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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description contributes the cost model ('$0.005 USDC'), which is genuinely useful context an agent cannot get elsewhere, but it says nothing about latency, rate limits, or failure modes for an invalid mint address.

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?

A single well-formed sentence with the inspected fields front-loaded and the price tucked into a parenthetical. Nothing is redundant, though the parenthetical pricing note slightly interrupts the enumeration of what is inspected.

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 one-parameter read-only oracle with a fully described schema, rich annotations, and an output schema, the description covers what is inspected and what it costs. What remains missing is minor: how the three inspected fields should be interpreted and what happens on an invalid or non-mint address.

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 is a single parameter with 100% schema description coverage ('Solana SPL Mint base58 address'), so the schema carries the semantics. The description adds no format hints, validation rules, or examples beyond what the schema already states, which is the expected baseline at high coverage.

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 names a specific verb ('Inspects') and resource ('SPL token mint parameters') and enumerates the concrete fields examined: freeze authority, mint revocation, and supply metrics. That distinguishes it clearly from every sibling tool, none of which touch Solana mint risk. It falls short of 5 only because 'risk' in the tool name is never connected to how those parameters imply risk.

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 guidance on when to call this versus another tool, no prerequisites, and no stated exclusions. The only implicit cue is the mention of freeze authority and mint revocation, which hints at a token-safety use case, but an agent must infer that itself.

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