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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds the underlying endpoint (Bookeo: GET /payments/{id}) and the returned fields, but says nothing about auth, error behavior for an invalid id, or rate limits. Modest value beyond annotations.

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 compact sentences with zero waste; the core purpose and returned fields are front-loaded before the endpoint reference.

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?

With no output schema, the enumerated returned fields give the agent a sense of the response shape, which is genuinely useful for a single-entity fetch. Some detail (what happens on unknown id, response envelope) is absent, but the definition is adequate for a simple read tool.

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?

Only one parameter (id) with 100% schema coverage, so the schema already documents it fully. The description adds no format, example, or sourcing detail for the id beyond what the schema provides — baseline 3.

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 (one payment), and enumerates the fields returned (amount, method, reason, received time, customer, gateway transaction id). The singular 'one payment' implicitly distinguishes it from the sibling list tools bookeo_list_payments and bookeo_list_booking_payments, though it never names 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?

No guidance on when to use this versus bookeo_list_payments or bookeo_list_booking_payments, and no stated prerequisites. The agent must infer that a known payment id is required.

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