Composio HQ Composio
Choose a surface from the capabilities available in the current task, then keep the workflow on that surface unless the task itself requires the other one.
Choose the surface
- In a terminal or Codex environment, prefer the local Composio CLI for Composio work. If
composiois missing, explain how to install and sign in before choosing it; do not install software without user approval. Read references/cli.md before using that surface. - In ChatGPT web/app or another environment without a usable terminal, use callable, authorized hosted Composio app tools. Read references/mcp.md before using that surface.
- If both surfaces are available in a terminal or Codex environment, use the CLI unless the user explicitly requests the hosted surface or the required capability exists only there.
- If neither surface is available, explain both setup paths: authorize or enable the hosted app for ChatGPT work, or install and sign in to the CLI for terminal automation.
Do not tell a user in ChatGPT web/app or another hosted-only environment to install the CLI before using callable hosted app tools.
Execute safely
- For a read, use the narrowest suitable tool and summarize only the requested data.
- For an unknown capability, discover the tool first, inspect its schema, and then execute it.
- For a missing connection, complete authorization on the selected surface and resume the original operation there.
- Before a write, resolve ambiguous recipients, targets, scope, and payload. Once the write is confirmed, execute it exactly once.
- After a timeout or unclear write result, verify the target state or execution status before doing anything else. Never automatically retry an uncertain write through the other surface.
- Reject unbounded destructive work until the user narrows the scope and confirms the affected resources.
- Never expose credentials, tokens, connection secrets, or raw authentication material.
