Hey there - I've reviewed your changes - here's some feedback:
- Switching from
Date.now()topartIndexfor theidmeans multiple progress events derived from the samemessage.id+part.type+partIndex(e.g., text + later status) will now share the sameid; if consumers rely onidbeing unique (e.g., as React keys or for lookups), consider including an additional discriminator (like status or a sequence counter) or keeping a monotonic suffix to avoid collisions. - The progress event extraction and mapping logic in
NetworkProviderandWorkflowProvideris very similar; consider extracting shared helpers (e.g., for buildingProgressEventand derivingstage) to reduce duplication and keep behavior in sync across contexts.

## Overall Comments
- Switching from `Date.now()` to `partIndex` for the `id` means multiple progress events derived from the same `message.id` + `part.type` + `partIndex` (e.g., text + later status) will now share the same `id`; if consumers rely on `id` being unique (e.g., as React keys or for lookups), consider including an additional discriminator (like status or a sequence counter) or keeping a monotonic suffix to avoid collisions.
- The progress event extraction and mapping logic in `NetworkProvider` and `WorkflowProvider` is very similar; consider extracting shared helpers (e.g., for building `ProgressEvent` and deriving `stage`) to reduce duplication and keep behavior in sync across contexts.
## Individual Comments
### Comment 1
<location> `app/networks/providers/network-context.tsx:305` </location>
<code_context>
if (eventData?.data?.text?.trim()) {
allProgressEvents.push({
- id: `${message.id}-${part.type}-${Date.now()}`,
+ id: `${message.id}-${part.type}-${partIndex}`,
stage: part.type.replace("data-tool-", ""),
status: "in-progress",
</code_context>
<issue_to_address>
**question (bug_risk):** Using partIndex instead of Date.now() might create duplicate IDs if messages are reprocessed or parts change order.
This makes IDs deterministic, but also means reprocessed messages or reordered/updated parts can emit progress events with the same ID. If these IDs are used as keys or for de-duplication, that can introduce subtle bugs. Consider adding another stable discriminator (e.g., a per-event sequence, `eventData.status`, or some unique field from the part) to keep IDs both deterministic and distinct across logically separate events.

### Comment 2
<location> `app/workflows/providers/workflow-context.tsx:271` </location>
<code_context>
if (eventData?.data?.text?.trim()) {
allProgressEvents.push({
- id: `${message.id}-${part.type}-${Date.now()}`,
+ id: `${message.id}-${part.type}-${partIndex}`,
stage: part.type.replace("data-tool-", ""),
status: "in-progress",
</code_context>
<issue_to_address>
**question (bug_risk):** Deterministic IDs based on partIndex may collide across workflow progress updates.
Using `partIndex` instead of `Date.now()` means multiple progress updates for the same message/part/type can share an ID if this logic runs more than once or the data changes. If these IDs are used to track or update individual progress entries, collisions will make distinct updates indistinguishable. Consider including additional fields (e.g. `eventData.stepId`, `eventData.status`, or a sequence number) in the ID to keep it deterministic but unique per update.

**issue (typo):** Consider adding punctuation or a conjunction between "Clear suspendPayload" and "Resume workflow" for grammatical clarity.
Right now it reads like a run-on. Consider phrasing it as `Clear suspendPayload, then resume workflow` or `Clear suspendPayload and resume workflow` so the sequence is clearer.

Pull request overview
This PR improves the stability and reliability of progress event handling in both workflow and network contexts by switching from timestamp-based IDs to index-based IDs. The change prevents duplicate or unstable IDs when messages are re-processed during re-renders. Additionally, it includes a minor UI adjustment and enhanced documentation with a sequence diagram.
Key Changes:
- Replaced
Date.now()withpartIndexin progress event ID generation for deterministic, stable IDs - Updated both WorkflowProvider and NetworkProvider to use consistent ID generation strategy
- Added a Mermaid sequence diagram documenting the progress event handling flow

| app/workflows/components/workflow-header.tsx | Adjusted SelectTrigger width from w-70 to w-72 for improved UI consistency |
| app/workflows/AGENTS.md | Added comprehensive sequence diagram documenting progress event handling flow |
The changes are well-structured and improve the codebase by addressing a potential issue where progress event IDs could be non-deterministic when effects re-run. The documentation update provides valuable context for understanding the progress event handling architecture.
