Go over the actor's fields (non-transient) and, for each collection worth querying, consider how its data maps to a table in a database (an entity). You only declare one entity per table — the Expose mixin makes them queryable.
Extension Oql is a community-contributed Claude Code skill in the plugins-extensions sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/extension-oql/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever an app stores structured data (Maps/Lists/arrays of records) that should be answerable in natural language — "top customers", "revenue by region", "active projects". Adds a discoverable `schema()` and a JSON `execute()` query endpoint via the `caffeineai-oql` mops package's `Expose` mixin.
The Extension Oql Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
