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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and network scope are covered. The description adds 'current' (freshness) and single-section scoping, but says nothing about payload size, ordering, or limits.

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 scoping constraint and the parameter-validity rule both earn their place.

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, return values need no explanation, and the parameter source is documented. For a one-argument list tool this is nearly enough, though pagination or result-count behavior is left unstated.

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% and the lone 'section' parameter is only typed as a bare string. The description compensates by naming the authoritative source of valid values (nydailynews_sections), which is exactly the missing semantic an agent needs.

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 (New York Daily News headlines) with a clear scope constraint (one public section), which separates it from nydailynews_article and nydailynews_news. It does not explicitly name those siblings, so an agent must infer the boundary from the shared prefix.

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 an actionable prerequisite: the section value must come from nydailynews_sections, which routes the agent to the correct companion tool for discovery. It stops short of stating when to prefer this over nydailynews_news for broader coverage.

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