------ **What it does:** Reads your Stripe + bank exports, computes MRR / churn / ARPU / runway, and writes a one-page CFO-style summary. Doesn't replace a real CFO; does replace the manual Excel pivot table. **Why founders care:** Founders should look at finance numbers monthly. Most don't because the prep is annoying. This skill removes the prep. claude skills add monthly-finance-summariser 10. team-1on1-prepper ---------------------- **What it does:** Given the last 4 weeks of your team's commits, PR comments, and shipped projects, drafts a personalised 1:1 agenda for each direct report. Highlights wins, flags concerns, suggests questions to ask. **Why founders care:** Good 1:1s compound. Bad 1:1s waste an hour a week per report. This skill gets you to "good prep" without the prep work. claude skills add team-1on1-prepper Installing all 10 ------------------ claude skills add pr-reviewer-pro claude skills add investor-update-drafter claude skills add customer-interview-synthesiser claude skills add landing-page-copy claude skills add seo-content-optimizer claude skills add job-description-builder claude skills add legal-redliner claude skills add user-research-survey-designer claude skills add monthly-finance-summariser claude skills add team-1on1-prepper Total install time: under 90 seconds.
