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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real context beyond that: ordering (newest first), the enumerated status values a caller will encounter, and a privacy guarantee that personal address/name/details are never returned.

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 that opens with the core action and then layers ordering, returned fields, and privacy in one pass. Dense but every clause carries information; the long status parenthetical is the only mildly bulky part.

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?

There is no output schema, so spelling out what each record contains (id, status, parts checked, dates, result page) is exactly the missing context an agent needs. Combined with annotations covering safety, the definition is nearly self-sufficient; only the relationship to get_id_check is left implicit.

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 100% and the sole 'limit' parameter is already documented as 'How many to return, newest first (default 25)'. The description's 'newest first' merely echoes the schema, adding no new syntax or default information.

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 resource ('List the account's ID checks') and even declares the ordering, which separates it from the singular get_id_check. It stops short of naming that sibling explicitly, so an agent must infer the list-vs-get distinction from the names alone.

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 listing scope ('the account's ID checks, newest first') implies usage for browsing recent checks, but there is no explicit when-to-use or when-to-use-instead-of guidance relative to get_id_check, list_request_entries or get_id_check. 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.
