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

Adds genuinely useful behavioral context not present in annotations: the $0.25-per-successful-call prepaid cost model and the single-wallet scan scope. However, the 'scan' framing sits uneasily with readOnlyHint=false, and the description never explains why a scan is non-read-only or what side effect justifies that flag, leaving the agent with an unresolved ambiguity.

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?

Two tight sentences with no filler; the cost model is front-loaded ahead of the purpose. One could argue the price should follow the purpose, but every clause carries information.

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, so the description should ideally state what an audit returns (fees by launchpad, totals, claimable status). It covers purpose, cost, and scope but omits return shape and any auth/prepaid-credit prerequisites for this paid call.

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 0%, so the description must carry the single 'wallet' parameter. 'One-wallet scan' implies the input is a single wallet but adds no address format, chain, or validation detail beyond that, so it only partially compensates for the coverage gap.

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 ('scan ... for unswept or unclaimed creator fees') plus scope ('one-wallet', 'across supported launchpads'). An agent can tell what the tool returns without opening the schema. It does not name or distinguish any of its siblings (e.g., claim_worth_it, launch_economics), which keeps it below 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?

There is no when-to-use/when-not-to-use guidance and no routing to alternatives, even though siblings like claim_worth_it and launch_economics plausibly overlap. The task is only implied by the wording 'scan ... for unswept or unclaimed creator fees'.

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