Prompt Loop
Turn an idea into a coding prompt your AI agent can actually build — then review what it builds against the requirements, and loop until it passes.
Prompt Loop is an implementation supervisor for coding agents (Claude Code, Codex, Cursor, …). It doesn't write your app — it makes sure your agent builds the right thing: it turns your idea into concrete acceptance criteria, generates the exact build prompt, then reviews the real code your agent produced against those criteria and hands you a precise follow-up prompt for whatever's missing.
The loop
- Describe your idea — plain language, e.g. "a notes app where users register and only see their own notes."
- Review the requirements — Prompt Loop generates a checklist of acceptance criteria. Confirm or regenerate.
- Get the coding prompt — a detailed build prompt you paste into your agent.
- Build it — your agent writes the code.
- Review — Prompt Loop reads the actual code against each criterion and scores it (satisfied / partial / risky / missing).
- Loop — copy the generated follow-up prompt back into your agent, re-review, repeat until the gate passes.
Everything is guided from one panel: Prompt Loop: Start.
Getting started
- Sign up on the Prompt Loop website and verify your email.
- In VS Code, run Prompt Loop: Start (or Prompt Loop: Log In) from the Command Palette.
- Log in with your email — the first login on a machine claims 10 free credits.
- Describe your idea and follow the steps.
Your login is remembered securely (in the OS keychain), so you stay signed in across restarts.
Credits
Generation runs on Prompt Loop's servers and is metered by credits — 1 credit per model call (a review is 2). Your balance shows at the top of the wizard and ticks down as you go. When you run out, Prompt Loop tells you cleanly (more ways to top up are coming soon).

Purpose |
promptLoop.projectId |
The active project id reviewed against this workspace. |
promptLoop.baseCommit |

Reviews use git to track exactly what your agent changed. If the folder isn't a git repo yet, the wizard offers to set up a baseline for you.
