# Parameter :: 24. `show_tree::`
Show agent sessions tree-indented under their root session.
**Type:** Boolean
**Fundamental Type:** Boolean
**Default:** `0`
**Commands:** `.projects`
**Purpose:** When set to `1`, switches `.projects` session display from compact family-summary format (v1) to tree-indented format — each agent session appears indented under its root session with `├─`/`└─` connectors, full UUID, and per-session entry count. Replaces the former `verbosity::2` behavior.
Default (0): compact format — root session shown with short UUID, mtime, entry count, and inline agent summary `[N agents: breakdown]`.
**Examples:**
```bash
show_tree::0 # Default — compact family summary per root session
show_tree::1 # Tree-indented agents under root sessions
```
