README

Caveman for pi

License: MIT pi package Version

Ultra-compressed communication mode for pi: fewer tokens, same technical substance.

pi-caveman packages the original JuliusBrussee/caveman response style as a native pi package. Install it, and every agent response becomes shorter by default.

Why

Coding agents often spend tokens on polite filler. Caveman mode removes filler while preserving exact technical meaning.

Before: Sure! I'd be happy to help. The issue is likely caused by...
After: Bug in auth middleware. Token expiry check use `<` not `<=`. Fix:

Features

  • Always-on caveman response style while package is installed
  • No commands, per-session state, config, or toggles
  • Short system prompt injected before every agent turn

Install

pi install @viartemev/pi-caveman

Package layout

extensions/caveman.ts       # pi extension adapter + compact mode prompts
skills/caveman              # caveman response-style skill
package.json                # pi package manifest

How it works

The pi extension hooks into:

  • before_agent_start — injects compact active-mode rules every turn

The base caveman skill is exposed by package.json; the extension makes the style always active.
