find_in_section
Find in section
Returns only the verbatim paragraphs of one obligation (section) that contain the given terms. Inputs: `obligation_id`; `terms`, 1-6 short words or phrases ("cash-out", "credit score", "LTV"; abbreviations are expanded; numbers match as words or digits, so "five years" finds "five (5) years"); optional `max_passages`. Each passage has `verbatim` (the regulator's exact text), `offset` (its position in the section's text), `canonical_citation` (the pinpoint cite, where derivable) and `heading_path` (every heading above it, e.g. "vi. No Cash-Out Refinances > (A) Rate and Term > (i) Standard"). A match inside a table returns the whole table (`table: true`; `table_layout: "flattened"` when the source lost its layout and cells may not line up). A passage ending in a colon includes the list it introduces (`list_included: true`). `truncated` means more passages matched than were returned. No passages means no paragraph contains the terms as given; it is not a statement about the rule. `currency` is null or a version/status signal (dual-version, pending, revision-pending, superseded, expired...). On an FHA section HUD's Update 18 revises, `version` ("in-force" or "update-18-optional") says which text this is and `other_version` identifies the other.

get_obligation
Get obligation
Returns one obligation's (section's) verbatim regulator text with provenance. Inputs: `obligation_id`; optional `offset`, `limit`, `compare_versions`. `verbatim` holds the text between <<<BEGIN VERBATIM>>> and <<<END VERBATIM>>>. `canonical_citation` is the section's citation in the regulator's style (e.g. "4000.1 II.A.5.d", "B3-3.3-07", "38 U.S.C. 3709(b)"), or null. Paging: at most 24,000 chars per response; `chars_offset` + `chars_returned` is the position within `chars_total`; `next_offset` is the offset of the next page, or null when the section ends in this response; `truncated` means more text follows; `started_mid_section` means text before `chars_offset` is not included; `paging` gives page N of M. `currency` is null or a version/status signal (dual-version, pending, revision-pending, superseded, expired...) with a one-line `headline`. An FHA 4000.1 section HUD's Update 18 revises has two obligations, the in-force text and the revision (`<id>::update-18`); `version` says which this is and `other_version` identifies the other. `compare_versions: true` adds `version_changes`, the sentences Update 18 deletes and adds. `figures` is a best-effort extraction of figures in the text; an empty or incomplete list is not evidence that the text states no figure. `canonical_id`, when set, is the register this one is a same-text copy of.

get_playbook_kit
Get playbook kit
Returns a playbook's rule kit. FNMA AI lender letter: the verbatim LL-2026-04, InfoSec Supplement and ECOA/Reg B/FCRA/AVM rows with citations, paginated; `next_offset` is the next page's offset, or null when the kit is complete. FHA/VA/USDA QC: the corpus registers each check area is grounded in. The kit block's fingerprint and dates identify its version. Playbook tools accept only ids and reference names, no document text; the user's P&Ps and loan files stay in their own chat.

get_reg
Get regulation
Returns a manifest of one register (source document): its provenance, `currency` (null or a version/status signal: dual-version, pending revision, superseded, expired...) and its obligations (sections), each with `obligation_id`, section, `canonical_citation`, `chars_total` and `will_truncate` (true when the section exceeds one 24,000-char page). The manifest contains no regulator text. A dual-version section lists both obligations, each with `version` ("in-force" or "update-18-optional") and `other_version`.

lookup_citation
Look up citation
Resolves a regulatory citation (e.g. '4000.1 II.A.8.d', 'B3-4.3-04', 'Freddie Mac Guide 5306.1', '38 U.S.C. 3737', 'M26-7 Chapter 4 Topic 9', 'SBA Notice 5000-872764', 'SOP 50 10 8 B.Ch1.A.2', 'HB-1-3555 11.3') to a `register_id`. Errors: `not_found` (the cite parses but is not in the corpus; `parsed` shows the parse), `ambiguous` (it could mean several registers, listed in `candidates`; no guess is made), `unparsed` (not recognizable as a citation). Near matches are not suggested. A handbook section resolves to the handbook's own register; documents that cite or amend it (e.g. Mortgagee Letters) are listed in `related` and are not the section's text. Identical copies of a section resolve to one register and are listed in `also_at`. A whole-handbook name returns `handbook`, an outline of its parts.

search_regs
Search regulations
Full-text search of US mortgage regulator text (Fannie Mae, Freddie Mac, FHA, VA, USDA, Ginnie Mae, SBA, CFPB). Inputs: `query`; optional `family` (one agency), `limit` (1-25), `currency_kind` (only sections carrying that currency signal; "any" = any signal). Common abbreviations (DTI, LTV, IRRRL, W-2, VOE, PITI, BK...) are expanded to the regulator's terms. Each result is one section: title, `obligation_id`, `canonical_citation` (the citation in the regulator's style, or null) and `excerpt`, a verbatim fragment near the match, not the whole rule. `match` is "all_terms" or "partial"; a partial result lists the query words it lacks in `missing_terms`. Order: `rank_score`, highest first = text score (title-weighted) x term coverage x title fit, with superseded, pending, incorporated or expired text x0.2 (never above its replacement), a special program's section (`special_program`: Home Possible, HomeReady, 203(k), HECM...) x0.5 unless the query names the program, and `obligation_type` "note" (statutory source-credit and editorial notes) or "index" (a chapter heading) x0.2 unless the query asks for them. `section_status` "deleted" marks a deleted-section stub, ranked last. A query that is a citation ("38 U.S.C. 3737", "ML 2026-08") returns the cited section first and sets `cited`; a bare handbook name ("HUD 4000.1") adds `handbook`, an outline of its parts. `currency` is null or a version/status signal whose kinds include dual-version, pending, revision-pending, superseded, superseded-in-part (a Mortgagee Letter replaced some provisions, named in `headline`), modified-by (a later issuance changes it, optional until its mandatory date) and expired. `version` "in-force" or "update-18-optional" marks the two texts of an FHA section HUD's Update 18 revises (`mandatory_date` for the revision); `other_version` is the other text's obligation_id. Empty results carry `reason` (empty_query, no_match, no_match_above_threshold) and may carry `guidance` naming shorthand in the query.

start_playbook
Start playbook
Returns one playbook's full workflow instructions, its stages, the stage reference names and the rule-kit version: the Fannie Mae AI lender letter (LL-2026-04) P&P review, or FHA, VA or USDA loan-file QC. Input: the playbook `id`; an unknown id returns `unknown_playbook` with `valid_ids`. Playbook tools accept only ids and reference names, no document text; the user's P&Ps and loan files stay in their own chat.

verify_quote
Verify quote
Checks whether a passage appears in a regulator's source document; accepts text from any source. Inputs: `text` (up to 5,000 words); optional `register_id` (without it, up to 3 candidate documents are located by search). `outcome` is one of: exact (contiguous in the source, quote marks and dashes as the source writes them; a line break counts as a space); normalized (matches after folding quote and dash typography, `typography_folded`; ignoring page footers or running heads, `furniture_ignored`; spacing where the stored source splits or joins words, `spacing_ignored`; or added list markers, `list_markers_ignored`); composed (every word is in the source, in source order, but from non-contiguous pieces, as with an overview or an ellipsis; `omissions` lists the short source phrases skipped between pieces); not_found (no source support; `unsupported` lists the unsupported spans, and on a near miss `differences` gives the closest source text, the source words the text lacks and the words it adds); not_checked (over 5,000 words). `coverage` is the share of words found. `checked_against` names the documents checked (document, edition, retrieval date; ids in `checked_snapshot_ids`); `matched_against` names the one matched, `matched_register_id` / `matched_obligation_id` the stored text containing the passage. `matched_version` is current; superseded (the text is a prior version of the rule; `superseded_by` is the current register); or update-18-optional (HUD's Update 18 revision of an FHA 4000.1 section, optional until `mandatory_date`; `in_force_obligation_id` is the text in force by default). `obligation_currency` lists currency signals on the obligation holding the text (e.g. superseded-in-part). `rescinded: true` (with `rescinded_by`) means the passage is text a later issuance removed or replaced.
