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

No annotations are provided, so the description carries full responsibility. It does not disclose whether the transaction opens, closes, or adjusts a position, potential reverts, permission requirements, or that it is a builder that does not send the transaction. The phrase 'unsigned transaction' hints at the builder role but is minimal.

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 a single, focused sentence that clearly communicates the core purpose without redundant words. It is front-loaded and appropriately sized for a simple, well-named tool.

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?

Given the complexity (13 parameters, dual-asset collateral/debt, slippage ranges) and no output schema, the one-sentence description is insufficient. It fails to explain the operational meaning of the parameters (e.g., that amounts represent changes, how slippage limits work, or the overall action 'interact' performs on a T4 vault).

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 coverage is high (92%), and individual parameter descriptions already explain each field. The tool description adds no additional parameter meaning, so it does not exceed the baseline of relying on the structured schema.

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 ('build') and resource ('unsigned transaction to interact with a Vault T4'), and explicitly mentions 'dual-asset collateral, dual-asset debt', which distinguishes it from T1/T2/T3 vault builders. It is clear what the tool does and which vault type it targets.

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 provides no explicit guidance on when to use this tool versus sibling vault builders (T1, T2, T3) or lending tools. It implies usage only through the vault type name, but does not explain selection criteria or scenarios where this tool is appropriate.

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