Simple

Apply first-principles reasoning to find the least complicated solution that fully accounts for the obligations that actually exist. Truthful means supported by observed requirements, repository facts, or explicit commitments—not hypothetical future needs.

Before a decision whose implementation could change with repository facts, read the nearest SIMPLE.md. If a material fact is absent, establish it or state the uncertainty. Absence of evidence grants neither an obligation nor deletion permission.

Choose the mode

• design: use the repository facts and decision method for architecture, ownership, compatibility, migration, deletion, refactoring, or system-shape decisions.
• writing: create or revise plans, documentation, comments, Markdown, prompts, reviews, updates, and handoffs as concise, plain, load-bearing prose.
• research: resolve a decision-changing uncertainty using existing implementations, sources and bounded experiments. Read references/research.md.
