v1.1.13

Features

• Plan Mode: Added Claude Code-style Plan Mode (setup_plan / PlanToolSet), so agents can enter a design-and-approval phase before implementation. Supports model-initiated entry via enter_plan_mode and user/UI-driven entry through session state, with plan drafting (update_plan_content), clarifying questions, approval gating (exit_plan_mode), and write-tool restrictions while planning.
• Tools: Added Tavily as a provider for WebSearchTool and WebFetchTool. Search can return LLM-ready answers plus optional image hits; fetch can use Tavily Extract as an alternative to direct HTTP fetching.
• AG-UI: Expanded long-running tool discovery so nested ToolSet tools (including Plan Mode tools) are recognized during AG-UI runs, and tool names can be resolved from session history when the client payload only carries a tool call id.

Bug Fixes

• AG-UI: Fixed session state updates from the AG-UI protocol not being persisted. State-change events are now appended as non-partial events so session services apply them correctly.
• Runner: Avoided repeated string concatenation while accumulating streaming partial text. Partial chunks are kept as a list and joined only when cancellation cleanup needs the full text.
• Examples: Fixed a few example agents (LangGraph and Mem0) so the full example pipeline can run more reliably.

Docs

• Docs: Added English and Chinese Plan Mode guides, plus dedicated pages for TodoWrite, Task, and Goal tools.
• Docs: Documented Tavily configuration and usage for web search and web fetch.
• Examples: Added plan_mode and plan_mode_with_goal_and_task AG-UI examples for trying Plan Mode end to end.

Internal

• CI: Added a GitHub Actions release workflow for publishing releases.
• CI: Added code-review helper prompts and scripts under .github/code_review/.
• CI: Added pipeline_test/run_all_examples.sh to drive the full examples pipeline more consistently.
