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

Goes well beyond the readOnlyHint/openWorldHint annotations by disclosing the paid-call model: $0.01 USDC per call via x402 on Base mainnet, the exact failure mode (unpaid call returns an x402 PaymentRequired challenge), and the precise remediation (retry the identical call with the signed payload in _meta["x402/payment"]). That is exactly the operational context an agent cannot infer from structured fields.

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?

Three tight sentences: purpose and sources first, return value second, payment protocol third. No filler, and the critical payment/retry instruction is not buried.

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?

No output schema exists, but the description states the return value (a verdict on ICS-targeting campaign linkage), and the payment workflow is fully specified, which is the main complexity for this tool. It stops short of describing verdict granularity or confidence fields, leaving a small gap.

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% with only two required parameters (value, type) and an enum for type, so the schema fully documents the inputs. The description adds no parameter-level detail such as accepted IOC formats, so the 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?

Names a specific verb+resource (IOC enrichment), the upstream sources (AlienVault OTX, AbuseIPDB), and the concrete output (verdict on ICS-targeting campaign linkage). This is clearly distinguishable from siblings like getThreatActor, getMalwareProfile, or getThreatScore.

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?

Usage is implied by the name and the stated output: call it to enrich a single IP or domain. However, it never says when to prefer this over adjacent enrichment/context tools (getThreatScore, getCveTriage, getMalwareProfile), nor does it mention prerequisites such as wallet/payment setup beyond the mechanics of the failed-call retry.

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