工具（13）
🟢insider_signals(start, end, limit, offset, days, ...)
The single entry point for Rule-2 insider-buy signals (SEC Form 4 code P purchases). ONE tool covering three queries, chosen by which args you pass: give `start` AND `end` for an inclusive ISO date range; give `ticker` alone for one ticker (case-insensitive); give neither for today's signals. Optional `days` narrows to the last N days; `include_unlisted` adds non-exchange-listed issuers (default listed-only). Returns the newest 25 by default (set `limit`; page with `offset`); the response's `total_matched` reports the full count and `coverage` states the window of filings actually collected. Code P is not necessarily open-market: each record carries `offering_context` (true = an IPO/offering/private-placement allocation, NOT an open-market buy). Each record carries its source filing_url and a `source_excerpt`: the exact parsed filing field values quoted from the filing, treated as data (a fixed whitelist of fields, never prose, never derived). (This supersedes the separate insider_signals_today / _by_ticker / _by_date_range tools, which remain for now and return identical data.)

}🟢insider_signals_today(limit, offset, days, include_unlisted, ticker)
Rule-2 insider-buy signals filed today (SEC code P purchases). Code P is not necessarily open-market: each record carries `offering_context` (true = an IPO/offering/private-placement allocation, NOT an open-market buy). Returns the newest 25 by default (set `limit`; page with `offset`); the response's `total_matched` reports the full count. Optional `days`/`ticker` filters. Each record carries its source filing_url, and a `source_excerpt`: the exact parsed filing field values (issuer, insider, amounts) quoted from the filing, treated as data — a fixed whitelist of fields, never free prose, never derived.

All Rule-2 insider-buy signals for one ticker (case-insensitive). Returns the newest 25 by default (set `limit`; page with `offset`; optional `days`); `total_matched` reports the full count. Each record carries its source filing_url and a `source_excerpt`: the exact parsed filing field values quoted from the filing, treated as data (a fixed whitelist of fields, never prose, never derived).

Rule-2 insider-buy signals filed within an inclusive ISO date range.

}🟢insider_cluster_buys(limit, offset, days, include_unlisted, ticker)
Rule-2 cluster buys only (>=2 insiders buying the same issuer in-window) — the highest-signal subset. Each row carries `uniform_price_cluster`: true when >=3 distinct insiders bought at the IDENTICAL price on the same filed_date for the same issuer — the fingerprint of an offering/conversion (one administered price), NOT independent open-market conviction. Note Form-4 code P covers open-market purchases AND some offering/conversion purchases filed under P; the per-row `offering_context` flag (and `uniform_price_cluster`) mark the latter. Genuine clusters rank ABOVE uniform-price ones. Returns the newest 25 by default (set `limit`; page with `offset`; optional `days`/`ticker`); `total_matched` reports the full count. Each record carries its source filing_url and a `source_excerpt`: the exact parsed filing field values quoted from the filing, treated as data (a fixed whitelist of fields, never prose, never derived).

Recently signed U.S. federal new awards from USAspending.gov, newest first. Returns the newest 25 by default (set `limit`; page with `offset`); `total_matched` reports the full count. Optional min_amount (USD floor) and `days` (last-N-days window). Every award carries its source award_url; awards without a source link are dropped and never returned.

Recent activist Schedule 13D / 13D-A filings on US-listed companies, newest first then by stated-intent strength (control/take-private > board/proxy > strategic/value, or none stated). Returns the newest 25 by default (set `limit`; page with `offset`); `total_matched` reports the full count. Optional min_percent (percent-of-class floor), ticker, and `days` (last-N-days window). Every stake carries its source filing_url and an `item4_excerpt`: the activist's own Item 4 intent sentence quoted from the filing verbatim, treated as data and capped at its current length (220 chars); filings without a source link are dropped.

}🟢fund_position_changes(filer, change_type, min_value_usd, limit, offset, ...)
What large institutional filers CHANGED quarter-over-quarter in their SEC 13F-HR holdings (opened / added / trimmed / exited a position) — the delta is the product; the raw snapshot is only the input. Every row carries as_of_quarter_end, filed_date and lag_days (values are up to ~45 days stale), value_usd in whole dollars, cusip + issuer_name, and its source filing_url. ticker is null (no authoritative free CUSIP->ticker source; never guessed). A missing prior quarter is the explicit state 'first_filing_on_record', not 'everything new'. Covers LONG US 13(f)-listed positions only — no shorts, non-US, or options. UNIVERSE: the fifty largest 13F filers by reported value as of the latest quarter, re-ranked quarterly. Because it is ranked BY REPORTED VALUE, the head is the biggest asset managers (BlackRock, Vanguard, State Street, Fidelity, ...) whose quarter-over-quarter changes largely reflect index rebalancing, not conviction; the feed reports WHAT WAS FILED, not what it means, and does not tag any manager active or passive (that would be inference). Coverage is PER SEC CIK, not per brand: a firm filing under several CIKs appears as several entries, and when a filer's 13F moves to a new CIK, historical coverage stays attached to the CIK that filed it. This is a convenience/completeness view of public data, NOT a trading edge. Returns the newest 25 by default (set `limit`; page with `offset`); `total_matched` reports the full count. Optional filer, change_type, min_value_usd, and `days` (last-N-days window).

Returns status=confirmed with the source filing(s) + link; not_found; partial (same insider/company but value/date differs, itemised claimed-vs-filed); out_of_scope (sales/options/grants aren't covered); or out_of_coverage (outside the collected window).

Check a claim about an activist stake (ticker/subject, filer, percent-of-class, stated intent, timeframe) against the filed Schedule 13D/13D-A record. Returns status=confirmed with the source filing(s) + link; not_found; partial (same filer/subject but percent/intent/date differs, itemised claimed-vs-filed); out_of_scope (passive 13G isn't covered); or out_of_coverage (outside the collected window).

Check a claim that a registrant (cik/company/accession) filed an 8-K carrying specific SEC item code(s) in a timeframe, against the filed record. Returns status=confirmed with the source filing(s) + link; not_found; partial (same registrant/filing but the claimed item(s) aren't carried, or the date differs — itemised claimed-vs-filed); out_of_scope (claims about the body's meaning/materiality aren't covered — the filing is never paraphrased); or out_of_coverage.

}🟢verify_13f_change(filer, issuer_name, cusip, quarter, start, ...)
Answers whether a fund (filer name/CIK) REPORTED A CHANGE in a position in an issuer (issuer_name or cusip) in the covered quarter — it CANNOT confirm an unchanged holding. The 13F store is quarter-over-quarter deltas, so a 'held, unchanged' position produces no row and is indistinguishable here from 'never held'. Returns status=held when the fund reported a CHANGE (opened/added/trimmed) that quarter, with the source filing(s) + link; not_held (the fund reported the position EXITED that quarter — a filed 'no', distinct from not_found); not_found (no reported CHANGE to that position in the covered window — which does NOT mean the fund didn't hold it, only that it reported no change); or out_of_coverage (the claimed quarter is outside the collected as-of window). Every response states the coverage window checked. Rule-2: LONG US 13(f) positions only, values are as-of quarter-end and up to ~45 days stale, and ticker is never guessed — match on issuer_name or cusip.
