What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alphagbm-unusual-activity scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AlphaGBM Unusual Options Activity

Detects unusual options activity and classifies smart money signals to help you follow institutional positioning.

What This Skill Does

Concept Description
Volume/OI Ratio When today's volume far exceeds open interest, it signals new positioning
Block Trade A single large transaction (typically 100+ contracts) executed at one price
Sweep Order Aggressive order that sweeps across multiple exchanges to get filled fast — indicates urgency
Premium Flow Net dollar amount of call vs put premium — shows directional conviction
Sentiment Classification Categorizes activity as bullish sweep, bearish block, hedging, or earnings positioning
Historical Accuracy How often past unusual activity correctly predicted direction

How to Use

Input: A ticker symbol or market-wide scan request.

Output:

  • Unusual activity list: timestamp, strike, expiry, type (call/put), volume, OI, premium, trade classification
  • Sentiment classification per trade (bullish sweep, bearish block, hedging, earnings positioning)
  • Net premium flow (calls vs puts in dollar terms)
  • Historical accuracy: how often similar signals preceded the expected move
  • Aggregated smart money score

Example Queries:

  • unusual options activity — Market-wide scan of today's most unusual trades
  • smart money AAPL — Institutional flow signals for Apple
  • large trades NVDA — Block and sweep orders for NVIDIA
  • who's buying TSLA puts — Bearish flow analysis for Tesla
  • options flow SPY — Net premium flow for S&P 500 ETF
