aggregate_overpass_h3

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

With no annotations, the description bears full burden but only states 'executes and bins'. It does not disclose if the query is read-only, any side effects, rate limits, or the structure of the output (e.g., hexagon counts). This omission significantly reduces transparency.

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

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

A single sentence of 18 words efficiently conveys the core action. It is front-loaded with the main verb and resource, with no filler or redundancy.

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

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

Despite low complexity (4 params, oneOf), the description fails to explain the mutual exclusivity of location/bbox, the output format, or how the H3 binning works. An agent cannot fully understand the tool's behavior without additional context.

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

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

Schema description coverage is 100%, so the description adds limited value. It relates 'resolution' to binning but adds no new meaning for location, bbox, or query beyond their schema descriptions. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool executes an Overpass query and bins results into H3 hexagons, a specific verb and resource. It distinguishes from siblings like search_overpass (raw results) and get_h3_indices (just indices) by emphasizing spatial density analysis.

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

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

The description provides no explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites, when-not-to-use, or that location and bbox are mutually exclusive (only implied by schema).

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