Simulate — method + revert + risk level (FREE)

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

With no annotations provided, the description carries the burden of behavioral disclosure. It discloses that it produces a 'real result' and requires 'no wallet', which is useful, but it does not state whether the operation is read-only, what 'risk level' means, or any limitations like rate limits or API key requirements. It adds some context but leaves notable gaps.

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 two sentences, front-loaded with 'FREE', and immediately states the core outputs. It avoids redundancy, clearly separates the free vs. full offerings, and every phrase adds value. It is a model of conciseness.

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 tool has 5 parameters and no output schema, and the description mentions the output categories but not their structure or possible values. It is adequate for a simple free simulation tool, yet leaves the agent uncertain about the exact response format and edge cases. Given the complexity, a bit more detail would be expected.

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 baseline is 3. The description does not add parameter-specific detail beyond what is already in the schema, but it does contextualize the parameters by listing the output types they influence (method, revert, risk level, effect types). No meaningful enhancement is provided.

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 identifies the tool as a simulation service that returns method, revert flag, risk level, and predicted effect types for a transaction. It distinguishes itself from the sibling 'simulate' tool by explicitly framing this as the free tier and naming the upgrade path.

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 implies usage by contrasting with the paid 'simulate' tool: the free version provides method, revert, risk level, and predicted effect types, while the full version adds 'predicted deltas + all risk flags'. This gives an explicit alternative, though it does not detail when to choose one over the other beyond feature comparison.

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