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

Annotations are empty, so the description carries the full burden. It discloses that the DEX charges fees, unsupported tokens are not displayed in balances, and a confirmation is required. However, it omits important behavioral traits for a financial mutation: reversibility, slippage tolerance, network confirmation delays, or whether funds are locked. This is partial but not comprehensive.

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 opening sentence is duplicated almost verbatim: 'Swaps a token for another token...' appears twice with a minor parenthetical addition. This redundancy wastes space and reduces clarity. The @param blocks are useful, but the repeated sentence is a clear structural defect.

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 covers the core function, all six parameters, fees, unsupported-token behavior, and confirmation. Since an output schema exists, the lack of detailed return info is acceptable. However, it omits operational details like slippage or network confirmation expectations, making it only partially complete for a financial transaction with no annotations.

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%, but the description compensates thoroughly by documenting every parameter with meaningful context. For example, account_fk is explained as 'a database ID (int) not an account address (str) and may not be 0', and token is identified as 'the wallet_api_token provided by /access/login'. This is essential semantic value beyond the raw schema types.

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 action: 'Swaps a token for another token using a Distributed Exchange (DEX) on the blockchain.' It adds the qualifier 'token (not a digital asset)' and specifies the DEX mechanism, which helps differentiate from siblings like netfluid__crypto_swap. However, the distinction is not explicit enough to fully exclude all alternative swap tools.

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 given on when to use this tool versus alternatives such as netfluid__crypto_swap or netfluid__account_swap. The description mentions a confirmation step ('Confirm (yes/no) before executing') but does not discuss prerequisites, exclusions, or typical use cases. Sibling tools are not referenced.

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