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

With no annotations, the description should disclose behavioral traits. It only states the syntactic constraint (effect must be a Delay) and lists fraction options. No mention of side effects, reversibility, or impact on project state. This is insufficient for complete transparency.

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?

Very concise. The first sentence states the purpose, followed by bullet-list parameter explanations. No redundant information.

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?

Output schema exists, so return values are not needed. The description covers purpose and parameter semantics adequately but lacks behavioral transparency and usage guidelines. For a tool with 3 parameters and constrained values, it is minimally complete but has gaps.

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 0%, so description adds meaning. It explains fraction with allowed values, effect_index with the 'must be a Delay' constraint. unit_index is briefly described as 'AU index' but could be clearer. Overall, it compensates for missing schema descriptions.

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 it sets synced delay time on a Delay effect using a musical fraction. The description specifies the resource (Delay effect) and action (set synced delay time). It distinguishes from other set_* tools by targeting a specific effect type, though it does not explicitly compare to siblings.

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?

Implies usage by requiring effect_index to be a Delay and listing allowed fraction values. However, no explicit guidance on when to use this versus alternatives (e.g., unsynced delay time setup), nor prerequisites like effect existence or state.

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