Show HN: Algo-Trading-Skills - 501 agent skills for trading infrastructure

The repository provides 501 structured “skills” covering 16 engineering domains and major regulatory frameworks (SEC Rule 15c3-5, MiFID II, FCA, etc.) for building algorithmic trading infrastructure, each with unit-tested reference implementations and explicit “when not to use” guidance. The skills follow the agentskills.io standard, can be accessed via Claude Code, GitHub Copilot, Codex CLI, or other SKILL.md-compatible tools, and are intended solely for engineering guidance, not financial or compliance advice.
