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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds only that the collections are "public" and that results are "canonical page links," which is mild extra context; nothing is said about pagination behavior or ordering.

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 short sentence with no filler and the resource front-loaded. It is not bloated, though its brevity edges toward under-specification rather than efficient precision.

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 the safety profile. However, for a 5-parameter, enum-bearing listing tool with zero schema descriptions, the description leaves too much (filtering, pagination, kind semantics) undocumented.

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?

All five parameters (kind, page, limit, query, language) have 0% schema description coverage, and the description mentions none of them. An agent cannot learn from it how kind=topic differs from kind=genre, what query filters, or how page/limit interact.

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 ("Find") and resource ("public genre/topic collections and canonical page links"), which reads as a browse/catalog action distinct from the search_* siblings. It does not explicitly name the search_* tools it competes with, so the differentiation is only implied.

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 statement of when to use this over search, search_documentaries, or recommend_documentaries. The browse-vs-search distinction is left entirely to inference from the tool name and the sibling list.

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