Get similar bands

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 genuinely useful behavior (results are user-voted and sorted by vote count, i.e. a popularity proxy rather than similarity algorithm), but says nothing about pagination, limit interaction, or what happens for a band with no votes.

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 clipped sentence with zero filler, and the most decision-relevant fact (ordering by vote count) is front-loaded. It is efficient, though the verbless fragment form leaves no room for structural cues such as required-input notes.

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?

For a two-parameter read-only lookup with full schema coverage and no output schema, the description conveys what is returned and how it is ordered. The main omission is pagination/limit behavior, which is minor for a tool capped at 200 results.

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%, so band_id's origin (from search_bands) and limit's bounds/default are already documented in the schema. The description adds no additional parameter meaning, so the baseline of 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 names a specific resource (similar artists) and its ordering semantics (match score / vote count), which clearly distinguishes it from generic siblings like get_band or get_discography. It stops short of explicitly tying the output to the input band_id, but the resource is unambiguous.

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 guidance on when to use this versus alternatives such as get_artist or search_bands, nor any note that a band_id must first be obtained. Usage context must be inferred entirely from the name and schema.

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