Skill Installerとは
One-click install AI Agent Skills from GitHub into Claude Code and other coding agents. Preview, pin to a commit, update safely. The missing install button for Agent Skills.
Skill Installer finds AI Agent Skills (SKILL.md) on the pages you already browse — GitHub repos, awesome-lists and skill marketplaces — shows you exactly what they do, and installs them into every AI coding agent you use. One click. No terminal, no copy-paste.
INSTALLS WHERE YOUR AGENTS ALREADY LOOK
- The universal skills folder (~/.agents/skills) — the shared location coding agents have standardised on, so one install reaches all of them
- Claude Code's own folder (~/.claude/skills)
- Any other folder you point it at
- Or install into a project instead (.claude/skills, .agents/skills), so the skill travels with the repository and can be committed
- Tick any combination — a single click writes to all of them at once
FINDS SKILLS WHERE YOU BROWSE
- GitHub repos and folders are detected automatically — including collections that bundle many skills
- Awesome-lists: hundreds of linked skills get an ⚡ install badge, each verified before it's offered
- Skill marketplaces work out of the box, and any other page can be scanned on demand from the popup

REVIEW BEFORE ANYTHING LANDS
- Preview the instructions, frontmatter and full file list before installing
- Bundled scripts and pre-approved tool grants are flagged in plain language
- Every file is fetched pinned to an exact git commit and checksum-verified
- Nothing executes at install time — a skill is files in a folder, nothing else
ONE COMMAND TO SET UP, THEN ONE CLICK FOREVER
- A browser extension can't write to your disk, so a small local helper does. One command sets it up — macOS, Windows and Linux, no admin rights
- It never runs in the background: your browser starts it per request and it exits immediately
- One command takes it away again, straight from the extension's settings — your installed skills stay exactly where they are
- Skipping it entirely is fine — detection and the full preview still work, and each skill offers a copy-paste install command instead
STAYS UP TO DATE
- Installed skills remember the exact commit they came from
- Update checks watch each skill's own commit history and show you what changed before you update
- Clean uninstall from a receipt — nothing else in your folders is ever touched
PRIVATE BY DESIGN
- No account. No telemetry. Zero analytics.
- Talks only to GitHub and the pages you visit
- The helper writes only inside the folders you approved, in your home directory
Agent Skills are reusable instruction packs that teach AI agents new workflows — reading and editing PDFs and Office documents, reviewing code, scaffolding projects, automating your stack. Skill Installer makes adding them to your AI agents as easy as installing this extension. Installing MCP servers and subagents from the same button is on the roadmap.
Get started: install, open any skills repo on GitHub, and click the pill. Website: https://skillinstaller.com
