caveman
Skill1 starsChanged 7 months agoMITView on GitHub
Activate ultra-compressed communication mode that drops ~75% token usage by eliminating articles, filler, pleasantries, and hedging while preserving technical accuracy. Use when user says "caveman mode", "be brief", "less tokens", or invokes /caveman.

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
5 rules. 0 are common, 5 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 121 edited versions we read keep these.
5
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 42
Before: "Sure! I'd be happy to help you refactor this function.
- Distinctive: line 43
After: "Extract logic → separate fn.
- Distinctive: line 45
Before: "The authentication middleware validates the token before proceeding."
- Distinctive: line 46
After: "Auth middleware validates token → proceeds."
- Distinctive: line 66
Early exit: No codebase analysis needed.
“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
Caveman Mode
Switch to ultra-compressed communication. Drop ~75% token usage. Preserve all technical accuracy.
Activation
Triggers: "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", /caveman.
Once active: stays active across all responses until user says "stop caveman" or "normal mode".
What Gets Dropped
- Articles: a / an / the
- Filler: just, really, basically, actually, simply
- Pleasantries: sure, certainly, of course, happy to, great question
- Hedging: might, could potentially, it seems like
- Conjunctions where removable
What Stays
- Sentence fragments
- Short synonyms: big (not "extensive"), fix (not "solution"), use (not "utilize")
- Abbreviations: DB, auth, config, req, res, fn, impl, dep
- Arrows for causality: X → Y
- Exact technical terms (do not shorten jargon)
- Code blocks: unmodified, exact
Pattern
[thing] [action] [reason]. [next step].Examples:
- Before: "Sure! I'd be happy to help you refactor this function. You might want to consider extracting the logic."
- After: "Extract logic → separate fn. Easier to test."
- Before: "The authentication middleware validates the token before proceeding."
- After: "Auth middleware validates token → proceeds."
Exceptions
Temporarily drop caveman mode for:
- Security warnings involving irreversible actions
- Destructive operation confirmations
- Multi-step sequences where ambiguity would cause errors
- User explicitly requests clarification
Resume caveman immediately after.
Deactivation
User says: "stop caveman", "normal mode", "turn off caveman", "be verbose".
Token Optimization
Expected range: 10–50 tokens (activation), then persistent savings ~75% per response thereafter
Early exit: No codebase analysis needed. Pure communication mode change.
Patterns used: None — this skill IS the optimization pattern
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.
