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

With no annotations, the description carries the full burden and does reasonably well: it discloses concrete rate limits (3 calls/hour per IP, shared with the website), the paid path (x402 at $0.030/call), the flags produced (serial_minter, never_graduated), and explicitly scopes output to 'facts and flags only, never advice'. What is missing is whether the call is read-only/side-effect free, though the read-only nature is strongly implied.

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-loads the purpose, then flags, then guardrails, then pricing — a sensible order with no wasted preamble. The sales-y clause 'Data no feed reconstructs' is the one sentence that doesn't carry operational value.

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: counts, graduation rate against base rates, and named flags. Combined with the rate-limit and pricing disclosure, an agent has enough to invoke and interpret this correctly; only the exact response shape is left unspecified.

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?

Only one parameter, and its schema description already covers it at 100% ('Solana wallet address of the deployer'). The description adds no syntax, format, or validation detail beyond that, so the schema does the heavy lifting and a baseline 3 is appropriate.

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 resource and scope: the full launch record of a Solana wallet, enumerating what it returns (deployed token count, exchange arrivals, graduation rate vs base rates, serial-minter status). It is clearly distinct from generic siblings like launch/launches/chain, though it never names a sibling explicitly.

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?

The description never says when to reach for this tool versus siblings such as 'launch' or 'launches', nor any precondition beyond having a wallet. The only conditional content is commercial (free-tier limits and x402 pricing), which is not invocation guidance.

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