Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
readOnlyHint=true already declares this is a safe read, and 'Get the ... URL' is consistent with that. The description adds only that the URL is a Stripe checkout URL for one repair; it does not disclose whether a checkout session is created on the Stripe side, any auth requirements, or expiration behavior of the URL.
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?
A single front-loaded sentence with no filler; the resource and scope appear immediately.
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 one-parameter read tool with annotations and no output schema, the description covers the essentials. It is slightly thin on prerequisites and on what the returned URL is intended for, but nothing critical for invoking it is missing.
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 0%, so the description must carry the parameter burden. It implies product_id identifies a ReadyKit repair product, and the schema's enum supplies the three valid values, but the description does not explain the mapping between 'product_id' and a repair beyond the phrase 'one ReadyKit repair'.
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 (get) and resource (Stripe checkout URL) scoped to a single ReadyKit repair, which is clearly distinct from the diagnose_* and repair_* siblings. It does not explicitly name an alternative or state its relationship to those siblings, keeping it just below a 5.
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?
Usage is only implied: an agent can infer this is the step after choosing a repair product. There is no explicit when-to-use, no prerequisite (e.g., must a repair exist first), and no stated alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
