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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is fully covered without the description. The description adds one piece of real context — the account-level scoping of results — but says nothing about result volume, ordering, pagination, or truncation, which is the main unknown for a zero-parameter list operation.

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 short sentence with no filler, and the scoping qualifier sits at the end where it reads naturally. Nothing is wasted, though the brevity comes at the cost of detail noted elsewhere.

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 simple zero-parameter read tool with rich annotations and no output schema, the definition is close to sufficient. The notable gap is what the listing actually returns and whether it is bounded or paginated, which an agent calling a parameterless list endpoint would want to know.

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 tool takes zero parameters, so there is no parameter semantics to explain and the schema already closes the object with additionalProperties=false. Baseline of 4 applies since nothing is left ambiguous about inputs.

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 gives a specific verb ("List") and resource ("Script to audio jobs"), and the plural "jobs" plus "for this account" makes clear it is a collection-level read rather than the single-job lookup implied by the sibling get_script_audio_job. It does not explicitly name or contrast with any sibling, so it stops short of a 5.

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?

There is no statement of when to use this tool versus get_script_audio_job or create_script_audio_job, no prerequisites, and no exclusion criteria. The only guidance is the implicit signal carried by the verb "List".

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