acp

Run the ACP (Agent Client Protocol) bridge that talks to a ThinkFleet Gateway.

This command speaks ACP over stdio for IDEs and forwards prompts to the Gateway over WebSocket. It keeps ACP sessions mapped to Gateway session keys.

Usage

thinkfleetbot acp

# Remote Gateway
thinkfleetbot acp --url wss://gateway-host:18789 --token <token>

# Attach to an existing session key
thinkfleetbot acp --session agent:main:main

# Attach by label (must already exist)
thinkfleetbot acp --session-label "support inbox"

# Reset the session key before the first prompt
thinkfleetbot acp --session agent:main:main --reset-session

ACP client (debug)

Use the built-in ACP client to sanity-check the bridge without an IDE. It spawns the ACP bridge and lets you type prompts interactively.

thinkfleetbot acp client

# Point the spawned bridge at a remote Gateway
thinkfleetbot acp client --server-args --url wss://gateway-host:18789 --token <token>

# Override the server command (default: thinkfleetbot)
thinkfleetbot acp client --server "node" --server-args thinkfleetbot.mjs acp --url ws://127.0.0.1:19001

How to use this

Use ACP when an IDE (or other client) speaks Agent Client Protocol and you want it to drive a ThinkFleet Gateway session.

1. Ensure the Gateway is running (local or remote).
2. Configure the Gateway target (config or flags).
3. Point your IDE to run thinkfleetbot acp over stdio.

Example config (persisted):

thinkfleetbot config set gateway.remote.url wss://gateway-host:18789
thinkfleetbot config set gateway.remote.token <token>

Example direct run (no config write):

thinkfleetbot acp --url wss://gateway-host:18789 --token <token>

Selecting agents

ACP does not pick agents directly. It routes by the Gateway session key.

Use agent-scoped session keys to target a specific agent:

thinkfleetbot acp --session agent:main:main
thinkfleetbot acp --session agent:design:main
thinkfleetbot acp --session agent:qa:bug-123

Each ACP session maps to a single Gateway session key. One agent can have many sessions; ACP defaults to an isolated acp:<uuid> session unless you override the key or label.

Zed editor setup

Add a custom ACP agent in ~/.config/zed/settings.json (or use Zed’s Settings UI):

{
  "agent_servers": {
    "ThinkFleetBot ACP": {
      "type": "custom",
      "command": "thinkfleetbot",
      "args": ["acp"],
      "env": {}
    }
  }
}

To target a specific Gateway or agent:

{
  "agent_servers": {
    "ThinkFleetBot ACP": {
      "type": "custom",
      "command": "thinkfleetbot",
      "args": [
        "acp",
        "--url", "wss://gateway-host:18789",
        "--token", "<token>",
        "--session", "agent:design:main"
      ],
      "env": {}
    }
  }
}

In Zed, open the Agent panel and select “ThinkFleet ACP” to start a thread.

Session mapping

By default, ACP sessions get an isolated Gateway session key with an acp: prefix. To reuse a known session, pass a session key or label:

• --session <key>: use a specific Gateway session key.
• --session-label <label>: resolve an existing session by label.
• --reset-session: mint a fresh session id for that key (same key, new transcript).

If your ACP client supports metadata, you can override per session:

{
  "_meta": {
    "sessionKey": "agent:main:main",
    "sessionLabel": "support inbox",
    "resetSession": true
  }
}
