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

Annotations already carry readOnlyHint, idempotentHint, openWorldHint, and destructiveHint, so safety is covered. The description adds one genuinely useful trait by calling the risk score 'heuristic,' signaling it is an approximation rather than a verdict, but says nothing about data freshness, caching, rate limits, or cost.

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?

One sentence, front-loaded with the verb and the full return inventory, with zero filler. The enumerated field list is dense but each item earns its place by telling the agent what it will get back.

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 no output schema, the description correctly carries the burden of describing return contents and does so comprehensively across authority, metadata, holders, and score. Minor gaps remain around data freshness and how the concentration/risk values are computed or scaled.

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 'mint' parameter, so the schema already supplies base58 format and meaning. The description adds no syntax, network, or validation detail beyond it, which is the expected baseline when the schema does the work.

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 states a specific verb ('Return') and an enumerated set of outputs for a clearly bounded resource: a token mint. That resource is unambiguous against the siblings explain_transaction and inspect_wallet, though the description never names or contrasts them explicitly.

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?

There is no when-to-use statement, no prerequisites, and no guidance on alternatives. 'Heuristic rug-risk score' implies due-diligence usage, but the agent must infer that entirely from the noun phrase rather than from any stated condition.

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