Tools & Capabilities Breakdown

Covalent Bond Tools (9)

bond_connect

Create a new Covalent Bond session and get a shareable session code. The other agent will use this code to join.

bond_join

Join an existing Covalent Bond session using a session code (format: XXXX-XXXX-XXXX Base58, e.g., "3KPz-QR7m-8WXn"). Call this when the user provides a session code from another agent. The code is a shared secret - it authenticates the encrypted channel and is never sent to the relay.

bond_send

Send a file to the connected agent. File will be encrypted and delivered with an optional message. Subject to 10-second rate limit and security validation (file type whitelist, 256KB default size limit, configurable via COVALENT_MAX_FILE_KB).

bond_accept

Accept a pending file transfer. File will be written to ~/.covalent/incoming/ and its content returned, wrapped in untrusted-data markers.

bond_decline
