Behavior2/5

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

With no annotations, the description must disclose behavioral traits. It only states 'Read rows' without confirming it is read-only, safe, or idempotent. It does not mention pagination, rate limits, authentication, or response format. The description is insufficient for an agent to understand the tool's impact.

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

Conciseness3/5

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

The description is a single sentence, which is concise but under-specified. It could include more details without being verbose. While front-loaded with the main action, it omits necessary parameter context and usage hints.

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

Completeness2/5

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

Despite having an output schema, the description does not hint at what the output contains (e.g., rows, columns, structure). It also lacks information on filtering capabilities (e.g., SoQL), parameter constraints, or error handling. For a data query tool, this description is incomplete.

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

Parameters2/5

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

Schema description coverage is 0%. The description adds meaning to dataset_id (four-character) but does not explain domain (e.g., format) or limit (default 100, max? pagination). With no schema descriptions, the tool description should compensate for all parameters but fails to do so.

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

Purpose4/5

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

The description clearly states the tool reads rows from a Socrata dataset, specifying the key inputs: domain and four-character dataset ID. It distinguishes from sibling tools like search_socrata_catalog (which searches for datasets) and query_arcgis_feature_service (which queries ArcGIS).

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

Usage Guidelines2/5

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

No usage guidance is provided. The description does not indicate when to use this tool versus alternatives such as query_arcgis_feature_service or find_us_data_sources. There is no mention of prerequisites, limitations, or when not to use the tool.

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