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

Goes well beyond the readOnly/idempotent/non-destructive annotations by disclosing cost ($0.025 per call, 10 free/day, then a payment-required result listing x402 options) and error semantics (isError with message for invalid input or upstream failure, and not charged). It also explains the composition behavior — three signals folded into a single verdict — which is real behavioral context an agent can't get from annotations.

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?

Front-loaded well — verdict, outputs, then usage — but the parenthetical repeating 'on the A.U.G.U.R Foresight · Pump & LP server, https://augur-trade.com/hub/mcp/pump' three times in one sentence is pure padding that inflates the definition without adding decision value.

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?

An output schema exists, so return shape needn't be explained, and the description still covers the remaining agent-critical unknowns: what's aggregated, cost model, free tier, and failure/charging behavior. Nothing an agent needs in order to call this correctly is missing.

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 the schema already defines mint as a base58 pump.fun token mint with a regex pattern, so the description adds nothing about the parameter itself. The only implicit clarification ('pump.fun launch') restates what the schema says; baseline 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?

Opens with a concrete verb+resource ('One call, one verdict on a pump.fun launch') and enumerates exactly what comes back: 0-100 score, positives/risks, graduation odds, dev record, snipers, holders, flow. It also names the three underlying signals it bundles, so an agent knows precisely what this produces versus the plain sibling tools like token_risk or price.

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 labeled 'When to use: The one-call verdict on a pump.fun launch' and justifies the choice against the alternative of calling pump_token/pump_dev/pump_odds separately on cost grounds. It stops short of stating when NOT to use it (e.g., if only one signal is needed), which keeps it from a 5.

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