simulate_transfer_deposit

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

With no annotations, the description carries the full burden and discloses important behavior: sandbox-only execution, production failure, and that the call causes a transfer to progress to payout without an actual on-chain payment. It does not mention idempotency, side effects on other objects, or response behavior, but the core behavioral constraints are present.

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?

Two short sentences, front-loaded with the most critical constraint ('SANDBOX ONLY'), and every clause adds useful information without repetition.

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 single-parameter sandbox simulation with no output schema, the description supplies the essential operational constraint and the intended effect. It could be stronger by noting the expected return or error semantics, but it is sufficient for correct invocation.

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 sole parameter, transferId, is fully documented in the schema ('The transfer awaiting funds'), so the baseline is 3. The description does not add additional format, constraint, or selection guidance beyond what the schema already says.

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 ('Simulate') and resource ('transfer deposit'), and explains the effect: progressing an off-ramp transfer to payout without an on-chain payment. It does not distinguish this tool from the similar sibling 'simulate_route_deposit', so an agent must infer the difference.

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?

It clearly states the operating context ('SANDBOX ONLY') and the exclusion ('Fails on production'), which tells an agent when not to use it. However, it does not explicitly compare against the sibling simulation tool or explain when one should be chosen over the other.

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