Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| instancesA | List all connected opencode instances with their current status (busy/idle). Call this to see what machines are available. |
| sendB | Send a message to the most recent opencode session on an instance. Streams the response back in real-time. Set abort=true to stop a running task instead of sending a message. |
| readA | Read the last few messages from the most recent opencode session on an instance. Use this to see what has been happening without sending a new message. |

Scored across 3 tools
Each tool has a clearly distinct purpose: listing instances, reading session history, and sending messages. No overlap or ambiguity.
All tool names are lowercase and concise, but 'instances' is a noun while 'read' and 'send' are verbs, creating a slight pattern inconsistency.
Three tools cover the essential operations for interacting with opencode instances (list, read, send) without unnecessary bloat.
Core workflows are covered, but there is no tool to select a specific instance or start a new session, which are minor gaps.
