Agent creation hangs on "initializing" before any model request is sent

Summary

Claude Code 2.1.114 gets stuck on agent creation in a local session. The UI stays on \"initializing\" / \"creating agent\", and no model request is sent at all.

This appears to fail before subagent model dispatch. Restarting Claude Code did not fix it.

Environment

• Claude Code: 2.1.114
• OS: Linux

Observed behavior

• Agent creation hangs on \"initializing\".
• A retry also failed with no work done.
• After restarting Claude Code, the issue persisted.
• No downstream model traffic is emitted when Agent tool is invoked.

Expected behavior

Claude Code should either:

• create the agent successfully, or
• fail fast with a surfaced error instead of hanging indefinitely on initialization.

Notes

Based on local investigation, this may be an internal agent lifecycle / pool-slot problem rather than a request-routing issue, but I do not have internal runtime logs to confirm that.
