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

With no annotations, the description is the only source of behavioral context. It does disclose that the tool reports leaderboard-derived wallet classes, holdings, and conditional creator stats, and the '$0.02' prefix hints at a cost, but it never explicitly states that the operation is read-only or describes error/freshness behavior. The name 'profile' and the passive data language make a read-only lookup the reasonable inference.

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 one compact sentence that packs in the core output categories and the classification labels without redundancy. The leading '$0.02:' is slightly cryptic and competes with the main purpose for attention, but the rest is efficiently structured and front-loaded with the key result.

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 one-parameter lookup with no output schema, the description gives a reasonable high-level picture of the response: wallet class, holdings, and creator stats. It does not cover the input format, exact return shape, or relationship to sibling tools, but the tool is simple enough that an agent can likely invoke it correctly with the address parameter alone.

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 0%, so the description must compensate for the 'address' parameter. It only does so implicitly through 'wallet class' and 'wallet profile', making it clear that address refers to a wallet identifier, but it does not specify format, chain, or examples. For a single self-descriptive parameter this is adequate but minimal.

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 identifies a specific resource (wallet profile) and the concrete output: wallet class (insider/sniper/skilled/crowd), holdings among recent mints, and creator stats. It does not use an explicit verb like 'retrieve' or 'returns', and it does not name a sibling tool, so it stops short of full 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?

The single required 'address' parameter and the phrase 'wallet class from our rolling PnL leaderboard' imply the tool is for analyzing a wallet address, which is enough to infer a basic use case. However, the description gives no explicit when-to-use guidance, exclusions, or comparisons to siblings such as creator_reputation or market_regime.

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