Top up junior note

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

No annotations are provided, so the description carries full burden. 'Add USDST to junior note' implies a financial transaction/mutation, but doesn't disclose behavioral traits like: whether this requires specific permissions, if it's reversible, what happens if the note doesn't exist, potential fees, or confirmation requirements. The description is minimal and lacks crucial operational context.

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 extremely concise at just 5 words. It's front-loaded with the core action and resource. There's zero wasted language or redundancy. While it may be too brief for completeness, it's structurally efficient.

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 this is a financial transaction tool with no annotations, 0% schema description coverage, and no output schema, the description is inadequate. It doesn't explain what a 'junior note' is, what 'top up' accomplishes operationally, what happens after execution, or any error conditions. For a tool that presumably moves funds, this leaves too many questions unanswered.

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 0%, so the description must compensate. It mentions 'USDST' which relates to the 'amountUSDST' parameter, providing some context about the currency/unit. However, it doesn't explain the parameter's purpose, format (e.g., decimal string, integer), constraints, or typical values. With only 1 parameter, this is a significant gap in documentation.

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 states the action ('Add') and target resource ('junior note'), but lacks specificity about what 'top up' means in this context. It distinguishes from some siblings like 'claim-junior-note' or 'open-junior-note' by implying an addition operation, but doesn't clarify how it differs from 'deposit' or other financial operations in the CDP namespace.

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?

No guidance is provided on when to use this tool versus alternatives. With multiple CDP operations available (deposit, withdraw, mint, repay, etc.), the description doesn't indicate whether this is for increasing collateral, adding funds to an existing position, or another specific use case. No prerequisites or exclusions are mentioned.

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