update_widget_parameter_mappings

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

The description only states 'Update', which implies mutation but does not disclose details like merge vs replace behavior, potential side effects, or required permissions. With no annotations, the description should provide more context, but it falls short.

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), but it lacks explanatory detail for a tool with a non-trivial schema. It could be more informative without being verbose, so it scores average.

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 complexity of the parameter mappings (array of objects with various fields) and the lack of an output schema, the description is insufficient for an agent to fully understand the tool's behavior, such as how mappings are merged or what happens when both 'parameterMappings' and 'removeParameterNames' are provided.

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 baseline is 3. The description adds no additional meaning beyond the schema; it does not explain the merge/replace logic or the role of 'removeParameterNames'. The agent must rely solely on parameter descriptions in 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 explicitly states 'Update a widget's parameter mappings', clearly indicating the action and resource. This distinguishes it from sibling tools like 'update_widget' (which updates general widget properties) and 'get_widget_parameter_mappings' (read-only).

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 guidance is provided on when to use this tool versus alternatives, such as 'update_widget' or direct parameter mapping modifications. There are no prerequisites or exclusions mentioned, leaving the agent to infer context from the name alone.

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