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

With no annotations, the description carries the full burden and does so thoroughly. It discloses the $0.05 per call cost, authentication requirements (x402 or subscriber API key), the data source, the output limitation ('bias/score/factors verdict only — raw candles are not redistributed'), and an educational-data disclaimer.

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 core purpose is front-loaded in the first sentence, but the rest of the description packs pricing, payment mechanics, header options, and catalog referral into a dense single block. This information is useful, but it could be better structured for readability.

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?

Given no output schema and no annotations, the description provides enough context for selection and invocation: what the tool computes, input semantics, chain defaults, cost, authentication, and return scope. It also clarifies that raw candles are not provided, which sets accurate expectations.

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%, and the schema only lists token and chain with no explanations. The description significantly enriches both: token is defined as 'mint address or symbol', and chain is described as optional with a default of solana and allowed values enumerated (solana/base/bsc/ethereum).

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 identifies the tool as a 'VWAP/Bollinger/RSI/MACD confluence read on a fresh memecoin launch' using GeckoTerminal OHLCV data. It specifies the exact indicators and asset type, distinguishing it from sibling tools like get_memecoin_movers or get_signals.

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 description gives useful context—such as token input, chain options, and a pointer to browse with get_catalog—but does not explicitly state when to prefer this tool over alternatives or when not to use it. Usage is implied rather than directly contrasted with siblings.

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