0.7.0 (2026-06-29)

⚠ BREAKING CHANGES

• sdk: Agents can now overwrite existing files with write_file instead of receiving a file-exists error. Workflows, prompts, tests, or guardrails that relied on that error to force edit_file usage or to protect existing content must add explicit permission/HITL checks or use edit_file when preserving existing content matters.
• sdk: Agents now see a destructive delete filesystem tool when the backend supports it. Existing agents may choose to remove files or directories recursively, and existing filesystem permission rules that allow writes can now authorize deletion unless a narrower deny or interrupt rule blocks the target subtree.
