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

Annotations already mark idempotentHint=true and destructiveHint=false. The description adds meaningful context: it records privacy-safe telemetry (a side effect) and mentions attribution-verified content and canonical links. This goes beyond what annotations state, though it does not contradict them.

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?

Two sentences, front-loaded with purpose and features, and a brief mention of telemetry. No wasted words; every clause contributes to agent understanding.

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 tool with two optional params, an output schema, and clear annotations, the description covers purpose, filtering, and side effects. It does not mention pagination or defaults, but those are in the schema. It is sufficiently complete for correct 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 description coverage is 100% (both limit and category have descriptive schema text). The description only restates 'optionally filtered by category' without adding new meaning, so it does not exceed the baseline for fully-covered schemas.

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 clearly states the verb ('Get'), the resource ('newest attribution-verified public podcast moments'), optional filtering, and canonical links. It differentiates from siblings like search_moments and list_shows by focusing on recency.

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 use for browsing the newest moments but does not explicitly contrast with search_moments or other alternatives. It mentions optional category filtering but provides no guidance on when not to use this tool or when to prefer a sibling.

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