FAQ
What is whathappened and what does it produce?
whathappened is a Grok Build Agent Skill that turns the X firehose around a topic into a short neutral briefing: what happened, where the conversation is, an opinion map, live debates, and receipts (real post links).
How do I install whathappened for use in Grok Build?
Install globally with `npx skills add kunchenguid/whathappened -g` (recommended) or locally with `npx skills add kunchenguid/whathappened`. You can also clone the repo and copy or symlink the skill folder into `~/.grok/skills/whathappened`.
Can I use whathappened outside of Grok Build?
No. The skill depends on Grok Build’s native X tools (`x_keyword_search`, `x_semantic_search`, `x_thread_fetch`, `x_user_search`). If those tools are missing, the skill should refuse rather than fake an X briefing from web search. Installing into other agents like Claude Code, Cursor, or Codex will not give a working run.
What kind of output does the skill generate?
The skill produces a markdown briefing with sections: Window, X sample, Entity resolve, What happened, Where the conversation is, Public opinion map, The live debates, Notable posts (receipts), and Gaps/caveats. It includes rough opinion‑camp shares, steelman vs critique points, and links to real X posts.
Are there any limitations or caveats I should be aware of?
Yes. The briefing can suffer from day‑0 recency bias, relies on an X/Twitter‑skewed sample, and may miss non‑English conversation. Weights or product details that are forthcoming (e.g., open weights promised for a future date) are treated as forward‑looking. The skill uses at most one web lookup solely to resolve the entity’s identity; all sentiment and discussion analysis stays X‑only.
How does the skill decide the time window for its analysis?
It uses an adaptive window: breaking stories are analyzed over minutes or hours, quieter topics widen only as needed to explain the story. The pipeline first measures velocity via a pulse (Latest) search, then commits to the shortest window that still captures the story—mode options are Breaking (hours), Same‑day, Story (days), or Background (longer only if needed).
