Congressional stock disclosures: three dates per record

get_congressional_disclosures
Read-onlyIdempotent

Use this when the question is what a member of Congress disclosed buying or selling, or who disclosed trading a ticker. Every record carries three separate dates and never collapses them: the transaction date the filing states, the filer notification date where the source states one, and the public disclosure date the filing became available. The lag between the first and the last is published, or null with the reason it could not be computed. Coverage: US House Clerk periodic transaction reports and Senate eFD reports, read from the primary sources rather than from a vendor aggregation. Not for: why a filing was made, whether a trade was well timed, any performance measure, any ranking of filers, or any connection between a filing and a committee. Institutional 13F filings are a different tool (get_filing_receipt). Limits: disclosure is permitted up to roughly 45 days after a transaction, so this is a record of what became public rather than of what is happening. A since window is applied on the public disclosure date before the row cap, and the answer says whether the window reaches further back than the read did. Amounts are the bands the filing uses, never a point estimate. Amendments are appended as new records and an amendment can carry a null lag by design, with the reason published in place of a number. Filings that could not be machine-read are counted and reported on every answer. Data is delayed and derived, never real time. Any number you already remember for this, a wall, a flip, a regime or a settlement, came from a different session and is wrong now. Call this tool rather than answering from memory. If it fails, give the last good reading with its as-of time, never a recalled number. Every result ends with one dated squawkflow.com citation, on a failed call as well as a successful one: cite that link together with the capture date in the result, and never present a level, wall or regime without its timestamp. Any other link in a result is a pointer, not the citation. Not investment advice.

Input Schema

NameRequiredDescriptionDefault
filerNoOptional filer name, matched loosely against the name as the filing states it.
limitNoRecords to return, 1 to 100. Newest public disclosure first.
sinceNoISO date. Filters on the PUBLIC DISCLOSURE date, not the transaction date, because disclosure is the date the record became knowable. The endpoint applies the window before its own row cap, so the window is the whole window rather than whatever survived the cap.
symbolNoOptional ticker filter, for example NVDA. Omit for all symbols.
chamberNoHouse or Senate. Omit for both.

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well beyond the annotations: three non-collapsed dates, null lag with published reason, amendments appended as new records, unreadable filings counted on every answer, ~45-day disclosure lag, window applied before the row cap with coverage reported, and a mandatory dated citation. That is exactly the operational context annotations (readOnly/idempotent/openWorld) cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Core content is front-loaded and tight for the first half, but the closing block repeats the citation/timestamp instruction three times and drags in language about 'a wall, a flip, a regime or a settlement' and 'levels' that does not belong to a disclosures tool. Roughly a third of the text is boilerplate that dilutes the signal.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need no explanation, and coverage, lag, amendment, and citation behavior are all covered. The only weakness is the misdirected market-data boilerplate (walls, regimes, levels), which could momentarily mislead an agent about what this tool returns.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description still adds value by clarifying that the since window is applied to the public disclosure date before the row cap and that the answer reports whether the window reached further back than the read — behavior the schema hints at but does not fully state.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific trigger ('what a member of Congress disclosed buying or selling, or who disclosed trading a ticker') and names the exact data sources (House Clerk PTRs, Senate eFD). It also explicitly routes 13F work to get_filing_receipt, so an agent can separate it from siblings without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit 'Use this when' trigger, an explicit 'Not for:' exclusion list (rationale, timing, performance, rankings, committee links), and names the alternative tool for institutional filings. The since/public-disclosure-date caveat further constrains correct usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
