An open-source experiment for AI developers

Make your coding agent work smarter.

Turn vague requests into sharper prompts. Turn agent logs into practical lessons. A lightweight coach for the way you already build software.

YOUR ORIGINAL PROMPT

Fix the bug in the checkout flow.

↓ context added

A MORE USEFUL PROMPT

Goal
Find and fix the checkout bug without changing unrelated behavior.

Constraints
Trace the failing path first. Keep the patch minimal.

Acceptance criteria
Explain the root cause and add a regression test.

✳Prompt qualityMore context, less guesswork

⌁Session insightsSpot repeated errors & tool loops

BUILT FOR THE REALITY OF AI-ASSISTED SOFTWARE WORK

ONE SMALL WORKSPACE

Better inputs. Better feedback loops.

Start with two workflows that help you learn from your own coding-agent usage.

✳

01 / PROMPT COACH

Say what you mean, clearly.

Reshape a rough task into a structured brief with context, constraints, steps, and acceptance criteria. Edit the result before you copy it into your coding agent.

02 / SESSION ANALYZER

Learn from the work.

Inspect a pasted log or JSONL file for tool activity, errors, repeated failure signals, and approximate text size. Use the findings to improve the next run.

PRIVATE BY DEFAULT

Your code context belongs to you.

The prototype uses browser-side heuristics. It doesn't send prompts or logs to a server, and it doesn't require an API key. Don't paste secrets into any tool unless you have reviewed how it handles data.
