v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior, but it only offers cryptic hints: it says 'unlock' and 'bypass' without explaining side effects, prerequisites, idempotency, or what actually happens when invoked. This is not enough for an agent to anticipate the tool's real-world impact.
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, but the brevity is the result of under-specification rather than effective conciseness. It is a fragment with a slash-separated condition and no sentence structure, making it harder to parse rather than easier.
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 is inadequate for a tool with no annotations and no output schema. Key terms ('MPP', 'local bypass'), the role of sku, the meaning of 'prepaid unlock', and the relationship to the sibling tools are all left unexplained.
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, sku, has no schema description and is never mentioned in the tool description. With schema description coverage at 0%, the description was expected to clarify how to populate sku, but it provides nothing whatsoever.
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 hints at an unlock action for an 'agent prepaid' state, but it is phrased as a fragment ('Agent prepaid unlock when MPP enabled / local bypass') rather than a clear statement of what the tool does. The terms 'MPP' and 'local bypass' are undefined, and the description does not distinguish this tool from the billing-related siblings like billing_checkout or billing_portal.
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 phrase 'when MPP enabled / local bypass' suggests some conditional context, but it is not explained and no alternatives are mentioned. There is no guidance about when to choose this tool over the sibling billing tools or how to handle the two listed conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
