│ Prompts: 1,063 (295 unique) Sessions: 890 │

$ 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)
"Help me refactor this code. Split this function into smaller helpers and add error handling."

Prompt Science
Scoring is calibrated against 4 research papers covering 30+ features across 5 dimensions:
| Dimension | What it measures | Paper |
|---|---|---|
| Structure | Markdown, code blocks, explicit constraints | Prompt Report 2406.06608 |
| Context | File paths, error messages, technical specificity | Google 2512.14982 |
| Position | Instruction placement relative to context | Stanford 2307.03172 |
| Repetition | Redundancy that degrades model attention | Google 2512.14982 |
| Clarity | Readability, sentence length, ambiguity | SPELL (EMNLP 2023) |
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.

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:
- Install the extension from Chrome Web Store
- Connect to the CLI:
reprompt install-extension - Verify:
reprompt extension-status
Captured prompts sync locally via Native Messaging -- nothing leaves your machine.
CI integration
GitHub Action
# .github/workflows/prompt-lint.yml
- uses: reprompt-dev/reprompt@main
with:
score-threshold: 50 # fail if avg prompt score < 50
strict: true # fail on warnings too
pre-commit
# .pre-commit-config.yaml
repos:
- repo: https://github.com/reprompt-dev/reprompt
rev: v1.6.1
hooks:
- id: reprompt-lint
Direct CLI
reprompt lint --score-threshold 50 # exit 1 if avg score < 50
reprompt lint --strict # exit 1 on warnings
reprompt lint --json # machine-readable output
Privacy
- All analysis runs locally. No prompts leave your machine.
reprompt privacyshows 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.
