Six practical ways to debug agents that fail silently

Six debugging patterns for agents that “break and you never know why”
This Reddit thread is a practical checklist for making agent behavior observable and debuggable.
- Verify whether the expected tool call actually happened, rather than assuming it did.
- Check output shape: did the agent return the exact typed object you expected?
- Confirm side effects in the filesystem and database, including whether transactions really landed.
- Track agent configuration over time, including the exact version and commit hash used for each run.
- The author argues that a full configuration history could make regressions and quality changes much easier to diagnose.
The overall theme is that agent reliability comes from traceability: if you cannot reconstruct what happened, you cannot fix it.
