Field notes
Decision records are small JSON files committed next to the code, with a schema example showing a check against a JSON pointer and expected value. The page says invalid records stop checks, and that plugins deny tool calls if the checker cannot run. It lists Claude Code, opencode, and pi integrations as verified live; Codex is explicitly marked as awaiting a live check.
