Add deprecation/sunset checks to research agents before they recommend
external APIs, OAuth flows, or third-party services.
Changes:
- framework-docs-researcher: Added step 2 "Deprecation/Sunset Check"
and updated Quality Standards
- best-practices-researcher: Added Phase 1.5 "MANDATORY Deprecation Check"
This prevents wasted development time on deprecated APIs. For example,
Google Photos Library API scopes were deprecated in March 2025, and
without validation, developers can spend hours debugging OAuth errors
on dead APIs.
