If we want to pass this on for messages, we'd need this to change in Svelte, Solid and Vue useChat as well.

feat: sync DurableAgent with latest workflow repo changes
8eca783
Sync changes from vercel/workflow packages/ai/src/agent since Jan 30
(PR #12165 creation date):
- Add telemetry support via recordSpan wrapper around model.doStream()
and new telemetry.ts module with OTel span recording
- Add normalizeFinishReason for cross-version compatibility (v5 string
vs v6 { unified, raw } object)
- Fix prepareStep ordering: messages applied before system so system
message isn't lost when messages replaces the prompt (#1389)
- Make DurableAgentOptions generic: tools/toolChoice properly typed
- Add prepareStep to DurableAgentOptions constructor for default
step preparation across all stream() calls
- Add TelemetrySettings.recordInputs/recordOutputs options
- Add InferDurableAgentTools/InferDurableAgentUIMessage type helpers
- Update sendStart docstring explaining when to set false
- Pass telemetry through to executeTool calls

feat: sync DurableAgent with latest workflow repo changes (#13774)
f741eb4
## Summary
Syncs DurableAgent code with changes from
[vercel/workflow](https://github.com/vercel/workflow/tree/main/packages/ai/src/agent)
since PR #12165 was opened (Jan 30, 2026). Key workflow PRs
incorporated:
- [#1362](vercel/workflow#1362) — AI SDK v6
migration, compat tests
- [#1385](vercel/workflow#1385) — Various
compatibility fixes
- [#1389](vercel/workflow#1389) — Fix
prepareStep system message lost when messages also returned
- [#1329](vercel/workflow#1329) — Client-side
tools support
## Changes
- **Telemetry**: Add `recordSpan` wrapper around `model.doStream()` with
OTel span attributes (provider, model, generation settings). New
`telemetry.ts` module with lazy OTel API loading.
- **`normalizeFinishReason`**: Handle both v5 string (`'stop'`) and v6
object (`{ unified: 'stop', raw: 'stop' }`) finish reason formats
- **prepareStep ordering fix**: Apply `messages` override before
`system` so the system message isn't lost when messages replaces the
prompt
- **Generic `DurableAgentOptions<TTools>`**: Tools and toolChoice
properly typed through the generic parameter
- **Constructor `prepareStep`**: New field on `DurableAgentOptions` for
default step preparation across all `stream()` calls
- **`TelemetrySettings`**: Add `recordInputs`/`recordOutputs` options
- **Type helpers**: Export `InferDurableAgentTools` and
`InferDurableAgentUIMessage`
- **`sendStart` docs**: Explain when to set `false` (custom pre-stream
UIMessageChunks)
- **Telemetry threading**: Pass telemetry settings through to
`executeTool` calls
## Test plan
- [x] `pnpm type-check` — zero production code errors
- [x] `pnpm check` — lint passes
- [x] `pnpm build` in packages/durable-agent — builds
- [x] `pnpm test:node` in packages/durable-agent — 60 passed, 22
expected fail (same as before)

feat: sync DurableAgent with latest workflow repo changes
8eca783
Sync changes from vercel/workflow packages/ai/src/agent since Jan 30
(PR #12165 creation date):
- Add telemetry support via recordSpan wrapper around model.doStream()
and new telemetry.ts module with OTel span recording
- Add normalizeFinishReason for cross-version compatibility (v5 string
vs v6 { unified, raw } object)
- Fix prepareStep ordering: messages applied before system so system
message isn't lost when messages replaces the prompt (#1389)
- Make DurableAgentOptions generic: tools/toolChoice properly typed
- Add prepareStep to DurableAgentOptions constructor for default
step preparation across all stream() calls
- Add TelemetrySettings.recordInputs/recordOutputs options
- Add InferDurableAgentTools/InferDurableAgentUIMessage type helpers
- Update sendStart docstring explaining when to set false
- Pass telemetry through to executeTool calls

feat: sync DurableAgent with latest workflow repo changes (#13774)
f741eb4
## Summary
Syncs DurableAgent code with changes from
[vercel/workflow](https://github.com/vercel/workflow/tree/main/packages/ai/src/agent)
since PR #12165 was opened (Jan 30, 2026). Key workflow PRs
incorporated:
- [#1362](vercel/workflow#1362) — AI SDK v6
migration, compat tests
- [#1385](vercel/workflow#1385) — Various
compatibility fixes
- [#1389](vercel/workflow#1389) — Fix
prepareStep system message lost when messages also returned
- [#1329](vercel/workflow#1329) — Client-side
tools support
## Changes
- **Telemetry**: Add `recordSpan` wrapper around `model.doStream()` with
OTel span attributes (provider, model, generation settings). New
`telemetry.ts` module with lazy OTel API loading.
- **`normalizeFinishReason`**: Handle both v5 string (`'stop'`) and v6
object (`{ unified: 'stop', raw: 'stop' }`) finish reason formats
- **prepareStep ordering fix**: Apply `messages` override before
`system` so the system message isn't lost when messages replaces the
prompt
- **Generic `DurableAgentOptions<TTools>`**: Tools and toolChoice
properly typed through the generic parameter
- **Constructor `prepareStep`**: New field on `DurableAgentOptions` for
default step preparation across all `stream()` calls
- **`TelemetrySettings`**: Add `recordInputs`/`recordOutputs` options
- **Type helpers**: Export `InferDurableAgentTools` and
`InferDurableAgentUIMessage`
- **`sendStart` docs**: Explain when to set `false` (custom pre-stream
UIMessageChunks)
- **Telemetry threading**: Pass telemetry settings through to
`executeTool` calls
## Test plan
- [x] `pnpm type-check` — zero production code errors
- [x] `pnpm check` — lint passes
- [x] `pnpm build` in packages/durable-agent — builds
- [x] `pnpm test:node` in packages/durable-agent — 60 passed, 22
expected fail (same as before)

feat: sync DurableAgent with latest workflow repo changes
8eca783
Sync changes from vercel/workflow packages/ai/src/agent since Jan 30
(PR #12165 creation date):
- Add telemetry support via recordSpan wrapper around model.doStream()
and new telemetry.ts module with OTel span recording
- Add normalizeFinishReason for cross-version compatibility (v5 string
vs v6 { unified, raw } object)
- Fix prepareStep ordering: messages applied before system so system
message isn't lost when messages replaces the prompt (#1389)
- Make DurableAgentOptions generic: tools/toolChoice properly typed
- Add prepareStep to DurableAgentOptions constructor for default
step preparation across all stream() calls
- Add TelemetrySettings.recordInputs/recordOutputs options
- Add InferDurableAgentTools/InferDurableAgentUIMessage type helpers
- Update sendStart docstring explaining when to set false
- Pass telemetry through to executeTool calls

feat: sync DurableAgent with latest workflow repo changes (#13774)
f741eb4
## Summary
Syncs DurableAgent code with changes from
[vercel/workflow](https://github.com/vercel/workflow/tree/main/packages/ai/src/agent)
since PR #12165 was opened (Jan 30, 2026). Key workflow PRs
incorporated:
- [#1362](vercel/workflow#1362) — AI SDK v6
migration, compat tests
- [#1385](vercel/workflow#1385) — Various
compatibility fixes
- [#1389](vercel/workflow#1389) — Fix
prepareStep system message lost when messages also returned
- [#1329](vercel/workflow#1329) — Client-side
tools support
## Changes
- **Telemetry**: Add `recordSpan` wrapper around `model.doStream()` with
OTel span attributes (provider, model, generation settings). New
`telemetry.ts` module with lazy OTel API loading.
- **`normalizeFinishReason`**: Handle both v5 string (`'stop'`) and v6
object (`{ unified: 'stop', raw: 'stop' }`) finish reason formats
- **prepareStep ordering fix**: Apply `messages` override before
`system` so the system message isn't lost when messages replaces the
prompt
- **Generic `DurableAgentOptions<TTools>`**: Tools and toolChoice
properly typed through the generic parameter
- **Constructor `prepareStep`**: New field on `DurableAgentOptions` for
default step preparation across all `stream()` calls
- **`TelemetrySettings`**: Add `recordInputs`/`recordOutputs` options
- **Type helpers**: Export `InferDurableAgentTools` and
`InferDurableAgentUIMessage`
- **`sendStart` docs**: Explain when to set `false` (custom pre-stream
UIMessageChunks)
- **Telemetry threading**: Pass telemetry settings through to
`executeTool` calls
## Test plan
- [x] `pnpm type-check` — zero production code errors
- [x] `pnpm check` — lint passes
- [x] `pnpm build` in packages/durable-agent — builds
- [x] `pnpm test:node` in packages/durable-agent — 60 passed, 22
expected fail (same as before)
