fmod_Sound_setFadeInCurve

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

The description lacks details on side effects, such as whether it replaces existing fade-in curves, or permissions required. Without annotations, the description carries the full burden and fails to disclose important behavioral traits.

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 (one sentence plus a method reference), which is efficient. However, the method reference may be cryptic to some users, slightly reducing clarity.

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 is minimal and does not cover important context such as return values, prerequisites, or behavior when called multiple times. For a mutation tool with no output schema and no annotations, this is insufficient.

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 coverage is 100%, so the schema already describes all parameters adequately. The description adds no extra meaning beyond the schema, so a baseline score of 3 is appropriate.

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 (sets fade-in curve) and the target (instrument, though the tool name says Sound). It distinguishes from the sibling fmod_Sound_setFadeOutCurve by specifying fade-in. The reference to the API method adds context for developers familiar with FMOD.

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 like fmod_Sound_setFadeOutCurve. The description does not provide context about prerequisites or typical use cases.

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