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

With no annotations provided, the description carries the burden of behavioral disclosure. It adds the authentication requirement and indicates the resource is 'current', but does not mention read-only nature, response format, or any rate limits. The description adds some context beyond a bare get, but not rich detail.

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?

The description is a single concise sentence front-loading the primary purpose ('Get your current TRX balance and deposit information') followed by a short authentication note. Every word earns its place, and there is no verbosity.

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?

For a simple no-parameter get tool with no output schema, the description covers the essential purpose and a key requirement (API key). It could be slightly more complete by hinting at return structure or distinguishing from get_deposit_info, but given the low complexity, it is largely sufficient.

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 has zero parameters, so the schema is trivially complete. With no params to document, the baseline is 4, and the description does not need to add parameter details. It appropriately omits any param-related content.

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 clearly states the tool retrieves 'current TRX balance and deposit information', which is a specific verb and resource. However, it doesn't explicitly distinguish itself from the sibling get_deposit_info, which could cause ambiguity about which to use.

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 description mentions 'Requires API key authentication', which is a prerequisite, but provides no guidance on when to use this tool versus siblings like get_deposit_info or get_earnings. No explicit when-to-use or alternatives are given.

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