Behavior2/5

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

The description provides minimal behavioral detail. It does not mention side effects such as overwriting existing sounds, name conflicts, or required project state. With no annotations, the description carries the full burden and it falls short.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that front-loads the action and resource. It is concise and contains no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations, no output schema, and only 50% parameter coverage, the description is too brief. It does not address necessary parameters like 'name' and 'dataFormat', nor does it state any prerequisites or behavioral notes needed for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds little to the schema. It clarifies that the sound comes from a disk file, but does not explain the 'name' or 'dataFormat' parameters, which lack schema descriptions. Since schema coverage is only 50%, the description should compensate but does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (add), the resource (sound), and the destination (sprite or stage), and specifies the source (audio file on disk). This distinguishes it from siblings like add_costume and remove_sound.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives like add_costume or remove_sound. The context implies it is for adding audio files, but there are no exclusions or alternative routing.

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