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

Annotations readOnlyHint=true are consistent with the description calling it an 'inspection station' that runs an audit and returns results. The description adds value by detailing what the report contains (evidence, remediation, certificate, next step) and clarifying it does not create a paid offer. No contradictions.

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 moderately concise, front-loading the main purpose and then listing outputs and usage notes. Some information could be streamlined, but it remains clear and contains no wasted sentences.

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 tool's simplicity (single required parameter, no output schema), the description adequately covers inputs, outputs, and usage constraints. It mentions out-of-scope items and connects to sibling tools audit_mcp and get_pricing, making it complete for an agent to invoke correctly.

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 sole parameter 'url' is fully described in the input schema with a clear description including 'ideally your own'. The overall description reinforces the parameter's purpose. Schema coverage is 100%, so the baseline is 3; the description adds helpful context beyond the schema.

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 it produces a complete MCP Full Readiness Report for one server, listing specific outputs like evidence, remediation, and signed certificate. It distinguishes itself from the sibling 'audit_mcp' by noting it runs the same audit but returns more comprehensive results.

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?

The description advises 'Use it as directory pre-flight' and 'Best run against YOUR OWN server.' It notes that legal/account requirements are out of scope and that it is free. It provides context for when to use, but could be more explicit about when not to use or about alternatives beyond audit_mcp.

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