[Bug] Explore subagent hangs indefinitely on git operations with special characters in paths

Bug Description
Explore subagent hangs >10min on git operations. Repro: 1. Open Claude Code in a git repository (worktree increases reliability) 2. Spawn Explore subagent with a prompt that requests git show / git diff / git ls-tree, especially on paths with parens like src/app/(funnel)/ 3. Subagent hangs indefinitely (30+ min observed across multiple sessions) Expected: subagent returns within seconds (Bash inline runs same commands in <1s). Actual: subagent never returns, no timeout, no error. What I tested: - Explore with simple prompts (echo hello) works fine (~10s) - Issue reproduces on fresh sessions, not just long ones - Reproduces after machine restart - Anthropic API status: operational during repro - Claude Code: 2.1.121 (latest) - MCPs: cleaned (no zombies, no broken stdio) - Plugins: playwright + context7 disabled to rule out Workaround: run git operations via main Bash tool, never delegate to Explore. This blocked productive work for ~1h before isolating. Severity: high — Explore is the recommended tool for codebase exploration per agent description.
