Claude Code Bash Tool Recursive Process Fork Bomb Consumes Entire Usage Quota

What this error means

[BUG] Running claude sessions list via Bash tool triggers recursive process fork bomb — spawns ~197 concurrent claude --dangerously-skip-permissions instances is a Claude Code failure pattern reported for developers trying to claude code user wrapping claude in shell function with —dangerously-skip-permissions accidentally triggers recursive process spawning (~197 instances), consuming entire monthly usage quota instantly. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue anthropics/claude-code#58838 (created 2026-05-13, 3 comments, open). Brand-new issue with extremely clear error signature and dramatic commercial impact (entire quota wiped in minutes). Distinct from #48915: #48915 is about gradual overconsumption; this is an immediate runaway process bug triggered by shell aliasing. Category: AI Coding Tools. No prior coverage. Very fresh topic = low ranking difficulty.

Quick fixes

1. Confirm the exact error signature matches [BUG] Running claude sessions list via Bash tool triggers recursive process fork bomb — spawns ~197 concurrent claude --dangerously-skip-permissions instances.
2. Check the Claude Code account, local tool state, and provider configuration involved in the failing workflow.
3. Reduce request pressure, check quota or plan limits, and retry with backoff instead of immediate repeated requests.

Platform/tool-specific checks

• Verify the command, editor, extension, or API client that produced the error.
• Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
• Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

1. Capture the exact error message and the command, editor action, or request that triggered it.
2. Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
3. Review the source evidence below and compare it with your environment.
4. Apply one change at a time and rerun the smallest failing action.
5. Keep the working fix documented for the team or deployment environment.

How to prevent it

• Keep provider/tool configuration documented.
• Record non-secret diagnostics such as tool version, provider name, model name, and command path.
• Add a lightweight check before CI or production workflows depend on the tool.
