create_settings_main_regenerate

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

Annotations already signal non-read-only and idempotent behavior. The description adds that a new API key is produced, but it does not state that the old key is invalidated or that this is a rotation with security implications; the word 'Get' also downplays the side effect.

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?

Two short sentences, front-loaded with the purpose and including the endpoint. No wasted 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?

For a zero-parameter operation with an output schema and annotations, the description is nearly sufficient. It could mention old-key invalidation, but the core call semantics are present.

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 tool has zero parameters and the schema is fully self-describing, so no parameter documentation is required. Baseline 4 applies because the description need not compensate for any parameter gaps.

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?

States a concrete action and resource: returns main settings after generating a fresh API key and cites the POST endpoint. The verb 'Get' is slightly misleading for a regeneration operation, and the description does not explicitly differentiate from list_settings_main beyond the key-generation aspect.

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 on when to invoke this operation versus alternatives such as list_settings_main for viewing settings or create_settings_main for updating settings. The intended trigger—rotating/regenerating the API key—is only implicit in the tool name and endpoint, not in the description.

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