Is the WSL Interop skill free?

Yes. The skill itself is free from JeremiahChurch/claude-skill-wsl-interop. SkillProof publishes the install command and an independent test verdict at no cost.

What is the WSL Interop SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 4/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install WSL Interop?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use WSL Interop with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 8.8/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 03cbd47

The README itself admits automatic triggering is unreliable for ordinary phrasing like 'where's my file?' and recommends forcing it via a CLAUDE.md directive — testing my own trigger judgment confirmed exactly that gap on an ambiguous no-path-mentioned query, while explicit-path and explicit-SSH-agent phrasings triggered cleanly. On the actual Windows-drive-path task, the skill correctly avoided the broken clickable-link mistake (no file:// URI works for /mnt/c/ paths) and used the documented 'show C:\ path, offer to open via cmd.exe' pattern instead — a baseline answer without the skill would likely have tried to construct a link that doesn't work.

What WSL Interop does

Single-file skill covering the Windows/WSL boundary: wslpath conversion rules, exact clickable file:// URI formatting for WSL-native vs Windows-drive paths, ssh.exe/clip.exe interop, and fixes for sed -i, CRLF, and /mnt/ permission quirks. Triggers on Windows-formatted paths, WSL file references the user may want to open, and WSL-specific troubleshooting (SSH agent, Docker Desktop, network access).

How to install WSL Interop

mkdir -p ~/.claude/skills/wsl-interop
git clone https://github.com/JeremiahChurch/claude-skill-wsl-interop.git /tmp/wsl-interop-src
cp /tmp/wsl-interop-src/SKILL.md ~/.claude/skills/wsl-interop/SKILL.md

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
