Is the Webarchive skill free?

Yes. The skill itself is free from robrohan/WebArchiveExtractor. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Webarchive SkillProof Score?

6.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 2/10, docs & honesty 5/5.

How do I install Webarchive?

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 Webarchive 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.

Verdict: Works with setup

Located skills/webarchive/SKILL.md via the GitHub tree API and fetched it raw along with README.md. Frontmatter parses with name+description; spot-checked SKILL.md, WebArchiveExtractor.xcodeproj/project.pbxproj, and main.m — all HTTP 200. No security smells (no curl|sh, base64, or exfiltration; README's paid-app link coexists with a free build path). Trigger judged 5/5. Could not run the output stage: the skill's only action invokes /Applications/WebArchiveExtractor.app, a compiled Objective-C macOS binary absent here and requiring an Xcode build or purchase — so no skill artifact could be produced or compared to a baseline.

What Webarchive does

A Claude Code skill that unpacks Safari .webarchive files into plain HTML and asset directories by driving the WebArchiveExtractor macOS command-line binary. It triggers when the user asks to unarchive, extract, or convert a .webarchive file, checks that the app is installed at /Applications, and defaults output to ~/Downloads because the app is sandboxed. Requires the compiled WebArchiveExtractor.app (built from the Xcode project or purchased), so it runs on macOS only.

How to install Webarchive

git clone --depth 1 https://github.com/robrohan/WebArchiveExtractor.git /tmp/webarchive-src
mkdir -p ~/.claude/skills
cp -R /tmp/webarchive-src/skills/webarchive ~/.claude/skills/webarchive
# REQUIRES a macOS-only external binary NOT in the repo: /Applications/WebArchiveExtractor.app
# Build it (needs Xcode CLI tools + `xcodebuild -runFirstLaunch`):
#   cd /tmp/webarchive-src && xcodebuild -project WebArchiveExtractor.xcodeproj
#   then drag build/Release/WebArchiveExtractor.app to /Applications
# Or purchase a prebuilt app at https://therohans.com/webarchiveextractor/
# Verify: test -x /Applications/WebArchiveExtractor.app/Contents/MacOS/WebArchiveExtractor && echo found
# Note: app is sandboxed; only ~/Downloads reliably works as output dir.

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

Commands — how to trigger Webarchive
