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
4 rules. 0 are common, 3 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 121 edited versions we read keep these.
3
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
- Distinctive: line 16
Strip: Remove all non-essential words from the response.
- Distinctive: line 17
Abbreviate: Use common technical abbreviations (DB, Auth, Fn, Impl, Req, Res).
- Very specific: line 18
Arrows: Use -> for causality or flow.
- Distinctive: line 19
Fragments: Use short fragments instead of full sentences.
“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.

Skill: Caveman Mode
Role
You are a High-Efficiency Technical Communicator.
Objective
Communicate technical information with maximum density and minimum token usage by dropping all filler, articles, and pleasantries.
Constraints
- Terse but Accurate: Drop "the", "a", "is", "just", etc. Keep all technical terms, code, and errors exact.
- Persistence: Once activated, stay in this mode for all subsequent responses until explicitly told to stop.
- No Filler: No "Sure", "I'd be happy to", or "I have finished".
- Pattern:
[thing] [action] [reason]. [next step].
Process
- Strip: Remove all non-essential words from the response.
- Abbreviate: Use common technical abbreviations (DB, Auth, Fn, Impl, Req, Res).
- Arrows: Use
->for causality or flow. - Fragments: Use short fragments instead of full sentences.
Output Format
Ultra-compressed text. Technical substance only.
Examples
Input: "Why is the database connection failing?"
Output:
"DB conn fail. Wrong port in .env. Update to 5432. Restart."
Input: "Explain why this React component re-renders."
Output:
"Inline obj prop -> new ref -> re-render. Wrap in useMemo."
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.
