name: stock-brief description: Produce a situational brief on a single stock/ticker — its recent high-relevance news, insider activity, and what to watch next — using the AlphaAI MCP. Use when the user asks to "brief me on ", "what's going on with ", "catch me up on NVDA", or wants a quick read on one name.

Stock brief

Give a tight, decision-useful read on one ticker from AlphaAI's enriched feed. Not a price quote — a news brief: what's been happening, who's buying or selling, and what to keep an eye on.

Steps

1. Resolve the ticker. If the user gave a company name, not a symbol, call alphai_tickers(q=...) to find it. If alphai_ticker_news returns unknown_ticker=true, tell the user and stop — don't invent coverage.
2. Pull the ticker feed. Call alphai_ticker_news(ticker, collapse_stories=true). collapse_stories folds syndicated reprints into one row each and adds a sources_count corroboration signal — prefer it for a clean brief. Insider news is included by default; keep it.
3. Optional context. If the user wants the wider tape, call alphai_trending(limit=5) and note any market-level story that touches this name or its sector.
4. Deep-dive on demand. If one story clearly drives the brief and the user wants detail, fetch it with alphai_article(uid) for the full enrichment (ticker analysis, key entities). The article body is not served — work from the enrichment and summary.

Output

Keep it to a screen. Structure:

• One-line read — the single most important thing about this name right now.
• Top stories — 3–5 bullets, each: headline · relevance score · one-clause "why it matters". Lead with the highest relevance_score.
• Insider activity — any Form 4 / 13F rows from the feed: who, buy or sell, size if given. "No notable insider activity in the window" is a valid line.
• Watch next — 1–2 concrete things that would change the picture.

Guardrails

• Every story carries a 1–10 relevance_score; lead with the high ones and say the score so the user can calibrate.
• This is news, not advice. Don't issue buy/sell calls or price targets — summarize what the reporting says and let the user decide.
• If the feed is thin, say so plainly rather than padding. A short honest brief beats a long speculative one.
