Improve Agent Navigation: Tree View, Alphabetical Sorting, and Active/Inactive Filtering

Problem / Motivation

Managing many agents (10–20+) becomes cumbersome with the current agent selector UI:

• Agents are shown in a long, flat list
• The list is not alphabetical, making scanning difficult
• Agents with long descriptions consume significant vertical space
• There’s no clear way to:
  • group related agents
  • mirror filesystem organization
  • hide or close inactive / stopped agents
• Navigation via Tab / Shift+Tab becomes unwieldy at scale

This makes multi-agent workflows harder than necessary, especially for users running many specialized agents or namespaces.

Proposed Solution (Minimal Viable Improvements)

Alphabetical Sorting

• Sort agents alphabetically by name as a baseline
• This alone would significantly improve usability

---

Hierarchical / Tree-Based Agent View (Filesystem-Mirrored)

Allow agents to be grouped via a simple path or namespace convention, for example:

git/commit-agent
git/review-agent
infra/docker-agent
infra/k8s-agent
rag/ingest-agent
rag/retrieval-agent

Rendered as:

git/
 ├─ commit-agent
 └─ review-agent
infra/
 ├─ docker-agent
 └─ k8s-agent
rag/
 ├─ ingest-agent
 └─ retrieval-agent

This would:

• Mirror how users already organize agents on disk
• Reduce cognitive load
• Scale cleanly with many agents
• Avoid introducing new configuration formats

---

Active vs Inactive Agent Filtering

• Provide a way to hide or collapse inactive / stopped agents
• Examples:
  • Show only active agents
  • Archive inactive agents
  • Visually dim inactive agents

This avoids cycling through inactive agents just to find the few currently in use.

---

Optional Enhancements (Nice-to-Have)

• 2D navigation:
  • Left/right → namespace
  • Up/down → agents within namespace
• Collapsible descriptions (single-line vs expanded)
• Search / fuzzy filter for agent names
• Keyboard shortcuts to jump between namespaces

---

Why This Matters

As users adopt:

• multi-agent workflows
• delegated agent responsibilities
• longer-lived agent processes

…the current flat list does not scale well.

A tree-based, alphabetical, filterable agent selector would:

• dramatically improve usability
• align with existing filesystem mental models
• reduce friction for power users
• remain simple for users with only a few agents

Willingness to Contribute

Happy to help prototype or implement this if there’s alignment on direction (UI + data model).
