Pi packages can execute code and influence agent behavior. Review the source before installing third-party packages.

A pi extension that adds /utree — a conversation view with the same UX as the built-in /tree, filtered down to just the conversation:

  user: Fix the bug in foo.ts
  assistant: Found it — fixing now.
  user: Thanks, also check bar.ts
› • assistant: Done, bar.ts is fine.

User statements and assistant text responses only
Thinking blocks, tool calls, tool results, and session bookkeeping entries are excluded
Chains of assistant messages within one turn (progress updates between tool calls) are collapsed to the final response, so the view alternates cleanly user → assistant → user → assistant

It reuses pi's own tree selector, so everything from /tree works:

↑/↓ move · ←/→ page
Type to search
Fold/unfold branch segments (ctrl+← / ctrl+→)
ctrl+x copy the selected message
Filter keys (ctrl+u for user-only, etc.) narrow further
Enter navigates the session to the selected point, including /tree's Summarize branch? prompt (Esc returns to the tree)

In non-interactive mode (pi -p), /utree prints the collapsed transcript to stdout instead.

pi install npm:pi-utree

or from git:

pi install git:github.com/andrewprock/pi-utree

shift+l label editing is display-only here: extensions get a read-only session manager and cannot persist label changes (use /tree for that).
The header says "Session Tree" — that string is shared with the built-in /tree component.
