fred_category_children

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

No annotations are provided, so the description must fully disclose behavioral traits. It states the return format but fails to mention whether the operation is read-only, what happens if no children exist, pagination behavior, or any rate limits. The lack of these details reduces 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?

The description consists of two short sentences, with the purpose front-loaded. Every sentence provides necessary information without redundancy. It is appropriately sized for a simple tool.

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 three parameters with no descriptions and the sibling tools with similar names, the description is incomplete. It does not explain parameter usage, error states, or edge cases. While an output schema exists, the lack of parameter documentation leaves significant gaps for the agent.

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 0%, so the description should explain the parameters. It only mentions 'category_id' implicitly via the tool name, and does not explain 'realtime_start' or 'realtime_end' at all. The description adds no meaning beyond the raw schema, leaving the agent uninformed about optional date filtering.

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 action ('Get') and the resource ('child categories for a FRED category'). The verb and noun are specific and differentiate it from sibling tools like fred_category (gets a single category) and fred_category_related (gets related categories).

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. It does not mention when to avoid it, prerequisites, or compare it to sibling tools such as fred_category or fred_category_series. The agent is left to infer usage from the tool name alone.

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