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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds the enumeration of possible status_label values, which helps the agent interpret results, but it discloses nothing about ordering, pagination, or result shape beyond that.

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 front-loaded sentence with the purpose stated first. The long parenthetical status enumeration is dense but earns its place by telling the agent what values it will see; no redundant filler.

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?

With no output schema, the description partially compensates by spelling out the status_label vocabulary the tool returns. Combined with annotations covering the safety profile and the schema covering the parameter, an agent has enough to invoke it, though pagination/ordering behavior remains unspecified.

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 100%, so the single 'artist' parameter and its label-vs-artist-connection semantics are already fully documented in the schema. The description does not mention the parameter at all, so it adds no meaning beyond structured fields — the baseline 3 applies.

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?

States a specific verb+resource ('Every release in this account') and clarifies scope ('with where it has reached'), so an agent knows it returns a full release listing with status. It does not explicitly distinguish itself from siblings like list_albums or list_release_todos, leaving some ambiguity about the boundary between releases, albums, and todos.

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?

Usage is only implied: the agent can infer it should call this to enumerate releases and their statuses, and the 'including anything Audora asked about' phrase hints at a relationship with the question tools. However, no alternatives are named and there are no explicit when/when-not conditions, so the routing guidance is thin.

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