Use the developer-stack-skills MCP server before editing any file: 1. Call `detect_stack` with the file path to identify the relevant stack. 2. Call `get_skill` with the detected stack to load its conventions. 3. Do not preload all skill files — load only the relevant skill on demand. For cross-cutting decisions, call `get_conventions` to load project-wide standards. After loading the relevant skill, create a concise implementation plan, state assumptions, then implement.
