laconic is a 300 word skill for AI coding agents inspired by caveman.
It cuts filler. It keeps meaning. It trusts context.
Every word earns its place.

Caveman Benchmark
Claude Sonnet 4 via Langdock API. Each prompt: generic system prompt vs full laconic SKILL.md. Median of 3 runs per mode.

|---|---|---|---|---|
| Explain React re-render bug | 885 | 68 | 92% | +5pp |
| Fix auth middleware token expiry | 1059 | 39 | 96% | +13pp |
| Set up PostgreSQL connection pool | 2167 | 189 | 91% | +7pp |
| Explain git rebase vs merge | 996 | 95 | 90% | +32pp |

| Implement React error boundary | 4096 | 400 | 90% | +3pp |
| Average | 1547 | 139 | 90% | +25pp |
Range: 75%–96% savings across prompts. Caveman benchmarks averaged 64%.
[!IMPORTANT] Laconic cuts output tokens only.

Examples
Prompt: "My Express auth middleware is letting expired JWT tokens through. The expiry check uses Date.now() compared to the token's exp field. What's wrong and how do I fix it?"
🗣️ Normal (~1,300 tokens)Explains JWT spec, Unix timestamps vs JavaScript milliseconds, walks through middleware architecture, adds error handling, suggests libraries, and outputs a full refactored file (...) |
Λ Laconic (19 tokens)

Caveman vs Laconic
| Caveman | Laconic | |
|---|---|---|
| Tone | Primitive | Terse |
| Explanation | Normal | Trusts context, skips what reader knows |
| Code | Normal | Just enough code |
| Token savings | ~65% | ~90% |
