The Agent Skills Directory

[SAFE]: The skill is an extensive knowledge base for cryptographic research and competition. It documents well-known attack vectors and provides practical code snippets for educational purposes.
[EXTERNAL_DOWNLOADS]: The documentation references standard security tools and official repositories (e.g., RsaCtfTool, v8_rand_buster, hashpumpy). These are established resources in the cybersecurity community and are listed for reference and tooling purposes.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to process external cryptographic parameters, such as modulus values and ciphertexts. While this constitutes a data ingestion surface, the agent is directed to use mathematical libraries (like sympy, gmpy2, and z3-solver) to perform analysis. This is a standard and safe design for tools in this domain.
[COMMAND_EXECUTION]: The skill provides instructions for using command-line utilities like sage, hashpump, and seccomp-tools. These instructions are intended for the user or agent to perform legitimate security analysis and do not involve the execution of arbitrary or malicious shell commands.
