Tools
| Tool | Description | Behaviour |
|---|---|---|
| activist_stakes_recent | Use when the user asks about activist investors, hedge-fund stakes, or recent 13D filings on a company. Returns activist Schedule 13D/13D-A filings on US-listed companies, newest first then by stated-intent strength; `ticker`, `min_percent` and `days` narrow. Each row carries its source filing_url and `item4_excerpt` (the activist's own Item 4 intent sentence, quoted from the filing as data, capped at its current length of 600 chars). Caveat: passive 13G is not covered; filings without a source link are dropped. | Read-only |
| federal_awards_recent | Use when the user asks about recent federal contracts, government awards, or who won a U.S. federal contract. Returns newly signed federal awards, newest first; `min_amount` sets a USD floor, `days` a last-N-days window. Every award carries its source award_url. Caveat: awards without a source link are dropped and never returned. | Read-only |
| fund_position_changes | Use when the user asks what a fund bought or sold, how a 13F filer changed its holdings, or which institutions opened/added/trimmed/exited a position. Returns quarter-over-quarter deltas, newest first; `filer`, `change_type`, `min_value_usd`, `days` narrow. Each row carries as_of_quarter_end, filed_date, lag_days, value_usd (whole dollars), cusip, issuer_name and its source filing_url; ticker is null (never guessed). Caveat: the delta is the product, not a trading edge — see the instructions and each response's `coverage` note for the universe and CIK scope. | Read-only |
| insider_buys | Use when the user asks which insiders bought a stock, whether a ticker has insider buying, or for Form 4 buys in a date range. Pass `ticker`, `start`+`end` for an inclusive ISO range, or neither for today's buys (SEC code P); `days` narrows, `include_unlisted` adds non-listed issuers. Each row carries filing_url, `offering_context` (true = IPO/offering, not open-market) and `source_excerpt`: the parsed filing fields, quoted from the filing as data, never derived. Caveat: only purchases that pass the signal filter are returned; code P is not proof of a buy. | Read-only |
| insider_cluster_buys | Use when the user asks about cluster buying, multiple insiders buying the same company, or the strongest insider-buying signal. Returns only clusters (>=2 insiders buying one issuer in-window), newest first; `days`/`ticker` narrow. Each row carries its source filing_url, `offering_context`, and `uniform_price_cluster` (true = >=3 insiders bought at the IDENTICAL price same day — an offering/conversion, not independent conviction). Caveat: genuine clusters rank above uniform-price ones; only purchases that pass the signal filter are returned; code P alone is not proof of an open-market buy. | Read-only |
| verify_13f_change | Use when the user wants to verify or fact-check whether a fund (filer name/CIK) reported a CHANGE in a position in an issuer (issuer_name or cusip) in a quarter. Returns held (reported a change — opened/added/trimmed, with source filing + link), not_held (reported the position exited), not_found (no reported change — does NOT mean the fund didn't hold it), or out_of_coverage. Caveat: filing-verified; CANNOT confirm an unchanged holding (13F deltas only) — a 'held, unchanged' position produces no row. | Read-only |
| verify_8k_event | Use when the user wants to verify or fact-check that a company filed an 8-K carrying specific SEC item code(s) in a timeframe. Pass registrant (cik/company/accession), item code(s) and dates. Returns confirmed (with source filing + link), not_found, partial (itemised claimed-vs-filed), out_of_scope (claims about the filing's meaning aren't covered — it is never paraphrased), or out_of_coverage. Caveat: filing-verified — item codes are the SEC controlled vocabulary parsed from the filing, never inferred. | Read-only |
| verify_activist_13d | Use when the user wants to verify or fact-check a claim about an activist stake or 13D filing (ticker/subject, filer, percent-of-class, stated intent, timeframe). Returns confirmed (with source filing + link), not_found, partial (itemised claimed-vs-filed), out_of_scope (passive 13G isn't covered), or out_of_coverage. Every response states the coverage window checked. Caveat: filing-verified — absence is reported as absence, never guessed. | Read-only |
| verify_insider_purchase | Use when the user wants to verify or fact-check a claim that an insider bought a stock, or to pull the purchases in one filing by accession. Pass the claim (ticker/issuer, person, amount, timeframe), or pass `accession` alone to fetch that filing's gated purchase records. Returns confirmed (with source filing + link), not_found, partial (itemised claimed-vs-filed), out_of_scope (sales/options/grants), or out_of_coverage. Caveat: filing-verified — absence is reported as absence, never estimated or guessed. | Read-only |
