Get the plugin

git clone https://github.com/JuliusBrussee/caveman

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/caveman/.

Compatibility: the page URL and API slug “caveman-7” remain stable.

  • Codex: Legacy selector caveman-7@agent-plugin-marketplace remains documented for migration; install from source for this runtime.

This plugin's manifest name conflicts with another source for the same runtime. The source remains indexed, but this directory does not generate mismatched -2/-3 install commands.

Included Skills6

cavecrewskills/cavecrew/SKILL.md

When to delegate to `cavecrew-investigator` (locate code), `cavecrew-builder` (1-2 file edit) or `cavecrew-reviewer` (diff review) instead of working inline or using `Explore`. Their output is compressed, so main context lasts longer.

cavemanskills/caveman/SKILL.md

Terse caveman voice: answer first, fluff gone, every technical fact kept. Use for /caveman, "caveman mode", "talk like caveman", "be brief", "less tokens". Stays on until "stop caveman" or "normal mode".

caveman-compressskills/caveman-compress/SKILL.md

Compress a memory file such as CLAUDE.md or a todo list into caveman format to save input tokens, keeping a readable backup. Trigger: /caveman-compress.

caveman-statsskills/caveman-stats/SKILL.md

Show recorded output and cache-read token usage and mode attribution for the current Claude Code session, or locate the host's native usage report. Trigger: /caveman-stats.

megacaveskills/megacave/SKILL.md

Caveman in Classical Chinese: 文言文 register, far fewer characters, technical terms verbatim. Invoke only with /megacave or /caveman wenyan. Stays on until "stop caveman" or "normal mode".

ultracaveskills/ultracave/SKILL.md

Caveman at maximum compression: fragments, one word when one word is enough, each fact once. Invoke only with /ultracave or /caveman ultra. Stays on until "stop caveman" or "normal mode".
