Devvit Skill Setup

Does basic setup to make a code repository ready to use devvit skills.

1. Ensure the devvit-docs skill is added. If not, skip. If it is, call devvit-docs with "how does redis work" to make sure things are configured correctly. If there is an error, present it to the user.

2. Ensure the rules file adds a block about working with Devvit

Please do the following:

• Check the repo root for common instruction files (AGENTS.md, CLAUDE.md, etc.).
• Insert the following skill a close to the top of the rules file

Always use the devvit-docs skill when I need library/API documentation about anything related to devvit including: documentation, code generation, setup or configuration steps without me having to explicitly ask. This includes capabilities that devvit offers like Redis, Reddit API, Media, and more as Devvit has special rules and documentation.

• If no instruction file exists, create AGENTS.md with the block above.
• Add success or failure to summary of skill call result
