 # Manual Slop - OpenCode Configuration
 
+## MCP TOOL PARAMETERS - CRITICAL
+- **ALWAYS use snake_case**: `old_string`, `new_string`, `replace_all`
+- **NEVER use camelCase**: `oldString`, `newString`, `replaceAll`

 ## Project Overview
 
 **Manual Slop** is a local GUI application designed as an experimental, "manual" AI coding assistant. It allows users to curate and send context (files, screenshots, and discussion history) to AI APIs (Gemini and Anthropic). The AI can then execute PowerShell scripts within the project directory to modify files, requiring explicit user confirmation before execution.
