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

No annotations exist, so the description carries the full burden. It usefully discloses the monetary cost ($0.005 USDC per call) and summarizes the return values. It omits other behavioral context such as what 'recent' means, whether the data is real-time, or any permission requirements.

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?

Three tight sentences front-load the action and output, then disclose cost. Each sentence earns its place, though the cost sentence could arguably be a separate annotation rather than description content.

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?

The description explains return values even without an output schema, which is helpful. However, with no annotations and an analysis tool whose time window and sentiment methodology are undefined, it leaves gaps that could affect how an agent interprets or trusts the result.

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% and the sole parameter (mintAddress) is fully documented in the schema, so the baseline is 3. The description adds no parameter-level detail beyond the schema, which is acceptable given this high coverage.

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 verb and resource: tracking wallets that are accumulating or dumping a token based on transfer activity. It also names the outputs (top movers, net flow, sentiment). It doesn't explicitly differentiate from close siblings like token_holders or smart_money, but the purpose is clear.

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 by 'based on recent transfer activity'; there is no explicit when-to-use, when-not-to-use, or alternative tool recommendation. With siblings such as token_holders, smart_money, and copy_trade_signals, the agent gets no routing guidance.

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