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

With no annotations, the description carries the burden of behavioral disclosure. It explicitly states that the tool 'build[s] an unsigned transaction' (indicating no execution) and that the underlying function is 'payable', both useful behavioral details. It does not mention return format or side effects, but for a transaction-builder, these disclosures are significant.

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 the core purpose, and includes only essential additional context (payable). Every word serves a purpose; there is no redundancy or filler.

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 adequately covers the tool's purpose and key behavioral trait for its complexity. While there is no output schema, the description implicitly states the output is an unsigned transaction. The schema handles parameter details, and the description gives enough context to use the tool correctly for T1 vault interactions.

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 already provides descriptions for 6 of 7 parameters (86% coverage), so the description does not need to elaborate on parameter semantics. The description adds no additional parameter-level meaning beyond what the schema provides, matching the baseline for high schema coverage.

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 the tool's function with a specific verb ('Build') and resource ('unsigned transaction to interact with a Vault T1'). It further distinguishes from sibling tools by specifying 'single-asset collateral, single-asset debt', setting it apart from T2/T3/T4 vault operations.

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 clear context for when to use the tool: when interacting with a Vault T1. It implies this is the appropriate tool for T1 vaults via the explicit 'T1' designation and the collateral/debt definition. However, it does not explicitly state exclusions or alternative tools.

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