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

With no annotations, the description carries the full burden. It conveys that this is a read-only, public data retrieval ('published transparency data') and spells out exactly which transparency categories are included. It does not discuss caveats like staleness or auth, but for a zero-parameter read endpoint this is a clear behavioral disclosure.

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 with no filler; the data categories are listed compactly and the use case is front-loaded. Every sentence earns its place.

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 zero-parameter tool with no output schema, the description fully compensates by naming the data contents and the intended audit use case. An agent can decide whether to call it and what to expect without needing more detail.

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?

There are zero parameters and the input schema has 100% coverage, so the baseline is 4. The description has no parameter-specific details to add, and none are needed.

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?

Description clearly identifies the tool as returning blueDEX's published transparency data and enumerates the specific contents: treasury addresses, router allowlist, fee schedule, and paused venues. It also gives an explicit purpose (auditing quotes/transactions), which distinguishes it from the operational swap/quote/route siblings.

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 explicitly states the intended use case: 'Use this to audit quotes and transactions.' It does not enumerate when-not-to-use or name a specific alternative, so it falls just short of a 5, but the context signals show no overlapping read-verification sibling.

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