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

Since no annotations are provided, the description carries full burden. It does disclose the return value semantics (-1 means none), which is helpful. However, it does not explicitly state that the operation is read-only or non-destructive, nor does it mention any constraints like track_index validity.

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, front-loaded sentence that conveys the entire purpose. Every word adds value; there is no extraneous information. It is optimally concise.

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 an output schema (which the description partially explains via the -1 semantics), the tool is simple but missing parameter documentation. For a getter with one required param, the description should include at least a brief explanation of 'track_index'. The output schema can handle return structure, but the input is not covered.

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%, meaning the JSON Schema provides no parameter descriptions. The tool description also fails to explain the single parameter 'track_index' — it does not indicate its meaning, required status, or valid range. This forces the agent to rely on the schema title 'Track Index' which is insufficient.

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 verb 'Get', the specific resource 'the index of the currently playing clip slot on a track', and the special case '-1 = none'. This distinguishes it from sibling tools like 'fire_clip' or 'get_clip_info' which involve different operations.

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 is provided on when to use this tool versus alternatives. For example, it does not mention that this is a read-only query or suggest using 'get_clip_info' for more details. The agent must infer usage from context alone.

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