name: insider-radar description: Scan SEC Form 4 insider trades and 13F ownership moves for a ticker or a watchlist using the AlphaAI MCP. Use when the user asks about "insider buying", "insider selling", "Form 4 activity", "who's buying ", "institutional ownership changes", or wants an insider-activity sweep.

Insider radar

Surface ownership-change signal: SEC Form 4 trades (officers, directors, 10% owners trading their own stock) and 13F moves (funds and foundations adjusting stakes). AlphaAI templates each filing into a relevance-scored news row, so the read-across is already done.

Steps

1. Single ticker. Call alphai_insider_news(ticker="<SYM>"). If the user wants only the strongest signal, raise the floor with min_relevance=8.
2. Watchlist. Call alphai_insider_news(ticker=...) once per name. If the user gave none, call alphai_insider_news() unfiltered for the broad tape.
3. Time-box on request. For "this week" / "since earnings", pass from_date (ISO, UTC). Paginate with cursor only if they ask for more.
4. Distinguish buys from sells. Open-market purchases by insiders are the higher-signal event; routine 10b5-1 scheduled sales and option-exercise sales are noise more often than not. Call that out — don't treat every sale as bearish.

Output

• Notable buys — insider purchases first: ticker · who/role · size if given · relevance. These are what most users actually want.
• Notable sells — flag whether each looks like a discretionary sale vs a scheduled/10b5-1 or option-related sale, where the feed says.
• Institutional (13F) — any fund stake increases/trims worth a mention.
• Read — one line: is the cluster leaning accumulation or distribution, or is it just routine?

Guardrails

• An insider sale is not automatically bearish (taxes, diversification, scheduled plans). Say what the filing shows; don't over-read it.
• One filing can span several tranches sharing a row — report the event, not a count of line items.
• Lead with relevance_score; "no notable insider activity in the window" is a valid, useful answer.
• News, not advice.
