Create Micro billing portal

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

The annotations already indicate this is a non-read-only, non-idempotent operation, and the description adds that the operation is hosted by Stripe. It does not disclose side effects, prerequisites, or external dependencies beyond the phrase 'hosted Stripe', so the added transparency is modest.

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 filler, front-loading the action and resource before the scope. Every word earns its place.

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, the description is sufficiently complete: it states what is created, the provider, and the target account. Return-value details are not required because an output schema is 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 baseline for no-parameter tools is 4. The description adds the relevant context that the session is for the authenticated account, so no parameter documentation is needed.

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 identifies the verb and resource: it creates a hosted Stripe billing-management session for the authenticated account. This is more specific than the title, but it does not explicitly distinguish this from closely named siblings such as micro_billing_checkout or micro_billing.

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 select this tool over micro_billing or micro_billing_checkout, and there are no alternative routing cues. The only contextual clue is the authenticated-account scope, which is not enough to guide agent selection.

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