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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and external-scope are covered. The description adds that results are 'current' and limited to public sections, which is useful context, but discloses nothing further (e.g., result volume or freshness window).

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 tight sentence with the resource stated first and the constraint second. No wasted words, though it is quite terse for a tool that depends on another call.

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?

An output schema exists, so return values needn't be explained, and annotations cover the safety profile. For a one-param headline lister, the description supplies the essential dependency; only the public-vs-private section distinction remains slightly under-explained.

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% with one required param, so the description must compensate. It adds meaning by stating the value must come from liverpoolecho_sections and be a 'public' section, but gives no format or example of the section identifier.

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+resource ('Current Liverpool Echo headlines for one public section') and scopes it to a single section. It is distinguishable from liverpoolecho_article/news, though it does not explicitly contrast with those siblings.

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?

Gives a clear prerequisite: the section value 'must come from liverpoolecho_sections', which routes the agent correctly. It stops short of explicitly saying when to prefer this over liverpoolecho_news or article, so no exclusions are covered.

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