- Issues
- Add `VercelModel` surfacing the Vercel AI Gateway's reported `usage.cost` in `provider_details`
- `OpenAIChatModel` + `VercelProvider` drops the Vercel AI Gateway's reported `usage.cost`
- Agent `max_concurrency` hangs workflows under `TemporalDurability`
- Pass Temporal `deps` by reference (design spike)
- Add `max_tool_concurrency` to `Agent`
- An approver sees the model's original tool arguments, not the ones that will execute
- Temporal: allow passing `deps` by reference instead of serializing them into every activity dispatch
- Support Kimi K3 dynamic tool loading as a native `ToolAvailabilityDeltaPart` renderer
- Durable dynamic-tool schema errors retry engine units instead of prompting the model
- `override(tools=...)` is rejected inside a durable workflow or flow by accident, not by design
