Claude Code: allow. ### `get_dataset_stats` - The name "get_dataset_stats" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Discover what data is available before querying: date ranges, contract counts, symbol counts and sector coverage for the unusual-activity dataset and its daily aggregates. Call this first when unsure about available history. ``` ### `get_expiry_concentration` - The name "get_expiry_concentration" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Where the day's unusual premium sits along the expiry axis, in DTE buckets (0-7, 8-30, 31-90, 90+) with call/put splits. Heavy short-dated premium reads as event bets; heavy long-dated as positioning. ``` ### `get_flow_history` - The name "get_flow_history" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text End-of-day series of one symbol's UNUSUAL options flow (aggregated from the contracts that passed the unusual filter - not the full tape): daily call/put volume, premium, C/P ratios, average IV, net delta and the consecutive-day streak. ~75 trading days - the series behind back-tests and 'how has unusual flow on NVDA developed?' ``` ### `get_flow_sentiment` - The name "get_flow_sentiment" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Bullish/bearish classification of each symbol's unusual flow with a 0-9 strength score, based on call/put volumes, premium and net delta. Pass a symbol for that ticker's sentiment time series (date_from, date_to, limit apply); omit it for the cross-market snapshot (filterable by sector, side, minimum strength or premium). ``` ### `get_flow_streaks` - The name "get_flow_streaks" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Symbols with unusual options activity on N+ consecutive trading days, with the dominant side (call/put). Persistent unusual flow is a stronger signal than a single print - use for 'where does money keep showing up?' ``` ### `get_iv_rank` - The name "get_iv_rank" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text IV rank and IV percentile per symbol against its rolling history (needs 20+ days). Pass a symbol for its IV-rank time series (lookback_days, limit apply); omit it for a ranked snapshot (e.g. side=put&min_rank=0.8 finds elevated put IV; side=both ranks by the higher of call/put IV rank). ``` ### `get_market_regime` - The name "get_market_regime" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Market-wide breadth of unusual flow per trading day: breadth score 0-100, aggregate call/put ratio, regime label (bullish/bearish/mixed) and signal counts. Use for 'what's the overall tone of the unusual-flow tape?' ``` ### `get_oi_changes` - The name "get_oi_changes" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Day-over-day open-interest change per symbol (total, calls, puts) - fresh positioning being built or unwound. Pass a symbol for its OI-change series (date_from, date_to, limit apply); omit it for market-wide gainers/losers. ``` ### `get_sector_flow` - The name "get_sector_flow" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Which sectors the day's unusual options premium is concentrating in: total premium, volume, average net delta and bullish/bearish symbol counts per sector label (11 GICS sectors plus Diversified, Unknown and Unclassified; only labels with activity, at most 14 rows). ``` ### `get_symbol_flow` - The name "get_symbol_flow" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Every unusual contract on a single ticker, ranked by score (Vol/OI weighted by premium). Use when the question is about one specific stock's unusual options flow. ``` ### `get_top_prints` - The name "get_top_prints" says "get": a word for reading. - Tag private-data: The description's first sentence says "email": it reads mail. - Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write. Description, as the server wrote it: ```untrusted-server-text The day's biggest options bets ranked by estimated premium - the same view OptionsBell alert emails lead with.
