… After investigation, we identified three different issues: On March 4, we changed Claude Code's default reasoning effort from high to medium to reduce the very long latency—enough to make the UI appear frozen—some users were seeing in high mode. …
… Combined with faster median latency and strict instruction following, it’s particularly meaningful for complex, long-running coding workflows. …
… In a world where agents read everything, the investigation tooling is also an attack surface. …
… This produces better results on harder problems, but can add cost and latency on simpler ones. …
… This solves the core issue, but adds orchestration complexity, token overhead, and latency to each harness run. …
