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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful context that the response blends three distinct collections, which hints at heterogeneous output shapes, but it says nothing about pagination, ordering, or how the collections are merged.

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 efficient sentence with no filler, and the resource is front-loaded. It is well-sized for the amount of information conveyed, though that brevity contributes to the gaps elsewhere.

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-value details need not be spelled out, and the read-only nature is covered by annotations. However, with one fully undocumented parameter and no usage context, the definition is only minimally sufficient 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 0% and the single parameter (limit) is undocumented in both the schema and the description. The description never mentions limiting or result-size behavior, so the agent is left to guess what limit controls and its default.

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 verb (returns) and resource (metadata from Cricinfo's public video hub), and enumerates the collection types it aggregates (curated, trending, genre-associated). It does not explicitly contrast itself with sibling content tools like cricinfo_news or cricinfo_photos, so an agent must infer that this is the video-specific endpoint.

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?

There is no when-to-use or when-not-to-use guidance, and no alternatives are named. The description tells the agent what the tool returns but not under which circumstances it should be chosen over other Cricinfo tools.

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