v0.26.3

What’s New in v0.26.3

Features

• Agent-created persistent threads — agents can now use threads_create to create an independent thread, immediately queue its initial prompt, and inherit or override the caller’s working directory and project context. The tool returns the new thread identity without waiting for its work to finish. (#395)

Improvements

• The agent tool contract rejects empty prompts and supports explicitly clearing project assignment with projectId: null.
• Public documentation now separates agent thread creation from the existing human Fork command and /fork workflow.

Notes

• The human Fork workflow, modal, conversation summarization, and /fork command remain unchanged.
• No migration or configuration changes are required.
