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

With no annotations, the description carries the full burden of behavioral disclosure. It discloses a confirmation step ('Confirm (yes/no) before executing'), DEX fees, and the DEX-forcing constraint. It also clarifies that account_fk is a database ID, not an address. However, it does not mention permissions, reversibility, or failure modes, so transparency is moderate.

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 first sentence is duplicated, creating redundancy. Despite this, the overall structure is clear, with a param list that segments information logically. The duplication is a notable flaw, but the description is not excessively verbose overall.

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 essential operational details: purpose, DEX constraint, fees, confirmation, and parameter sourcing. Since an output schema exists, return value details are not required. The main gap is the lack of differentiation from netfluid__crypto_dex_swap, but overall this is sufficient for an agent to invoke the tool in most situations.

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 has zero description coverage, but the description provides detailed meanings for all six parameters, including source endpoints (e.g., get digital_asset_fk from /crypto/digitalassets) and critical type clarifications (account_fk is a database ID and may not be 0). This goes beyond the schema and is useful for correct invocation.

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 that the tool swaps a digital asset for another via a blockchain DEX, using a specific verb and resource. It explicitly contrasts with /account/swap, but does not differentiate from the similarly named sibling netfluid__crypto_dex_swap, leaving some ambiguity about the exact boundary between the two.

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 mentions that this tool forces DEX swap and suggests using /account/swap for swapping between digital assets, giving some guidance on tool selection. However, it lacks explicit 'use this when...' criteria and does not address the relationship with the sibling netfluid__crypto_dex_swap, leaving potential confusion.

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