SUMMARY

What it does

This Agent Skill instructs the agent to ground every framework-specific implementation decision in official documentation. The process is: detect the stack and versions from dependency files, fetch the relevant official documentation page, implement following the documented patterns, and cite sources with full URLs. It includes a source hierarchy (official docs > official blog/changelog > web standards > compatibility data), explicitly excludes non-authoritative sources (Stack Overflow, blog posts, training data), and mandates surfacing conflicts between docs and existing code. It also contains retrieval-safety guidance treating fetched documentation as untrusted data, with instructions to ignore injected directives and never hardcode outbound endpoints from fetched content without user consent. The skill is distributed as a SKILL.md file (9949 bytes, SHA-256 719d4e54083c90ded62112fb41df3dbc4619309118ee0e6aa4d846f92d8204af) under the MIT license in the addyosmani/agent-skills repository. No runtime authentication or pricing is declared; the skill is a set of instructions, not an executable service.
