coinpaprika_ticker

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 default behavior (top 20 without an id) and implies a read-only operation, but says nothing about rate limits, auth requirements, or the shape/fields of the returned ticker data.

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 short sentences, zero waste, with the core purpose front-loaded and the default-behavior caveat immediately after. Nothing redundant.

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 single-optional-parameter read tool with no output schema and no annotations, the description covers purpose and the key default-behavior edge case. It could add a bit more on return fields, but it is largely sufficient for correct invocation.

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 optional 'id' parameter is already documented. The description adds genuine meaning beyond the schema by explaining the consequence of omitting id (returns top 20), which the schema does not state.

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?

States a specific verb ('Get') and resource ('live price/ticker data') scoped to Coinpaprika. It is clear what the tool returns, though it does not explicitly differentiate itself from close siblings like coinpaprika_coin or coinpaprika_global, which an agent would have to infer.

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 line 'Without id, returns top 20' implies the two usage modes (all tickers vs a single ticker), which is useful context. However, there is no explicit when-to-use guidance or naming of alternatives such as coinpaprika_coin for a specific coin's details, leaving routing to inference.

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