TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and network scope are covered. The description adds that the result includes both metadata and the full track list, which is useful return-shape context, but says nothing about auth, rate limits, or pagination.

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

Conciseness5/5

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

A single front-loaded sentence that names the resource, the scope (full track list), and the input mechanism with zero waste.

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

Completeness4/5

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

With an output schema present, return values need not be explained, and annotations cover the read-only/open-world profile. For a one-parameter lookup tool this is essentially complete; only missing explicit sibling routing and edge-case behavior.

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

Parameters3/5

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

Schema coverage is 100% for the single url parameter and the schema already documents it as a full soundcloud.com playlist/album permalink URL. The description's 'resolved from its URL' confirms the input but adds no syntax or format detail beyond the schema, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb ('resolved from its URL') and resource ('a SoundCloud playlist or album's metadata plus its full track list'), which clearly distinguishes it from soundcloud_track, soundcloud_profile, and soundcloud_user_tracks. It is clear, though it never names the sibling tools it is distinguished from.

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

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'resolved from its URL' implies the tool is for when you already have a playlist/album permalink, which is public/implicit usage guidance. However, there is no explicit when-to-use vs. when-not, no mention of alternatives like soundcloud_search or soundcloud_user_tracks, and no prerequisites.

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