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

Annotations declare readOnlyHint=true and openWorldHint=true, so the safety profile is already covered. The description goes beyond that by disclosing the returned payload (balances, positions, registration status, next steps), which is meaningful since no output schema exists. It stops short of noting rate limits, whether it fails for unregistered wallets, or freshness of the data.

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 that enumerates the payload with no filler or redundancy. It is efficiently sized for a one-parameter read tool, though the list-style phrasing is slightly dense.

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 correctly carries the burden of describing return content and does so thoroughly for a simple read-only, single-parameter tool. Gaps are minor: no failure modes for invalid/unregistered wallets and no note on data freshness.

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?

Schema description coverage is 100%: the single 'wallet' parameter is documented with its format pattern. The description adds nothing about the parameter, so the baseline 3 applies — the schema does the work and the description neither helps nor hurts.

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 the specific resource (a wallet) and enumerates exactly what is returned: test ETH/gas balance, tUSDC balance, open positions in this week's market, registration status, and next-step hints. That is concrete and distinctive, though it never states the verb explicitly and does not call out how it differs from siblings like get_leaderboard or get_registration_message.

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?

The mention of 'registration status' and 'suggested next steps' implies this is a status/entry-point call in the onboarding flow, which is useful implied usage. But there is no explicit when-to-use statement, no prerequisite (e.g., call before register_agent or build_order), and no exclusion relative to the seven sibling tools.

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