ActivateSubscription

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

No annotations provided, so the description carries full burden. It does not disclose side effects, idempotency, required permissions, or what happens if subscription is already active.

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?

Very concise at one sentence with no unnecessary words. However, it could benefit from more structure (e.g., listing effects).

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?

Given the complexity (activation with a generic body parameter) and no output schema, the description is incomplete. It does not explain the body's required fields, return values, or prerequisites.

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 only parameter 'body' is an object with description 'Request body', which is vague. The tool description adds no meaning beyond the schema; baseline for 100% coverage is 3, but the poor parameter description reduces it.

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 states 'Activate a subscription to the orders', but it is ambiguous what 'orders' refers to. It distinguishes from siblings like DeactivateSubscription by verb, but does not clarify if it activates an existing subscription or creates a new one.

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?

No guidance on when to use this tool vs alternatives like CreateSubscription or DeactivateSubscription. No prerequisites or exclusions mentioned.

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