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

No annotations are provided, so the description must convey behavioral traits. The description only states that it 'gets' launches and includes market cap and volume, which implies a read-only operation. However, it does not explicitly state read-only status, potential rate limits, authentication requirements, or any side effects. The description is insufficiently transparent for a tool with zero annotation coverage.

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?

The description is a single, short sentence with no filler or redundancy. It front-loads the core action and key details, making it easy to scan. It earns its place without wasted words.

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 simple getter tool with one optional parameter and no output schema, the description should at least explain the return structure or any constraints. It states that launches come 'with market cap and volume' but does not describe any other output fields, ordering, or the meaning of 'newest'. Without an output schema, the agent lacks clarity on what the tool returns. The brevity leaves important context unaddressed.

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?

The input schema has one optional parameter, 'limit', with no description. Schema coverage is 0%, and the tool description does not mention 'limit' at all. An agent cannot infer what 'limit' controls (e.g., number of results, pagination, time range) from either the schema or the description. The description fails to compensate for the lack of schema documentation, leaving the parameter's meaning entirely ambiguous.

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 clearly states the verb 'Get' and the resource 'newest token launches on Zora', and specifies the data fields (market cap and volume). It is specific enough to convey the tool's core function, but it does not explicitly differentiate from siblings like zora_scanner, which might also return launch information. The purpose is unambiguous and actionable.

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 guidance on when to use this tool versus alternatives. The sibling list includes other Zora-related tools (e.g., zora_scanner, zora_rug_check), but the description does not mention any conditions, exclusions, or preferences that would help an agent decide between them. The usage context is entirely absent.

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