Analyze what you type into AI tools -- prompt scoring, agent error loops, leaked credential detection, conversation distillation.

$ reprompt score "Fix the auth bug in src/login.ts where JWT expires"
  Score: 40/100  (Fair)
  Structure: 0/25 | Context: 8/25 | Position: 20/20 | Repetition: 0/15 | Clarity: 12/15
  Tip: Include the error message -- debug prompts with errors are 3.7x more effective

$ reprompt distill --last 3 --summary
  Session: feature-dev (42 turns, 18 important)
  Key moments: initial spec → auth module → test failures → JWT fix → passing
  Context: "Building auth system with JWT refresh tokens for Express API"

$ reprompt compress "I was wondering if you could please help me refactor this code. Basically what I need is to split this function into smaller helpers and add error handling."
  Before: 28 tokens → After: 14 tokens (50% saved)

Prompt Science

Scoring is calibrated against 4 research papers covering 30+ features across 5 dimensions:

All analysis runs locally in <1ms per prompt. No LLM calls, no network requests.

Conversation Distillation

reprompt distill scores every turn in a conversation using 6 signals:

• Position -- first/last turns carry framing and conclusions
• Length -- substantial turns contain more information
• Tool trigger -- turns that cause tool calls are action-driving
• Error recovery -- turns that follow errors show problem-solving
• Semantic shift -- topic changes mark conversation boundaries
• Uniqueness -- novel phrasing vs repetitive follow-ups

Session type (debugging, feature-dev, exploration, refactoring) is auto-detected and signal weights adapt accordingly.

Supported AI tools

Installation

pip install reprompt-cli            # core (all features, zero config)
pip install reprompt-cli[chinese]   # + Chinese prompt analysis (jieba)
pip install reprompt-cli[mcp]       # + MCP server for Claude Code / Continue.dev / Zed

Quick start

reprompt scan                       # discover prompts from installed AI tools
reprompt                            # see your dashboard
reprompt score "your prompt here"   # score any prompt instantly
reprompt distill --last 1           # distill your most recent conversation

Auto-scan after every session

reprompt install-hook               # adds post-session hook to Claude Code

Browser extension

Capture prompts from ChatGPT, Claude.ai, and Gemini directly in your browser:

1. Install the extension from Chrome Web Store or Firefox Add-ons
2. Connect to the CLI: reprompt install-extension
3. Verify: reprompt extension-status

Captured prompts sync locally via Native Messaging -- nothing leaves your machine.

Privacy

• All analysis runs locally. No prompts leave your machine.
• reprompt privacy shows exactly what you've sent to which AI tool.
• Optional telemetry sends only anonymous 26-dimension feature vectors -- never prompt text.
• Open source: audit exactly what's collected.
