digest

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

No annotations are provided, so the description carries the behavioral burden. It indicates the tool generates a digest and nothing else, but it does not disclose potential side effects, dependencies on feeds, rate limits, or how content is selected. Some behavior is clear, but much is left unspecified.

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 sentence that leads with the action and output format. Every word earns its place, and there is no redundant or filler content.

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 and only two optional parameters with defaults, an agent can invoke this tool with no arguments reasonably safely. However, the description omits how hours and limit interact, what 'trending topics' means, and whether the digest depends on configured feeds, leaving room for misinterpretation.

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 description does not explain 'hours' or 'limit'. The parameter names and defaults are somewhat self-explanatory, and 'recent articles' hints at hours, but the description adds no explicit parameter semantics to compensate for the schema's lack of descriptions.

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 clear verb ('Generate') and resource ('markdown digest grouping recent articles and trending topics'), making the tool's core function obvious. It does not explicitly compare itself with siblings like recent or trending, but the grouping and digest format distinguish it enough.

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?

The description implies usage: call this when you want a consolidated markdown digest of recent articles and trending topics. It does not provide explicit when-to-use versus alternatives or mention exclusions, so guidance is only implied.

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