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

With no annotations, the description carries the burden. It does disclose the one-time fee and price (0.05 via x402 on Base), which is important. However, it doesn't explain the payment flow, what happens without a wallet, or whether the fee is mandatory, leaving ambiguity.

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 a run-on sentence that mixes product contents with pricing, contains a typo ('an Price'), and is not well-structured. It could be split into clearer sentences for better readability.

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 description lists the report contents well, but for a paid tool with a single optional wallet parameter, it doesn't explain how payment is collected or what happens if no wallet is provided. The output schema is absent, so more operational detail would be expected.

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 coverage is 100% for the single optional wallet parameter, so the baseline is 3. The description adds no extra meaning about the parameter beyond what the schema already says about the X-Wallet free tier.

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 provides a live computed signal and a full research pack for a stock, listing specific contents (quotes, technical indicators, short interest, options chain). It distinguishes from macro-oriented sibling tools by focusing on individual stocks, though it doesn't explicitly name alternatives.

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 explicit guidance is given on when to use this tool versus the many sibling signal_* tools. The phrase 'full research pack on a stock' implies a use case, but there are no exclusions, prerequisites, or alternative tool mentions.

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