# Resolve Tools

`POST /tools/resolve`

Resolve an agent's tool references into model-ready specs.

Validates Composio connections up front and enriches each action from the
catalog, so a running agent (e.g. Pi) gets ``customTools`` whose ``execute``
routes back through ``POST /tools/call`` — provider keys stay server-side.

## Request body

- ToolResolveRequest
  - `tools` union[]
    - union
      - BuiltinToolConfig — Legacy entry, accepted so revisions written before the rework still parse. Built-in tools are always active and are no longer configured here; the resolver drops every entry with a warning. Keep this arm until the dual-read window closes.
