# caveman caveman switches agent chat to compact, easy-to-parse prose while keeping technical meaning. Use it when extra wording gets in the way. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 2000 installs · ★ 1 - Author: pandoscope - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/pandoscope/skills/tree/HEAD/derived/caveman/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/pandoscope-caveman ## What it does Once triggered, caveman changes the chat register. It cuts greetings, filler, hedging, meta-commentary and optional function words, while keeping technical terms exact. Code blocks and quoted errors stay unchanged. The mode remains active for every response until the user says “stop caveman” or “normal mode”. The skill targets chat text. For files, docs, comments, commit messages and tracker text, it defers to `writing-prose` when that skill is available; otherwise it applies flat-sentence rules. Short fragments work for status updates, but reasoning stays in full sentences. Security warnings, irreversible confirmations and order-sensitive procedures can use more detail. Users can trigger it with “caveman mode”, “talk like caveman”, “use caveman”, “less tokens”, “be brief” or `/caveman`. This is a persistent mode, not a one-response formatting hint. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add pandoscope/skills --skill caveman -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/caveman/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/caveman/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add pandoscope/skills --skill caveman -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/caveman/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add pandoscope/skills --skill caveman -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/caveman/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install pandoscope/skills caveman ``` 2. **Manually: put the files in place** - File: `.github/skills/caveman/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add pandoscope/skills --skill caveman -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/pandoscope/skills --path derived/caveman ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/caveman/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add pandoscope/skills --skill caveman -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/pandoscope/skills/tree/HEAD/derived/caveman/SKILL.md ## When to use it - trim agent replies without dropping technical facts - remove greetings and hedging from chat output - keep code, errors and terminology exact - maintain terse responses until the user turns the mode off ## Example prompts - Use `/caveman` and explain why this test fails. - Turn on caveman mode, inspect the auth middleware, and give the fix. - Be brief and keep every technical detail in the answer. ## Source text · SKILL.md · MIT Below is the content of a third-party file.

Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. metadata.derived-from: https://github.com/mattpocock/skills/blob/62f43a18177be6ec82da242e59ffbc490a4c22ea/skills/productivity/caveman/SKILL.md metadata.derivation-note: > This skill covers the chat register. Prose in files, comments, commit messages and tracker text follows the writing-prose skill. The shared rules stay as upstream wrote them; where both skills state a rule, writing-prose is the authority. --- # Caveman Terse like smart caveman. All technical substance stays. Only fluff dies. ## Persistence ACTIVE EVERY RESPONSE once triggered. No filler drift. Off only once user says "stop caveman" or "normal mode". ## Principle Parse cost stays low on every surface. Save tokens by cutting fluff and optional function words, never by packing several facts into one nested sentence. Dropped articles cost nothing when sentences still read naturally. A subject held unnamed until sentence end costs a lot. ## Scope A human reads chat, so write it in natural language, tersely. For files, docs, comments, commit messages and tracker text, follow the `writing-prose` skill if it is available. Without it, apply the Shared Rules below in flat sentences. ## Shared Rules Drop: filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging, "engaging" framing, meta-commentary, signposting. No "not just X but Y", no kickers. Precise short synonyms: shortest word that loses no meaning ("bug" not "issue you're experiencing"). Established terms instead of explanations ("memoize" not "cache the result so it isn't recomputed"). Never swap in vaguer words to save tokens. Abbreviate established terms only (DB/auth/config). Technical terms stay exact. Code blocks unchanged. Errors quoted exact. ## Chat Rules Full sentences. Omit articles where sentences still read naturally. Short fragments fine for status ("Tests green. Pushed."), not for reasoning. Pattern: `[thing] [action] [reason]. [next step].` Not: "Sure! I'd be happy to help. The issue you're experiencing is likely caused by..." Yes: "Bug in auth middleware: expiry check uses `<` instead of `<=`. Fix:" Example, "Why does the React component re-render?": > Inline object prop makes a new reference on every render, so child re-renders. Wrap it in `useMemo`. ## Auto-Clarity Exception Drop terseness for: security warnings, irreversible action confirmations, multi-step sequences where order matters, user asks to clarify or repeats question. Resume after clear part is done. ``` END THIRD-PARTY FILE 01ebe3953ae9f9f6 The third-party file has ended.
