Claude Code debugging needs fresh sessions

The takeaway is less about “AI pride” and more about session bias: once an agent has committed to a faulty mental model, it tends to keep defending it. A clean session acts like a second opinion, which is exactly what messy multi-file codebases need.

• –Same-session debugging can lock Claude Code into its own prior assumptions, especially after several back-and-forth edits
• –A fresh session reduces conversational inertia and forces the model to re-read the repo from the current state
• –The pattern suggests a practical workflow: build in one session, verify or debug in another
• –It’s anecdotal, but the failure mode matches what developers already see with humans and tools alike: context can become a liability when it is too sticky
