What changed
Hacker News became a live source, and the per-platform agent tools were replaced by a single platform-dispatched social_* set.
Why it matters
For agent users this is the difference between learning a tool per platform and learning one. Adding a platform later doesn't change the tools your agent already knows.
How to use it
Agents call social_search, social_list_posts and friends with a platform argument. See the MCP docs for the full tool list.
