What problem does it solve? Working across Windows and WSL2 often causes mixed-runtime drift, wasted tokens, and inconsistent tooling choices. This Skill provides a decision workflow that picks one primary runtime, the lowest-cost profile, and the right MCP server before work begins. ## Core Features & Use Cases - Runtime Routing: Classifies tasks as Windows-first, WSL2-first, or dual, then commits to one primary runtime to avoid mid-task switching. - Profile Selection: Maps tasks to cost-tiered profiles (lean, quick, deep, review, research, debug, design, automation) to control token usage. - MCP Guidance: Routes structured file IO to filesystem, library docs to context7, and browser automation to playwright or chrome-devtools, preferring plain shell when simpler. - Use Case: Before debugging a failing browser flow, use this Skill to choose WSL2 as the runtime, the debug profile, and chrome-devtools for network inspection. ## Quick Start Use the dual-environment workflow to decide the runtime, profile, and MCP path for this task before starting.
