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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the scoping trait that the operation targets the authenticated participant's canonical account, but it does not disclose other behavioral details such as error conditions or whether the account must exist first.

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?

The description is one short sentence with no filler, front-loading the action and then specifying the resource. Every word earns its place.

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?

Given zero parameters, read-only annotations, and no output schema, the description identifies the target resource clearly enough for an agent to call the tool. The only minor gap is that it does not describe the shape or contents of the returned canonical exchange account, but the tool name and description convey the essential purpose.

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?

This tool has no parameters, so the schema fully documents everything an agent needs about inputs. The description reinforces the scope of the returned object but carries no parameter burden. A baseline of 4 is appropriate for a parameterless tool.

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 uses a specific verb ('Inspect') and names a concrete resource ('the authenticated participant's canonical exchange account'), so an agent understands what object this tool returns. It does not explicitly contrast itself with siblings like get_wallet or get_balance, but the phrase 'canonical exchange account' helps distinguish it from nearby getters.

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 is provided about when to use this tool versus siblings such as get_balance, get_wallet, or get_participant_registration_requirements. The description implies the usage context ('authenticated participant') but offers no exclusion criteria or alternative routing.

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