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

No annotations are provided, so the description carries the full burden. It discloses the output shape and the provenance of the required token, and 'suggests' implies a read-only operation, but it says nothing about pagination, the limit cap, or what happens on an invalid/expired token.

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?

Three front-loaded sentences with no filler; the return fields and the action directive are packed efficiently. Slightly dense but every clause is doing work.

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 no output schema, enumerating the returned fields is exactly the right compensation, and the token instruction covers the only required param. The unaddressed limit parameter is the remaining gap.

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 coverage is 0% for 2 params. The description usefully explains where action_token comes from, but the limit parameter (1-20) is never mentioned, so an agent has no guidance on its meaning or 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 retrieval: products the VIA network suggests for the owner based on their Taste Card, and even enumerates the returned fields. An agent can distinguish this from get_my_taste_card (which returns the card itself) without opening either schema.

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?

Adds real usage direction — show the owner the images and links, and pass the action_token from VIA's message — which tells the agent how to act on results and where the required credential originates. It stops short of naming alternatives or stating a when-not condition.

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