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

No annotations are provided, so the description carries full burden. It only states the basic operation (enable/disable) without disclosing side effects, whether changes are immediate, or if it affects playback. The description is too minimal for a mutation tool.

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 very concise: a single sentence plus parameter definitions. It front-loads the main purpose and presents parameters clearly. Every sentence adds value without redundancy.

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?

Given the tool's simplicity (3 required parameters, no enums, has output schema), the description is sufficiently complete. It covers the core operation and parameter roles. However, missing output schema details prevent full completeness, but the output schema likely handles that.

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?

Despite 0% schema description coverage, the description explains each parameter: sample_index (0-based pad index), enabled (boolean), and unit_index (integer, -1 for auto-detect). This adds meaning beyond the schema's titles, though it lacks details like value ranges or behavior of unit_index.

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 (Enable/disable) and resource (drum pad on Playfield drum machine). It also briefly explains the parameters, making the purpose unambiguous. The name aligns with the description and distinguishes it from other set_* tools.

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 copy_playfield_sample or list_playfield_samples. The description lacks context for selection, such as prerequisites or when to prefer one tool over another.

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