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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds that the listing is a per-item "one-line summary" grouped into two classes, which is genuine context beyond the annotations. It stops short of saying anything about ordering, result count, or whether the list is static.

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 the verb and resource first, followed by the return-shape clause. It is well within budget, though the marketing-flavored phrasing ("that run instantly", "you can send") is slightly less precise than a plain statement of the two categories would be.

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?

No output schema exists, so the description carries the burden of hinting at return values, and it does so by noting the one-line summary and the two categories. For a zero-parameter, read-only listing tool with full annotation coverage, that is close to sufficient; only the sibling routing guidance 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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a no-parameter tool applies. Nothing in the description misleads about inputs, and it correctly implies the tool is unfiltered and takes no arguments.

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?

The description pairs a specific verb ("List") with a specific resource ("Goodstanding's services") and adds a scope note that it returns one-line summaries. It loses a point because it calls them "services" while the tool name says "propositions", leaving the agent to infer these are the same objects, and it never distinguishes itself from describe_proposition.

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?

There is no explicit statement of when to use this tool versus describe_proposition or submit_request. The phrases "lookups that run instantly" and "requirements you can send" vaguely gesture at the sibling capabilities, but the agent must reverse-engineer that mapping rather than being told "call this first to discover, then use describe_proposition for detail".

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