- Developers relying on third-party JSON APIs
- Worth noticing
- Its sample flags `balance` changing from integer to string and leaves the ambiguous “1200” versus “12.00” interpretation to a human.
Field notes
The setup flow asks a coding agent to find external JSON APIs, draft a `tiltmeter.yaml`, add `.tiltmeter/` to `.gitignore`, and record baselines. The page also shows an MCP check that reports drift severity and changed fields. For proposed fixes, it says the agent can show a diff and open a pull request, while leaving ambiguous cases for human review.
