Coder's plugins

Coder's abilities come as plugins you can turn on and off. Type /plugins, or press Ctrl+P (Cmd+P on macOS) or F2.

Key	Does
Up, Down	Choose a plugin.
Space	Turn it on or off.
Enter	Open its settings.
Tab	Move between fields and buttons in settings.
Esc	Go back.

Your choices are saved and kept when you quit.

The built-in plugins

Plugin	Starts	What it does
Claude Code	On	Runs chats on Claude Code with this computer's Claude sign-in: everything Claude Code can do, with your own settings and skills, plus Coder's handoffs to other agents. While it's on and signed in, new chats can run on it.
Codex	On	Runs chats on Codex with this computer's ChatGPT sign-in, with its own models. Auto can pick it, or you can choose it with `Shift+Tab`.
OpenCode	On	Runs chats on OpenCode, with its free model or the models you set up in it; Coder checks each step before it runs. Listed only when OpenCode is installed.
Coder loop	On	Coder's own coding loop, on OpenAgents models with your sign-in or on your OpenRouter key.
ACP Subagents	On	Hands tasks to other coding agents installed here, such as Devin CLI, Cursor, Grok Build, Goose, Amp, or Kimi Code.
Solver	On	Takes a GitHub issue to a pull request. See Solve an issue.
Solver swarm	On	Hands several issues to several Solvers at once.
Agent channel	On	Lets the agents a chat hands work to tell each other what they're changing, and warns them about overlaps.
Token savers	On	Cuts what the agent reads and pays for: long build and test output is trimmed to its errors, with the full output saved to a file.
OpenAgents CLI	On	Lets Coder run the `openagents` command in this folder, for example to read and comment on GitHub issues.
Jev	On	Quick judgment calls while Coder works, like whether a step is done, from Jev, TypeSafe's small decision model. Uses your TypeSafe key or a compatible service.
OpenRouter BYOK	Off	Use OpenRouter models with your own OpenRouter key.
Brainstorm	Off	Looks up public profiles and how much influence they have, when you ask with `/brainstorm`.
Boat Cloud, GCE Cloud	Off	Run handed-off work on cloud machines you already have access to.

Turning a plugin off keeps its settings and keys, so turning it back on needs no setup.

OpenRouter BYOK

Use any OpenRouter model on your own key (get one at openrouter.ai).

In /plugins, choose OpenRouter BYOK and press Enter.
Paste your key in OpenRouter API key. Press Tab to reach Save, then Enter. Coder checks the key and shows Verified.
Back in the list, make sure the plugin is on (Space).
Type /models and pick a model. openrouter/free is OpenRouter's free router; fixed models also ask for a reasoning level and an output limit.

Or start Coder with the key in your environment, and Coder picks it up:

export OPENROUTER_API_KEY=sk-or-...
coder

Coder also reads OPENROUTER_API_KEY from a .env file in the folder you open. Keys are never shown on screen; to remove one, clear the field and save.

Jev

Jev answers small typed questions (yes or no, pick one, a score) with probabilities, which Coder and its own loop use for quick decisions.

Get a key at typesafe.ai.
In /plugins, choose Jev and press Enter.
Pick the connection (TypeSafe, or Vercel AI Gateway), paste the key, then press Tab to reach Save and Enter.

Or set TYPESAFE_API_KEY in your environment or .env before you run coder.

ACP Subagents

Open ACP Subagents in /plugins to see the coding agents Coder found on this computer, each with a checkbox. New ones start on.

Space or Enter turns the chosen agent on or off.
R looks for installed agents again.

Each agent uses its own sign-in. Install and sign in with its own program first: for Cursor, cursor-agent with its login or CURSOR_API_KEY. Devin CLI bills its own paid service for each run; turn it off here if you don't want Coder to use it.

Token savers

When it's on, long build, test, and lint output (from cargo test, npm test, pytest, go test, make, and the like) reaches the agent trimmed to the lines that matter, with the whole output saved to a file it can open when it needs more. This works on Claude Code and on Coder's own loop, and Codex is asked to run such commands the same way. Turn it off to send all output through unchanged.

Plugins you install

On macOS and Linux, plugins you install with openagents plugin install also appear in the list. Enter shows one's details and the commands to turn it on or off. See Plugins for writing and sharing your own.

From the command line

openagents coder plugins list
openagents coder plugins disable token-savers
openagents coder plugins enable openrouter-byok
printf '%s' '{"api_key":"sk-or-..."}' | openagents coder plugins configure openrouter-byok --stdin
openagents coder plugins check openrouter-byok

The plugin IDs are claude-code, codex, opencode, microcoder (Coder loop), acp-subagents, solver, solver-swarm, comms (Agent channel), token-savers, openagents-cli, jev, openrouter-byok, brainstorm, boat-cloud, and gce-cloud.
