Renew test database

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

With no annotations to provide safety or side-effect info, the description carries the full burden. It mentions renewing a lease but does not explain any side effects, permissions, costs, or what happens to the existing lease (e.g., whether it replaces or extends). Minimal transparency.

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, concise sentence with no redundancy. It is appropriately sized for a simple action, though it could be slightly more informative without losing brevity.

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?

The description covers the core action and a timing hint but omits parameter explanations and any output details. Without an output schema or additional context, an agent may be unsure about the effects and required inputs.

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 has no descriptions for lease_id or ttl_minutes, and the description does not mention them at all. With 0% schema coverage, the description must compensate but fails to provide any parameter meaning.

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 action (renew) and the resource (an isolated real test environment lease), making it unambiguous. It also includes a timing condition ('before it expires') which reinforces the 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?

It implies when to use it (when a lease is about to expire) but does not explicitly compare with alternatives like acquire_test_database or release_test_database. The condition is present but lacks explicit differentiation.

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