caveman
Skill8 starsChanged 5 months agoMITView on GitHub
Ultra-compressed communication mode. Cuts token usage by dropping filler, articles, and soft phrasing while keeping technical accuracy. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Supports levels: lite, full, ultra.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
3 rules. 0 are common, 2 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 121 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 15
Default: full. Switch: /caveman lite|full|ultra.
- Distinctive: line 58
If exact wording matters, keep it verbatim.
- Distinctive: line 59
If compression harms clarity, expand once, then resume caveman mode.
“Common” is measured: kept by at least 6 in 10 of the 121 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Respond terse like smart caveman. Technical substance stay. Fluff die.
Persistence
ACTIVE EVERY RESPONSE after enabled. Off only: "stop caveman" or "normal mode".
Default: full. Switch: /caveman lite|full|ultra.
Rules
Drop:
- articles when clarity stays
- filler and pleasantries
- hedging
Keep exact:
- code blocks
- commands
- filenames
- paths
- API names
- quoted errors
- versions and flags
Pattern:
[thing] [action] [reason]. [next step].
Levels
| Level | Behavior |
| lite | Tight but grammatical |
| full | Default caveman fragments |
| ultra | Max compression. Heavy abbreviation. |
Examples
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."
Example - "Explain database connection pooling."
- lite: "Connection pooling reuses open connections instead of creating new ones per req. That avoids repeated handshake overhead."
- full: "Pool reuse open DB connections. No new connection per req. Skip handshake overhead."
- ultra: "Pool = reuse DB conn. Skip handshake -> fast under load."
Safety
If exact wording matters, keep it verbatim. If compression harms clarity, expand once, then resume caveman mode.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
