Get full account balances overview

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds useful non-obvious context: the endpoint's Weight (1) rate-limit cost and the exact account dimensions returned. It stops short of describing pagination, freshness, or auth requirements.

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?

Short and front-loaded, with the resource stated first and the return-content detail second. Minor redundancy: the title is repeated verbatim as the first line of the description, and the 'Weight: 1' note is appended without framing.

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?

There is no output schema, so the description carries the burden of describing returns — and it does so adequately, naming the Spot/Futures dimensions, per-coin price data, and USDT/BTC total valuations. For a no-required-parameter read tool this is sufficiently complete, though it omits zero-balance behavior and currency precision.

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% for the two optional language params (appLang/sysLang), so the schema already documents their meaning and precedence. The description adds nothing about parameters, which is the expected baseline when the schema does the heavy lifting.

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?

Specific verb ('Get') plus resource ('full account balances overview') with scope detail: Spot (Bot Account) and Futures (Trader Account) dimensions, per-coin prices, and USDT/BTC totals. It does not explicitly contrast with the sibling pionex_account_get_balance, so it earns a 4 rather than 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?

No when-to-use guidance, prerequisites, or alternatives are stated. The sibling pionex_account_get_balance is a natural alternative that the description never acknowledges, leaving the agent to infer which balance endpoint to call.

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