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

No annotations are provided, so the description must carry full burden. It does not disclose any behavioral traits such as read-only safety, data source, time range limitations, or return format. This is a significant gap for a data-fetching tool.

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?

Single sentence, no filler, immediately front-loaded with the verb. Efficient.

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, the description should explain what data is returned (e.g., OHLC, price at timestamp). It does not, nor does it mention exchange compatibility or required format for symbol pairs. For a 4-parameter tool, this is incomplete.

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 coverage of 100% means each parameter has a description. The tool description adds no extra meaning beyond the schema; it merely restates 'historical price data' without explaining the relationship between from/to and timestamp. Baseline at 3 is appropriate.

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 uses a clear verb ('Get') and identifies the resource ('historical price data') with scope ('for a cryptocurrency on a specific exchange'), which separates it from broader market tools. However, it does not explicitly distinguish from similar historical price tools like market_get_coin_chart or defi_get_token_price_history, though the exchange specification helps.

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?

No guidance on when to use this tool versus alternatives; no mention of alternatives, prerequisites, or context. The description simply states the function, leaving the agent to infer when it is appropriate.

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