Lends Quote Psm Swap In

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

Annotations already provide readOnly, openWorld, idempotent, and non-destructive hints. The description adds 'current availability' (time-sensitive result) and 'exact' (precise quote), but it does not disclose failure modes, rounding behavior, or what happens when availability is insufficient. No contradiction with annotations.

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?

A single 10-word sentence that front-loads the verb and direction with no filler. Every word contributes to the meaning.

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?

For a one-parameter read-only quote tool, the core behavior is covered, but the missing parameter semantics and unspecified return shape (no output schema) leave an agent with only partial information. It is adequate but has clear gaps in unit and amount interpretation.

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 single parameter usdgAssets is not mentioned in the description despite 0% schema description coverage. The property name and pattern imply a non-negative integer amount of USDG, but units and whether it is the input amount to convert are left unstated, forcing the agent to guess.

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?

States a specific verb ('Quote'), a resource (PSM conversion), and the exact direction (USDG-to-leUSD), which lets an agent distinguish it from the sibling lends_quote_psm_swap_out. 'Current availability' adds scope beyond the generic title, making the purpose unmistakable.

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 sentence explains when to call this tool versus lends_quote_psm_swap_out or lends_prepare_psm_swap_in. There is no mention of prerequisites, ordering relative to prepare tools, or exclusions, so an agent must infer usage entirely from the name.

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