title: Gitea Dev - Native Mode Optimized
author: Jeff Smith + Claude + minimax + kimi-k2
version: 1.4.0
license: MIT
description: Interact with Gitea repositories - native tool calling optimized for high-tier LLMs with robust error handling
requirements: pydantic, httpx
changelog:
  1.4.0:
    - Added CRUD operations for Issues (get, update, close, reopen, delete, comments)
    - Added CRUD operations for Pull Requests (get, update, merge, comments)
  1.3.0:
    - Native Mode optimization with explicit tool schemas
    - Added mapping protocol support to Valves/UserValves (__iter__, keys, __getitem__)
    - Enhanced __init__ for framework-driven configuration injection
    - Added self.citation = True for tool usage visibility
    - Robust error handling with detailed context in responses
    - Structured context returns for better LLM understanding
    - Added to_dict() helper methods on valve classes
