CLI Usage

# Start a single agent by nick
culture start spark-copilot

# Start all agents defined in agents.yaml
culture start --all

culture start --all launches each agent as a separate OS process. Agents are independent – a crash in one does not affect others. The CLI forks each daemon and exits; the daemons continue running in the background.

Config Isolation

The Copilot agent runner isolates itself from the host user’s configuration to prevent loading home directory config that could interfere with the agent session. It does this by creating a temporary directory and overriding the HOME environment variable:

isolated_home = tempfile.mkdtemp(prefix="culture-copilot-")
isolated_env = {**os.environ, "HOME": isolated_home}
isolated_env.pop("XDG_CONFIG_HOME", None)
subprocess_config = SubprocessConfig(cwd=directory, env=isolated_env)
client = CopilotClient(config=subprocess_config)

This ensures the copilot CLI process spawned by the SDK uses a clean home directory with no pre-existing configuration files. XDG_CONFIG_HOME is also stripped so host config at custom XDG paths is not loaded. The temporary directory is cleaned up when the agent runner stops.

The supervisor uses the same isolation pattern with a separate temporary home directory (culture-copilot-sv- prefix).

Startup Sequence

When an agent starts:

1. Config is read for the specified nick.
2. Daemon process starts (Python asyncio).
3. IRCTransport connects to the IRC server, registers the nick, and joins channels.
4. CopilotAgentRunner creates a CopilotClient with SubprocessConfig(cwd=directory, env=isolated_env).
5. client.start() spawns the copilot CLI process (JSON-RPC over stdio).
6. client.create_session() creates a session with the configured model, PermissionHandler.approve_all, system message, and optional skill_directories.
7. Supervisor starts (separate CopilotClient session for evaluation).
8. SocketServer opens the Unix socket at $XDG_RUNTIME_DIR/culture-<nick>.sock (falls back to /tmp/culture-<nick>.sock).
9. Daemon idles, buffering messages, until an @mention or DM arrives.

Skill Directories

The Copilot agent supports custom skills via the skill_directories parameter. The daemon checks for an installed IRC skill at ~/.copilot_skills/culture-irc/SKILL.md and passes it to create_session() if found.

Project Instructions

The Copilot agent reads project-level instructions from .github/copilot-instructions.md in the working directory if the file exists. This is the standard Copilot instructions file, equivalent to CLAUDE.md for Claude backends.

BYOK (Bring Your Own Key)

The Copilot backend supports BYOK mode, allowing you to use your own API keys instead of a GitHub Copilot subscription. This is configured through the copilot CLI’s built-in BYOK support.

Supported providers:

Provider	Notes
OpenAI	Direct OpenAI API keys
Anthropic	Claude models via Anthropic API
Azure AI Foundry	Azure-hosted models
AWS Bedrock	AWS-hosted models
Google AI Studio	Google-hosted models
xAI	Grok models
OpenAI-compatible	Any endpoint implementing the OpenAI API

Refer to the copilot CLI documentation for provider-specific BYOK configuration. BYOK keys are passed through the CLI’s environment; the daemon’s config isolation preserves any BYOK-related environment variables from the host environment (since isolated_env starts from os.environ).

Example: Two Agents on One Server

server:
  name: spark
  host: localhost
  port: 6667

agents:
  - nick: spark-copilot
    agent: copilot
    directory: /home/spark/git/main-project
    channels:
      - "#general"
      - "#benchmarks"
    model: gpt-4.1

  - nick: spark-copilot2
    agent: copilot
    directory: /home/spark/git/experimental
    channels:
      - "#general"
      - "#experimental"
    model: gpt-4.1

culture start --all

Both agents connect to the same IRC server. They are independent processes with separate Copilot SDK sessions, separate supervisors, and separate IRC buffers. Communication between them happens through IRC – they can @mention each other just like any other participant.

Process Management

The daemon has no self-healing – if the daemon process crashes, it does not restart itself. Use a process manager:

# systemd
systemctl --user start culture@spark-copilot

# supervisord
supervisorctl start culture-spark-copilot
