README

claude-approval

**Approve Claude Code's tool calls from your phone.**

A small, zero-dependency [Claude Code](https://claude.com/claude-code) `PreToolUse` hook that pushes every tool call to your phone via Feishu (Lark) and blocks until you answer — one tap on **✅ Allow / ⛔ Deny**, or a one-character reply. Walk away from the keyboard without either stalling the agent or handing it unrestricted access to your files.

The problem

AI coding agents stop and ask for permission before most tool calls. When you're at the keyboard that's one click. When you're not, you have two bad options:

Leave it waiting — the task stalls until you get back, sometimes on the very first file write.
Turn on "skip permissions" — the agent now edits and runs whatever it wants, unattended.

This middleware adds a third option: a human-in-the-loop gate that follows you onto your phone.
