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

With no annotations, the description carries the full burden. It usefully discloses an auth requirement ('requires a bearer key') and a key behavioral trait ('the token is single use'), which is more than most. However, it says nothing about token expiry, whether the call mutates the service record's state, or whether repeated calls are idempotent.

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, front-loaded with the core action, then auth and token semantics. No filler or redundancy.

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 covers the operation, auth, and token lifecycle, which are the highest-value facts for a mutation-style tool with no annotations and no output schema. It is nonetheless incomplete for three fully undocumented parameters and leaves the effect on the underlying record unstated.

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 description coverage is 0% and the description never mentions site_id, provider_name, or provider_email. At zero coverage the description is expected to compensate for the undocumented parameters, and it does not — an agent gets no help on what to supply or how the provider fields affect the result.

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 and artifact: creates a one-time URL the service provider opens to confirm recorded work. This is clearly distinguishable from siblings like check_service_record or add_events. It stops short of explicitly naming a sibling, so it lands at 4 rather than 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?

The purpose implies when to use it (obtaining provider confirmation of recorded work), but there is no explicit when-not guidance, no prerequisites beyond the bearer key, and no routing to an alternative tool. Usage is inferred rather than stated.

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