incremental-implementation

Breaks large or multi-file implementation work into small verified slices that keep the project working after each step. Use when building a feature, bugfix, refactor, migration, integration, UI flow, or operational change that could become a large diff; when more than one file/module is touched; when scope is fuzzy; when review or rollback would be hard; when Codex is tempted to code for a long time before testing; or when the user asks to work in small verified steps, slices, маленькими проверяемыми шагами, по шагам с проверкой, or после каждого шага проверяй.
