Tools of SENTINEL Washington Real Estate
	Description		Read-only	Idempotent	Open world
`nwmls_deadlines`Compute the standard NWMLS transaction deadline set from a mutual-acceptance date: earnest money (Form 21), seller disclosure delivery + buyer rescission (Form 17, RCW 64.06), title contingency (Form 22T), inspection (Form 35), financing (Form 22A), and FIRPTA certification (Form 22E). Business-day counts exclude weekends and Washington state holidays per RCW 1.16.050 — never plain calendar arithmetic. Washington/NWMLS transactions only. Dates are the standard form DEFAULTS computed from public rules (no NWMLS data or form text); the result flags dates landing on non-business days and includes a verify-against-the-executed-contract disclaimer that must accompany any advice built on these dates. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

`wa_comps`Find recorded home sales around an address (radius), inside a drawn neighborhood outline (polygon of [latitude, longitude] points) or in a ZIP code, over the last 1-36 months, filtered by beds, baths, living sq ft, year built, price and property type. Returns each sale (address, date, price, price per sq ft, size, distance; no owner, buyer or seller names), median and quartile price and price per sq ft, a half-over-half trend, a price band when subjectSqft is given (or known from the county record), chart-ready series (chart.points, chart.monthly_median) and chart.image_url, a signed SVG chart an agent can open, save and show a seller. Use it for 'what did 3 bed homes near this street sell for in the last year' or 'what should we list at'. Show the chart (draw it from the series, or link chart.image_url) and quote the numbers exactly. King, Pierce and Snohomish county assessor records only; Snohomish has year built and property class but no size or bedrooms, and its dates are sale months.

`wa_local_context`Get aggregate Census housing tenure estimates and margins of error by ZIP/ZCTA, nearby published Metro boarding stops by coordinate, and factual OSPI language programs by county, district or exact four-digit schoolCode. Combined school filters must all match. Sources have independent coverage, timestamps and required attributions. Does not determine school attendance, quality, neighborhood suitability or walking time. Supply a geography, schoolCode or supported research identifier; latitude and longitude must be paired.

`wa_market_snapshot`Latest Redfin market snapshot for a Washington area — ZIP code, neighborhood, city, or county: median sale price, year-over-year change, days on market, months of supply, and percent sold above list, with an explicit data-freshness period. Western Washington focus. Aggregate statistics only — no individual listings, parcels, or people. Use for 'how is the market in X' questions; quote the returned numbers verbatim and reproduce the Redfin attribution (required) wherever the numbers are shown. Paused while Sentinel arranges a licensed sale-statistics source: it then answers SOURCE_UNAVAILABLE, uncharged.

Use for 'what will the seller walk away with' questions on WA sales; WA counties only. The result is an itemized dict. Uses no third-party data.

`wa_permit_history`Read dated building-permit records for one exact property, including agency status, application/issue/completion dates, unit counts, project cost, zoning labels and observed changes. Connected sources are Seattle building permits, Everett permits and Pierce County PALS records; this is not complete city/county coverage. Other municipal sources return official lookup resources while commercial permission is unresolved. Use address or county plus parcelId. Match uses exact county/parcel or recorded street, unit and ZIP; no records does not prove no permits, and permit labels do not establish current development rights. Source update times may represent a bulk republish; distinguish source dates from observation time.

`wa_property_changes`Read immutable permit evidence for an exactly matched property. Supply since for changes after that capture time, or asOf for versions known by that time. Permit event dates are separate from Sentinel observation/capture times. Initial captures are baselines, not changes. History starts at first immutable capture and is incomplete; unavailable history is free. Use next_cursor with unchanged inputs to continue a bounded page. Never infer unpermitted work.

`wa_property_lookup`Look up one Washington property from already-ingested county assessor records (King, Pierce, Snohomish, Whatcom counties). Returns cached property facts with field-level source observations and explicit unverified, missing, withheld and stale states: physical attributes, assessed values, last recorded sale, ownership tenure, and a coverage_note naming any fields the county extract lacks. Listing status, list price and days on market are populated only when the matched listing row came from a licensed listing provider (fields: listing_status, list_price, dom, listed_date, removed_date, listing_source, listing_status_source, listing_fetched_at, listing_attribution). When the only match is a scraped portal row, or no listing matched, all of them are null — which is the usual case today. Read a null as 'no licensed listing on file for this address', not as 'this home is not for sale', and do not infer a status or a price from the county fields. Owner identity fields (owner or taxpayer names, mailing addresses, owner-status classification) and equity estimates are not included in this version. Listing links, listing photos and portal automated valuations are not returned. Per-address queries only (RCW 42.56.070(8)); no area enumeration. Use a specific WA street address or county plus parcelId; a NOT_FOUND error means the address is outside covered counties or not in the ingested rows — say so rather than guessing.

`wa_reet`Calculate Washington State Real Estate Excise Tax (REET, RCW 82.45) for one sale: graduated state brackets plus the county's local rate, computed deterministically by SENTINEL's production engine — never estimated. Use when you need the exact excise tax owed on a WA home sale (seller-paid by default). Washington State counties only. The result includes the per-bracket breakdown, the $5 DOR technology fee, and rate-assumption caveats (verify the DOR location code for city-level exceptions). Uses no third-party data.

`wa_research_packet`Get a bounded property research packet with exact identity matching, source-backed facts, explicit calculations, conflicts, unknowns and follow-up questions. Compact and full projections retain identical claims, references and required notices. Optional coordinate context is a separate point observation, never an inferred parcel match. Preserve every qualification. Unavailable or ambiguous research is free; useful partial evidence counts as one answer.

`wa_sale_history`Read recorded sale dates and prices for one exact King, Pierce or Snohomish County parcel, from the county assessor's own published sale records (up to the last three years). Each record gives the parcel count, the county's market-validity code and whether it can serve as a comparable sale; multi-parcel, nominal and unverified prices are flagged, not hidden. No buyer, seller or owner names. Use address or county plus parcelId. A miss is not an answer and is not charged; missing records do not prove that no sale occurred, and a sale price is not a current value.

`wa_seller_packet`Prepare one seller briefing that combines proposed sale-price scenarios with available county property records and dated market context (licensed listing and price-index trends when sale-price snapshots are paused). Includes assumptions, missing information and source attributions. Missing or old data must remain visible; supplied prices are scenarios, not a CMA or appraisal.

`wa_site_context`Query FEMA flood mapping, WGS landslide study coverage and inventory, liquefaction, mapped faults within 5 km, and an official Ecology cleanup lookup link. Cleanup site observations require documented commercial reuse permission. Supply a verified coordinate; results describe a point, not an entire parcel or structure. Each source declares unavailable/outside-study/no-mapped-feature states, observation times and required attributions. No absence claim establishes safety, disclosure compliance or insurance requirements.
