Skill Claude CodeCodex
Multi-agent workflow (tracer/resolver/bypass) for secure code review, exploitability triage, and PoC validation in codebases. Use when conducting structured security research or penetration test analysis.
Skill Claude CodeCodex
A product-building guide with two modes: it chooses the right skill before a task and suggests the next step after one is finished. It covers the stages of clarifying an idea, building the product, and getting it running.
Skill Claude CodeCodex
A skill for programming PECMD2012 scripts, which are used in lightweight Windows PE startup environments and system tools. It covers GUI tools, initialization scripts, disk partitioning, batch-file conversion, information collection, and debugging.
InternetMaximalism/lean-reinforced-concrete
Skill Claude CodeCodex
A follow-on skill for deeper security auditing once a system has been formalized in Lean (e.g. by lean-formal-audit and the audit/ folder exists). It turns the existing Lean formalization into an offensive tool: running Lean code (#eval / decide / #print axioms), using reasoning to form attack hypotheses, doubting and…
Skill Claude CodeCodex
An error-reflection and learning workflow activated with /aristotle after someone reports a mistake or incorrect result.
