Kimi Agent (Rust)

Rust implementation of Kimi Code CLI. Wire-only JSON-RPC agent server over stdio.

Build & Run

cargo build -p kimi_agent
./target/debug/kimi_agent

Install

Build and install the binary to $PATH_ROOT/bin/:

# Dev build
PATH_ROOT=~/.local make install

# Release build (optimized)
PATH_ROOT=~/.local make install-release

Available make targets:

• make build — build dev binary
• make build-release — build optimized release binary
• make install — build dev + install to $PATH_ROOT/bin
• make install-release — build release + install to $PATH_ROOT/bin
• make clean — remove build artifacts
• make help — show all targets

Note: make install* requires PATH_ROOT environment variable to be set.

Test

cargo test                  # all
cargo test -p kimi_agent    # agent
cargo test -p kosong        # LLM abstraction
cargo test -p kaos          # OS abstraction

Workspace

Crate	Purpose
kimi_agent	Main binary — wire server, tools, agent loop, MCP
kosong	LLM abstraction — messages, tool schemas, providers
kaos	OS abstraction — LocalKaos, path semantics

Relationship to Python

This repo is a Rust rewrite of the Python kimi-cli runtime. The two must stay compatible on wire protocol, message formats, ~/.kimi data layout, tool schemas, and all other externally observable behavior. Python is the source of truth.

The Python repo is pinned as a git submodule at kimi-cli/:

git submodule update --init

Version numbers must always match kimi-cli exactly.
