TDQS

A3.8/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the destructive nature is covered by structured data. The description adds that the object destroyed is an audio overlay selected by id, but gives no further behavioral context such as permanence, side effects, or permissions. It does not contradict the annotations.

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, front-loaded sentence with no filler: action first, then object, then selection method. Every word earns its place and it remains easy to parse at a glance.

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

Completeness4/5

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

With only two required parameters, full schema parameter descriptions, an output schema, and annotations covering destructive behavior, the description is nearly complete. It could name the sibling alternative or state that deletion is permanent, but the missing context is minor given the surrounding structured data.

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

Parameters3/5

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

Schema description coverage is 100%, and both id and projectId already have clear descriptions in the input schema. The description adds only the 'by id' cue, which marginally reinforces the id parameter but does not add new meaning beyond the schema.

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 uses the specific verb 'Delete' and names the target resource ('audio overlay') and the selection key ('by id'). This clearly differentiates it from siblings like add_audio_overlay and update_audio_overlay, and from other remove_* tools by resource type.

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?

Usage is implied by the verb 'Delete' but not explicitly stated. The description does not mention when to choose this tool over update_audio_overlay, add_audio_overlay, or remove_layer, nor does it provide exclusions like 'only for existing overlays.'

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