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

With no annotations, the description carries the full behavioral burden. It usefully discloses the cost model ('Free') and a disclaimer ('Signal only, not financial advice'), implying a read-only, non-destructive call. It omits auth requirements, rate limits, and the fact that the data is a limited sample rather than the full signal set.

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 with no filler, and the payload (what you get) is front-loaded right after the 'Free:' tag. Terms like 'band-dot count' are terse to the point of being cryptic, but the overall structure is tight.

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 zero-parameter, read-only tool with no output schema, the description compensates by listing the exact fields returned, which is the most useful thing it can do. It is nearly complete for the call itself, missing only the distinction between this sample and the full signal endpoints.

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 takes no parameters, so per the baseline this dimension is a 4. The description correctly adds no parameter guidance, and its enumeration of returned values is content description rather than parameter semantics.

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 names the specific contents returned: Stage 1 regime statuses, core WaveTrend 4h values for five named coins, and a band-dot count. That is a concrete verb-less but resource-specific purpose. It does not, however, explicitly distinguish itself from siblings like get_regime, get_band_dots, or get_full_signal, so it stops short of a 5.

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 only usage signal is the leading 'Free:', which hints the tool is a no-cost entry point versus paid siblings such as list_paid_endpoints. There is no explicit when-to-use, when-not-to-use, or named alternative (e.g. get_full_signal for the complete dataset), leaving selection largely to inference.

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