TDQS

B3.1/5.0
Behavior2/5

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

Annotations already cover the safety profile (destructiveHint=false, openWorldHint=false, readOnlyHint=false), and the description adds nothing beyond them — no note on whether the change is reversible, which sequence it applies to, or whether an undo step is created. For a state-mutating tool the description carries no extra behavioral context.

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

Conciseness4/5

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

A single six-word sentence with zero waste and the action front-loaded. It is appropriately sized for a trivial toggle operation.

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 an output schema present, return values need not be described, and the annotations plus full parameter coverage supply the rest. For a simple two-parameter toggle, the description is complete enough to invoke correctly, though a note on required context (active sequence) would close the last gap.

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 coverage is 100% and both parameters are fully documented in the schema (muted as a boolean toggle, track_index as 0-based). The description's 'mute or unmute' merely echoes the boolean and says nothing about track_index, so baseline 3 applies.

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?

States a specific verb pair (mute/unmute) and resource (audio track), which is enough to distinguish it from sibling track tools like lock_track, rename_track, and toggle_track_visibility. It stops short of naming those siblings or stating the scope of the track being acted on.

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 gives no context for when to use this versus other track-state tools, nor any prerequisites (e.g., needing an active sequence or a valid track index). The two-mode behavior is expressed only via the parameter, not in prose.

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