Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cryptanalysis-attack-techniques

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent reads the source code first to spot an exploitable structure, such as linearity, partial leaks or a weak generator, then writes a Python solver. It covers lattice attacks, padding oracles and recovery of secrets shared across non-prime moduli.
