get_parcel_report

Read-only

The whole dossier for one land parcel in a single call: the parcel core (location, area, land use, plan designation), all thirteen enrichment layers (flood risk, heritage listing, landslide risk, subsurface: mining terrains and major groundwater reservoirs, nuisance surroundings, public-transport access, general-plan zoning, buildings on the parcel, recent building activity, agricultural-land eligibility, official land-use & soil-quality classification with its re-designation consequences where the county publishes it, nature: nearby forest and protected areas, roads: geometric road-access evidence measured from carriageway centrelines, which is not a determination of legal access), the parcel's transaction history (newest first, up to 20), a local price context (median zł/m² for the county and the locality over the last 12 months) and a municipal context (a headline demographic/economic subset plus upcoming-infrastructure signals for the gmina). Address it by a full cadastral id in the natural '/' form ('142907_2.0014.342/5'), the URL-safe '-' form, or the internal UUID from a search or resolve result. Each section carries its own state, shown explicitly: covered = a definitive result; covered_no_data = the parcel was checked and nothing was found (still billed); not_covered = outside our data (refunded); not_computed = a live computation could not finish in time (refunded — the rest of the report still returns, so a report can be partial). The two context sections instead use full / low_sample / suppressed / no_data. The buildings section additionally reports how many of the buildings could be given a construction-age estimate from building-permit records. That is an ESTIMATE with an interval, never a registry construction date, and the records only start in 2016, so for most buildings the answer is that the year could not be established — which is stated rather than omitted. Prefer this over calling the per-layer parcel tools one by one — it is one call at a flat price and never costs more than the sum of its parts. Use resolve_parcel first when you only have an address, a coordinate, or a 'locality + number'. Costs 45 API tokens. Billing is by outcome (see the billing line on the response): a parcel that cannot be resolved is fully refunded; a resolved parcel where no layer had data is billed only the core floor (1 token) with the rest refunded; a resolved parcel with at least one covered layer is billed in full.

A4.9/5.0
Behavior5/5

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

Beyond the readOnlyHint/destructiveHint annotations, the description explains per-section state semantics (covered, covered_no_data, not_covered, not_computed), billing and refund behavior, partial-report behavior, and the buildings construction-age estimate caveat with its 2016 data limitation. There is no contradiction with annotations.

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

Conciseness5/5

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

Though long, every paragraph earns its place: contents, ID formats, section states, the buildings estimate caveat, usage preference, and billing. The most important one-line definition is front-loaded, with supporting detail organized clearly afterward.

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

Completeness5/5

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

For a tool with one parameter and no output schema, the description is remarkably complete. It tells the agent what sections to expect, how each section's state should be interpreted, what gets refunded, what a partial report means, and what the token cost is. An agent can confidently select and invoke this tool without additional information.

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?

The schema already describes parcelId at 100% coverage, so the baseline is 3. The description adds value by giving concrete accepted forms ('142907_2.0014.342/5', the '-' form, or the internal UUID from a search/resolve result) and by connecting ID resolution to resolve_parcel. This goes slightly beyond the schema without being redundant.

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?

The description opens with a specific verb and resource: 'The whole dossier for one land parcel in a single call.' It then enumerates exactly what the report contains, including core parcel data, enrichment layers, transaction history, price context, and municipal context. This clearly distinguishes it from sibling per-layer tools such as get_flood_risk or get_transaction_roads.

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?

The description gives explicit routing guidance: 'Prefer this over calling the per-layer parcel tools one by one' and 'Use resolve_parcel first when you only have an address, a coordinate, or a locality + number.' This tells the agent exactly when to use this tool versus alternatives.

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