TDQS

A4.2/5.0
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). The description adds genuinely non-obvious behavior: pricing at $0.02 per call, and that a stale feed is refused before payment, so no charge occurs. Rate limits and latency expectations are still unstated.

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?

Cost is front-loaded, then purpose, then input, then failure mode, then schema pointer. Every clause carries information; nothing is padding.

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

Completeness4/5

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

An output schema exists, so return values need not be spelled out, and the description wisely just points to it. Cost, input, and failure behavior are all covered; the cryptic "loopholetape://schema/..." reference is the only slightly opaque element.

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?

Schema coverage is 100%, so the single address parameter is already fully documented as a 32-44 char base58 Solana wallet. The description simply restates this ("Input: address (base58 wallet)") and adds no format or validation detail beyond the schema.

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: judging a new pump.fun token via its creator's prior launch history, with named evidence (graduations, rugs, median seconds to first sell). This distinguishes it clearly from siblings like mint_risk_card, token_check, and wallet_profile.

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?

"Use to judge a new pump.fun token by its creator's earlier launches" gives a clear triggering context. It never names an alternative tool or states when-not to use it, so it stops short of explicit routing.

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