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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only that the return is a user-facing link, and says nothing about behavior for unrecognized task values or whether the URL is stable/authenticated. Adequate but thin against the lower annotation bar.

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?

One sentence, front-loaded with the verb and resource, with zero filler. Every clause earns its place by naming the output and its intended use.

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 one-parameter read-only lookup with no output schema, the description covers what the tool returns and why. It could have noted the URL format or behavior on invalid task values, but nothing essential for correct invocation is missing.

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 coverage is 100% with a single enum parameter whose 21 values are self-describing, so the baseline of 3 applies. The description adds no syntax, default, or selection guidance beyond 'a specific audio task.'

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 and resource: 'Return the StemConsole page URL for a specific audio task.' An agent can tell this is a URL-lookup helper rather than an audio-processing tool. It does not name or contrast with any sibling (e.g., get_split, get_capabilities), so it falls short of the top score.

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?

'so you can hand the user a direct link' implies the use case (surfacing a shareable link to the user), which is useful but implicit. There is no statement of when not to use it, no prerequisites, and no reference to alternative tools for retrieving task info.

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