Arc launchpads since genesis

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful inclusion semantics (tokens counted only after reaching 100 transfers) and scope, but says nothing about ordering, result shape, or pagination behavior beyond the limit parameter.

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 dense sentences front-load the scope and then pile on the metrics and entity examples; every clause carries data. Slightly overpacked but no filler.

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 read-only list endpoint with a one-parameter schema and annotation-covered safety, the description gives enough scope and inclusion criteria to call it correctly. It leaves return shape and ordering unspecified, a minor gap given the absence of an output 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?

There is a single optional parameter (limit) with 100% schema coverage, including its range and default in the schema. The description adds no further detail about it, which is acceptable given the schema already documents it, 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?

The description names the exact resource (launchpads and factories), the chain and its ID (Arc, 5042), the time scope (since genesis), and the metrics surfaced (100/1,000-transfer thresholds, 24h/7d launches). It does not explicitly distinguish itself from the near-sounding sibling robinx_arc_new_launches, so an agent must infer the difference.

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 or when-not-to-use guidance, and no named alternative despite overlapping siblings such as robinx_arc_new_launches. The agent can guess the intent from the scope, but nothing tells it when this tool is the right pick over a sibling.

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