anti-reversing-techniques is a skill for Claude Code from Ghosteken/agent-harness. It costs 31 tokens per session (467 once invoked), scanned A, a copy of anti-reversing-techniques, MIT.

A security-analysis guide for examining software protections such as anti-debugging and obfuscation. It is intended for authorized penetration tests, malware analysis, capture-the-flag exercises, and security research.

In plain words
What is it for?
Use it to analyze protected binaries, investigate malware, study defensive techniques, or work on approved security exercises.
Why use it?
It sets clear authorization and scope checks before using techniques that could otherwise be unlawful or misused.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

anti-reversing-techniques scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AUTHORIZED USE ONLY: This skill contains dual-use security techniques. Before proceeding with any bypass or analysis:

  1. Verify authorization: Confirm you have explicit written permission from the software owner, or are operating within a legitimate security context (CTF, authorized pentest, malware analysis, security research)
  2. Document scope: Ensure your activities fall within the defined scope of your authorization
  3. Legal compliance: Understand that unauthorized bypassing of software protection may violate laws (CFAA, DMCA anti-circumvention, etc.)

Legitimate use cases: Malware analysis, authorized penetration testing, CTF competitions, academic security research, analyzing software you own/have rights to

Use this skill when

  • Analyzing protected binaries with explicit authorization
  • Conducting malware analysis or security research in scope
  • Participating in CTFs or approved training exercises
  • Understanding anti-debugging or obfuscation techniques for defense

Do not use this skill when

  • You lack written authorization or a defined scope
  • The goal is to bypass protections for piracy or misuse
  • Legal or policy restrictions prohibit analysis

Instructions

  1. Confirm written authorization, scope, and legal constraints.
  2. Identify protection mechanisms and choose safe analysis methods.
  3. Document findings and avoid modifying artifacts unnecessarily.
  4. Provide defensive recommendations and mitigation guidance.

Safety

  • Do not share bypass steps outside the authorized context.
  • Preserve evidence and maintain chain-of-custody for malware cases.

Refer to resources/implementation-playbook.md for detailed techniques and examples.

Resources

  • resources/implementation-playbook.md for detailed techniques and examples.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
