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

With no annotations, the description must carry the behavioral burden. It usefully discloses that output is a live computed signal with specific statistics and mentions a 0.01 USDC cost via x402, but it is truncated ('Turns raw s Price...'), omits what input data is consumed, whether any state changes occur, and what the response looks like.

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 not cleanly structured: it opens with a label and colon, then an incomplete sentence ('Turns raw s Price 0.01 via x402...') that appears cut off. The useful computation details are present but the broken phrasing wastes the compact space.

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 large sibling list, no output schema, and no annotations, this description is incomplete. It does not state the domain (funding rates), response format, payment/auth flow beyond a garbled price note, or when to prefer it over related crypto signal tools.

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 only parameter, wallet, is already fully described in the schema (100% coverage), including free-tier credit details. The description adds no meaningful param semantics; the garbled pricing note is only loosely related. Baseline 3 is appropriate because the schema already handles the parameter.

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 says it 'get[s] live computed signal' and describes the analytics (30-period percentile rank, 4-period momentum, trend verdict), so the general purpose is identifiable. However, it never mentions funding rates and the closing 'Turns raw s Price 0.01 via x402' is truncated/garbled, so it does not clearly differentiate this from the many processed_crypto_* and signal_* siblings.

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 on when to use this tool instead of siblings such as processed_crypto_funding_rate, processed_crypto_prices, or processed_crypto_movers. The phrase 'Finance Signal Bundle' implies a category but provides no selection condition or exclusions.

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