install_to_user_dir

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 states the tool copies default sound files to the config directory for modification, but lacks details on whether files are overwritten, directory creation, or error conditions. This provides basic but incomplete 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.

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

The description is concise, uses bullet points for clarity, and front-loads the core action in the first line. Every sentence adds value with no wasted words.

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 zero-parameter tool with an output schema, the description adequately covers purpose and usage scenarios. It does not elaborate on return values (not required due to output schema) or side effects like overwriting, but the simplicity of the tool makes this likely 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?

The input schema has zero parameters, making schema coverage trivially 100%. Per the rubric, a baseline of 4 applies. No parameter information is needed, and the description does not need to add any.

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 primary action: 'Install sound files to user's config directory.' This is a specific verb-resource combination that distinguishes it from sibling tools list_available_sounds and play_sound, which are read and playback operations respectively.

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 includes explicit 'WHEN TO USE THIS TOOL' bullets, covering customization, first-time setup, and troubleshooting. While it does not specify when not to use or explicitly name alternatives, the use cases are clear and distinct from siblings.

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