You let the AI cook. Now find out what it actually did.

whatdiditdo.doruk.ch · npm

One command to see everything your AI coding agent changed. Works after any AI coding session — Cursor, Copilot, Aider, Windsurf, and more.

Quick Start

Run in any git repo after an AI session:

npx whatdiditdo

That's it. No install needed.

Development

npx whatdiditdo

That's it. Run it in any git repo after an AI session.

What you get

• Files changed — added, modified, deleted with line counts
• Stats — total lines added/removed, new dependencies
• AI summary — plain-english explanation of what happened (AI-powered)
• Security flags — catches hardcoded API keys, modified .env files, committed secrets
• Quick share — copy-paste one-liner for Slack/Discord
• Emoji summary — compact one-line recap printed after every run

Auto-generate PR descriptions

The killer feature. After an AI session:

npx whatdiditdo --pr

Generates a ready-to-paste PR title and body with:

• Summary of changes
• File change table
• New dependencies listed
• Security warnings
• Test plan checklist

Pipe it: npx whatdiditdo --pr --no-ai | pbcopy

Quick share

Every run prints a one-line emoji summary you can paste into Slack or Discord:

📊 4 files · +120 -30 · 2 new deps

Security scanning

Automatically flags:

• Hardcoded API keys and tokens
• Modified .env files
• Private keys (RSA, etc.)
• Credentials in URLs

Auto-run after every commit

Install a git hook so whatdiditdo runs automatically after every commit:

npx whatdiditdo --hook

To remove it:

npx whatdiditdo --unhook

Undo AI changes

Review what changed and selectively revert:

npx whatdiditdo --undo

Lists all changed files with a preview, then lets you revert individual files or the entire last commit.

HTML report

Open a styled HTML report in your browser:

npx whatdiditdo --web

Includes diffs, file lists, security flags, and AI summary in a dark-themed dashboard.

Blame agent

Detect which AI tool made the changes:

npx whatdiditdo --blame-agent

Checks commit messages, tool-specific config files, and git settings to identify the agent (Cursor, Copilot, Aider, Windsurf, etc.).

Webhook notifications

Send results to Slack, Discord, or any webhook:

npx whatdiditdo --notify https://hooks.slack.com/services/...
npx whatdiditdo --notify https://discord.com/api/webhooks/...

Auto-detects the platform and formats the payload accordingly. For unknown URLs, sends a plain JSON summary.

Requirements

• Node.js 18+
• Git
• AI CLI — optional, only needed for AI summary

Development

git clone https://github.com/peaktwilight/whatdiditdo
cd whatdiditdo
npm install
npm run build

Full disclosure

This tool was vibe-coded by an AI agent. We used whatdiditdo to audit its own creation. It's turtles all the way down.
