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

With no annotations, the description carries the behavioral transparency burden. It does disclose that the tool computes a live signal and names the output components, and it hints at payment via x402 on USDC/Base. But it does not explain authentication requirements, rate limits, possible side effects, or return shape, and the pricing sentence is ambiguous enough to add confusion rather than clarity.

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 short, but poorly structured: the opening 'Finance Signal Bundle - get live computed signal' is redundant, and the final sentence 'Turns raw Price 0.01 via x402 (USDC on Base)' is truncated or grammatically broken. Compactness is not enough when key phrases are unclear.

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 tool with no output schema, the description should fully explain what the signal means and how to use the tool. It names three output metrics and mentions x402 pricing, but it fails to clarify what resource 'pools' refers to, how payment binds to the optional wallet parameter, or how this tool differs from the large family of processed_* tools. Important context is missing.

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 single optional wallet parameter is already fully documented in the schema, which covers 100% of parameters. The description adds nothing about the wallet parameter or payment flow, so the baseline of 3 applies: the schema does the heavy lifting and the description neither helps nor hurts parameter understanding.

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 that the tool gets a live computed financial signal and lists concrete outputs: 30-period percentile rank, 4-period momentum, and a trend verdict. However, it never states what 'btc_pools' refers to or that this is specifically about BTC, and it is not differentiated from the many processed_btc_* or signal_* siblings. The garbled closing phrase 'Turns raw Price 0.01 via x402 (USDC on Base)' further muddies the core 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?

No guidance is given about when to use this tool versus alternatives such as processed_btc_onchain, processed_btc_detail, or signal_* tools. There are no exclusions, prerequisites, or use-case conditions, so an agent would have to guess which of many similar tools is appropriate.

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