Tool Skills

Reusable agent skills for structured file workflows:

• JSON operations with jq
• YAML operations with yq (v4 syntax)
• Markdown structure/prose cleanup with mdq query workflows

This repository is meant for both humans and coding agents. Human onboarding lives here; agent execution policy and CI commands live in AGENTS.md.
