v1.1.6 · 2026-04-29​

Summary​

  • Helix fixes duplicate sub-agent tool-call rendering when a child session dialog is open, adds a test for the guard, and improves the QEMU data-directory setup on Windows.
  • Helix-agent adds read_file tool-name alias for LLM compatibility, improves OpenAI streaming deduplication, and synthesizes missing reasoning tokens for tool calls.

Helix​

  • Fixed: Mirrored longterm_tool_call and longterm_tool_result events from the manager session are now suppressed while the child session's own WebSocket stream is connected, preventing duplicate tool step rendering in the sub-session dialog.
  • Fixed: QEMU data-directory startup notifier is now mirrored in the helix-vmd web stub so non-IO builds surface directory errors correctly on Windows.
  • Fixed: Data-directory child directories are pre-created before spawning the managed process; path separators are trimmed and unwritable paths surface a clear error.
  • Improved: QEMU setup guide surfaces optionalfeatures.exe launch errors so users see actionable feedback during WHPX acceleration setup.

Helix-agent​

  • Added: read_file is now accepted as an alias for the canonical read-file tool so LLMs that call the underscored form do not get a "tool not found" error.
