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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds nothing behavioral: it never mentions the pagination that the 'page' parameter implies, result counts, or how sections are scoped.

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, and the resource is stated before the field list. It wastes some space enumerating return values that the output schema already provides, but it is not bloated.

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 an output schema present, listing return fields is redundant, while the genuinely missing pieces - section value format and page/pagination semantics - are absent. For a parameterized open-world browsing tool, this leaves the agent under-informed.

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 0%, so the description must carry the burden and does not. 'Section' appears only as prose with no hint of accepted values or format, and 'page' is never referenced at all. Instead the sentence spends its words enumerating return fields that the output schema already defines.

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 resource and scope: 'the latest stories in a Financial Times section.' An agent can tell it returns a list rather than a single article. However, it never differentiates itself from the sibling ft_news or ft_search, which sound like they could return the same thing.

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 on when to pick this over ft_news, ft_search, ft_categories, or ft_article, and no prerequisites. The agent must infer the intended use purely from the name and the word 'section'.

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