Customization Agents

Custom agents

Custom agents are local agent installs that build into local Docker images. They live under ~/.aicage-custom/agents/ and behave like locally built built-in agents.

If a custom agent name matches a built-in agent name, the custom agent overrides it.

Directory layout

~/.aicage-custom/agents/<AGENT>/
├─ agent.yaml (or agent.yml)
├─ install.sh
└─ version.sh

The directory name is the agent id used on the CLI, for example: aicage <AGENT>.

agent.yaml

Required keys:

agent_path:
  - ~/.forge
agent_full_name: Forge Code
agent_homepage: https://forgecode.dev/

Optional keys:

  - debian

install.sh

Runs during the Docker build of the local image. Keep it deterministic and non-interactive.
