# subagentbriefs.com — the Brief primitive

> A durable, D1-backed catalog of real "brief" conventions across disciplines that use the term as jargon: legal case briefs (IRAC), marketing/advertising creative briefs, and Anthropic's own prompt-engineering guidance for briefing Claude on a task. Every row cites a real URL or repo-relative file path.

## API
