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

Goes well beyond the readOnlyHint/openWorldHint annotations by disclosing the data source (free public data only), a 60-second per-mint cache, and a 20 calls/minute per-client rate limit, plus that this route returns only a subset of flags versus paid routes. These are operationally relevant traits an agent would otherwise have to discover by trial.

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?

Purpose is front-loaded, but the text carries promotional framing ('Try free, then pay per call') and a trailing bracketed banner ('[falcon.sol solana-wallet-intel. Free, no payment.]') that adds no invocation guidance. Every sentence should earn its place; a couple of them don't.

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 compensates by listing the returned fields and the one-line verdict. Combined with the rate limit and cache notes, an agent has enough to call it correctly; only error behavior and output shape details are left to the schema.

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 coverage is 100% and already documents the single base58 mint argument and the 400 on invalid input. The description only adds that it is one mint per call and that the route is free, which is marginal beyond the schema.

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?

States a specific verb and resource: pass one Solana token mint, get a rug-check. It even enumerates the returned fields (riskScore, riskLevel, verdict, flags, liquidity, market cap, age, pump.fun status), so an agent knows exactly what it produces. It is not explicitly contrasted with sibling tools like token_trending, which keeps it from a 5.

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?

'Free demo. Try free, then pay per call' plus 'The paid routes return every flag, the full on-chain checks, and wallet intelligence' establishes clear context for choosing this cheap/free subset over paid tiers. No explicit when-not-to-use or sibling alternative is named, so it falls short of a 5.

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