- Worth noticing
- A protected-test example shows an agent weakening an assertion; Difftower flags changed protected files and can queue a restore request.
Field notes
The documented workflow starts by marking the repository state, then keeps the session’s changes visible as the agent edits and commits. The page describes protected-file rules stored in a repository-level .difftower.toml file, with alerts when those files change. It also gives an example of a test assertion weakened by an agent and says test commands can be discovered for pytest, vitest, and Rails.
