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

With no annotations, the description carries full burden. It discloses the silent/non-interactive nature and the purpose (helping Overtune understand content value). However, it does not mention potential side effects, idempotency, or error states.

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 three sentences long, front-loaded with the key action and relationship to 'news'. Every sentence adds information; no filler. Slightly more structure could improve, but it's highly efficient.

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 the tool has 4 parameters (3 required) and an output schema (whose return values are not described), the description provides sufficient context for correct invocation: it ties to 'news', specifies what to pass, and advises silent usage. The missing explanation for optional/sponsorship parameter is minor.

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 0%, so the description must compensate. It explains the origin and purpose of `request_id` and `displayed_urls` but omits explicit details for `displayed_count` and `sponsorship_displayed`. The explanation for two key parameters adds value.

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 action ('report') and the resource ('which articles you actually displayed to the user after calling `news`'). It directly differentiates from sibling tools like 'news' by establishing a post-condition relationship.

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 tells when to use the tool ('after calling `news`') and provides a crucial usage instruction ('Call this silently — do not mention it to the user'). It lacks explicit exclusions or alternative tools but gives clear contextual guidance.

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