@echo-agent/coding

Echo's coding agent: file, search, shell and web tools mounted on top of echo-agent. Installs the echo-coding command.

Requires Bun. The executable is TypeScript with a #!/usr/bin/env bun shebang, and the package entry point is TypeScript source. Node is not supported for this package.

Status: pre-release. Nothing is published to npm yet and the public surface may change before the first 0.x release. Install from source for now.

Run it

git clone https://github.com/echo-yiyi/echo-agent.git
cd echo-agent
bun install
MOONSHOT_API_KEY=sk-... bun packages/coding/bin/echo-coding.ts

The command name stays echo-coding even though the package is scoped — the unscoped name was already taken on npm by an unrelated project.

echo-coding accepts the same options as echo-agent (--help). It runs every tool without asking, in the interactive UI and through a pipe alike — treat it as a script that may change files in the current directory.

Sessions belong to a directory and a command, so echo-agent and echo-coding never share a conversation even in the same directory.

What this package is

A product, not a framework layer. It owns its system prompt, its permission policy and the echo:workspace, echo:shell, echo:worktree and echo:web extensions, then hands that preset to echo-agent's startup logic. It does not change a line of echo-agent — which is exactly the path a third-party product would take on this runtime.

Full documentation is in the repository README.
