debank_simulate_transaction_tool

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

With no annotations provided, the description carries the full burden. It discloses that the tool performs simulation without real side effects, provides safety analysis including risk level, warnings, recommendations, and estimated gas costs. Lacks details on authorization but sufficient for a simulation tool.

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 concise, with a critical safety note front-loaded, followed by an Args section and Returns summary. Every sentence adds value; no redundancy.

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?

The description covers inputs and high-level returns. Since an output schema exists, it does not need to enumerate all return fields. It adequately addresses the complexity of a simulation tool with nested objects.

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 schema has 0% description coverage, but the description adds detailed meanings: transaction_data required fields, pending_transactions as optional simulation queue, explain_only controlling full simulation vs explanation. This fully compensates for the schema gap.

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 clearly states 'Pre-execute and explain a transaction using DeBank's simulation' and emphasizes it as a critical safety tool. It distinguishes from sibling tools that are primarily read-only queries.

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 explicitly advises 'Always simulate transactions before sending to avoid costly mistakes and security issues', implying its use precedes actual transaction execution. It does not explicitly state when not to use, but the context is clear.

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