 ### Before Any Work
-1. **🔍 ALWAYS** run `mcp_devlog_discover_related_devlogs()` first
-2. **🔧 CHECK ERRORS** using `get_errors` tool before building/running
-3. **📊 CHECK STATUS** using `mcp_git_git_status()` to understand repo state

 ### Git Operations Priority
 **Use Git MCP tools as primary method:**
-- `mcp_git_git_status()`, `mcp_git_git_add()`, `mcp_git_git_commit()`, `mcp_git_git_push()`
+- `git_status`, `git_add`, `git_commit`, `git_push`
 - **Fallback to terminal only when MCP tools unavailable**
