A Claude Code repo just crossed 181,000 stars. Almost 28,000 forks. All of this in less than ten months.

Inside: 28 agents, 119 skills, and a 354-line guide on using Claude Code like a pro.

Most people who star it never go back. The README is a wall.

I read all of it for you. Inside the mass I picked the agents, skills, and tips most useful to a startup founder. Below a playbook on how to use each one, when it pays off, and the copy-paste prompt to actually run it.

Here’s the cut.

The 5 skills:

  • market-research: Source-cited research on competitors, markets, and investors.

  • investor-materials: Pitch decks, one-pagers, memos, and financial models in VC-ready formats.

  • investor-outreach: Personalized cold emails to investors plus the follow-up cadence.

  • article-writing: Long-form writing in your voice, without the typical AI tone.

  • content-engine: One asset into native posts across LinkedIn, X, and beyond.

The 5 agents:

  • chief-of-staff: Communication triage and ready-to-send drafts.

  • planner: Turns a vague idea into operative steps with dependencies.

  • docs-lookup: Answers questions buried inside external documentation.

  • code-reviewer: Reviews what AI wrote before you ship it.

  • security-reviewer: Catches vulnerabilities before they hit production.

The 5 tips:

  • Memory persistence → Three hooks that make Claude remember between sessions.

  • Continuous learning → Claude writes skills from its own mistakes.

  • Model routing → Haiku for cheap work, Sonnet by default, Opus only when needed.

  • Turn off the MCPs you don’t really need →They eat tokens for nothing.

  • The /llms.txt trick → LLM-ready versions of any documentation in one click.

Inside you will find:

  1. The 5 business skills built explicitly for founders

  2. The 5 pre-built Claude agents that replace categories of busy-work

  3. The 5 tips to use Claude like a pro
