What's Wrong?

Claude Code hangs indefinitely when running workflows or slash commands that read multiple files. The loading animation continues forever (tested up to 8+ minutes) with no response or error output. Simple prompts work fine. For example, "Hey, what's 2+2?" responds in 2 seconds. But any operation that loads multiple files as context (such as custom slash commands/workflows) hangs at the loading state (e.g. "Photosynthesizing...", "Flowing...", "Boondoggling..."). This started immediately after the auto-update to v2.0.60 on Dec 6. The same workflows worked perfectly before the update.

What Should Happen?

Workflows and slash commands should execute normally as they did in previous versions. File reading operations should complete and Claude should respond within seconds, not hang indefinitely.

Error Messages/Logs

No error messages are displayed. The terminal simply shows the loading animation indefinitely:
✶ Flowing… (esc to interrupt · 5m 28s · ↓ 276 tokens)
No errors appear in ~/.claude/debug/ logs.

Steps to Reproduce

Have a project with custom slash commands/workflows that read multiple config files (e.g. YAML, MD, XML files) Run claude or claude --dangerously-skip-permissions Execute a slash command that triggers multiple file reads Observe the loading animation continuing indefinitely with no response

To verify it's not a network/API issue:

Run claude and type a simple prompt like "Hey, what's 2+2?" - this works fine Run ping api.anthropic.com - network is fine (~5ms latency) Check status.claude.com - all systems operational

Additional Information

The --debug flag does not resolve the issue The --dangerously-skip-permissions flag does not affect the behaviour Multiple concurrent terminals all exhibit the same hanging behaviour The issue appears related to operations that load multiple files as context before sending to the API This may be related to #13188 which also identifies 2.0.60 as problematic
