SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This guide helps identify and assess known Claude Code cache bugs and risks (e.g., sentinel replacements, --resume/--continue usage, attribution header exposure) that can affect session integrity and billing.

Core Features & Use Cases

  • Phase-based auditing of Claude Code configurations and binaries to surface cache and cost exposure.
  • Guidance on mitigations, updates, and best practices to reduce risk during development and deployment.
  • Reference for CC#40524 bugs (Sentinel, resume/continue handling, attribution header) and how to verify protections in your environment.

Quick Start

Run this audit at the start of a session to identify cache exposure risks and actionable mitigations.

FAQPage Schema
How do I audit Claude Code cache exposure risks in my local development setup?

Audit Claude Code cache exposure by checking configurations, CLI workflows, and binaries for sentinel content, resume/continue usage, and attribution header risks. Run an audit at the start of a session to detect vulnerabilities and apply recommended mitigations.

What are known Claude Code cache bugs related to sentinel strings and resume flags?

Known Claude Code cache bugs involve sentinel replacements, --resume/--continue usage, and attribution header exposure. These issues can affect session integrity and billing, requiring phase-based auditing of your binaries and tools to verify protections.

How can I check if my Claude Code configuration has attribution header exposure?

Check attribution header exposure by auditing your Claude Code settings and binary distributions for specific header configurations. The audit identifies exposure risks and provides guidance on mitigations, updates, and best practices to secure your environment.

Does this cache bug audit apply to CLI workflows and binary distributions?

Yes, the cache bug audit applies to local development setups, CLI workflows, hooks, settings, and binary distributions. It detects sentinel content, resume/continue usage, and attribution header risks across these environments to ensure comprehensive coverage.

Why should I run a Claude Code cache audit at the start of a session?

Running a cache audit at the start of a session identifies exposure risks early, preventing session integrity and billing issues. It checks version compatibility, cch sentinel strings, and resume/continue handling to recommend actionable mitigations and updates.

What limitations exist when mitigating Claude Code cache bugs in existing sessions?

Limitations include potential session integrity compromise and billing exposure if cache bugs are not addressed before starting. The audit detects these risks but mitigating them requires applying recommended updates and best practices to your configurations and binaries.
