Why is my OpenClaw agent showing internal thinking?

A bug in 2026.4.9 leaks the agent's internal reasoning/planning text into user-visible responses, especially when triggered by MMX-CLI interaction.

How to stop OpenClaw from exposing reasoning to users?

Downgrade from 2026.4.9 to 2026.3.31. The bug was introduced in the 4.9 update and relates to thinking content filtering.

Is the OpenClaw thinking leak a security risk?

Yes. Internal reasoning can reveal system prompts, decision logic, and operational details not intended for end users, potentially exposing sensitive information.

Which models are affected by the OpenClaw reasoning leak?

The bug appears model-independent — it affects the gateway's response filtering layer, not the model itself. All models show the issue on 2026.4.9.

What does leaked OpenClaw thinking look like?

Users see text like 'Mike wants to test if Claude Opus has English thinking process. Let me send a test response.' — internal monologue meant to be hidden.

OpenClaw 2026.4.9 exposes agent internal thinking to users — reasoning leak bug

Product Idea from this Signal

A CLI scanner that audits an OpenClaw deployment against government advisory requirements and the 138+ known CVEs, then outputs a compliance report

Belgium's CCB issued emergency advisories demanding highest-priority patching. Microsoft's security blog declared OpenClaw 'not appropriate for standard workstations.' The Dutch DPA warned against deploying on systems with sensitive data. 135,000+ instances are internet-exposed, 63% without authentication. But no tool specifically scans an OpenClaw installation against these recommendations. The generic governance toolkits (Microsoft Agent Governance Toolkit, Credo AI) cover broad AI agent risks but miss OpenClaw-specific CVEs, exposed gateway ports, plaintext credential storage, and ClawHub skill integrity. This product runs a single command against a live OpenClaw instance and outputs a pass/fail compliance report aligned with CCB, Microsoft, and Dutch DPA recommendations.
