get_features

Query spatial features from a collection as GeoJSON, with options to limit results, filter by bounding box, select properties, and apply property-specific filters.

Instructions

Fetch features from a collection. Returns GeoJSON.

Args: collection_id: e.g. 'boundaries-gemeente', 'boundaries-pc4', 'bop-facilities' limit: max features to return (1-100) bbox: bounding box as 'minx,miny,maxx,maxy' (WGS84) properties: comma-separated property names to include filter_param: property filter e.g. 'statnaam=Amsterdam'

Behavior3/5

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

With no annotations, the description carries full burden. It discloses the return format (GeoJSON) and describes parameters, but lacks details on pagination behavior, error handling, or constraints beyond the limit range.

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

Conciseness4/5

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

The description is concise with a clear header and structured Args list. It front-loads the purpose and every sentence adds value.

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

Completeness4/5

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

Given the 5-parameter complexity, no annotations, and presence of an output schema, the description covers essential aspects well. It lacks some behavioral context but is largely complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description compensates fully by providing examples and format for each parameter (e.g., bbox format, filter_param example, limit range). This adds significant meaning beyond the schema.

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 starts with 'Fetch features from a collection. Returns GeoJSON.' which clearly specifies the verb and resource, and distinguishes it from sibling tools like describe_collection and list_collections.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides example values for collection_id but does not explicitly state when to use this tool versus alternatives like search_boundaries or other feature-retrieval tools. Usage context is implied but not explicit.

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