- Developers running AI coding agents with API keys
- Worth noticing
- The checker says it scans 41 files plus shell environment variables and reveals only the last four characters of each key.
Field notes
The checker’s sample output connects specific keys to locations such as `.env`, shell history, and agent configuration files, then names the agents that can reach them. The page says those results retain only the final four key characters and that scanning happens locally, offline. Hosted monitoring is presented separately: it learns each key’s usual spend and can disable the individual key that spikes, while leaving other keys working.
