  What this check looks for
Description, as the server wrote it
Use when the user wants to verify 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 `accession` alone for that filing's gated purchase records. Returns confirmed, not_found, partial, out_of_scope (sales/options/grants), or out_of_coverage. Each matched filing carries `transaction_date`, `acceptance_datetime`, `aff10b5One` (10b5-1 flag), `is_amendment`/`original_accession` (4/A linkage), and `partial_fields` (reason for any null). Caveat: filing-verified — absence is reported, not guessed.

Changes things 9Creates or changes something that can be changed back.Claude Code: ask

activist_stakes_recentUse when the user asks about activist investors, hedge-fund stakes, or recent 13D filings on a company.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.
Annotations the server declares
- title: Recent activist hedge-fund stakes (SEC Schedule 13D)
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
federal_awards_recentUse when the user asks about recent federal contracts, government awards, or who won a U.S.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.
Annotations the server declares
- title: Recent U.S. federal contract awards (USAspending.gov)
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
fund_position_changesUse 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.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.
Annotations the server declares
- title: Hedge-fund / institutional position changes (SEC 13F, quarter-over-quarter)
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true

insider_amendments_recentUse when the user asks which insider filings were amended, corrected, or restated, or wants recent Form 4/A amendments.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Use when the user asks which insider filings were amended, corrected, or restated, or wants recent Form 4/A amendments. Returns 4/A amendments, newest-filed first; `ticker`, `issuer_name`, `person`, `start`/`end`, `days` narrow. Each row carries the amendment_accession, filed_date, issuer/insider, source filing_url, the original_accession it amends (when collected), and `changed_fields` (before/after). Caveat: when the original is not collected the amendment is still listed with original_in_corpus=false and before/after null (never guessed); linkage is by issuer/owner/period.
Annotations the server declares
- title: Recent Form 4/A amendments and what each corrected (SEC Form 4/A)
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
insider_buysUse when the user asks which insiders bought a stock, whether a ticker has insider buying, or for Form 4 buys in a date range.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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`, `transaction_date`, `acceptance_datetime`, `aff10b5One` (10b5-1 flag), `is_amendment`/`original_accession` (4/A linkage), and `partial_fields` (reason for any null). Caveat: only purchases that pass the signal filter are returned; code P is not proof of a buy.

- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

Description, as the server wrote it
Use when the user asks about cluster buying or several insiders buying the same company. Returns only clusters, two or more insiders buying one issuer in the window, newest first; days and ticker narrow. Each row carries filing_url, offering_context, uniform_price_cluster (true when 3+ insiders bought at one price on one day), `transaction_date`, `acceptance_datetime`, `aff10b5One` (10b5-1 flag), `is_amendment`/`original_accession` (4/A linkage), and `partial_fields` (reason for any null). Caveat: only purchases that pass the signal filter are returned; code P alone is not proof of a buy.

- title: Insider cluster buys — multiple insiders buying the same stock (SEC Form 4)
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
verify_13f_changeUse 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.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.
Annotations the server declares
- title: Fact-check a 13F position-change claim against SEC Form 13F-HR
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
verify_8k_eventUse 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.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.
Annotations the server declares
- title: Fact-check an 8-K disclosure claim against SEC Form 8-K
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
verify_activist_13dUse 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).No findings

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.
Annotations the server declares
