Founder Operations in Claude: 19 Reusable Skills for Early-Stage Startups

A founder who recently exited their first startup has open-sourced a set of 19 reusable skills for early-stage startup operations, designed to be used with Claude and Claude Code for non-coding tasks. The repo, available on GitHub at github.com/firatcand/founder-skills, contains Markdown files with the exact instructions the author kept re-typing while running their own company.

What's Inside

The skills cover common founder workflows: positioning, pricing, specs, prospecting, and copy. Each skill is a Markdown file with a structured prompt that you can feed directly to Claude or Claude Code. The author describes them as “nothing fancy — Markdown files with the instructions I kept retyping. Made them for myself first.”

While the repo content isn't quoted verbatim in the source, the idea mirrors how many builders now treat LLM prompts as modular, version-controlled assets — treating prompts like code. The skills are derived from SOPs originally stored in Notion.

Why This Pattern Matters

As AI coding agents become more common in early-stage startups, teams are shifting from manual execution to prompt-driven operations. This repo exemplifies that: instead of repeating the same instructions to Claude each time, you pull a Markdown file containing the full context, constraints, and output format for a given task — positioning, pricing analysis, or prospecting email copy.

The author is also curious about what skills other developers reuse, asking: “If you reuse a lot of skills — curious what's in your set.”

For founders and devs using Claude Code for more than just coding, this repo is a practical template for building your own library of reusable agent instructions. Fork it, adapt the prompts to your workflows, and treat them like you would any other project artifact.
