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

Annotations already declare non-destructive, idempotent, open-world behavior. The description adds important operational context beyond annotations: paid x402 pricing, the X-Bazaar-Key header requirement, the exact checks performed, and a sample report link. It still does not discuss rate limits or return shape in prose, but the sample link partially covers the latter.

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 compact and front-loads the paid access requirement, then the audit scope, then the sample resource. Every element supports selection or invocation.

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 one-parameter composite audit with no output schema, the description gives enough to invoke it: price, auth header, URL target context from schema, seven checks, and a sample report. Explicit sibling-suite routing and response structure are the main remaining gaps.

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% and the single parameter is already documented as 'Target HTTPS URL to audit.' The description does not add syntax, format, or validation details beyond the schema, so baseline 3 is appropriate.

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?

States a specific composite audit and enumerates the seven checks: CSP, CORS preflight, HTTP security headers, cookie flags, open-redirect, file-upload, and SSRF. The web application/browser hardening framing distinguishes it from sibling suite tools such as API/auth, cloud, and smart-contract suites.

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?

Use is implied by 'audit' and the target URL parameter, but the description does not explicitly say when to choose this suite over adjacent sibling suites or when not to use it. The free sample report helps evaluation but does not add routing guidance.

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