Find Callees
find-callees · Query · CorePlugin · Code discovery and navigation
Finds distinct method and constructor targets invoked by a source executable symbol or selected executable region. Use this for outgoing calls; use find-callers for incoming call sites. Reads the loaded workspace without executing code. Direct calls are the default; includeIndirect traverses reachable source bodies up to maxDepth (default 3, direct calls at depth 1). Nested lambda and local-function bodies are skipped during each body scan. Returns source and a bounded callees collection, not call sites or runtime dispatch targets. calleesLimit defaults to 100; check callees.hasMore for result truncation within the requested depth.
Availability: Built in and published in every operational mode.

Request
| Property | Type | Required | Description |
|---|---|---|---|
symbol |
object |
No | Symbol whose callees should be found. |
location |
object |
No | Source location or executable region whose contained callees should be found. |
includeIndirect |
boolean |
No | Whether reachable source callees should be traversed transitively. |
maxDepth |

No | The maximum call depth to traverse when indirect callees are included. Direct callees are at depth one. |
calleesLimit |
integer | null |
No | Maximum number of results to return. |
expectedSnapshot |
object | null |
No | Echo the snapshot returned with the data or transaction state used to construct this request. |
workspace |
object | null |
No | Provide workspaceId, alias, path, or any combination. |
Response
Success response
| Property | Type | Required | Description |
|---|---|---|---|
ok |
boolean constant (true) |
Yes | Whether the tool invocation succeeded. |
data |
object | null |
Yes | Tool-specific result payload. |
snapshot |
object |
Yes | Exact immutable workspace snapshot associated with the result, when available. |
warnings |

Yes | Structured error details when the invocation failed. |
continuation |
oneOf |
No | Action the agent should take before retrying or continuing. |
diagnostics |
array |
No | Diagnostics that explain the failed invocation. |
warnings |
array |
No | Non-fatal warnings the agent should consider. |

Bounded collections and continuation
These response locations publish returned items with explicit bounds and continuation state:

Continuations and required actions
A response may include a structured continuation at the following schema location. Follow its tool call or user-action instruction instead of guessing how to continue:
