What Claude Code Mode does

Code mode for Claude Code: a bridge to Pi's codemode. The model writes one script that calls the session's tools; only the output returns.

README

codemode for Claude Code: a bridge to Pi's code mode

**Code mode for Claude Code:** one tool that lets the model write a JavaScript script that calls the session's own tools (`Read`, `Bash`, `Write`, `Edit`, the MCP resource tools, and the session's MCP tools), and returns only the script's output. Many tool calls become one, and large intermediate results stay out of the context window.

**Inspired by [Pi's codemode](https://github.com/earendil-works/pi/blob/main/packages/coding-agent/docs/codemode.md)**, by Earendil. Earendil's post [**"You Said No MCP!"**](https://earendil.com/posts/you-said-no-mcp/) explains the idea and why it works, and Armin Ronacher's [**"What is Codemode"**](https://lucumr.pocoo.org/2026/10/6/codemode/) describes it from the harness side. This project does not reimplement it. **It is a bridge:** it runs Pi's own script runtime, [`@earendil-works/pi-codemode`](https://github.com/earendil-works/pi/tree/main/packages/codemode) (QuickJS in WebAssembly), and connects each `tools.*` call the script makes to Claude Code's own tool call. Your permission rules, prompts and hooks still apply to every one of them, and a script written for Pi's codemode reads the same here.

**Status: pilot (v0.7.3).** It exposes `Read`, `Bash`, `Write`, `Edit`, the three MCP resource tools, and every MCP tool connected in the session. The design is in [ADR 0001](docs/adr/0001-a-claude-code-mod-hosts-the-pi-codemode-runtime-in-a-node-child-process-and-routes-every-nested-call-through-the-session-s-tool-call.md), which is still *Proposed*. The bridge overhead and the task-level savings are measured — see [Benchmarks](#benchmarks) and [issue 0005](docs/issues/0005-benchmarks-show-the-bridge-overhead-and-the-token-turn-and-time-savings-of-codemode-per-task.md).

![Claude Code picks the codemode tool on its own: one script lists the TypeScript files with git, reads all five in parallel, filters the TODO lines, and only the filtered output returns](docs/media/codemode-
