Excerpt

Editing Cordis compositions

Every capability in this harness is a plugin row in a cordis.yml. There is no separate configuration language: changing what an agent can do means changing which rows are composed for it.

Off-limits

Never edit, delete, or overwrite a preset that ships with the deployment — the agent-presets directory beside the deployment's own config, which supplies standard, code, minimal, and cordis. Never escalate the sandbox to reach it, even when a change there looks quicker. An upgrade overwrites that install, and corrupting cordis disables preset authoring itself. Reading a shipped composition is the intended way to start; writing to one is not, and neither is editing the host composition to work around a preset limitation.

This is the opening of the README. Read the full README on GitHub.
