payments_create_config

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

Annotations already indicate this is a write operation (readOnlyHint=false) and not destructive or idempotent. The description simply says 'Create', which is consistent but adds no additional behavioral context such as side effects, permissions required, or response behavior. More detail would be expected for a creation tool with no output schema.

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 single sentence with no wasted words. However, it is under-specified and does not provide enough information to be genuinely helpful. It is not concise in the sense of conveying essential details efficiently; it is simply too short.

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 tool with nested parameters, required fields, and no output schema, the description does not explain what happens after creation, how to verify success, or any specific constraints. The schema covers parameter format, but the description lacks context about the broader behavior and expected outcomes.

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 input schema provides complete descriptions for all parameters (100% coverage), including nested objects for live and test configs with required apiKey and publishableKey. The description adds no parameter-specific information, but since the schema covers everything, a baseline of 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 states a clear action ('Create new provider config') and a resource, but it is vague about what specifically constitutes a 'provider config'. It does not distinguish itself from sibling tools like payments_create_integration_provider, which could be confused with this tool. It is not a tautology, but it lacks specifity to fully convey purpose.

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?

There is no guidance on when to use this tool versus alternatives. No mention of prerequisites, scenarios, or exclusions. The description does not help an agent decide between this and similar payments configuration tools.

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