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

Annotations already declare readOnlyHint and openWorldHint, covering the safety profile. The description adds only that the feed is public/RSS-based, implying no authentication and that it is a single-section snapshot; it says nothing about freshness, limits, or result volume.

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 no filler, front-loading the resource before the source. It is efficient, though its brevity here comes partly from omitted detail.

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 need not be explained, and annotations cover safety. However, with a zero-coverage optional parameter and no sibling differentiation, the definition is not quite complete for confident invocation.

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% and the single 'section' parameter has no description and no enum. The phrase 'one public RSS feed section' hints that section selects a feed, but gives no accepted values (e.g., news, tech, politics) or default behavior, leaving the agent unable to call it correctly.

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 the resource (Slate article headlines) and the source (one public RSS feed section), which is more than a restated name. However, it does not distinguish itself from siblings slate_article (single article) or slate_categories (section listing), so an agent must infer the boundary.

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 statement of when to use this versus slate_article or slate_categories, and no note on whether the section argument is optional or required. The agent gets no routing guidance beyond the bare subject matter.

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