TDQS

B3/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, closed-world and non-destructive, so the safety profile is covered. The description adds only a disclaimer ('not legal advice') and does not say how missing or invalid keys behave or whether key matching is case-sensitive. That is modest added value above the annotation baseline.

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?

Two tight sentences, front-loaded with the core action and scope. The illustrative list is slightly loose but earns its place by hinting at dataset content; the legal-advice disclaimer is the only filler.

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

Completeness3/5

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

An output schema exists, so return-shape explanation is not owed. However, for a tool whose main difficulty is choosing one of 56 datasets and formatting a key, the description leaves both discovery and formatting unresolved and never points to list_datasets.

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 coverage is only 33% and the description does not compensate: the 56-value dataset enum is opaque and nothing maps the examples (limitation periods, lawyers per resident) back to enum values like 'limitations' or 'lawyer-wages'. The response_format parameter (concise vs detailed) is never mentioned at all.

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?

States a concrete verb and resource: fetch figures for a single key (state, county, etc.) from a single open dataset, with illustrative metric examples. It is clear what the call returns, but nothing distinguishes it from siblings like data_search or data_compare, which plausibly do multi-key or cross-dataset work.

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 indication of when to pick this over data_search, data_compare or compare_states, and no guidance on prerequisites such as discovering valid dataset identifiers (list_datasets is a sibling but is never mentioned). The reader is left to infer the single-key scope from the examples alone.

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