## Calls

- [Codeunit 4359 "Custom Agent Profile Mgt"](../codeunit/4359.md) (2 calls: `OnOpenPage → IsProfileEditable`, `OnOpenPage → IsWebClient`)
- [Codeunit 4321 "Agent"](../codeunit/4321.md) (1 call: `GetCustomAgentFields → GetModelName`)
- [Codeunit 4353 "Agent Designer Environment"](../codeunit/4353.md) (1 call: `OnOpenPage → VerifyCanRunOnCurrentEnvironment`)

## Called by

- [Page extension 3309 "PA Purchase Invoice List"](../pageextension/3309.md) (1 call: `ShowTaskPaneForLatestAgentTask → (object)`)

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "pageextension", object_name: "Agent Card")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
