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

With no annotations, the description carries the full burden and does well: it discloses the free-tier limit (3 calls/hour per IP, shared with the website), the paid path ($0.015/call over x402 at /v1/launch), and the framing constraint 'facts and flags only, never advice'. It does not explicitly state that the operation is read-only or note caching/return shape, keeping it short of a 5.

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 with the core question and its answer fields before the commercial details. Dense but every clause carries information; the pricing/URL tail is relevant but slightly heavy for a description.

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 must convey return content, and it does (launch count, graduation record, creator buy behavior). Combined with rate-limit and cost disclosure for a one-parameter read tool, an agent has everything needed to call it correctly.

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?

Single parameter with 100% schema description coverage, so the schema already fully documents 'mint' as the Solana mint address. The description adds no syntax or format detail beyond that, which matches the baseline 3 for high coverage.

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 question it answers ('Who launched this pump.fun token and what happened to their previous ones') and enumerates the return fields: launch count, graduation record, and creator bonding-curve purchases. It is clearly a creator/launch-history lookup, but it never distinguishes itself from the very similar siblings 'deployer' and 'launches', leaving overlap unresolved.

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 guidance and no alternative tool is named, despite obvious candidates in the sibling set (deployer, launches). The only conditional information is pricing tiers, not usage selection.

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