track_set_pan

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

No annotations are provided, so the description must cover behavioral traits. It only states the operation and range, omitting details such as whether out-of-range values are clamped, what happens if the track does not exist, or any side effects. For a mutation tool, this is insufficient.

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?

The description is a single sentence that conveys the core action and constraint concisely. There is no redundant information, and it is front-loaded.

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?

Despite having only 2 required parameters and no output schema, the description lacks important context such as error handling (e.g., invalid track_index), return values, or prerequisites. It is too minimal to fully support correct invocation.

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 description adds meaning to the pan parameter by specifying the valid range, which is helpful. However, it does not describe track_index (e.g., 0-based or 1-based, required) and with 0% schema description coverage, the description partially compensates but leaves gaps.

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 explicitly states the action (set pan) and the resource (track). It also provides the valid range (-1.0 to 1.0), which clearly distinguishes it from sibling tools like track_set_volume_db or track_set_mute.

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?

The description implies usage for adjusting stereo balance but does not provide explicit guidance on when to use this tool versus alternatives like modifying track volume. No when-not-to-use or preconditions are mentioned.

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