Long executor names and error messages also broke UI layout. **Changes:** - Add ExecutorActionItemResource to match Python DevUI implementation - Track item IDs per executor using dictionary in AgentRunResponseUpdateExtensions - Reuse same item ID across invoked/completed/failed events for proper pairing - Add truncateText() utility to workflow-utils.ts - Truncate executor names to 35 chars in execution timeline - Truncate error messages to 150 chars in workflow graph nodes ** Details:** - ExecutorActionItemResource registered with JSON source generation context - Dictionary cleaned up after executor completion/failure to prevent memory leaks - Frontend item tracking by unique item.id supports multiple executor runs - All changes follow existing codebase patterns and conventions Tested with review-workflow showing correct executor highlighting and state transitions for sequential and concurrent executors. * format fixes, remove cors tests * remove unecessary attributes --------- Co-authored-by: Mark Wallace <127216156+markwallace-microsoft@users.noreply.github.com> Co-authored-by: Reuben Bond <reuben.bond@gmail.com> * DevUI: support having both an agent and a workflow with the same id in discovery (#2023) * Python: Fix Model ID attribute not showing up in `invoke_agent` span (#2061) * Best effort to surface the model id to invoke agent span * Fix tests * Fix tests * Version 1.0.0-preview.251107.2 (#2065) * Version 1.0.0-preview.251110.2 (#2067) * Update README.md to change Grafana links to Azure portal links for dashboard access (#1983) * .NET - Enable build & test on branch `feature-foundry-agents` (#2068) * Tests good, mkay * Update .github/workflows/dotnet-build-and-test.yml Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Enable feature build pipelines --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-authored-by: Roger Barreto <19890735+rogerbarreto@users.noreply.github.com> * Python: Add concrete AGUIChatClient (#2072) * Add concrete AGUIChatClient * Update logging docstrings and conventions * PR feedback * Updates to support client-side tool calls * .NET: Move catalog samples to the HostedAgents folder (#2090) * move catalog samples to the HostedAgents folder * move the catalog samples' projects to the HostedAgents folder * Bump OpenTelemetry.Instrumentation.Runtime from 1.12.0 to 1.13.0 (#1856) --- updated-dependencies: - dependency-name: OpenTelemetry.Instrumentation.Runtime dependency-version: 1.13.0 dependency-type: direct:production update-type: version-update:semver-minor ...

"""Sample: Handoff workflow with return-to-previous routing enabled.
|
||||
|
||||
This interactive sample demonstrates the return-to-previous feature where user inputs
|
||||
route directly back to the specialist currently handling their request, rather than
|
||||
always going through the coordinator for re-evaluation.
|
||||
|
||||
Routing Pattern (with return-to-previous enabled):
|
||||
User -> Coordinator -> Technical Support -> User -> Technical Support -> ...
|
||||
|
||||
Routing Pattern (default, without return-to-previous):
|
||||
User -> Coordinator -> Technical Support -> User -> Coordinator -> Technical Support -> ...
|
||||
|
||||
This is useful when a specialist needs multiple turns with the user to gather
|
||||
information or resolve an issue, avoiding unnecessary coordinator involvement.
|
||||
|
||||
Specialist-to-Specialist Handoff:
|
||||
When a user's request changes to a topic outside the current specialist's domain,
|
||||
the specialist can hand off DIRECTLY to another specialist without going back through
|
||||
the coordinator:
|
||||
|
||||
User -> Coordinator -> Technical Support -> User -> Technical Support (billing question)
|
||||
-> Billing -> User -> Billing ...
|
||||
|
||||
Example Interaction:
|
||||
1. User reports a technical issue
|
||||
2. Coordinator routes to technical support specialist
|
||||
3. Technical support asks clarifying questions
|
||||
4. User provides details (routes directly back to technical support)
|
||||
5. Technical support continues troubleshooting with full context
|
||||
6. Issue resolved, user asks about billing
|
||||
7. Technical support hands off DIRECTLY to billing specialist
|
||||
8. Billing specialist helps with payment
|
||||
9. User continues with billing (routes directly to billing)
|
||||
|
||||
Prerequisites:
|
||||
- `az login` (Azure CLI authentication)
|
||||
- Environment variables configured for AzureOpenAIChatClient (AZURE_OPENAI_ENDPOINT, etc.)
|
||||
|
||||
Usage:
|
||||
Run the script and interact with the support workflow by typing your requests.
|
||||
Type 'exit' or 'quit' to end the conversation.
|
||||
|
||||
Key Concepts:
|
||||
- Return-to-previous: Direct routing to current agent handling the conversation
|
||||
- Current agent tracking: Framework remembers which agent is actively helping the user
|
||||
- Context preservation: Specialist maintains full conversation context
|
||||
- Domain switching: Specialists can hand back to coordinator when topic changes

Handoff Workflow with Return-to-Previous Routing
|
||||
============================================================
|
||||
|
||||
This interactive demo shows how user inputs route directly
|
||||
to the specialist handling your request, avoiding unnecessary
|
||||
coordinator re-evaluation on each turn.
|
||||
|
||||
Specialists can hand off directly to other specialists when
|
||||
your request changes topics (e.g., from technical to billing).
|
||||
|
||||
Type 'exit' or 'quit' to end the conversation.
|
||||
|
||||

the reset. They'll be able to help troubleshoot and resolve this issue.

|

to your credit card on autopay.
|
||||
|
||||
You will receive updates from the appropriate teams shortly.
|
||||
>>> [technical_support]: Thanks for letting me know about your modem issue! To help you further, could you tell me:
|
||||
|
||||
1. Is there any light showing on the modem at all, or is it completely off?
|
||||
2. Have you tried unplugging the modem from power and plugging it back in?
|
||||
3. Do you hear or feel anything (like a slight hum or vibration) when the modem is plugged in?
|
||||
|
||||
Let me know, and I'll guide you through troubleshooting or arrange a repair if needed.
|
||||
|
||||
You: exit
|
||||
|
||||
Ending conversation. Goodbye!
