Add agentify-openapi skill — generate AGENTS.md from OpenAPI specs 🤖🤖🤖

[koriyoshi2041]

Summary

Adds a new skill agentify-openapi that teaches GitHub Copilot how to use Agentify (agentify-cli on npm) to transform OpenAPI specifications into agent interface files.

What Agentify does:

• Takes any OpenAPI spec (Swagger 2.0 or OAS 3.x) as input
• Generates up to 9 agent interface formats: AGENTS.md, MCP Server, CLAUDE.md, .cursorrules, Skills, llms.txt, GEMINI.md, A2A Card, and CLI
• Automatically selects a tiered generation strategy based on API size (small/medium/large) to avoid context window overflow
• MIT licensed, TypeScript, available as npx agentify-cli transform <spec>

Why this skill is useful:

• Complements the existing create-agentsmd skill (which writes AGENTS.md manually) by offering automated generation from an OpenAPI spec
• Helps teams with existing REST APIs quickly generate standardized agent interface files
• Supports the AGENTS.md standard adopted by 60K+ repositories

Contribution checklist:

• Branch created from staged
• Skill validates (npm run skill:validate passes)
• README updated (npm start ran, docs/README.skills.md updated)
• Follows SKILL.md frontmatter format with name and description
• No paid services required — fully open-source (MIT)
