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

Annotations already declare readOnlyHint, idempotentHint, non-destructive behavior, and closed-world scope, so the safety profile is covered. The description adds useful disclosure of returned data, but does not explain pagination, transaction-limit behavior, or rate/auth constraints.

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?

It is a single dense sentence that front-loads the single-address scope and then lists outputs efficiently. There is little waste, though the 'poa1...' shorthand and long field list make it slightly compact rather than fully structured.

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 annotations covering safety and no output schema, the description usefully names many returned fields. However, the tx_limit parameter remains unexplained, which is a meaningful gap for controlling the recent-transactions section.

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 0%, so the description must carry parameter meaning. It gives a format hint for the address parameter via 'poa1...', but never explains tx_limit, its default, or its effect on returned recent transactions.

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 identifies a single-address lookup and enumerates the data returned (balance, rewards, streak, invites, recent transactions), so the resource and scope are clear. It does not explicitly contrast with sibling tools such as get_transaction or get_leaderboard, keeping it below 5.

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?

It implies use when one address's profile/details are needed, but gives no explicit when-to-use guidance, prerequisites, or alternatives among the many sibling tools. The agent must infer selection from the return-field list alone.

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