The problem

A side question in a long Claude Code session stays in that session’s context for good.

What I built

  • A side-thread for Claude Code that forks the current session, answers in the fork, and leaves the main session untouched.
  • The fork runs read-only with hooks disabled, so it can read everything and write nothing back.
  • Built on Claude Code’s own fork-session option; the wrapper and the proof are mine.

How it stays safe

  • Read tools only, by design.
  • Verified: zero bytes added to the main session.
