set_loop

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

No annotations are provided, so the description must convey behavioral traits. It states the basic action but does not disclose side effects, required permissions, error conditions, or impact on playback or other loop settings. For a simple toggle, this is minimally adequate.

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 short at one sentence, with no wasted words. However, it redundantly lists parameter info already in the schema. For such a simple tool, brevity is a strength.

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's simplicity (single boolean parameter), the description is somewhat complete. However, it lacks context on return values, error cases, and dependencies on other loop settings. Without annotations, more detail would be helpful for full completeness.

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 schema has 100% parameter coverage but 0% description coverage. The description adds only 'enabled (bool),' which restates the schema type without explaining the semantic meaning (e.g., true enables the loop, false disables it). This adds minimal value beyond the schema.

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 'Enable or disable the arrangement loop,' which accurately names the verb (enable/disable) and the resource (arrangement loop). This distinguishes it from siblings like set_loop_start or set_loop_length that modify loop boundaries rather than the loop's active state.

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 provides a clear functional statement but offers no guidance on when to use this tool versus alternatives (e.g., set_loop_start, set_loop_length) or when not to use it. Usage context is implied but not explicit.

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