ws_snapshot_ticker

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

No annotations provided; description claims 'real-time' and 'faster' but fails to disclose any behavioral traits like read-only nature, WebSocket token requirements, or snapshot semantics (e.g., ephemeral, point-in-time).

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, front-loaded sentence with no redundant information. It efficiently conveys purpose, though brevity limits completeness.

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 description is minimal for a tool with one parameter and no output schema. It omits details about return structure (e.g., price fields, timestamp) which would aid an agent in interpreting results.

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% for the single parameter 'pair', with a clear example in the schema description. The tool description adds no extra parameter information beyond the schema, meeting the baseline for high coverage.

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 it retrieves a 'real-time price snapshot' via WebSocket, distinguishing it from REST-based tools like ticker by highlighting speed. However, it could specify what data the snapshot contains (e.g., last price, bid/ask).

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 use when speed is prioritized but provides no explicit guidance on when to use this tool versus siblings like ticker or ticker_all. No when-not-to-use or prerequisites mentioned.

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