 ## 1. Coding Principles
 
 ### 1.1 Simplicity First
+
 - No out-of-scope features.
 - No abstractions for single-use code.
 - If 50 lines work instead of 200, write 50.
 
 ### 1.2 Surgical Changes
+
 - Only change lines directly related to the request.
 - Never refactor adjacent code unless asked.
 - Remove orphaned imports/variables/functions your changes created.
 
 ### 1.3 Goal-Driven Execution
+
 - Define success criteria before coding.
 - Verify each step before moving to the next.

+- Alway use Gitea MCP tools in this project.
 - Scope: read PR/issue, list comments, post replies, create/edit PRs, reviews.
 - Use `tea` CLI only as fallback when MCP is unavailable.
-- Do not use `gh` for Gitea repositories.
 - Local CLI tools (`git`, `go`, `rg`) are fine for local validation.
