set_track_panning

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

No annotations are provided, and the description does not disclose behavioral traits beyond the obvious mutation. It doesn't mention reversibility, permissions, or side effects. The description only states the action and parameter meanings, which are more about parameter semantics than behavior.

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 compact: one purpose sentence plus two parameter lines. No redundancy, no fluff. It's well-structured and 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?

For a simple two-parameter setter with an output schema, the description is largely complete. It explains both parameters and the action. However, it does not mention any constraints like error handling, prerequisites, or what happens with invalid track indices, which leaves some ambiguity. But given the simplicity, it's mostly sufficient.

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?

Schema description coverage is 0%, so the description must explain the parameters. It does so fully: track_index is defined as 1-based track number, and panning is given a clear range with semantic labels (full left, center, full right). This adds significant value beyond the bare schema.

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 clearly states the action: 'Set the mixer panning for a track' – a specific verb and resource. It differentiates from sibling tools like set_track_volume by naming panning specifically.

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?

No guidance on when to use this tool versus alternatives like set_track_volume or set_track_mute. It does not mention any prerequisites or exclusions, so the agent gets no context about when this tool is appropriate.

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