/agents TUI dialog shows 'No agents found' while CLI discovers all agents

Reproduction

1. Create agents in .claude/agents/ (project-scoped) and ~/.claude/agents/ (user-scoped)
2. Run claude agents from terminal — correctly shows all agents
3. Inside Claude Code TUI, run /agents — shows "No agents found"

Expected

/agents should show the same agents that claude agents discovers.

Environment

• Claude Code v2.1.90
• Arch Linux 6.19.10-arch1-1
• Project-scoped agents in .claude/agents/ (5 agents)
• User-scoped agent in ~/.claude/agents/ (1 agent)

Workaround

Agents work when invoked via conversation context or claude --agent agent-name. Only the /agents interactive dialog fails
to render them.
