TDQS

B3.4/5.0
Behavior3/5

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 agent knows this is a safe, repeatable read. The description is consistent with those annotations and adds none of the riskiest ambiguity, but it also contributes no extra behavioral context (e.g., behavior on invalid node_id, or whether speed is expressed as a ratio versus a percentage). With annotations covering the safety profile, this lands at baseline 3.

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?

A single sentence of nine words that is verb-first and front-loaded with the key facts: what is retrieved and from what. There is zero redundancy and every word earns its place.

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?

For a one-parameter getter with a full output schema and comprehensive safety annotations, the description states exactly what data the agent will receive and nothing critical is missing for invoking the call. The only minor gap is the lack of distinction from overlapping getter siblings, which is a real but small omission at this simplicity level.

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%, with node_id documented as 'Node ID of the clip.' The description adds no parameter-level meaning, but the schema fully carries that burden, so the baseline 3 applies without requiring the description to compensate.

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

Purpose4/5

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

The description uses a specific verb ('Get') and resource ('clip') and precisely states the data returned: playback speed and reverse state. This is clear and unambiguous. However, it does not explicitly differentiate from overlapping siblings such as get_clip_properties or get_qe_clip_info, which could also surface speed-related data, so it stops short of full sibling differentiation.

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

Usage Guidelines2/5

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

The description offers no guidance on when to use this tool versus alternatives. Siblings like get_clip_properties and get_qe_clip_info overlap in scope, and setter counterparts (speed_change, reverse_clip, set_clip_speed_qe) represent the write-side operations, yet no when-to-use context, exclusions, or alternative mentions appear anywhere in the description.

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