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

No annotations are supplied, so the description carries the full burden of behavioral disclosure and largely drops it. It never states that this is a read-only query, what the returned row structure looks like, what happens on no matches, or how the 2-10 value cap affects results; 'in the order given' is the only behavioral detail offered.

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?

The definition is one short sentence with no padding, so it is not verbose. But it is structurally awkward: a headless relative clause with nested quotes instead of a leading verb, so the core action is buried rather than front-loaded.

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 two undocumented parameters, no annotations, and no output schema, the description is the only source of meaning and it explains neither inputs nor returns. For a tool whose name promises comparison but whose description describes filtering, an agent lacks enough to call it confidently or know what comes back.

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 neither parameter has a description, so the description must compensate and only partly does. It implies that 'values' correspond to matches on 'column' and that the order of supplied values drives output order, but it says nothing about the 2-10 item bounds, duplicate handling, or what column names are valid.

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 names the resource (TelescopeCompareHQ dataset rows) and the selection rule (column matches any of the given values), which lets an agent infer a filtered-row retrieval. However, it is a sentence fragment with no verb, and the stated behavior (returning rows that match values) reads as a filter rather than the 'Compare rows side by side / X vs Y' comparison implied by the name and title.

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 trailing phrase 'for "X vs Y" questions' is an implicit use-case cue, giving the agent some sense of when to reach for this rather than plain retrieval. There is no explicit when-not guidance and no named alternative among siblings such as dataset_search or dataset_row, so routing still requires guessing.

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