reprompt-cli 2.2.1

Discover, analyze, and optimize your prompts from AI coding sessions

re:prompt

Score, rewrite, and optimize your AI prompts -- the only CLI that improves your prompts automatically. No LLM needed.

See it in action

$ pip install reprompt-cli

# Rewrite a weak prompt into a better one (no LLM, rule-based)
$ reprompt rewrite "I was wondering if you could maybe help me fix the auth bug"
  34 → 52 (+18)

  ╭─ Rewritten ────────────────────────────────────────────────╮
  │ Help me fix the auth bug.                                  │
  ╰────────────────────────────────────────────────────────────╯

  Changes
  ✓ Removed filler (24% shorter)
  ✓ Removed hedging language

  You should also
  → Add actual code snippets or error messages for context
  → Reference specific files or functions by name
  → Add constraints (e.g., "Do not modify existing tests")

# Score any prompt instantly (research-backed, 30+ features)
$ reprompt score "Fix the auth bug in src/login.ts where JWT expires"
  Score: 40/100  (Fair)
  Tip: Include the error message -- debug prompts with errors are 3.7x more effective

# Compress prompts to save tokens
$ 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."
  Before: 28 tokens → After: 14 tokens (50% saved)

reprompt projects	Per-project quality breakdown -- sessions, scores, frustration signals

Optimize

Command	Description
reprompt build "task"	Build prompts from components -- task, context, files, errors, constraints. Model-aware (Claude/GPT/Gemini)
reprompt rewrite "prompt"	Rewrite prompts to score higher -- filler removal, restructuring, hedging cleanup
reprompt compress "prompt"	4-layer prompt compression (40-60% token savings typical)
reprompt distill	Extract important turns from conversations with 6-signal scoring

reprompt lint	Configurable prompt quality linter with CI/GitHub Action support
reprompt init	Generate .reprompt.toml config for your project

Manage

Command	Description
reprompt privacy	See what data you sent where -- file paths, errors, PII exposure
reprompt privacy --deep	Scan for sensitive content: API keys, tokens, passwords, PII
reprompt report	Full analytics: hot phrases, clusters, patterns (--html for dashboard)
reprompt digest	Weekly summary comparing current vs previous period
reprompt wrapped	Prompt DNA report -- persona, scores, shareable card
reprompt template save|list|use	Save and reuse your best prompts

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. Live score badge shows prompt quality as you type.

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.
