Security Policy

Scope

This project documents Claude.ai's internal tools through reverse-engineering. While the book itself is documentation (not executable code), the subject matter touches on AI system internals, and discoveries may occasionally surface behaviors with security implications.

Reporting a Vulnerability

If you discover a tool behavior that could be exploited to:

  • Bypass Claude's safety guardrails
  • Access other users' data through shared storage or memory tools
  • Exfiltrate sensitive information via tool parameters or responses
  • Manipulate tool behavior through prompt injection in tool inputs
  • Escalate permissions beyond intended scope
  • Abuse the artifact execution layer (anthropic_api_in_artifacts, persistent_storage, MCP endpoints) for unintended access

Please report it responsibly:

  1. Do NOT open a public Issue. Security-relevant findings should not be disclosed publicly before they can be addressed.
  2. Email: Contact the maintainer directly at the email listed on the author's GitHub profile.
  3. Include:
    • Description of the behavior
    • Steps to reproduce
    • Platform(s) affected
    • Potential impact assessment
  4. Also consider reporting to Anthropic directly via their responsible disclosure process — they are best positioned to fix tool-level vulnerabilities.

What This Project Will Do

  • Acknowledge receipt within 48 hours
  • Assess whether the finding should be withheld from publication until Anthropic addresses it
  • Coordinate with Anthropic if appropriate
  • Credit the reporter (unless anonymity is requested) when the finding is eventually published

What This Project Will NOT Do

  • Publish exploit details before Anthropic has had reasonable time to respond
  • Document tools or behaviors specifically designed to facilitate harm
  • Provide instructions for bypassing safety systems
