Hazzel

Hazzel lives in your terminal. It reads code, edits files, runs commands, and works with git — always with your approval first.

Most coding agents keep getting bigger. Hazzel stays small on purpose.

The model suggests what to do. Hazzel decides whether and how to do it. Every mutation goes through you: file changes show a diff before they apply, shell commands ask first, and destructive git stays blocked.

If you want the most feature-heavy agent, there are better options. If you want a terminal agent you can see through, that's Hazzel.

Read, search, and list your codebase. Tag files with @path to put them in context.

Create and edit files with diff preview and approval. Undo with /undo .

Run shell commands with approval and timeout, sandboxed to your project root.

Plan mode ( /plan on ): read-only exploration. Hazzel proposes a numbered plan, changes nothing until you run /plan off .

Prove mode ( /prove on ): smoke-checks Python edits in /tmp before you trust them.

Git-native: /status , /diff with file browser, /commit with suggested message, /branch , /log , /push , /pull , /sync . No --force , no reset --hard via shell.

No web browsing, no pull requests, no deploys, no background agents, no session persistence across restarts. It doesn't replace your editor — it stays in the terminal next to it.
