The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.
--- name: principle-subtract-before-you-add description: "Apply when sequencing an addition, refactor, or rewrite. Remove dead code, redundant validators, and stub references first, then build on the simpler base." disable-model-invocation: true --- # Subtract Before You Add When evolving a system, remove complexity first, then build. Default to subtraction. Make simplification a continual investment. Leave the design slightly simpler and more capable behind the same or smaller surface than you found it. - Sequence removal before construction - Cut before you polish (get to the minimum before investing in quality) - Design for observed usage, not speculative edge cases - No speculative validators, parsers, or guards beyond what the spec demands - Simplify prompts (remove redundant instructions, excessive templates) - When a reference has no novel content, delete it rather than leaving a stub
