@​mastra/agent-builder@​0.2.6-alpha.1

Patch Changes

• Fix install step validation error by making targetPath optional in InstallInputSchema. This resolves the "expected string, received undefined" error when running the agent builder template workflow without explicitly providing a targetPath parameter. (#10923)

Dependency Updates

• @​mastra/core@​0.24.7-alpha.3

---

@​mastra/ai-sdk@​0.3.3-alpha.0

Patch Changes

• Return NetworkDataPart on each agent-execution-event and workflow-execution-event in network streams (#10979)

• Fixed tool-call-suspended chunks being dropped in workflow-step-output when using AI SDK. Previously, when an agent inside a workflow step called a tool that got suspended, the tool-call-suspended chunk was not received on the frontend even though tool-input-available chunks were correctly received. (#10988)

  The issue occurred because tool-call-suspended was not included in the isMastraTextStreamChunk list, causing it to be filtered out in transformWorkflow. Now tool-call-suspended, tool-call-approval, object, and tripwire chunks are properly included in the text stream chunk list and will be transformed and passed through correctly.

  Fixes #10978

1.16.5

Patch Changes

• Fixed token metrics losing model labels and cost data when providers return blank response model IDs. (#20742)

• Updated dependencies [8d2399b, c8002da, 92be47f, 89200ba, c950138, 810c7e7, 063c8b2, f9f9884, e0904dc, 9672fab, f4e964c, 1f7bbd7, e47ff36, 64d6781, fb9a6ac, aa2cec8, c848e65, 2adf8eb, 0494489, 8d1aeb8, 8264611, d8fa243, 44fc98b, f933ba3, 83065bf, 0f2ef41, 01b162f]:

  • @​mastra/core@​1.57.0

1.16.4

Patch Changes

• Fixed logs and metrics emitted outside of a span (for example server request logs) being stored without an environment or service name. They now inherit the Mastra-level environment (from the environment config option or NODE_ENV) and the configured service name, so filtering by environment in Studio Observability no longer hides these logs and metrics. Relates to mastra-ai/mastra#19870 (#19892)

• Told bridges when a span ends without being exported, so they can free its state. (#20463)

  A span dropped by excludeSpanTypes, a spanFilter, or a span output processor emits no span-end event, so bridges such as @mastra/otel-bridge and @mastra/datadog never learned the span was finished and held the state they created for it until shutdown. Those spans now trigger a releaseSpan call on the bridge instead.

  Export behavior is unchanged: filtered spans are still not exported, and trace structure is untouched.

  Fixes #20368.

• Fixed RequestContext serialization to skip excluded spans and use its span-safe representation for exported traces. (#20231)

• Updated dependencies [4844167, c5e56ff, 594f7b2, 7f4e26d, 311f943, 322daa6, db4e6ff, 5faf93f, 82201f7, cadaa13, 0c89896, 6d19a65, 23b4238, 80ad891, fb18da5, fb18da5, e320a76, 03b4918, 14ef73a, b582f7f, 0a6598b, 06000d7, 1d677d5, 9e1dad8, 2f43145, 4e35a56, d94b8e1, 93e28ec, 729dab4, 484003d, 3de0188, 34d34d8, b582f7f, 933d291, a1cb98d, 598ad82, 1fd6aad]:
