get_statement

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

With no annotations provided, the description carries the burden and does volunteer 'Read-only,' which usefully discloses the non-mutating nature. However it says nothing about permissions, error behavior for a missing ID, or what 'full details' actually contains, so the behavioral picture is only partial.

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 short sentences with zero filler; the retrieval scope is front-loaded and the safety trait ('Read-only') is placed as a compact trailing qualifier.

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-only lookup with no output schema, the description supplies the essentials: what is returned ('full details'), the lookup key (ID), and the fact that it does not mutate. It stops short of characterizing the returned payload, which is a minor gap given the tool's simplicity.

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 100% and the single 'id' parameter is documented as 'Statement ID' in the schema, so the description can only add marginal value. Its phrase 'by ID' confirms the identifier is the statement's own ID rather than a related entity, but adds no format or constraint detail.

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+resource ('Get full details of a single customer statement by ID'), which distinguishes it from the sibling search_statements, delete_statement, and send_statement. It never names an alternative explicitly, but the 'single ... by ID' scoping makes the retrieval-by-identifier intent unmistakable.

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 'use this when you already have a statement ID and want its details,' versus search_statements when you don't. There is no explicit when-to-use, no prerequisite, and no named alternative.

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