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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive, so the safety profile is covered. The description adds which data fields come back (tokens, bond rate, peak market caps), but says nothing about the metered/payment behavior implied by x_payment, pagination semantics, or the cost of a call — meaningful gaps for an open-world paid endpoint.

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 compact sentence with the resource and returned fields front-loaded and no filler. Nothing in it is redundant or misplaced, even if it is on the terse side.

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?

An output schema exists, so return values need not be explained, and the four parameters are fully documented in the schema. However, for a paid, open-world, paginated tool, the description omits the payment/key prerequisite and paging expectations, leaving an agent reliant on reading the schema closely before calling.

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%, including base58 address, limit/offset paging, and the x402 payment flow, so the schema already carries parameter meaning. The description contributes no additional parameter detail, which is the baseline-3 case when the schema does the work.

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 states a specific resource and scope: the full launch history of a single token deployer, enumerating tokens, bond rate, and peak market caps. That is clearly distinct from siblings like scan_token or profile_wallet, though the description never explicitly contrasts itself with them, relying on the title to carry the differentiation.

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 guidance at all: no mention of when to prefer this over profile_wallet (which also takes a wallet address) or scan_token, and no note about prerequisites such as needing a paid x402 quote or Pro key. The agent must infer the selection criteria entirely from the name and title.

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