Build your own AI Chief of Staff inside Claude Code. 22 commands, a growth diagnostic, and a harness to extend it to your workflow.
Free to install. No separate Foundation account or backend. Claude Code supplies the AI and has its own account and network requirements. Foundation keeps its durable outputs as local files in your project.
First, cd into your project directory. The commands install globally, but your CLAUDE.md brain file and the harness guide land wherever you run this:
curl -fsSL https://raw.githubusercontent.com/ronsleyvaz/Friday-Foundation/release/install.sh | bash
You need Claude Code installed first. Get it at https://docs.anthropic.com/claude-code
The installer drops the commands into ~/.claude/commands/, creates a CLAUDE.md in your current directory from the template (any existing one is left untouched), fetches the harness guide, and tells you what to do next.
Open Claude Code in your project directory. You have two good first moves.
Your fastest win, no setup required:
/amplify
Five minutes. It runs the growth diagnostic on your numbers and writes a 90-day plan to friday/growth.md.
Optional, but it sharpens every other command:
/voice-installer
It reads your writing samples, builds a voice profile, and writes it to friday/voice.md. Every command that runs after reads that profile and writes in your voice instead of a generic AI voice. Skipping it is safe: commands fall back to a neutral, direct style until you run it.
Want the full walkthrough first? The manual covers every command, the friday/ folder, and how to extend Foundation: docs/foundation-manual.md.

Workflow commands write to a friday/ folder in your project directory. That folder is your config, growing over time. /new-capability is the developer-tool exception: it scaffolds commands/<name>.md and may create docs/skill-writing-playbook.md on its first run.
/amplify is the flagship capability.
It walks you through eight business vital signs, detects your growth stage, maps to your priority quadrant (Revenue, Brand, Audience, or Operations), runs an ethics check on the recommendation, and writes a 90-day plan to friday/growth.md.
It takes about five minutes. It tells you where to push next and which AI tools to use first, matched to your experience level.
Based on the Amplify AI method. Full breakdown in the book: https://www.amazon.com/Amplify-Integrating-Intelligence-Humanity-Acceleration/dp/1998756831
curl -fsSL https://raw.githubusercontent.com/ronsleyvaz/Friday-Foundation/release/install.sh | bash -s -- amplify
Replace amplify with any command name to install just that one.
Run /new-capability <name> in Claude Code. It scaffolds a command file with the right frontmatter and step structure.

New here? The best place to start is a good first issue. Each one is a self-contained command to build, with the founder problem and the definition of done written out.
You can scaffold your first command in about ten minutes, and polish it into something you would ship in an hour or two. CONTRIBUTING.md has the step by step, the quality bar, and how to get credit for what you add.
If Foundation is useful to you, star the repo. It is the cheapest way to help more founders find it.
Twelve commands started as methodology from five open-source projects: gstack,
Matt Pocock's skills repo, and three founder-focused skill packs. Full list and
sources in CREDITS.md.
