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

With no annotations, the description carries the burden. It discloses that only published albums are included and enumerates the fields returned (track count, page URL, embeddable player URL), which is useful. It does not mention ordering, default pagination, or any side effects, but for a read-only list tool the disclosed behavior is meaningful.

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 sentence immediately names the returned resource class and the three key output fields. There is no filler or repetition.

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?

The tool is simple, but there is no output schema and no annotations, so the description must compensate. It states return fields, but omits pagination semantics, the meaning of 'published,' and how this tool relates to nearby siblings. An agent could call it, but would be guessing about limit/offset behavior.

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% and the description does not mention limit or offset at all. An agent cannot learn from this definition what limit/offset control, whether they are required, or how pagination behaves. The description adds no parameter meaning beyond the raw type and bounds in the schema.

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 title 'List albums' provides a specific verb + resource, and the description sharpens it: only 'Published albums' are returned, with track count, page URL, and embeddable player URL. This distinguishes the tool from sibling list_entries, list_composers, and search_tracks without needing to inspect schemas.

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?

No guidance is given about when to choose list_albums over siblings such as search_tracks, list_entries, or get_entry. The description only says it returns published albums; it does not state exclusions, prerequisites, or a selection rule.

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