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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description usefully adds behavior annotations lack — a pricing model ($0.03 or a plan key) and the 100-transfer filtering rule — but says nothing about result shape, pagination, or whether the 100-transfer threshold is a hard filter, leaving behavioral gaps.

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 front-loaded sentence carrying the core semantics, with the payment note parenthetically appended. No filler, though the cost parenthetical slightly dilutes the payload-first structure.

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 lookup with no output schema and annotations covering safety, the description supplies the returned content in enough detail that an agent could decide relevance and call it correctly. The pricing note closes the last practical 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% for the single 'address' parameter, so the baseline is 3. The description implies the address must be an Arc wallet but adds no format or validation detail beyond the schema's 'Arc wallet address 0x…'.

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 resource ('An Arc wallet's launch record') and enumerates what it contains: tokens minted that reached 100 transfers, launchpads used, and counts reaching 1,000 transfers. This is far more informative than a tautology, but it never contrasts itself with the neighboring robinx_deployer or robinx_arc_token tools (e.g. why use this over the general deployer), so an agent must infer the boundary.

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 explicit when-to-use or when-not-to-use guidance and no named alternative, despite several plausibly overlapping siblings (robinx_deployer, robinx_arc_token, robinx_arc_launchpads). The only routing hint is the implicit 'Arc wallet' scope, which is weak guidance at best.

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