get_newsflash

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

No annotations are provided to indicate read-only or destructive nature. The description does not disclose any behavioral traits beyond what the schema already conveys (e.g., pagination, permission requirements, or return format).

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 a single sentence that front-loads the purpose. It is concise and contains no extraneous information, though it could benefit from minor structural improvements (e.g., bullet points for clarity).

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 has no output schema, and the description does not clarify return format or behavior (e.g., default pagination, sorting). For a list-retrieval tool, this is adequate but could be improved by mentioning typical response structure.

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 the description adds little beyond what the schema already provides for parameters like category and lang. The category list is repeated, but no new semantic information is given.

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 specifies the verb 'get' and the resource 'cryptocurrency newsflash', distinguishing it from siblings like get_newsflash_24h (24-hour version) and search_news (search vs. list retrieval).

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 lists filtering options but provides no guidance on when to use this tool versus alternatives (e.g., get_newsflash_24h, search_news). No when-not-to-use or exclusion criteria are included.

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