garageband_set_project_settings

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'through the visible LCD controls', hinting at UI automation, but does not mention if the operation is destructive, requires specific permissions, or what side effects occur (e.g., overwriting existing settings). This is insufficient 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 a single sentence with no wasted words, front-loaded with the action and resource. However, it could be slightly expanded to cover parameter details without losing conciseness.

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 has 4 parameters, no schema descriptions, no output schema, and no annotations, the description is severely incomplete. It does not explain the 'max_depth' parameter, what return value to expect, or how the tool interacts with the project state. The agent lacks critical context to use this tool correctly.

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 compensate. It names three parameters (tempo, key_signature, time_signature) but does not explain valid formats or ranges (e.g., tempo as string vs number, key signature notation). The parameter 'max_depth' is completely unmentioned. This leaves the agent guessing about parameter semantics.

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 tool sets tempo, key signature, or time signature in the GarageBand project, with a specific reference to 'visible LCD controls'. This distinguishes it from sibling tools like garageband_project_settings (read) and project_setting_options (list options), which are separate concerns.

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 explicit guidance on when to use this tool versus alternatives. It does not mention when not to use it or provide context for choosing between this and other setting tools like garageband_set_smart_control or garageband_set_track. The agent must infer from the description alone.

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