Home Assistant Integration Knowledge

If you're building or maintaining Home Assistant integrations, this skill teaches Claude the project's conventions and file structure. It knows where integration code and tests live, enforces rules like not making polling intervals user-configurable, and steers you toward platinum and gold quality scale integrations as examples. The guidelines are opinionated in a good way, like preferring direct dictionary indexing over .get() so bad assumptions fail fast. It also covers platform-specific rules for diagnostics and repairs. Useful if you're contributing to the home-assistant/core repo or just want your custom integration to follow the same patterns the core team uses.
