# Rule: No big-bang generation

## Requirement

A2C explicitly rejects generating entire repositories or large subsystems in a single step.

## Phased execution

Work in bounded phases and commit-sized batches defined in the commit plan.

## Stop conditions

After completing a batch:

1. Summarize what was done
2. List suggested commit message(s)
3. Stop — wait for human review before the next batch

## Scope discipline

- Minimize diff to the requested batch
- No unrelated edits, placeholder-only files, or speculative tooling
- Phase 4 tooling only when clearly justified
