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

With no annotations provided, the description carries full burden. It discloses an auth requirement ('Requires API key') and indicates a read-only verification operation via 'Verify...'. It could more explicitly state that this tool has no side effects, but the 'verify' wording and the overall context imply a non-mutating check.

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 description is compact and front-loaded: the main purpose is stated first, followed by specific required/optional permissions with reasons, usage timing, and an auth reminder. Every sentence adds necessary information, with no fluff or redundancy.

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 simple one-parameter check tool with no output schema, the description covers the key context: purpose, permission details, when to use, and API key requirement. It does not describe the exact return format, but that is less critical for a boolean-style permission verification tool. Overall, it is sufficiently complete for a tool of this simplicity.

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 100% for the single optional parameter poolAddress, which explains its meaning and default behavior. The tool description adds no extra parameter-level detail beyond the schema, so the baseline score of 3 applies.

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 uses a specific verb ('Verify') with a clear resource ('required active permissions on your pool address'). It distinguishes itself from sibling tools by focusing on checking/verification rather than building or broadcasting permission transactions.

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?

Explicitly states when to run this tool: 'Run this after granting permissions to confirm the platform can operate your pool.' It also differentiates from alternatives by listing the required vs optional permissions, implying that permission-granting tools are the prior step. This gives clear context for selection among permission-related siblings.

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