A3.9/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering safety and external data. The description adds value by specifying the exact output focus (cadence, episode length, latest episodes) and the 'any feed' scope, which matches the openWorldHint. No contradictions, and no adverse behavior is omitted that would be expected for a read-only fetch.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the action and scope, then states the output. No wasted words; every phrase contributes to understanding the tool's purpose and result.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With two parameters and no output schema, the description leaves the 'episodes' parameter unmentioned and does not specify how many episodes are included in 'latest episodes' or the exact return structure. The openWorldHint suggests external content but no error handling or edge cases are addressed. An agent would not know how to correctly set 'episodes' without further inference.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%. The description indirectly clarifies feed_url via 'any podcast's RSS feed', but it does not explain the 'episodes' parameter at all. The agent has to infer that 'episodes' likely controls how many latest episodes to return, and the default of 5 is not mentioned. With zero schema coverage, the description must compensate and fails to do so for the optional parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Fetch') and resource ('any podcast's RSS feed'), clearly stating what is returned (cadence, typical episode length, latest episodes). It distinguishes itself from sibling tools like roulette, trending, and listing tools, all of which imply different actions or targets.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context: use this tool to fetch a podcast feed and get summary stats. It does not explicitly name alternatives or exclusions, but the purpose is distinct enough from the siblings that an agent would not confuse it. There is no explicit 'when not to use' guidance, so it falls short of a 5.

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