getCryptocurrency1MinuteData

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

Annotations already establish readOnlyHint, idempotentHint and openWorldHint, so safety is covered. The description adds that the payload includes price and trading volume, which is genuine extra context, but it adds nothing about intervals served, date defaults, or response granularity. The 'real-time' claim is slightly at odds with a date-range (from/to) parameter, which suggests historical intraday retrieval rather than a live feed.

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?

Two sentences, front-loaded with the core action and interval. The second sentence is partly marketing filler ('stay updated on market movements') but it does convey the price-plus-volume payload, so it earns partial keep.

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?

For a simple read-only, three-parameter tool with full schema coverage and no output schema, the description is adequate but leaves gaps an agent would care about: whether date range is required for meaningful output, and how this differs from the adjacent 5-minute/1-hour tools.

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 is 100% and each of the three parameters (symbol, from_date, to) carries its own format description, so the schema does the heavy lifting. The description mentions neither the symbol format nor the date range, adding no meaning beyond the schema — baseline 3 applies.

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 gives a specific verb and resource ('Get ... 1-minute interval price data for cryptocurrencies') and names the underlying API. The 1-minute interval is stated explicitly, but it never contrasts itself with the close siblings getCryptocurrency5MinuteData and getCryptocurrency1HourData, so the interval distinction rests on the tool name alone.

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?

Usage is only implied by 'Monitor short-term price fluctuations and trading volume' — an agent can infer this is for intraday/short-horizon analysis. There is no explicit when-to-use versus the 5-minute or 1-hour variants, and no guidance on date-range expectations or limits.

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