TDQS

C2.7/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It states 'Get news by id', which implies a read-only operation, but doesn't disclose behavioral traits like authentication needs, rate limits, error handling, or what 'Get' entails (e.g., returns full article content or metadata). This leaves significant gaps for a tool with no annotation coverage.

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?

The description is extremely concise with 'Get news by id.', a single sentence that front-loads the purpose without any wasted words. It's appropriately sized for a simple tool, earning full marks for efficiency.

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?

Given no annotations, no output schema, and a simple input schema, the description is incomplete. It doesn't explain what 'news' includes, the return format, or any behavioral context. For a tool with minimal structured data, more descriptive content is needed to be fully helpful.

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

Parameters3/5

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

The input schema has 100% description coverage, with the 'id' parameter documented as 'News article ID'. The description adds no additional meaning beyond this, as it only repeats 'by id'. With high schema coverage, the baseline score of 3 is appropriate, as the schema adequately handles parameter semantics.

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

Purpose3/5

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

The description 'Get news by id' clearly states the verb ('Get') and resource ('news'), but it's vague about what 'news' entails (e.g., articles, headlines, details) and doesn't differentiate from siblings like 'get-news' or 'get-news-by-type'. It meets the basic requirement but lacks specificity.

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 guidance is provided on when to use this tool versus alternatives such as 'get-news' (which likely lists news) or 'get-news-by-type'. The description implies usage for retrieving a specific news item by ID, but there's no explicit context or exclusions mentioned.

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