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

No annotations are provided, so the description must disclose behavior. It offers parameter constraints and allowed values but omits any details on side effects, error conditions, reversibility, or return values. Lacks the behavioral disclosure expected 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 fairly concise with a clear first sentence, followed by parameter explanations. The list of rate values is necessary but somewhat verbose; still, it is 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?

The description covers the core parameters and allowed values, but lacks guidance on usage context, error handling, and aftermath of the operation. Given the tool's simplicity and absence of annotations, it is adequate but not fully complete.

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?

All three parameters are explained beyond the schema: unit_index as AU index, effect_index with the Tidal requirement, and rate with an explicit allowed list of musical fractions. This fully compensates for the 0% schema description coverage.

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?

Clearly states the action (Set LFO rate), the target (Tidal effect), and the input type (musical fraction string). This distinguishes it from sibling tools that set other effect parameters.

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?

Provides parameter constraints (must be a Tidal) but does not explicitly state when to choose this over other effect-setting tools or mention alternatives. Usage is implied but not directed.

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