Install
With your agent
Install OMGSkills skill "juliusbrussee/caveman:caveman-stats" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/JuliusBrussee/caveman /tmp/caveman && ln -s /tmp/caveman/skills/caveman-stats ~/.claude/skills/caveman-statsFrom README
In Claude Code, src/hooks/caveman-mode-tracker.js resolves src/hooks/caveman-stats.js next to itself and runs it on /caveman-stats. The hook does not block the prompt: it supplies the report through hookSpecificOutput.additionalContext with an instruction to print it verbatim inside a fenced code block. Do exactly that, and do not calculate, recompute or re-round the numbers yourself. In Gemini CLI, direct the user to /stats model for current session token or /stats session for session statistics. Gemini custom commands are prompts; they cannot invoke the built-in command or read its live session metrics. Never read Claude Code transcripts as Gemini . In other hosts, use a native report if one is available; otherwise say that current session is unavailable. The Claude reader and its lifetime history apply only to Claude Code. Savings remain unknown in every host without a measured comparison.
