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

No annotations are provided, so the description carries the full burden. It usefully discloses the pay-per-call cost ($0.02 USDC) and the underlying route, which are real behavioral facts an agent needs, but says nothing about rate limits, auth, or error behavior.

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?

A single dense sentence front-loads the value proposition and enumerates contents; the trailing route and price add practical detail. No filler, though the endpoint path is somewhat redundant with the schema.

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?

With no output schema and no annotations, the description effectively serves as the return-value contract by listing the data categories returned. Remaining gaps are format and pagination specifics, which are minor given how completely the payload is enumerated.

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% with both parameters documented (symbol ticker and interval enum with default), so the schema does the heavy lifting. The description's route string '/x/crypto/deep/:symbol' merely confirms symbol is a path parameter without adding new semantics.

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?

States a specific verb+resource: an aggregated 'full decision pack' for a crypto coin, and enumerates exactly what it bundles (spot + 24h stats, last candle, RSI/EMA/SMA, funding + open interest, order-book spread/imbalance). This clearly distinguishes it from the sibling component tools like crypto_price, crypto_indicators, crypto_orderbook, and crypto_derivatives.

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 phrase 'in ONE call' implies the consolidation value proposition versus calling the individual sibling tools, but it never explicitly names an alternative or states when not to use it. Usage is inferable rather than spelled out.

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