design_set_mist_band

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

No annotations are provided, so the description carries the full behavioral burden. 'Configure' implies mutation, but there is no disclosure of permissions, whether omitted properties are reset or preserved, whether changes are reversible, or what the tool returns. Listing property names does not compensate for the missing behavioral context.

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 definition is a single front-loaded sentence with no filler. It is appropriately sized for a simple configuration tool, though the field list dominates the sentence and adds little beyond the schema.

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?

This is a mutation tool with seven parameters, no annotations, and no output schema. The description does not explain when to use it, what happens to existing values when properties are omitted, or what the required layerId must reference, leaving important operational context missing.

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 description coverage is 100%, so the schema already documents every parameter including ranges like 0-1 and layerCount 1-8. The description merely repeats the parameter names without adding format, default, or interaction semantics beyond what the schema provides, which meets the baseline 3 for high schema 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?

The description states a specific verb and resource: 'Configure mist band properties', followed by the property names. This is clearer than a tautology and an agent can tell it configures an existing mist band rather than adding one. However, it does not name or distinguish itself from relevant siblings such as design_add_mist or design_add_fog_layer.

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?

There is no statement of when to use this tool versus alternatives like design_add_mist, design_add_fog, or design_set_particle_style. The description also omits prerequisites such as needing an existing mist layer ID, leaving the agent to infer usage entirely.

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