What problem does it solve? Setting up a game-development environment often involves guesswork about installed engines, GPU capabilities, and tool versions, leading to broken installs and conflicting configurations. This Skill diagnoses the local toolchain without changing anything, then produces a single reversible setup proposal. ## Core Features & Use Cases - Read-Only Environment Inventory: Detects OS, architecture, WSL status, disk space, GPU backend, VRAM, and network constraints without launching or modifying tools. - Engine and Tool Detection: Inspects installed Unity, Godot, Unreal, Blender, Aseprite, Pixelorama, and Tiled versions plus Python, Node.js, Git, and MCP declarations without reading credential values. - Reversible Transaction Proposal: Returns one setup transaction with exact version pins, licenses, downloads, conflicts, backups, rollback operations, and a no-change attestation. - Use Case: Before installing a new asset-generation pack, run this Skill to confirm your Godot version, GPU VRAM, and Node.js setup meet the pack's constraints, then review the proposed transaction before approving any change. ## Quick Start Use the toolchain-doctor skill to inspect this project's OS, engines, GPU, and MCP setup and propose a reversible setup plan without changing anything.
