Shorter answers, compressed tool output and cheaper model routing, with code left exact.","summary":"Caveman makes coding agents say less and read less: terse answers, logs and JSON shrunk before the model reads them, compressed web pages, reusable scripts in code mode, and optional Auto model routing. The README reports 33.2% fewer input tokens across 54 Claude Code runs. One npx install (Node.js 22.13+) on Mac, Linux or Windows. Apache-2.0. The CLI sends usage stats by default (no prompts or code); Auto needs a free account and sends your asks to Caveman Cloud.","capabilities":["agent-skills"],"tags":["Agent skills","Claude Code","Codex","Gemini CLI","OpenCode","Needs paid AI plan","Token savings"],"alternatives":[],"facts":{"runs_locally":{"status":"yes","value":"Yes, the skill and CLI run on your machine with your own model keys or login","source_url":"https://github.com/JuliusBrussee/caveman#install","checked_at":"2026-10-23","confidence":"high","validation":"documentation_review","modes":["local"],"untrusted_source_quote":"It runs on your machine, with your keys and your Claude Pro/Max login."},"code_license":{"status":"yes","value":"Apache-2.0, whole repo","source_url":"https://github.com/JuliusBrussee/caveman#license","checked_at":"2026-10-23","confidence":"high","validation":"documentation_review","spdx":"Apache-2.0","untrusted_source_quote":"Apache-2.0, whole repo."},"model_license":{"status":"yes","value":"No bundled weights; uses your coding agent's model","source_url":"https://github.com/JuliusBrussee/caveman#install","checked_at":"2026-10-23","confidence":"high","validation":"documentation_review","spdx":null,"applies":false},"commercial_use":{"status":"yes","value":"Yes, Apache-2.0; \"Caveman\" and the logo are trademarks of the author","source_url":"https://github.com/JuliusBrussee/caveman#license","checked_at":"2026-10-23","confidence":"high","validation":"documentation_review","untrusted_source_quote":"Read it, fork it, ship it, host it."},"paid_services":{"status":"partial","value":"Needs a coding agent and its model (a paid plan or API key); Auto routing needs a free Caveman account","source_url":"https://github.com/JuliusBrussee/caveman#auto-54-cheaper-same-score","checked_at":"2026-10-23","confidence":"high","validation":"documentation_review","required":[],"optional":["Claude Pro/Max","ChatGPT","model API keys","Caveman account (free) for Auto"],"untrusted_source_quote":"Works in Claude Code, OpenCode, and Codex on a ChatGPT login, with API keys, Claude Pro/Max, or ChatGPT."},"hardware":{"status":"yes","value":"No hardware needs of its own; needs Node.js 22.13+ for the CLI","source_url":"https://github.com/JuliusBrussee/caveman#install","checked_at":"2026-10-23","confidence":"medium","validation":"documentation_review","cpu_ok":true,"min_vram_gb":null,"min_ram_gb":null,"untrusted_source_quote":"Needs Node.js 22.13+."},"platforms":{"status":"yes","value":"macOS, Linux and Windows","source_url":"https://github.com/JuliusBrussee/caveman#install","checked_at":"2026-10-23","confidence":"high","validation":"documentation_review","windows":"yes","macos":"yes","linux":"yes","untrusted_source_quote":"One command.
