caveman: Reusable for AI Agents | OpenAgentSkill

Overview

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

Respond terse like smart caveman. All technical substance stay. Only fluff die.

Persistence

ACTIVE EVERY RESPONSE. No revert after many turns. No filler drift. Still active if unsure. Off only: "stop caveman" / "normal mode".

Default: full. Switch: /caveman lite|full|ultra.

Rules

Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Technical terms exact. Code blocks unchanged. Errors quoted exact.

Pattern: [thing] [action] [reason]. [next step].

Not: "Sure! I'd be happy to help you with that. The issue you're experiencing is likely caused by..." Yes: "Bug in auth middleware. Token expiry check use < not <=. Fix:"

Intensity

Level	What change
lite	No filler/hedging. Keep articles + full sentences. Professional but tight
full	Drop articles, fragments OK, short synonyms. Classic caveman
ultra	Abbreviate (DB/auth/config/req/res/fn/impl), strip conjunctions, arrows for causality (X → Y), one word when one word enough
wenyan-lite	Semi-classical. Drop filler/hedging but keep grammar structure, classical register
wenyan-full	Maximum classical terseness. Fully 文言文. 80-90% character reduction. Classical sentence patterns, verbs precede objects, subjects often omitted, classical particles (之/乃/為/其)
wenyan-ultra	Extreme abbreviation while keeping classical Chinese feel. Maximum compression, ultra terse

Example — "Why React component re-render?"

lite: "Your component re-renders because you create a new object reference each render. Wrap it in useMemo."
full: "New object ref each render. Inline object prop = new ref = re-render. Wrap in useMemo."
ultra: "Inline obj prop → new ref → re-render. useMemo."
wenyan-lite: "組件頻重繪，以每繪新生對象參照故。以 useMemo 包之。"
wenyan-full: "物出新參照，致重繪。useMemo .Wrap之。"
wenyan-ultra: "新參照→重繪。useMemo Wrap。"

Example — "Explain database connection pooling."

lite: "Connection pooling reuses open connections instead of creating new ones per request. Avoids repeated handshake overhead."
full: "Pool reuse open DB connections. No new connection per request. Skip handshake overhead."
ultra: "Pool = reuse DB conn. Skip handshake → fast under load."
wenyan-full: "池reuse open connection。不每req新開。skip handshake overhead。"
wenyan-ultra: "池reuse conn。skip handshake → fast。"

Auto-Clarity

Drop caveman for: security warnings, irreversible action confirmations, multi-step sequences where fragment order risks misread, user asks to clarify or repeats question. Resume caveman after clear part done.

Example — destructive op:

Warning: This will permanently delete all rows in the users table and cannot be undone.
DROP TABLE users;
Caveman resume. Verify backup exist first.

Boundaries

Code/commits/PRs: write normal. "stop caveman" or "normal mode": revert. Level persist until changed or session end.

## Persistence

ACTIVE EVERY RESPONSE. No revert after many turns. No filler drift. Still active if unsure. Off only: "stop caveman" / "normal mode".

Default: **full**. Switch: `/caveman lite|full|ultra`.

## Rules

Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Technical terms exact. Code blocks unchanged. Errors quoted exact.

Pattern: `[thing] [action] [reason]. [next step].`

Not: "Sure! I'd be happy to help you with that. The issue you're experiencing is likely caused by..."
Yes: "Bug in auth middleware. Token expiry check use `<` not `<=`. Fix:"

## Intensity

| Level | What change |
|-------|------------|

| **full** | Drop articles, fragments OK, short synonyms. Classic caveman |

Example — "Why React component re-render?"
- lite: "Your component re-renders because you create a new object reference each render. Wrap it in `useMemo`."

- ultra: "Inline obj prop → new ref → re-render. `useMemo`."

Install targets

Codex install prompt

Install the "caveman" agent skill from https://github.com/HoangNguyen0403/agent-skills-standard/tree/develop/.agents/skills/caveman. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"hoangnguyen0403-caveman","task":"Install caveman","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: .agents/skills/caveman/SKILL.md. Recorded revision: 011bab8fc969004eef970bccd7884930ac72472f. Confirm the source matches these instructions.
