+Execute Python code with a persistent IPython kernel and 30+ shell-like helpers:
+
+- **Streaming output**: Real-time stdout/stderr with image and JSON rendering
+- **Prelude helpers**: `cat()`, `sed()`, `rsed()`, `find()`, `grep()`, `batch()`, `sh()`, `run()` and more
+- **Git utilities**: `git_status()`, `git_diff()`, `git_log()`, `git_show()` for repository operations
+- **Line operations**: `extract_lines()`, `delete_lines()`, `insert_lines()`, `lines_matching()` for text manipulation
+- **Shared gateway**: Resource-efficient kernel reuse across sessions (`python.sharedGateway` setting)
+- **Custom modules**: Load extensions from `.omp/modules/` and `.pi/modules/` directories
+- **Rich output**: Supports `display()` for HTML, Markdown, images, and interactive JSON trees
+- Install dependencies via `omp setup python`

 - CLI args (`--smol`, `--slow`) and env vars (`OMP_SMOL_MODEL`, `OMP_SLOW_MODEL`)
 - Configure via `/model` selector with keybindings (Enter=default, S=smol, L=slow)
 
+## + Todo Tool (Task Tracking)
+
+Structured task management with persistent visual tracking:
+
+- **`todo_write` tool**: Create and manage task lists during coding sessions
+- **Persistent panel**: Todo list displays above the editor with real-time progress
+- **Task states**: `pending`, `in_progress`, `completed` with automatic status updates
+- **Completion reminders**: Agent warned when stopping with incomplete todos (`todoCompletion` setting)
+- **Toggle visibility**: `Ctrl+T` expands/collapses the todo panel
