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

No annotations exist, so the description carries the burden. It does disclose the dataset's contents and that the filter is optional, and the CC BY 4.0 note signals a static read-only dataset. However it says nothing about pagination, result size, or completeness of coverage across consoles.

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 front-loaded sentence defines the resource and its returned fields, followed by the filter hint and license. Nearly every clause earns its place; the CC BY 4.0 line is useful attribution rather than padding.

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, the description compensates by naming the three things it returns (modification, video output, cable chain). For a one-optional-parameter read tool with no annotations, that plus the filter semantics is close to sufficient.

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% ('Substring of a console name; omit for all'), so the schema already documents the single parameter. The description's example ('Genesis') adds a mild concreteness value but no syntax beyond what the schema states; baseline 3 applies.

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 states the resource concretely: how each retro console in the collection reaches a Sony professional monitor, enumerating the returned aspects (modification, video output, cable chain). It is clearly a read of a dataset, and the subject matter implicitly separates it from sony_monitor_specs, but no sibling is named explicitly.

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?

Usage is only implied: the optional console filter with an example ('Genesis') tells the agent how to narrow results, but there is no statement of when to call this over sony_monitor_specs or bkm_cards, nor any exclusion. Adequate but leaves routing to inference.

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