addToParentalControlCategories

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

No annotations are provided. The description's safety note adds behavioral context by warning against production use, implying potential harm or unintended consequences. However, it does not disclose other important traits like irreversibility, required permissions, or side effects beyond the note.

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 concise with two sentences: the first clearly states the purpose, and the second provides a critical safety warning. It is front-loaded and contains no unnecessary words.

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?

The tool has two required parameters and no output schema. The description is minimal but sufficient for a simple add operation. However, given the safety warning, more context on verification or rollback might be helpful, but not strictly required.

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 ('Profile ID (6-character alphanumeric identifier)' and 'Domain name or identifier to add'). The description adds no additional meaning beyond what is in 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 clearly states the tool's action: 'Adds a category to the parental control blocklist.' It specifies the resource (parental control blocklist) and the action (adds), distinguishing it from similar tools like 'addToParentalControlServices' or 'removeFromParentalControlCategories'.

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 safety note 'Only use with designated test profiles' provides a clear restriction on when not to use the tool (production profiles), but does not offer explicit guidance on when to use it or alternatives. The context implies it is for testing, but usage context is not fully elaborated.

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