anti-reversing-techniques

anti-reversing-techniques is a skill for Claude Code, Codex from pinkpixel-dev/skills-collection-1. It costs 31 tokens per session (407 once invoked), scanned A, a copy of anti-reversing-techniques, Apache-2.0.

A security research guide to analyzing anti-debugging and obfuscation techniques in protected software, for authorized testing or analysis.

In plain words
What is it for?
Use it in authorized penetration tests, malware analysis, CTFs, or research on software you own or are permitted to inspect.
Why use it?
It clarifies the permission and scope checks needed before examining software protections and helps keep that work within lawful boundaries.

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 9d 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.

What it actually says

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.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
