get_token_price_comparison

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 discloses the core behavior (comparing prices) but does not specify the output format, such as whether it returns a percentage, absolute difference, or a structured object. This is adequate but lacks detail on return value or potential side effects.

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 description is a single, focused sentence that conveys the essential purpose without waste. It is well-structured and front-loaded, making it easy for an agent to parse quickly.

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?

The tool has no output schema and no annotations, so the description must cover the essentials. It does explain the main purpose but omits details like the result format, units, or edge-case handling (e.g., equal timestamps). Suitable for a simple tool but not comprehensive.

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%, so the baseline is 3. The description adds minimal meaning beyond the schema—it only reinforces the 'between two timestamps' relationship. No additional parameter details are given, but the schema already documents each parameter sufficiently.

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 states the tool's function: comparing token price between two timestamps to show price change. This explicitly distinguishes it from sibling tools like get_current_token_price and get_historical_token_price, which do not involve comparison between two points in time.

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 implies the use case: when users need to compare prices at two different timestamps. It does not explicitly name alternatives or exclusions, but the context is clear given the sibling tool names and the 'between two timestamps' phrasing. A brief mention of when not to use it would push it to 5.

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