getCryptoNews

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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds that results include headlines, snippets, and URLs but does not disclose pagination behavior, rate limits, or authentication needs. Adequate but minimal value beyond annotations.

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?

A single, well-structured sentence that front-loads the purpose ('Stay informed with latest cryptocurrency news') and includes key result details. Every word earns its place.

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 4 parameters and no output schema. The description mentions headline, snippet, and URL fields but omits details on pagination behavior and date range effect. Adequate for a simple tool but missing modest additional context.

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%, so baseline is 3. The description does not add any meaning beyond the schema parameter descriptions (from_date, to, page, limit). No elaboration on date format or pagination.

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 the tool retrieves cryptocurrency news with specific verbs ('stay informed' and 'access') and resource ('cryptocurrency news articles'). It distinguishes from siblings like searchCryptoNews (focused on search) and other news tools (forex, stock).

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 implies general crypto news retrieval but does not explicitly state when to use this versus alternatives like searchCryptoNews, getGeneralNews, or stock-specific news tools. No exclusions or context are provided.

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