The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill recommends the installation of several standard cryptographic libraries and well-known security tools. These include Python packages like pycryptodome and z3-solver from official registries, and external tools such as SageMath, Hashcat, and RsaCtfTool from their respective official repositories.
[COMMAND_EXECUTION]: Provides various bash commands for environment configuration and for running cryptanalysis scripts. These commands are routine for the skill's documented purpose of performing cryptographic research and CTF challenge solving.
[DATA_EXPOSURE]: The skill processes untrusted external data (such as ciphertexts and public keys) that may be obtained from CTF challenges. While this is the intended use case, it represents a surface for indirect prompt injection if the challenge data contains adversarial instructions.
Ingestion points: Challenge data, keys, and ciphertexts are ingested from local files or via the WebFetch tool.
Boundary markers: None; the skill does not include specific delimiters or instructions to ignore embedded commands in the data being analyzed.
Capability inventory: The skill has access to Bash, Write, Edit, and WebFetch, which are used to implement the cryptographic solvers and interact with challenge servers.
Sanitization: No specific sanitization or filtering is applied to the input data before it is processed by the provided scripts.
