Improved Code Review + Detection Mode
Our new Code Review pipeline finds more bugs at every severity, and Detection Mode lets each team choose how aggressively Macroscope flags issues.
We shipped a major upgrade to Macroscope's Code Review, along with a new setting that puts you in control of how it balances coverage and precision.
Improved bug detection
We launched a new version of Code Review that finds substantially more bugs. In our benchmarks it surfaces:
- 71% more critical issues
- 27% more high-severity issues
- 50% more medium-severity issues
- 31% more valid issues overall
This comes at the expense of a modest increase in false positives and review latency.
The new version is now the default for Code Review, and it is fully configurable with the new Detection Mode setting.
Detection Mode
Detection Mode is a new setting that lets you choose how Macroscope balances finding more bugs against minimizing noise. There are two options.
Prefer Coverage is optimized for maximum bug detection. You get higher coverage, an increase in overall comment volume, and a higher likelihood of false positives (85% precision in our benchmarks). We recommend it for teams that use coding agents to review and validate PR comments, since the cost of an occasional false positive is negligible when a local agent is doing the validation.
Prefer Precision prioritizes high-confidence findings. You get lower bug detection rates, but a lower likelihood of false positives (97% precision in our benchmarks). We recommend it for teams that primarily review comments manually in GitHub, where a false positive is more noticeable. This mode most closely mirrors the experience of the past couple of months.
Configure it your way
You can set Detection Mode at the repository level or at the individual developer level, with developer settings overriding repository defaults. For example, your repo could be set to "Prefer Precision" while an individual developer chooses "Prefer Coverage" for their own PRs.
No action required
For existing customers, no action is required. The improved detection is already live, and you can change your Detection Mode anytime in your settings.
