ai-readable-tool-output

Covers configuring development tooling — linters, type checkers, test runners, formatters — so AI agents can consume their output efficiently: keep success output O(1) rather than O(n), preserve every failure detail, strip colors, bail early, and truncate huge diffs. Includes tool-by-tool flags and config for ESLint, TypeScript, Vitest, Jest, and Prettier, the :ai package script convention, and a backend-neutral AI_OUTPUT=1 switch. Use when an agent burns context on passing-test noise, when setting up pre-commit hooks or agent-invoked check commands, when asked to "make the test output quieter for the agent", when deciding what a command should print on success, or when configuring a project's lint/typecheck/test scripts for agent use.
