The short answer

  1. To update, run the install command again. It replaces the skill’s whole folder with the current version.
  2. Lookbk installs the current version only, so copy the folder somewhere safe before you update. That copy is how you roll back.
  3. To remove a skill, delete its folder. To keep it but stop it running, switch it off in your agent.

Update a skill

There is no separate update command. Running add again deletes the skill’s folder and writes the current version, then prints the version it installed. Run it once for each way you installed the skill: once for your home folder, and once with --project for each repository.

  1. Step 1: See which version you have

    The skill’s page shows its current version and the date it was last updated. The version on disk is in the license file the download carries.

    Terminal
    grep '"version"' ~/.agents/skills/<skill>/.lookbook/license.json

  2. Step 2: Copy the folder aside

    Do this first if you might want the old version back. See the next section.

  3. Step 3: Run the installer again

    Terminal
    curl -fsSL https://lookbk.dev/cli.js | node - add <skill>
curl -fsSL https://lookbk.dev/cli.js | node - add <skill> --project

  4. Step 4: Start a new agent session

    The installer reminds you to. Agents that watch their skills folders may pick the change up sooner, but a fresh session is the sure way.

A single-skill purchase includes updates for 12 months. Pro includes updates while your plan is active. Founding Lifetime covers every current and future Pro skill. Copies you already downloaded stay licensed to you if a plan ends, but new downloads and updates stop.

Roll back to the version you had

Lookbk installs the current version of a skill and keeps no older ones to install, so a roll back needs a copy you made. Put it outside every skills folder. Agents read all the folders on their list, so a copy left inside one can load as a second skill with the same name.

Before you update
mkdir -p ~/skill-backups
cp -R ~/.agents/skills/<skill> ~/skill-backups/<skill>-<version>
To go back
rm -rf ~/.agents/skills/<skill>
cp -R ~/skill-backups/<skill>-<version> ~/.agents/skills/<skill>
  • The same works for ~/.claude/skills, and for the .agents/skills and .claude/skills folders in a project.
  • A ZIP you downloaded is a backup too. A single-skill purchase is a permanent license to the version you download, so keep the ZIP of a version you like.
  • If you committed the skill to a repository, git diff shows what an update changed and git restore puts back any file you want.

Remove a skill

Delete the skill’s folder from each place it lives. Nothing else is installed on your computer.

Terminal
rm -rf ~/.agents/skills/<skill> ~/.claude/skills/<skill>
rm -rf .agents/skills/<skill> .claude/skills/<skill>   # if you used --project
What to do after deleting the folder
AgentAfter you delete it
Claude CodeIt drops the skill from /skills in the current session.
CodexIt detects the change. Restart Codex if the skill still shows.
CursorIt finds skills when it starts, so restart it.
GitHub CopilotRun /skills reload. copilot skill remove <name> also deletes the files.
Gemini CLIRun /skills reload.
OpenCodeStart a new session.

Keep it, but switch it off

To stop a skill running without deleting it, switch it off in your agent. You keep the files and can switch it back on.

How to switch a skill off, by agent
AgentHow
Claude CodeType /skills, highlight the skill and press Space to change its visibility, then Esc to save. To stop only automatic use, set disable-model-invocation: true in its header.
CodexAdd a [[skills.config]] entry with enabled = false to ~/.codex/config.toml, then restart Codex.
CursorSet disable-model-invocation: true in the header, so it runs only when you type its name. Cursor’s docs show no way to switch one off entirely.
GitHub Copilot CLIcopilot skill disable <name>, or /skills, then choose Disable.
Gemini CLI/skills disable <name>. It applies to your user scope unless you add --scope workspace.
OpenCodeSet the skill’s permission to deny in opencode.json. That hides it from the agent.

To sign out of Lookbk on this computer, run the installer with logout. It ends the session on the server and deletes the saved sign-in.

Common questions

Will updating delete my files?
Yes, any you put inside the skill’s own folder, because the installer deletes that folder first. Files in your project folder are untouched.
How do I know a newer version exists?
The skill’s page shows its current version and the date it was last updated. Compare that with the version in .lookbook/license.json in your copy.
What happens to my skills if my Pro plan ends?
Copies you downloaded while subscribed stay licensed to you. New downloads and updates stop.

Safety checks before running a skill

A skill is instructions and code your agent may run. Six checks to make first: its source, its commands, its network use and what it may do without asking.

Where skills live: folders for every agent

The folders each agent reads skills from, which copy wins when two share a name, and what cloud agents can see.
