get_articles_by_date

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

The description discloses the hard limit of 20 results per page, which is a key behavioral trait. With no annotations, this adds some transparency, but other behaviors like sorting, errors, or authentication are omitted.

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 is very short and to the point, but contains a typo ('by Date' with double space) and lacks proper punctuation. It is concise but minimally structured.

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?

Given three required parameters, no annotations, and many sibling tools, the description is incomplete. It fails to explain pagination beyond the limit, return format, or ordering, leaving many contextual gaps.

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 coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond the schema; it merely restates the limit already in the schema.

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 states 'Get Articles by Date' clearly indicating the verb and resource. However, it does not differentiate from sibling tools like get_articles_by_date_and_author_id or get_articles_by_date_range, relying on the name alone.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of context, exclusions, or when not to use it.

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