album_track_explorer

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

With no annotations present, the description carries the behavioral disclosure burden. It usefully discloses the operation's cost: 'Quota: one album fetch + one paginated discography walk.' It also conveys read-only intent through 'track listing' and 'spot,' though it never explicitly says no changes are made to the user's library.

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 description is two focused sentences, front-loading the tool's primary action and outcome, then adding the quota warning. There is no filler, repetition of the tool name, or unnecessary detail.

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 read-only explorer with three parameters and no annotations, the description supplies the essential context: what it returns, its differentiating use case, and its quota cost. The main gap is the unclarified max_results parameter, but a correct invocation is still achievable from the schema and description together.

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?

The description adds no parameter-level meaning beyond the schema. Album_id and response_format are documented in the schema, but max_results is not described anywhere, and the description's 'full track listing' wording does not clarify how max_results interacts with the album tracks versus the paginated discography walk.

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 clearly states a specific resource and function: 'Full track listing for one album with per-track cross-album duplicate counts.' The added phrase 'spot which songs are unique to this release vs recycled across the discography' differentiates it from simpler album-listing tools like get_album_tracks and from album stats tools like album_track_stats.

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 description gives a concrete use case: identifying which tracks on an album are unique versus reused elsewhere in the discography. It does not explicitly name sibling alternatives or state when not to use this tool, so it stops short of a 5, but the scenario is clear enough to guide selection.

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