v1.1.21

Features

• Memory: Split Advanced Memory into two independently configurable capabilities: Session Compact under trpc_agent_sdk.sessions.compact and long-term memory tools under trpc_agent_sdk.tools.advanced_memory. Session Compact now exposes common summarizer/manager abstractions, supports BEFORE_MODEL and AFTER_TURN triggers, and keeps the existing SessionSummarizer, SessionSummary, and SummarizerSessionManager exports as aliases for the default implementation. (#336)
• Memory: Added a standalone AdvancedMemory integration and AdvancedMemoryToolSet with explicit save_memory, read_memory, and list_memory_index tools, tenant/session-scoped storage resolution, bounded index injection, optional relevance-based preload, freshness metadata, and local, Redis, or SQL storage backends. (#336)
• Memory: Reworked advanced context compaction as a Session Service capability, retaining staged tool-result budgeting, history snipping, micro-compaction, token tracking, LLM auto-compaction, and structured session-memory extraction without requiring a session-service wrapper. Compressed raw events can be retained through SessionServiceConfig.store_historical_events, and summary anchors are preserved when limiting the model-facing history. (#336)
• Model: Added OpenAIModel.response_metadata_extractor for allowlisted, JSON-serializable fields returned by OpenAI-compatible providers. Extracted values are exposed under provider_response_metadata on the final LlmResponse and trace for Chat Completions and Responses API calls, including streaming responses. (#328)
• Skill: Added SkillToolSetWithDynamicTools and made skill-declared tool discovery optional, allowing applications to omit skill_list_tools / skill_select_tools when dynamic tool selection is not needed. Clarified that skill_list_tools lists tools declared by one skill rather than every tool available to the Agent. (#323)

Bug Fixes

• Code Execution: Prevented executable-code parts and fenced code found in model thinking content from being treated as code to run; only visible model output is now eligible for automatic execution. (#327)
• Storage: Fixed MySQL session timestamp comparisons losing microsecond precision by compiling database-generated timestamps as CURRENT_TIMESTAMP(6), while preserving the native now() behavior for PostgreSQL and SQLite. (#322)
• Sessions: Removed session summaries from system instructions so compressed context has a single model-facing source in session history, avoiding duplicated summary tokens and inconsistent behavior after process restarts. (#336)

Docs

• Memory: Added runnable Advanced Memory examples for local, Redis, and SQL long-term-memory storage, plus an advanced session summarizer example and updated configuration guidance. (#336)
• Model: Added English and Chinese documentation and a runnable example for extracting provider-specific response metadata. (#328)
• Skill: Updated English and Chinese Skill documentation and examples for static versus dynamic skill tool exposure. (#323)

Internal

• Memory: Removed the former trpc_agent_sdk.advanced_memory, AdvancedMemoryService, and AdvancedMemorySessionService layout in favor of the new Session Compact and standalone Advanced Memory APIs; applications importing those old paths should migrate to trpc_agent_sdk.sessions.compact and trpc_agent_sdk.tools.advanced_memory. (#336)
• Testing: Expanded coverage for Session Compact, summary retention across InMemory/Redis/SQL services, provider metadata extraction, thought-code execution safety, MySQL timestamp precision, and dynamic Skill tools.
