get_articles_by_date_range

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

No annotations are provided, so the description bears the full burden of behavioral disclosure. It reveals the hard pagination limit (max 20 per page), which is useful. However, it does not disclose authentication requirements, rate limits, mutability, or any other behavioral traits. For a read operation with no annotations, more transparency is expected.

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?

The description consists of two short sentences. The first sentence states the core purpose, and the second adds a critical behavioral detail. There is no unnecessary verbiage, and the information is efficiently front-loaded.

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?

The tool lacks an output schema, and the description does not explain what is returned (e.g., article details, metadata) or the structure of the response. Additionally, it does not clarify whether the tool returns all articles in the date range or if other filters apply. The hard limit and pagination behavior are mentioned, but overall completeness is low given the absence of output schema.

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%, and each parameter has a basic description (e.g., 'Example value: 2023-11-30'). The description adds no additional meaning beyond the schema, but the schema itself is adequate. Baseline score of 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 'Get Articles by time period' which is a specific verb and resource. The tool name itself includes 'by_date_range', making the purpose unambiguous. While it does not explicitly differentiate from siblings like get_articles_by_date, the combination of name and description is sufficient.

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 mentions a hard limit of 20 results per page, which provides a usage constraint. However, it offers no guidance on when to use this tool versus siblings (e.g., get_articles_by_date for a single date) or when not to use it. This is minimal guidance.

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