get_wallet_id

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

With no annotations, the description carries the burden, but this is a zero-parameter read, so the risk surface is small. It implies the account is authenticated and that a walletId is returned, but does not state auth prerequisites or error behavior if the account lacks a wallet.

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 front-loaded sentence with the core action first and the use case in a compact parenthetical. No wasted words.

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 trivial zero-param lookup with no output schema, the description suffices: it says what it fetches and why. Minor gap is that the return shape (a bare ID string) is only implied.

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 takes no parameters, so the schema has no semantics to convey. The baseline of 4 applies; the description correctly frames the tool as self-contained on the authenticated account.

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?

Names a specific verb and resource: it retrieves the walletId of the authenticated Asaas account. This is clearly distinguishable from sibling tools like get_account_status or get_pix_status. Lacks only explicit sibling differentiation.

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 parenthetical states the concrete purpose: it is needed to configure Split payouts. This gives the agent a clear context for when to call it, though it offers no exclusions or alternatives.

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