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

Annotations declare readOnlyHint/idempotentHint, and the description still adds real context beyond them: nothing is submitted, it is public for any address, and it fails with 404 when the address has nothing staked. That error-behavior disclosure is the kind of detail annotations cannot carry; only the response/pagination shape is left unaddressed.

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?

Front-loaded with the outcome and every clause earns its place (what it returns, no submission, when to use, alternative, error case). It is dense to the point of being a single run-on paragraph, which slightly hurts scanability.

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 one-parameter read-only estimator with an output schema and full annotation coverage, this is complete: it covers scope, safety, the failure case, and routing to the sibling. Return-value details are correctly left to the output schema.

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% and the single `requester` parameter is already documented with its TRON base58 pattern, so the schema does the heavy lifting. The description adds the useful nuance that the address need not be the caller's ("any address"), but nothing about the parameter format.

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?

States a specific verb (estimate) and resource (flash unstake), enumerates exactly what the estimate returns (total staked, fee percentage, payout, delegations to reclaim, minimum unstake amount), and explicitly separates itself from `tronsave_get_flash_unstake_request`, which checks an existing request.

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?

Gives explicit sequencing ("Use before requesting a flash unstake") and names the alternative tool with the condition that selects it (checking an existing request). An agent knows both when to call this and when to call the sibling instead.

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