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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and open-world, so the safety profile is fully covered. The description adds the pagination behavior ('page through'), which is useful, but says nothing about result ordering, page size, or whether all launches or only successful ones are returned — details an agent would want when iterating.

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 sentence with no filler, and the key information (enumeration scope, pagination, platform) is front-loaded. Nothing is repeated from the title or annotations.

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 two-parameter read tool with full schema coverage and complete annotations, this is adequate but thin: with no output schema, the description could have told the agent what a 'coin' entry contains or how pages terminate. Ordering and empty-result behavior are left unstated.

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%, so the schema already documents both wallet and cursor, giving a baseline of 3. The description does add one piece of meaning — the wallet is interpreted as a creator address rather than an arbitrary holder — but cursor mechanics and any ordering guarantees remain unexplained beyond the schema.

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 gives a specific verb-plus-resource combination ('page through every coin a wallet has launched') and names the platform (higher.fun), which is enough to distinguish it from get_coin (single coin), list_coins (all coins), and get_wallet_positions (holdings). It stops short of explicitly contrasting with those siblings, so it lands at 4 rather than 5.

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?

Usage is only implied: an agent can infer this is the tool for enumerating a creator's launches, and 'page through' signals pagination. There is no statement of when to prefer it over list_coins or get_wallet_positions, and no note on prerequisites or edge cases (e.g. wallets that have launched nothing).

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