TDQS

A3.7/5.0
Behavior3/5

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

Annotations already establish read-only, idempotent, non-destructive behavior, so the description only adds modest context: the resource contains four named sections and calling without filters returns recent issues. It does not disclose response format or pagination, but those are less critical given the annotations and simple GET nature.

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?

One sentence, about 30 words, with the core purpose front-loaded and no filler. Every phrase earns its place by conveying either the resource contents, the filtering options, or the fallback list behavior.

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?

For a read-only tool with zero required parameters and no output schema, the description covers what the tool returns (sections) and the two ways to invoke it (specific volume/issue or recent list). It does not address overlap with sibling congressional record tools, but within its own scope an agent has enough to select and call it correctly.

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?

Schema coverage is 100%, so the baseline is 3. The description adds value by clarifying the relationship between volume_number and issue_number as jointly used for 'specific issues,' and by indicating that omitting them lists recent issues—semantics not fully captured by the individual parameter descriptions.

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 uses a specific verb ('Get') with a clear resource ('daily Congressional Record issues') and even enumerates the section types (Senate, House, Extensions of Remarks, Daily Digest). It distinguishes from 'bound' volumes via the word 'daily,' though it does not explicitly differentiate from the sibling 'congress_congressional_record.'

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 gives clear usage modes: filter by volume and issue number for specific issues, or list recent issues. However, it never explicitly says when to prefer this tool over the similar sibling tools 'congress_congressional_record' or 'congress_bound_congressional_record,' so differentiation is left implied.

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