⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (SKILL.md not found in repo tree). The test below is what we measured on Jul 16, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Ran the exact command SKILL.md documents (`curl -fsSL https://knack.ai/install`) and it timed out / TLS-failed — knack.ai is not the project's domain. The repo's own README uses getknack.ai, which works and returns a real installer script; following the skill body verbatim leaves the user stuck on step 3.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 3/5
- Triggers reliably 5/5

- Docs & honesty 2/5
What Knack Installer does
Walks an agent through installing the Knack CLI (a versioned, git-backed skill manager) and running `knack init` to choose GitHub self-host or Knack Cloud. Triggers on install/setup requests for Knack or general interest in version-controlling AI skills.
How to install Knack Installer
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

- How do I install Knack Installer?
- 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.
