Section 1
The premise
AI can flag wire-compat risks and draft migration PRs, but the wire-compat rules need to be in the prompt.
What AI does well here
- Check field-number reuse and tag-collision risk.
- Draft proto changes with backward-compat comments.
- Generate test fixtures that cross schema versions.
What AI cannot do
- Know which old binaries are still in production.
- Detect compatibility issues from required-to-optional shifts in older proto2 code.
