            agent session disk usage

asdu shows where Antigravity (agy), Claude, Codex, Gemini CLI, Hermes, Kimi, OpenCode, and OMP sessions use disk space.

It works like a file browser. Start in a folder, inspect its sessions, and move up or down the directory tree. Everything stays local.

Install

Install with uv:

uv tool install asdu
asdu

On Windows, use CPython 3.11–3.14 in Windows Terminal. The required curses compatibility package is installed automatically. WSL continues to work normally.

Update an existing installation:

uv tool upgrade asdu

Use

Run asdu inside any project:

asdu

Start somewhere else:

asdu ~/

The initial view shows folders. Press g for one flat list, then sources of sessions in the current folder. Press t to show session trees; they open folded.

• Arrow keys select rows. In trees, ↑↓ select siblings and ←→ move between parents and children.
• Enter opens a folder or session brief.
• Backspace goes back or moves to the parent folder.
• / or Ctrl-F searches every scanned session by title, folder, or ID.
• g switches between folder, source, and all-session views.
• f filters by source.
• F filters by session type: main, child, review, or ? when unknown.
• s changes the sort order.
• t toggles trees. Space folds one branch and z folds or opens all.
• a shows the actions supported by the selected source.
• r rescans.
• q quits.

Text selection stays with your terminal. On terminals that support alternate scroll, the mouse wheel moves through the list while selection remains available.

Press ? for help. Run asdu --help for command-line options.

Session briefs

Press Enter on a session to see its folder, size, ID, activity, recent request, last reply, and resume command.

Session actions

Browsing never changes a session. Press a to review an action before it runs.

Codex archive and restore use Codex itself. Codex delete is permanent. Claude sessions can move to the system Trash. OpenCode delete is permanent and includes the selected session's descendants. Tree actions include folded descendants. Active Claude sessions are refused.

OpenCode and Hermes store sessions together in SQLite. Their ~ sizes rank logical session content; deleting one may not immediately shrink the database file. Kimi can export a verified session ZIP to the current directory; it does not provide a CLI storage action. Antigravity, Gemini CLI, Hermes, and OMP have no storage actions. Antigravity sizes include each conversation database and its matching brain/ artifacts once. Native child agents appear as trees.

Successful actions append a content-free record to $XDG_STATE_HOME/asdu/actions.jsonl, normally ~/.local/state/asdu/actions.jsonl.

Contributing

Bug reports, UI improvements, and new session sources are welcome. Keep changes small and use fictional session data in tests.

uv run pytest
uv run ruff check .

New sources start read-only. Add file-changing actions only when their lifecycle is understood and tested.
