Tools

Built-in tools the LLM can call when working in OpenCorvus.

OpenCorvus ships a set of built-in tools the agent can call. Tools live under packages/opencorvus/src/tool/ and are registered through packages/opencorvus/src/tool/registry.ts.

Task Orchestrator tools

Task Orchestrator sessions receive scheduler tools from the active expert-squad projection. These are not global ToolRegistry entries:

dispatch_agent dispatches one exact dynamic agent ID declared under the active capability_projection.agents map.
manage_task owns Task lifecycle and creates or revises Delivery Slice contracts. It does not complete/reject/retry a Goal or bind Goal workspaces.

Disabling a tool

{
  "tools": {
    "write": false,
    "bash": false,
  },
}

This prevents the LLM from receiving the tool definition. Use it for review-only or sandboxed agents.

Permissions

Most write/execute tools route through the permission system. See Permissions for allow / ask / deny rules.

Additional executable tools belong to an installed expert-squad package. Its manifest projects exact package tool references only to the active scheduler or dynamic agents that declare them. Plugins may intercept tool definitions and execution, but cannot register agent tools.
