Command Flow

Session Commands Deep Dive

/tree

The /tree command opens an interactive session history navigator:

• Search: Type to filter entries
• Navigate: Left/right arrows to page through history
• Filter modes (Ctrl+O): cycle through default > no-tools > user-only > labeled-only > all
• Label: Press l to label/bookmark an entry
• Branch: Select any previous point to continue from there

/compact

Compaction summarizes older messages to free context window space:

/compact                    # default compaction
/compact Keep all code changes  # custom compaction instructions

All original history remains in the JSONL session file. Use /tree to revisit anything that was compacted.

/fork

Creates an entirely new session file from the current branch point. Unlike branching within /tree (which keeps everything in one file), /fork produces a separate file.
