caveman-help shows a short reference card when you type /caveman-help or say "caveman help". The card lists the three modes (caveman, ultracave, megacave), the commit, review and compress skills, how to turn caveman off, and how to set the default mode.

It is a one-shot: SKILL.md says it must not change mode, write flag files or persist anything. It bundles no scripts. It is only useful if you use the other caveman skills.

Questions

What does caveman-help do?

It prints a short reference card for the caveman skills: the modes, the commands and how to change the default mode. It does not change any setting.

How do I install caveman-help?

Use the install box at the top of this page. It is one folder with SKILL.md and a README, so a skills-folder install is enough.

Is caveman-help useful on its own?

Not really. It describes the other caveman skills and modes. Install the main caveman package if you want those; this card then tells you the commands.

How do I turn caveman off?

Say "stop caveman" or "normal mode". Per the card, type /caveman to turn it on again.

How do I change the default mode?

The card names two ways: set the CAVEMAN_DEFAULT_MODE environment variable, or put defaultMode in ~/.config/caveman/config.json. The environment variable wins if both are set.

Is caveman-help safe?

It bundles no scripts and the SKILL.md says it must not write flag files or persist anything. On skills.sh the audits read Gen Agent Trust Hub pass, Socket pass and Snyk pass.
