Autonomous MVP development for Claude Code.
Plan → scaffold → build → verify → deliver. No HITL. Just ship MVPs.
You have an idea. FrinkLoop ships it.
A 4-question intake conversation becomes a deploy-ready MVP — code, README, landing page, screenshots, and a Phase-2 plan — fully autonomously, surviving Claude Code's 5-hour usage windows. No human in the loop after intake. Just plan, scaffold, build, iterate.
Per-project state lives inside each project's own .frinkloop/ directory. The plugin itself stays at ~/.claude/plugins/frinkloop/. Local-first. No SaaS in the middle.
In Claude Code, run two commands:
/plugin marketplace add fernandoleyra/FrinkLoop
/plugin install frinkloop
That's it. Type /plugin list to confirm.
/frinkloop new
| Command | Purpose |
|---|---|
/frinkloop |
Router / help |
/frinkloop new |
Start intake chat → scaffold → build |
/frinkloop resume <project> |
Resume a paused or quota-stopped loop |
/frinkloop status [<project>] |
Snapshot of loop state |
/frinkloop pause <project> |
Flush state, write handoff, exit cleanly |
/frinkloop ds |
Design system manager (list / new / clone / push) |
/frinkloop deliver <project> |
Run the deliverable packaging step |
- Intake chat — 4 short questions capture what you're building, who it's for, the stack, and the design system.
- Scaffolder — picks a starter template from a curated registry (Next.js, Vite + shadcn, Astroship, Hono, FastAPI, Citty, uvinit, Expo, WXT, Discord/Slack bots) and applies recipes.
- Build loop — Stop-hook spine that plans → builds → verifies → iterates against a target spec, with parallel subagent fan-out and worktree isolation for safe concurrency.
- Design system store — built-in
claude-defaultpreset, plus tokens-awarenew/clone/pushfor cross-project reuse. - Local learning — events log + rolled-up profile that pre-fills intake defaults from your past projects.
- Quota-aware resume — launchd/cron-scheduled wake-up after the 5-hour Claude Code window resets, so long builds finish on their own.
- Deliverable packaging — README rewrite, landing page, screenshot pipeline (Playwright), deploy step (Vercel/Netlify/Cloudflare via recipes), Phase-2 plan.
- Autonomy is efficiency. Once intake is done, FrinkLoop runs without you. Sit down to a built MVP.
- Local-first. All state under
~/.claude/plugins/frinkloop/and<project>/.frinkloop/is local. No telemetry. No analytics. No backend. - Token-friendly. Caveman-style compression on the loop spine; recipes are deterministic and idempotent so iteration costs stay low.
- Honest about scope. Phase-2 work (Stripe wiring, real auth, monitoring) is enumerated as a delivered artifact — not silently skipped.
This repo is the source of the FrinkLoop Claude Code plugin:
| Path | Purpose |
|---|---|
plugin/ |
The plugin payload — skills, commands, hooks, lib, templates, recipes. Installed at ~/.claude/plugins/frinkloop/. |
tests/ |
bats tests organized by plan number (tests/plan-N/). |
docs/superpowers/specs/ |
Design specs. |
docs/superpowers/plans/ |
Per-plan implementation plans + roadmap. |
.worktrees/ |
Local git worktrees for parallel plan branches (gitignored). |
Per-user, per-project state goes inside the project itself in .frinkloop/ — this repo never holds user projects.
npm install # bats + ajv-cli
npm test # runs bats -r tests/If FrinkLoop helps you ship something, please star the repo. Stars are the single biggest signal that keeps this project alive and free for everyone.
FrinkLoop stands on the shoulders of:
- Ralph Loop by Geoffrey Huntley — the disk-state Stop-hook loop primitive.
- caveman by Julius Brussee — token compression.
- obra/superpowers — TDD, verification, brainstorming, subagent patterns.
- Anthropic Claude Code — the platform that made plugins like this possible.
- Y Combinator — pitch frameworks for intake structure and communication.
If you build something on top of FrinkLoop, ping me — I'd love to see it.
