get_album_tracks

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

With no annotations, the description carries the full behavioral burden. It discloses a non-obvious output trait: track objects are simplified and lack an `album` key, and it tells callers how to handle that. This goes well beyond a generic 'get' description, though it doesn't mention errors, auth, or rate limits.

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 compact and well-structured: the main action is front-loaded, and the important behavioral caveat about the simplified shape is separated into its own short paragraph. Every sentence adds value.

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?

This is a simple read tool with an output schema available, so the description doesn't need to explain return values. It covers the key non-obvious details: default behavior for `limit` and the missing `album` key in result objects. Minor gaps like explicit routing versus sibling tools prevent a perfect score.

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 0%, so the description must compensate. It adds meaningful semantics for `limit` by explaining that omitting it fetches all tracks, but it doesn't describe valid limit values or elaborate on `album_id` beyond its name and type.

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 the resource and action: retrieving an album's tracks. It also differentiates the result shape from other track-returning tools by noting the simplified track objects, so an agent can distinguish it from siblings like get_playlist_tracks or get_artist_top_tracks.

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 clear context for when to call this tool: when you need an album's tracks. The instruction to omit `limit` to fetch all tracks provides a concrete usage rule, though it doesn't explicitly name alternatives or exclusions relative to sibling tools.

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