Herdr Agent Sidebar

See what each agent is doing, grouped by workspace and tab.

Turn Herdr's Agents list into a compact task tree, with
readable labels, provider icons, optional animated loaders, and automatic
dimming of inactive spaces and their agents. This customizes the built-in
sidebar; it does not add a file explorer or another pane. No Herdr fork or build.

Real settings and loader demo in Herdr 0.8.2 / Ghostty 1.3.1 on Linux.
Titles and states are demonstration data; the plugin and rendering are real.
Capture details.

• Find the right agent. One-tab workspaces stay compact; multiple tabs get a
  tree. Working groups can move to the top without separating their agents.
• Read the task. Uses native conversation titles and local fallbacks—not
  another model call.
• Recognize Antigravity (AGY). Its own icon and blue agent text replace the
  generic diamond. Inactive rows still dim; blocked and done retain status colors.
• Animated loaders show who's working. Choose Dots, Orbit, or Pulse in
  Settings. Animation is off by default; turn it off again to restore static
  status marks and stop animation redraws.
• Inactive spaces and agents fade into the background. After a workspace
  has no working agents for ten minutes, its name in Spaces and its heading
  and agent rows in Agents dim together. They brighten as soon as any agent
  in that workspace starts working. Change the delay in Settings. This is visual
  dimming—not hibernation or stopping agents.

Before and after

Before — standard agent rows	After — this preset

Same four demo agents, same session, theme, and sidebar width.

Install

Requires Herdr 0.8.2+, Python 3.11+, and Git. Icon setup targets Ghostty
on Linux or macOS. Linux/Ghostty is live-tested; macOS is not yet live-tested.

Run inside a Herdr terminal pane:

git clone https://github.com/testy-cool/herdr-sidebar-config.git
cd herdr-sidebar-config
python3 setup_sidebar.py install
python3 setup_sidebar.py doctor

Open a fresh Ghostty process to load the installed icon font, then attach to
your still-running Herdr session. A new tab alone may retain the old font cache.

Another terminal, or no font changes? Use python3 setup_sidebar.py install --text
instead. Providers use short text labels; no Ghostty restart is needed for a font.
To inspect changes first, add --dry-run to the install command.

Setup backs up the files it changes and preserves unrelated Herdr settings.
It replaces the agent-row layout and sets workspace sorting. Keep this checkout:
Herdr links it as the plugin. Custom paths and manual setup →

Make it yours

Press prefix+, or choose Sidebar settings in the command palette.
Setup adds the shortcut only when it is free. Use arrows to select and change;
Enter saves, Esc cancels. Preferences survive updates and removal.

Animation adds redraws at up to eight frames per second. Turning it off restores
the static indicator and stops animation wakeups.
How it works and performance caveats →

Shorter branches, same hierarchy

Open prefix+,, choose Branch length, then press Enter to apply.
Short saves one column; Standard restores it. Real interaction in an isolated demo session.

What stays the same

Agent status, clicks, and keyboard navigation remain Herdr's own. The tree is
visual grouping, not collapsible folders; long labels still clip to the
sidebar width. Titles describe a task, not a generated live summary of every action.

The plugin reads local session metadata and bounded history to find labels. It
does not send prompts, run models, or change agent conversations. No API key,
telemetry, or background network service. Animation is optional; normal label
refreshes are event-driven. How labels and icons work →

Update or remove

Update from this checkout, then reapply the setup:

git pull --ff-only
python3 setup_sidebar.py install
python3 setup_sidebar.py doctor

To remove it and restore the backed-up layout:

python3 setup_sidebar.py uninstall --dry-run
python3 setup_sidebar.py uninstall

Removal keeps your checkout and preferences. Setup refuses to overwrite managed
files edited since installation. Keeping custom edits and troubleshooting →
