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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety and consistency profile is fully covered. The description adds only topical scope, no pagination, ordering, or defaulting behavior, which is acceptable given the annotation coverage but adds little.

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 front-loaded sentence with no filler; the resource and its scope appear immediately.

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?

With no output schema and 0% parameter description coverage, the description should carry the burden of explaining the returned item shape and filters, but it does neither. For a four-parameter filtered list tool, this leaves an agent guessing about defaults and result 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 0% for four parameters (lang, limit, network, severity), and the description explains none of them. The severity enum (info/warn/critical) loosely maps to the listed news categories, but language, result cap, and network filtering are left entirely undocumented.

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?

States a specific verb ('List') and resource ('Clickwise news announcements about affiliate programs') and enumerates the content types covered (policy changes, launches, shutdowns, commission updates). It is clear what the tool returns, but it never distinguishes itself from the sibling get_news, leaving the list-vs-get split to inference.

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 when-to-use or when-not-to-use guidance, and no prerequisite or alternative named. An agent facing both list_news and get_news gets no signal about which to pick.

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