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 only the scoping constraint (a single public section); it says nothing about pagination, result counts, or freshness beyond the word 'current'.

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 tightly-written sentence with no filler; the scope constraint and the provenance dependency are both front-loaded.

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?

For a one-parameter read tool with full schema coverage, annotations, and an output schema, the description covers what the agent needs. Only minor gaps remain, such as how many headlines to expect or whether the list is paginated.

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 100% and the schema already lists all documented slug values, so the baseline is 3. The description adds genuine value by naming the authoritative source of those values (tomshardware_sections), which the flat enum-like list in the schema does not convey.

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 states a specific verb+resource ('Current ... headlines') and scope ('for one public section'), which is enough to distinguish it from tomshardware_article and tomshardware_sections. It does not explicitly contrast itself with the sibling tomshardware_news, so it stops short of a 5.

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?

It gives a clear prerequisite — the section value must come from tomshardware_sections — which routes the agent to the right companion tool before calling. It does not state when to prefer this tool over tomshardware_news or tomshardware_article, so it lacks explicit alternatives.

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