perplexityai/api-platform-developers ? reverse-engineered prompt

Build me a small open source repo for Perplexity API Platform skills that works with Claude Code, Codex CLI, and other Agent Skills clients.

I want it to feel like a real skill marketplace repo, with clear install steps, a skill that helps migrate an app from Sonar chat completions to the Agent API, and docs support so the agent can look up the latest Perplexity API docs when needed. It should be easy to install as a plugin or by copying the skill into a project or user skills folder, and the README should explain both paths in plain English.

Please make the repo polished and ready to publish, with the skill content, plugin metadata, and any needed docs so someone can use it right away. If you need to check the latest Perplexity docs or client instructions online, go ahead and do that.
