C2.8/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only uses the verb 'Get,' implying a read-only operation, but does not mention authentication requirements, pagination behavior, return format, or any side effects. This is minimal transparency that adds little beyond the verb itself.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no wasted words, front-loading the action and resource immediately. It is efficient and easy to scan, though it is so sparse that it lacks necessary supporting detail. The conciseness itself is strong, but the under-specification prevents a perfect score.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, no annotations, and the description is just one sentence. It does not explain what the tool returns, how pagination via limit/offset works, or whose albums are returned (presumably the authenticated user). For a tool with three parameters and no schema descriptions, this description leaves too much for the agent to infer and is not complete enough for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not mention any of the three parameters (limit, offset, access_token). The schema provides only types and defaults, leaving parameter semantics entirely unexplained. With zero coverage, the description must compensate, but it does not, so an agent has to guess what 'limit' and 'offset' mean and how access_token is used.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Get user's saved albums.' It clearly identifies the operation and the resource, and the resource name 'saved albums' distinguishes it from sibling tools like get_user_saved_tracks, get_user_saved_shows, and get_user_saved_episodes. An agent can tell exactly what this tool does without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 tool versus alternatives. The description does not mention any conditions, prerequisites, or sibling tools such as get_user_saved_tracks. The only implied usage is from the tool's name itself, which does not help an agent decide between closely related saved-content tools.

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