postCryptoLoanFixedSupply

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

No annotations are provided, so the description must disclose behavioral traits. It mentions a rate limit but omits details like required permissions, fund locking, or destructive effects. For a financial mutation tool, this is insufficient.

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?

Two concise sentences: one for purpose, one for rate limit. It's front-loaded and efficiently worded, though the rate limit could be moved to annotations.

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?

With 5 parameters, no parameter descriptions, no output schema, and no annotations, the description is severely incomplete. It fails to explain how to use parameters, return values, or prerequisites.

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 0% (no parameter descriptions in the schema), and the description adds no meaning to any of the 5 parameters. The agent gets no help understanding orderCurrency, orderAmount, etc.

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 'Lend crypto to earn fixed interest.' This is a specific verb+resource, and it distinguishes from sibling tools like postCryptoLoanFixedBorrow (borrowing) by explicitly mentioning lending.

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 on when to use this tool vs. alternatives (e.g., postCryptoLoanFlexibleBorrow or other loan tools). The description only states the action without context for selection.

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