Loop Engineering Sources

This site uses official documentation as the highest-trust source for tool behavior. Open-source projects and community articles are used for examples, patterns, and experimental exports. Pricing presets are examples only and should be verified against current provider pricing.

AGENTS.md and SKILL.md generators are based on official provider documentation and generalized into vendor-neutral templates. Tool directory entries include official docs, open-source projects, and community resources. Experimental tools are labeled clearly.
