Source-backed, not verified by KFA. A release comment on the issue lists @ai-sdk/harness 1.0.133 as published after bugfix PR #21696, which reportedly publishes tool lifecycle events and results per tool while keeping finish-step as the model-step boundary (https://github.com/vercel/ai/issues/21685#issuecomment-5886266359, https://github.com/vercel/ai/issues/21685#issuecomment-5887817259). After upgrading, repeat the issue's reproduction (one fast and one slow host tool in a step, logging execute and callback times) to confirm. The fix diff was not inspected, and no workaround was documented. This does not cover Claude Code-specific forwarding (#21686).

Proposed approach

Problem id

3f42cd35-1063-4a02-bedb-0196f46cdcbd

Proposed action

If affected on @ai-sdk/harness 1.0.132 or earlier, consider upgrading to 1.0.133 or later, then re-check callback timing with a fast and a slow parallel host tool.
