They are how you get grounded source material into a chain before an AI step reasons over it. *** ## Search Uploaded Documents Deterministic Medium Hybrid dense plus keyword search over a matter's uploaded documents. Returns the top relevant passages for downstream summary, drafting, or verification steps. **Config** | Field | Type | Required | Default | Notes | | ----------------- | ------------- | -------- | ------- | -------------------------------------------------------------------------------- | | Query | Text | Yes | | What to search for, up to 2,000 characters. | | Documents | Document list | No | | Narrow the search to specific documents. Leave blank to search the whole matter. | | Number of results | Integer | No | 10 | 1 to 50 passages. | **Outputs** | Field | Contents | | ----------- | ---------------------------------------------------- | | Chunks | The retrieved passages with their source references. | | Total Found | How many matched before the top-K cut. | **Scoping:** the matter comes from the run launcher, not from this step. You pick it once when you click Run, and every retrieval step in the workflow inherits that scope. *** ## Search US Case Law Deterministic Medium Searches US federal and state case opinions. **Config** | Field | Type | Required | Default | Notes | | ----------------- | ------- | -------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------- | | Query | Text | Yes | | Natural language, boolean operators supported. | | Court | Text | No | | `federal` for all federal courts, a single court code such as `scotus` or `ca9`, or several comma-separated codes such as `ca2,sdny`. | | Filed on or after | Date | No | | ISO `YYYY-MM-DD`. | | Number of results | Integer | No | 5 | 1 to 50. | **Outputs** | Field | Contents | | --------------- | ----------------------------------- | | Cases | The matching opinions. | | Total Available | Total matches before the top-K cut. | *** ## Lookup US Statute Deterministic Medium Keyword search across US federal statutes, regulations, and state codes. **Config** | Field | Type | Required | Default | Notes | | ------------------------- | --------------------------- | -------- | ------- | ------------------------------------------------------------------------------ | | Query | Text | Yes | | Boolean operators supported. | | Source | USC, CFR, Executive Actions | No | | The federal source to query. | | State | Text | No | | Restrict to a single state's statutes. | | USC title number | Integer | No | | 1 to 99. For example 17 for Copyright, 15 for Commerce. | | Include repealed sections | Boolean | No | off | By default repealed, omitted, transferred, and reserved sections are excluded. | | Number of results | Integer | No | 5 | 1 to 50. | **Outputs** | Field | Contents | | --------------- | ----------------------------------- | | Statutes | The matching sections. | | Total Available | Total matches before the top-K cut. | *** ## US Statute Cross-References Deterministic Fast Pulls cross-references, the authority chain, and amendment history for one section. No model call, sub-second. **Config** Provide **one** of: | Field | Type | Notes | | ---------- | ---- | -------------------------------------------------------------------------------------------------------------------------------------------- | | Section ID | Text | The canonical exact key, for example `CFR_T7_P2_S2_601`. Emitted by an upstream Lookup US Statute step, which makes it the preferred wiring. | | Citation | Text | The human-readable form, for example `7 C.F.R. § 2.601` or `Cal. Civ. Code § 1798.100`. Used when no section ID is available. | **Outputs** | Field | Contents | | ------------------------------------------------------------- | -------------------------------- | | Found | Whether the section was located. | | Act Id, Citation, Citation Short, Section Title, Display Path | Identity of the section. | | Act Status, State | Status and jurisdiction. | | Cross References Usc, Cross References Cfr | Sections this one points at. | | Statutory Authority | The authority chain. | | Amendment Years, Last Amended Year | Amendment history. | | Federal Register Citations | Federal Register references. | | R2 Section Text Url | Link to the full section text. | Chain **Lookup US Statute → US Statute Cross-References** and wire the first hit's section ID. That gives you the authority chain and amendment history for the section your query found, at effectively no cost. *** ## Web Search Deterministic Medium Web search for legal news and regulatory updates, restricted to US sources by default and hardened against SSRF. **Config** | Field | Type | Required | Default | Notes | | ----------------- | ------- | -------- | ------- | ------------------------------------------------------------------------------------------------- | | Query | Text | Yes | | Up to 2,000 characters. | | Number of results | Integer | No | 5 | 1 to 25. | | Recency (days) | Integer | No | | 1 to 365. Only results published in the last N days. Useful for breaking regulatory developments. | **Outputs** | Field | Contents | | ------- | ----------------------------------- | | Results | The web results with their sources. | *** ## Related Turning retrieved material into structured output.
