Claude Code: ask. ### `screen_holdings_us` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Screen 13F holdings by period, ticker, value, and rating; returns each matched fund with only the position(s) that matched Results are wrapped in an envelope: `results` holds up to `limit` funds (max 500), `total_count` is the full server-side match count, and `truncated` says whether paging with `offset` would surface more. `period` accepts '2026-Q2' or an ISO date like '2026-06-30'. ``` ### `screen_insiders` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Screen insider activity by country, date, value, role, and ticker Screens one market per call, selected by `country`: 'KR' returns individual insider transactions, 'JP' returns 5%+ shareholding reports. The response echoes `country` — switch on it before reading `results`, since the two markets return different record shapes. There is no US coverage; use the 13F screen for US institutional flows. ``` ### `screen_investor_catalyst_record_us` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Screen funds by their track record on binary events (any sector) Ranks 13F filers by how their positions resolved through binary events — single-day moves >= ~25%, price-defined, NOT verified cause labels. In biotech these are trial readouts / FDA decisions / buyouts; elsewhere earnings blowups, guidance cuts, M&A. `sector='all'` (default) ranks across everything; `'biotech'` and lowercased sector names ('technology', 'energy', ...) scope the record. `hit_rate` = pops held / events decided; `impact_usd` is dollar-weighted (position value x event return). Always pass `min_events` (>= 5) — a perfect rate on 2 events is noise. Chain with `get_investor_holdings_us` to see what a proven event-caller is buying now, or `screen_investor_sector_exposure_us` to intersect with sector specialists. ``` ### `screen_investor_sector_exposure_us` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Screen investors by sector concentration (e.g. top biotech specialists) Ranks 13F filers by the share of their portfolio in one sector, computed from sector-tagged top-50 holdings. `tier` buckets: specialist (>=60%), heavy (30-60%), tilted (10-30%), minimal (<10%). Interpretation caveats: corporate venture arms (Gilead, Pfizer, GSK) and single-stock endowments (e.g. Lilly Endowment holds only LLY) rank as specialists — pass `min_positions` (e.g. 5) to screen for genuinely diversified sector pickers. Chain with `get_investor_holdings_us` / `get_investor_changes_us` to see what a specialist is buying now. ``` ## Only reads (28) Looks things up and changes nothing.
