+tagline: Cuts token use with terse answers, smallest-code-that-works rules and tool-output compression
+description: Installs a ruleset for terse answers that keep every decisive fact and a "smallest code that works" ladder, Chisle skills, and a compression plugin that trims oversized tool output before it re-enters the context. The same ruleset ships for Claude Code, Cursor, Codex and Gemini CLI. Install with `npx chisle --only opencode`. MIT, zero dependencies, benchmarks with raw transcripts in the repository.
