Chisle

Your AI talks less, builds less, reads less, and says more. Like a senior dev who bills by the syllable.

The only tool in this class that publishes the runs where it lost. Here's why.

On Pi + GPT-5.5, answers 37% the length of the same model with no ruleset (caveman 56%, ponytail 49%) · 12 agents · zero dependencies · one command

Chisle is a ruleset and hook pack that makes AI coding agents cheaper to run. It cuts what the model writes (no filler, no hedging, no speculative abstractions: the smallest code that works) and what it reads (oversized tool output is trimmed before it re-enters the context window). One `npx chisle` wires it into Claude Code, Pi, Cursor, Codex, Gemini, Copilot, OpenCode, Antigravity and four more agents. Every number below comes from committed raw transcripts, including the runs where it lost.
