Foundry Canvas does not open for existing-agent configuration or redeployment

[qinezh]

Description

Microsoft Foundry Canvas currently appears to open automatically only when the user asks to create, build, design, set up, or scaffold a new Foundry agent. It does not reliably open when the user wants to work on an existing agent.

Affected requests include:

• Connect an existing Foundry Toolbox to an existing agent
• Switch the model used by an existing agent
• Deploy or redeploy an existing agent

Expected behavior

Microsoft Foundry Canvas opens automatically for these existing-agent workflows so the user can select the workspace agent and use the Canvas controls for models, Toolboxes, and deployment.

Current behavior

The request continues through the normal chat workflow without opening the Canvas. Deployment-only requests are specifically excluded from Canvas routing.

Example prompts

• Add my existing Foundry Toolbox to the current agent
• Switch my existing Foundry agent to gpt-4.1
• Deploy this existing agent to Foundry again
