What

Infrastructure for recording terminal sessions in asciicast v2 format (.cast files).

Status

Internal infrastructure — no user-facing command to enable or control recording.

Details
  • Monkey-patches process.stdout.write to capture all terminal output with timestamps
  • Recordings stored under ~/.claude/projects/<project>/ as .cast files
  • Supports flushing and renaming recordings for session management
  • File permissions set to owner read/write only (mode 384)
Evidence

Recording infrastructure (search for "[asciicast] Recording to", "[asciicast] Renamed recording")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
