styx_price

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

With no annotations, the description carries the full behavioral burden. It discloses that the price is current and denominated in USD from Styx, but it omits update frequency, staleness behavior, authentication needs, rate limits, and response shape.

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 first sentence is front-loaded and complete. The second sentence is a tangential cross-promotional tip that is brief but does not earn its place as essential tool-selection guidance.

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 zero-parameter price getter with no output schema, the description gives enough to call it correctly: it returns the current BTC price in USD from Styx. More detail about freshness or response format would improve completeness but is not strictly required at this complexity.

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?

The tool has zero parameters, so the baseline is 4. There are no parameter semantics to clarify or compensate for.

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 states a specific verb, resource, asset, currency, and source: 'Get current BTC price in USD from Styx.' This clearly distinguishes it from sibling price- or status-oriented tools such as get_bns_price, styx_status, and styx_pools.

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 is given on when to choose this over alternatives or when not to use it. The only usage-like sentence is a cross-sell tip pointing to `earning_opportunities`, which does not help select among any price-related sibling tools.

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