update_applicant_group

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only mentions the return value ('Updated applicant group details') and does not explain whether the update is partial or full, any side effects, permissions required, or how the update behaves with the provided group_data. This is minimal transparency for a mutation tool.

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 a compact docstring with a clear structure: action, args, and returns. It is concise, front-loaded, and uses no unnecessary words, making it easy to parse quickly.

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?

Despite the presence of an output schema, the description is too thin for a tool with no annotations. It does not explain what an applicant group is, the semantics of group_data, or when to use this tool. The description leaves significant gaps in context that would help an agent use it correctly.

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?

The schema provides only parameter types with 0% description coverage, so the description must compensate. It does add basic meanings: group_id is 'The applicant group ID' and group_data is 'Updated group data dictionary.' However, the group_data description is vague and does not specify accepted keys or structure, only partially compensating for the schema's lack of detail.

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 and target: 'Update an applicant group.' This distinguishes it from sibling tools such as update_applicant and update_application by explicitly naming the group entity.

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 explain when to use this tool over alternatives, nor does it mention any prerequisites, exclusions, or contextual conditions. The agent must infer usage solely from the tool name and minimal description.

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