List Test Tenants

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

Annotations already cover the read-only, idempotent, non-destructive profile, and the description adds useful context: it is an ADMIN operation and returns sandbox_tenants with API key prefixes. It does not discuss pagination or whether API key prefixes are masked, but it adds meaningful behavioral detail beyond the annotations.

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 short, front-loaded, and wastes no space. It states the resource, admin restriction, lack of arguments, and return content in three efficient sentences.

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-argument read-only list tool with rich annotations, the description provides the key missing context: the admin requirement and the shape of the returned items. No output schema exists, so the return summary is especially useful.

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?

There are no parameters, so the baseline is 4. The description explicitly confirms 'No arguments,' which aligns with the empty input schema.

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 gives a clear verb and resource: list all provisioned sandbox tenants. It is easy to distinguish from general wallet/customer listing tools, but it does not explicitly differentiate itself from related siblings such as provision_test_tenant or get_tenant_credentials.

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?

It states 'ADMIN operation,' which gives an important prerequisite, but it does not explain when to use this versus related tenant tools like provision_test_tenant or get_tenant_credentials. The usage is implied by the name and description rather than explicitly guided.

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