Add component to case

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

With no annotations, the description carries the full burden of behavioral disclosure. It only mentions 'component name' and gives no information about side effects, whether the component must already exist, overwrite behavior, or return values. The mutation behavior is not disclosed at all.

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 under-specified rather than concisely useful. It is a fragment that does not earn its place because it repeats the title and adds only the parameter name, which is already in 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?

For a simple two-parameter tool with no output schema, the description is incomplete: it omits return value expectations, prerequisites, and relationship to sibling component tools. The agent cannot fully assess what the tool will do or when to invoke it.

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% with both parameters described ('Test case id' and 'Component name'). The description adds no extra semantic meaning beyond the schema, so baseline 3 is appropriate.

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 'TestCase.add_component: component name.' essentially restates the tool name and title without explaining what adding a component does or what a component is. It does not distinguish from sibling tools like kiwi_case_remove_component beyond the verb, which the title already conveys.

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 usage guidance is provided. The description does not mention when to use this tool versus alternatives such as kiwi_case_add_tag or kiwi_case_remove_component, nor any prerequisites like the component needing to exist.

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