ACP
What it does
Delegates a coding task to an external agent over the Agent Client Protocol. The agent runs as a subprocess and streams results back into the conversation.
Setup
You install the adapter binary (for example a Codex ACP adapter) if it is not already on PATH. Cadence can install the allowlisted adapter package once in a sandbox. Custom agent commands are never auto-installed. You bring that agent's own credentials. Cadence is not an Anthropic or OpenAI cloud product; ACP is a pipe to software you chose.
Permissions
- The spawned agent runs in the working directory you name.
- Do not bounce the assistant (
cadence sleep/wake) to start ACP. That kills the conversation.
Common prompts
| You say | What happens |
|---|---|
| “Have Codex implement the failing test in this folder” | ACP spawn in that directory |
| “Set up the coding agent adapter” | Installs the allowlisted adapter if missing |
