create_dark_moody_grade

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 fails to disclose whether the grade is destructive, requires a selection, or how it interacts with current state. The single sentence 'Apply registered dark-moody DRX' gives no behavioral 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?

While extremely concise, the description is too sparse to be effective. It consists of one sentence that does not earn its place as a useful guide; important details are omitted, making it under-specified rather than appropriately concise.

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 three parameters (two required) and no annotation support, the description is grossly incomplete for correct invocation. It does not mention the output schema (which exists) or any usage context, leaving the agent without enough information to use the tool reliably.

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 input schema has three parameters with no descriptions (0% schema description coverage), and the tool description adds no explanation of what 'grade_mode', 'item_index', or 'track_index' mean or how they affect the operation. The description provides zero 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 states 'Apply registered dark-moody DRX,' which indicates a specific verb and resource. However, the term 'DRX' is unexplained and assumed domain knowledge, and it does not differentiate this tool from sibling grade-creation tools like 'create_commercial_grade' or 'create_cinematic_grade.' The purpose is somewhat clear but lacks specificity.

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 no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, context, or conditions for invoking it, leaving the agent without criteria to select it over similar grade tools.

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