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

Annotations already disclose readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only that the result includes ids, which is a minor behavioral detail; it does not describe pagination, ordering, or response fields, but for a zero-parameter read-only list operation this is acceptable.

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 short sentence that front-loads the action and resource with no filler. Every word adds information ('com ids' is a useful output hint).

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 parameters, read-only annotations, and no output schema, the description is nearly sufficient: it tells the agent exactly what the call returns (user accounts with ids). It could be slightly more complete by naming the alternative detailed-account tool or noting response fields, but nothing needed to invoke safely is missing.

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 and the schema is empty, so there are no parameter semantics for the description to clarify. Baseline 4 applies because the agent cannot err in supplying arguments.

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 states a specific verb ('Lista' / lists), a specific resource ('contas do usuário' / user's accounts), and a concrete output detail ('com ids'). This clearly distinguishes it from the many sibling list_* tools such as list_transactions or list_credit_cards, since accounts are a distinct resource.

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 guidance is given on when to prefer this tool over alternatives like organizze_get_account_context, organizze_get_balances, or organizze_create_account. The description only states what it does, leaving the selection decision to inference.

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