[Bug] Claude Code making unverified claims and false positive issue detection

**Bug Description**
Claude Code became very sloppy the past week or so. Claims things without verifying. Finds issues for problems that do not exist / we shouldn't care about yet.

**Environment Info**
- Platform: darwin
- Terminal: iTerm.app
- Version: 2.1.259
- Feedback ID: 6bd3b7f5-d26c-416d-bd63-8785c7376fa9

No source files, tests, or entry points are named. Start by reproducing the behavior with Claude Code 2.1.259 on darwin in iTerm.app, using feedback ID 6bd3b7f5-d26c-416d-bd63-8785c7376fa9 and the reported API, symlink, and readlink errors; the report does not define a concrete completion check.
