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

Annotations already establish readOnlyHint, non-destructive and closed-world, so the safety profile is covered. The description adds value by disclosing the payload contents, which matters because there is no output schema, but it says nothing about freshness, what happens when no wallet is connected, or whether pending session requests are reflected.

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 compact clause listing the three returned facets, with the owning resource front-loaded. Nothing is wasted, though the sentence is a sentence fragment and could open with a verb to signal that it retrieves rather than configures.

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 and no parameters, the description is the only place to learn what comes back, and it only names three categories without structure, value shapes, or the relationship to the sibling session tools. Adequate to recognise the tool, insufficient to know exactly what calling it yields.

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 no parameter semantics to explain and the baseline of 4 applies. The description correctly implies the wallet scope is implicit from the connection rather than passed in.

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 names a specific resource (agent permissions on the connected wallet) and enumerates three concrete contents: agent authorisations, unattended trading session state, and daily limits. It is a noun phrase rather than a verb, so the read intent comes only from context and annotations, and it does not distinguish itself from session_request_status, which also deals with session state.

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 indication of when an agent should call this versus request_session or session_request_status. The likely precondition (a wallet must be connected, and this is a pre-trade safety check) is left entirely to inference.

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