renew_webhook_subscription

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

No annotations are provided, so the description must carry the behavioral load. It usefully discloses that OURA_CLIENT_ID and OURA_CLIENT_SECRET environment variables are required, which is important auth context. It does not state whether this is a write operation with side effects, idempotency behavior, or what happens on success/failure.

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?

Three short sentences, no waste, and the core action is front-loaded. The second sentence justifies the operation and the third adds the auth requirement efficiently.

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 simple one-parameter mutation with no output schema, the description covers purpose, trigger, and auth setup. However, because there are no annotations, it should ideally disclose more about side effects, permissions, or error conditions to be fully self-contained.

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?

Schema coverage is 100% and the single parameter (id) is fully documented as 'The webhook subscription ID'. The description adds no further parameter meaning beyond the schema, so the 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?

States a specific verb (renew) and resource (webhook subscription), and explains the effect (extend expiration time). This distinguishes it from the sibling update_webhook_subscription, which changes settings rather than expiration. The purpose is unambiguous.

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 gives the trigger condition: webhook subscriptions expire and need renewal. However, it does not explicitly say when to choose this over update_webhook_subscription or what conditions would make renewal inappropriate. Usage is implied but not fully guided.

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