Release Notes
- Added a /skills reload subcommand to asynchronously reload discovered skills and slash commands without restarting the session or blocking user input.
- Added an inline argument autocomplete dropdown when typing /model and a live fuzzy search bar inside the interactive /model picker to filter models by name or ID.
- Improved authentication error messages when OAuth tokens lack required scopes by including explicit instructions to run /logout and /login.
- Fixed mid-conversation model switching to Gemini thinking models failing with thoughtsignature validation errors when prior turns were generated by non-Gemini models.
- Fixed web search (searchweb) failing with "no summary returned from GenerateContent" when the summarization model emits leading thought parts.
- Fixed agent turns terminating prematurely with NOTOOLCALL when a tool call fails schema validation, allowing the agent loop to return the validation error and self-correct.
- Fixed MCP tool schema augmentation mutating tool definitions in place, preventing strict argument validation failures.
- Fixed hooks.json configurations being silently dropped when customization token budget truncation is active.
- Fixed custom subagents losing configured exclude skill filters when runtime skill filtering is applied.
- Fixed subagent status and termination tracking under pubsub batch coalescing so killed subagents are not reset to active by late step updates.
- Fixed conversations with active turns or running daemon background tasks failing to auto-resume after a restart.
- Fixed terminal ERROR steps (such as failed tool executions or timeouts) being omitted from transcript.jsonl conversation logs.
- Fixed raw OSC 8 escape sequences rendering in AppleTerminal over SSH connections by disabling unsupported hyperlink sequences.
