list_webhook_subscriptions

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

No annotations are provided, so the description carries the full burden. It discloses the required environment variables (OURA_CLIENT_ID and OURA_CLIENT_SECRET), which is useful authentication context. However, it does not state whether the operation is read-only, whether it paginates, or what happens on auth failure, leaving meaningful behavioral traits undisclosed.

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?

Two short sentences with no filler; the purpose is front-loaded and the environment variable requirement follows cleanly. Every sentence 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 simple zero-parameter listing tool with no output schema, the description covers the core operation and the auth requirement. It is nearly complete, though it could mention pagination or return shape given the absence of an output schema.

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, so there is no per-parameter meaning to convey. The description appropriately avoids parameter detail, and the baseline for zero params is 4.

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 (List) and resource (webhook subscriptions) with clear scope ('for your application'). It is distinguishable from get_webhook_subscription (singular) and create/update/delete siblings by the plural listing verb, though it does not explicitly name them.

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?

Implies usage through the listing scope but gives no explicit when-to-use or when-not-to-use guidance relative to siblings like get_webhook_subscription or create_webhook_subscription. The agent can infer purpose but is not routed to alternatives.

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