get_v1_kaspa_derivatives_fee_estimate

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

With no annotations provided, the description carries full burden for behavioral disclosure. It describes the data source (node estimator) and nature (informational research), but fails to mention key traits like whether it is read-only, data freshness, caching behavior, or any required permissions. It does not contradict any annotations because none exist.

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 concise, front-loading the core function ('Kaspa live fee market') in one sentence, followed by a disclaimer and metadata. The inclusion of 'Price: $0.03' and 'Category: kaspa' is slightly extraneous but does not significantly harm readability. It could be trimmed, but overall it is efficient.

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?

Given the tool's simplicity (no parameters, no output schema), the description provides moderate completeness. It indicates the tool returns feerate buckets but does not specify the exact structure (e.g., object with fields priority, normal, low). For a zero-parameter tool, this is adequate but not highly informative. An explicit format would improve completeness.

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 and schema coverage is trivially 100%. The description adds context by naming the output fields (priority/normal/low feerate buckets) and source (Toccata RPC), which goes beyond the empty schema. According to guidelines, 0 parameters baseline is 4.

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 retrieves live fee estimates (priority/normal/low) from Kaspa's node estimator (Toccata RPC). It specifies the source and scope, making the purpose clear. While it distinguishes from unrelated tools, it does not explicitly differentiate from sibling Kaspa fee tools like get_v1_kaspa_derivatives_fee_regime, which might have a similar purpose.

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 provides no guidance on when to use this tool vs alternatives, nor does it mention prerequisites or limitations. The disclaimer 'not investment advice' is not a usage guideline. Agents are left without context for appropriate invocation.

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