Execute Payout (Withdrawal)

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

Although annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, the description adds useful behavioral context: crypto is debited from the sender wallet, signed_transaction is required for solana/stellar networks, and idempotency_key prevents double-spending on retries. It does not disclose authorization, quote-expiry, or rate-limit behavior, but it meaningfully supplements the annotations.

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 front-loaded with purpose and then structured with Args and Returns sections, making it easy to scan. However, the full parameter list repeats schema information that is already 100% covered, so some of the content does not fully earn its place.

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 output schema, the description usefully says it returns payout_id and status, and it explains the quote prerequisite, required sender wallet, and network-specific signing requirement. It is complete enough to call correctly, though it could mention quote-expiry or authorization constraints for a high-stakes withdrawal operation.

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%, so the schema already documents all five parameters and their meanings. The description restates the same parameters with modest added context, such as the crypto-to-PIX flow and network-specific signed-transaction requirement, but does not add enough beyond the schema to raise the baseline.

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 uses a specific verb and resource ('Execute a USDC/USDT -> PIX withdrawal') and ties it to a previously created payout quote. It clearly distinguishes this execution step from quote creation and from other payout read/list operations, so an agent can identify the tool's role without opening the schema.

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 gives clear usage context by stating that execution requires a quote from ashar_create_payout_quote and by identifying the required quote_id and sender_wallet_id. It does not explicitly say when not to use this tool versus execute_transfer or execute_payin, so it falls short of full when/when-not guidance.

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