  "instructions": "1. Answer in the regulator's exact words: quote each relevant section verbatim with its section citation, not a paraphrase. Summary after, labeled as a summary.\n2. State any `currency` warning and which version.\n3. Use regulator vocabulary (\"debt-to-income\" not \"DTI\"). Titles don't fit: search again.\n4. A special program's rule applies only to that program: find the general rule.\n5. Still none: the corpus doesn't address it; say so, don't answer from memory.\n6. Read: find_in_section. Verify: verify_quote.\n\nNotice: every result carries a `notice` (research only, not legal advice). Mention it ONCE per conversation, in one short line, not under every answer.\nCite `canonical_citation`. Reading: find_in_section gives the paragraphs with your terms (check `heading_path` is the program meant); get_obligation pages the whole section: repeat with offset=next_offset until null. Don't say a section lacks something before reading every page; no find_in_section match doesn't mean the rule is silent. `figures` is a best-effort extraction; an empty or incomplete list is not evidence the text states no figure.\nTwo versions (an FHA section Update 18 revises; `version` in-force / update-18-optional): quote the one that applies. If you don't know whether the user has adopted Update 18, quote the in-force text and state what the revision changes, or ask.\nsuperseded-in-part: quote the Mortgagee Letter for the replaced provisions, this text for the rest.\nverify_quote quotes before presenting them. composed: check `omissions` (a dropped \"not\" changes meaning); not_found: not a quotation; superseded: only as the prior version; update-18-optional: as the Update 18 version; rescinded: never as current.\nlookup_citation \"ambiguous\": ask the user which. daily_capacity_reached: stop for today; don't answer from memory.\nPlaybooks (FNMA LL-2026-04 P&P review; FHA, VA, USDA loan-file QC): list_playbooks, then start_playbook; follow its instructions exactly. Playbook tools take only ids: the user's documents stay in their chat, never sent here.",

      "description": "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.",

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.",
