A4.3/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, open-world), but the description adds genuinely new behavioral context: cost per call ($0.02), the classification categories returned, and that a stale feed is 'refused before payment' so no charge occurs. This goes beyond what annotations provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads cost and purpose, then moves to exclusion, input format, payment behavior, and schema reference in a tight, waste-free sequence. Every clause carries information an agent needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value explanation is unnecessary, and the description points to it via the loopholetape schema reference. Cost, usage, exclusion, input, and stale-feed behavior are all covered, leaving nothing an agent needs to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With a single parameter at 100% schema coverage, the schema already documents the base58 address (32-44 chars) fully. The description's 'Input: address (base58 wallet)' merely restates the schema rather than adding format or validation detail, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: classify a wallet that buys pump.fun tokens into named categories (insider, latency_bot, skilled) and read its PnL. It explicitly distinguishes itself from sibling mint-risk tools with 'Not a mint's risk', so an agent can tell it apart without opening other schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives clear context for use ('classify a wallet that buys pump.fun tokens' and read PnL when it ranks on the leaderboard) plus an exclusion ('Not a mint's risk'). It stops short of naming the specific alternative tool an agent should use for mint risk, so it doesn't reach a full 5.

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