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

With no annotations, the description carries the full burden. 'Inspect' plus the read-only nature of the listed fields implies a non-mutating read, and it usefully discloses that the wallet is non-custodial and that guardrails are included. However, it never states read-only behavior explicitly, nor any auth or rate-limit considerations.

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 dense sentence that front-loads the action and then lists the returned data with no filler. Every clause 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?

With no output schema, the description does the work of enumerating the return fields (address, network, guardrails, spend totals), which is adequate for a zero-argument read tool. Only the absence of usage routing and explicit read-only framing keeps it short of full completeness.

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 the baseline of 4 applies. There are no arguments whose semantics could be added, and the description correctly describes the operation as argument-free.

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 (Inspect) and resource (wallet status) and enumerates exactly what is retrieved: address, network, spending guardrails, and USDC/$APAY spent totals. This differentiates it from apay_get_balance in substance, though it never names the sibling explicitly.

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 when-to-use guidance, no mention of alternatives like apay_get_balance, and no conditions or prerequisites. Usage is only implied by the word 'Inspect' – an agent gets no help deciding between this and the balance tool.

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