Error Message

AddressSanitizer/LeakSanitizer-instrumented binary against a PoC inside a sandboxed container, Claude Code sometimes returns API Error: Claude Code is unable to respond to this request… appears to violate our Usage Policy… cyber content. The blocked content is just the tool's own crash trace (e.g. ==… ERROR: AddressSanitizer: heap-buffer-overflow …) from a legitimate reproduction run. There is no way to mark a session or working directory as "authorized security research" so these refusals don't fire.

Fix Action

Fix / Workaround

  • Stronger adherence to CLAUDE.md workflow instructions that require specific tools to be invoked before a deliverable is produced — e.g. a way to declare "tool X must be run and its output must be cited before a patch is written," enforced by the harness rather than relying on the model to
    self-police.

  • Optionally: a post-hoc explanation when a tool is skipped, so the user can see why the model decided it wasn't needed, instead of silently getting a code-only patch.

I'm running Claude Code as an autonomous agent inside a sandboxed Docker container to reproduce a published CVE, build the project with ASan, run a provided PoC, and propose a minimal patch. The
workflow is documented in CLAUDE.md and the environment is isolated. Two things happen:

Problem Statement

Claude Code currently has 1 gap that make it hard to use for authorized security research (CVE reproduction, red-teaming, academic vuln analysis):

AddressSanitizer/LeakSanitizer-instrumented binary against a PoC inside a sandboxed container, Claude Code sometimes returns API Error: Claude Code is unable to respond to this request… appears to violate our Usage Policy… cyber content. The blocked content is just the tool's own crash trace (e.g. ==… ERROR: AddressSanitizer: heap-buffer-overflow …) from a legitimate reproduction run. There is no way to mark a session or working directory as "authorized security research" so these refusals don't fire.

Proposed Solution

  • An authorized-security-research mode (CLI flag, setting, or per-project opt-in) that treats sanitizer output, crash traces, and PoC files as first-class technical content rather than cyber-policy
    triggers, when the user has affirmed authorization. Gated behind explicit consent, scoped to a working directory or container.

  • Stronger adherence to CLAUDE.md workflow instructions that require specific tools to be invoked before a deliverable is produced — e.g. a way to declare "tool X must be run and its output must be cited before a patch is written," enforced by the harness rather than relying on the model to
    self-police.

  • Optionally: a post-hoc explanation when a tool is skipped, so the user can see why the model decided it wasn't needed, instead of silently getting a code-only patch.

Alternative Solutions

  • Switching to an older Claude model (less refusal, but also weaker analysis).

Use Case Example

I'm running Claude Code as an autonomous agent inside a sandboxed Docker container to reproduce a published CVE, build the project with ASan, run a provided PoC, and propose a minimal patch. The
workflow is documented in CLAUDE.md and the environment is isolated. Two things happen:

  1. After the PoC runs and prints its sanitizer trace, the next model turn returns a cyber-content
    refusal instead of analysis.
  2. When the refusal doesn't fire, the model often skips cppcheck/valgrind/gdb entirely and writes a patch from reading the source, ignoring the explicit CLAUDE.md instruction that the patch must be
    derived from tool evidence.

Both behaviors make the workflow unreliable for legitimate security research.

extent analysis

TL;DR

Implement an "authorized security research" mode to exempt sanitizer output and crash traces from cyber content policy triggers.

Guidance

  • Consider adding a CLI flag or setting to enable authorized security research mode, which would treat sanitizer output and crash traces as technical content rather than cyber policy triggers.
  • Implement a mechanism to gate this mode behind explicit user consent, scoped to a working directory or container.
  • Review the CLAUDE.md workflow instructions to ensure that specific tools are invoked before a deliverable is produced, and consider enforcing this through the harness rather than relying on the model to self-police.
  • Investigate the possibility of providing a post-hoc explanation when a tool is skipped, to help users understand why the model decided it wasn't needed.

Example

No code snippet is provided as the issue does not contain sufficient technical details to generate a specific example.

Notes

The proposed solution requires careful consideration of the security implications of exempting certain content from cyber policy triggers. It is essential to ensure that this mode is properly gated and scoped to prevent potential misuse.

Recommendation

Apply a workaround by implementing an "authorized security research" mode, as this would address the primary issue of cyber content refusals during legitimate security research. This approach would require careful implementation and testing to ensure that it does not introduce security vulnerabilities.
