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

With no annotations, the description carries the full burden of behavioral disclosure. It does reveal that the tool produces a live computed signal, lists the calculations involved, and appears to mention pricing via 'x402 (USDC on Base).' However, the fragment 'Turns raw Price 0.01' is grammatically unclear, and the description does not explain return format, data source specifics, or whether any auth/credits are needed beyond the schema's wallet note.

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 and front-loads the core signal components, but the final sentence 'Turns raw Price 0.01 via x402 (USDC on Base)' is confusing and poorly structured. It may be intended as pricing information, but as written it undermines clarity without adding precise value.

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?

The tool has no output schema and no annotations, yet the description does not describe the return shape, structure, or units of the signal, and it omits explicit mention that this is a DEX volume product. Given many sibling tools and an optional wallet parameter, an agent may struggle to know what it will receive or how this tool differs from adjacent analytics 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?

Schema description coverage is 100% for the single optional wallet parameter, with detailed free-tier credit information already in the schema. The description adds no parameter-level meaning, but it does not need to because the schema is already self-sufficient.

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 a specific action and output: 'get live computed signal' with clear components like '30-period percentile rank, 4-period momentum, and a plain-language trend verdict.' It is more specific than a generic analytics tool, though it never explicitly mentions DEX volume, which is only present in the tool name, so it does not fully distinguish itself from the many processed_* 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?

There is no guidance on when to use this tool versus alternatives like processed_defi_health, processed_defi_fees_revenue, or processed_crypto_prices. The phrase 'Finance Signal Bundle' implies a category, but it does not state prerequisites, exclusions, or a selection condition relative to sibling tools.

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