🚀 Added

  • Web Crawl Tool – New crawl_website tool for comprehensive site-wide extraction (docs, knowledge bases, etc.) with depth control, path filtering, and natural language instructions.
  • GPT‑5.3 Codex Spark – Ultra-fast coding model now available via OpenAI Codex.
  • Claude Sonnet 5 – Added across Anthropic, CommandCode, and GitHub Copilot providers.
  • Ad‑hoc Skills Loading – Skills can now be discovered and registered at runtime without requiring pre‑existing skill files.
  • OAuth Lock for MCP – Prevents concurrent OAuth flows from conflicting on the same callback port during streaming server session creation.
  • Image Extraction in Web Fetch – The extract_webpage tool now returns up to 3 images as base64 data URIs alongside text content.
  • Cosine Distance for Memory – Switched to cosine distance metric in ChromaDB for improved memory retrieval quality.
  • Shrunk Context Argument Preview – Truncated tool call arguments now include a preview (e.g., tool_name(key=value...)) for better debugging.
  • Memory Similarity Score – Memory recall now shows similarity score in the header for transparency.

🔧 Changed

  • GitHub Copilot Models – Updated to latest model lineup (Claude Opus 4.8, Claude Fable 5, Gemini 3.5 Flash, MAI-Code-1-Flash, Kimi-K2.7-Code, GPT‑5.4 nano, etc.).
  • Web Search Tool Description – Simplified and clarified tool descriptions for better LLM understanding.
  • Tavily Extract Depth – Upgraded to advanced extraction depth for richer content.
  • Dependency Updates – tavily-python bumped to 0.7.26, chromadb to 1.5.9.
  • Memory Thresholds – Adjusted relevance thresholds for both default and Voyage embedding functions to improve recall precision.
  • Skills Service – SkillsService now always initializes even when no skills are found, enabling dynamic skill registration later.

🐛 Fixed

  • Context Consistency Between Modes – Fixed assistant message not being appended to history in certain agent loop exit paths, ensuring consistent context across different execution modes.
  • ACP Session Race Conditions – Added per‑session asyncio.Lock to serialize prompt, close_session, and cancel calls, preventing concurrent state corruption.
  • ChromaDB Collection Space – Automatically recreates collection with cosine space if it was previously using a different metric (e.g., l2), avoiding compatibility issues.
  • Task History Append – Corrected method call in A2A task execution to use the proper history reference.

📦 Version & Build

  • Version bumped from 0.17.6 → 0.18.0 in __init__.py, pyproject.toml, and Docker configuration.
