focused on project decisions the agent cannot reliably infer from nearby code or tooling. Instruction loading differs by harness; verify which root and nested files apply before counting their context cost.
Use short, concrete rules with emphasis reserved for costly violations. A command or example earns space when it prevents an actual ambiguity. Optimize the total material loaded for representative tasks, not line count alone or moving an unconditional full read into a reference.
Done when the requested scope has one clear owner per rule, no unresolved policy contradiction, and proportionate validation. Report what changed and any remaining limitations without creating a recurring audit ritual.
