This server's wallet and limits

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

With no annotations, the description carries the full burden, and it does imply a read-only status query by describing returned state rather than an action. It adds real context by scoping authorizations to 'today (UTC)', but says nothing about auth requirements, currency denomination of the limits, or whether the limits are per-transaction or rolling daily.

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 sentence with no filler; the three returned data points are the whole content and each earns its place. The UTC qualifier is placed tightly next to the thing it scopes.

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 usefully enumerates the three return fields, which is the most important compensation. However, for a wallet/limits tool an agent still cannot tell limit units or windows, or whether calling it has any side effects, so it is adequate rather than complete.

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?

Zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies.

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?

Names the specific resource (the paying wallet) and enumerates what it exposes: address, spend limits, and today's authorizations in UTC. That is enough to distinguish it from every sibling, which are all order/payment-flow tools. It loses a point only because it is a noun phrase with no verb, so the agent must infer this is a read/retrieve operation.

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 at all: it never says to call this before agoreum_place_order or agoreum_pay_order to check whether funds or limits allow the transaction, which is the obvious reason the tool exists. No exclusions or alternatives are named.

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