Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds value by detailing the scope of the audit (specific on-page elements) and the grade output, which goes beyond the annotations' safety profile.
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 two sentences long, front-loaded with the tool's purpose and a list of checks, then the output format. No wasted words; every sentence contributes meaning.
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 simple tool with one parameter and no output schema, the description adequately explains what is checked and what is returned (A-F grade). It could elaborate on the return format, but it is sufficient for an AI agent to understand the tool's function.
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% with one parameter ('url') described as 'Full https URL to check'. The description reiterates this without adding new semantic detail, so baseline score 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?
The description clearly identifies the tool as an on-page SEO audit for a URL, listing specific elements checked (title, meta description, H1, etc.) and the return of an A-F grade. This specificity distinguishes it from sibling tools like check_security_headers or check_ssl.
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 implies use for on-page SEO auditing but does not explicitly state when to use or avoid this tool versus siblings. No guidance on alternatives or prerequisites is provided, but the context is clear enough.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct aspect of website analysis: AI visibility, email security, exposed files, security headers, SEO, SSL, and a general scan. No two tools overlap in purpose, making it easy for an agent to select the right one.
Six of seven tools follow the 'check_<subject>' pattern, which is clear and consistent. The outlier 'scan_website' breaks the pattern but is still understandable. Overall, naming is predictable with a minor deviation.
Seven tools is an appropriate number for a website scanning/analysis server. It covers key areas (security, SEO, AI visibility) without being overwhelming. Each tool earns its place by addressing a specific need.
The tool surface covers major website concerns: security (headers, SSL, exposed files, email), SEO, and AI visibility. The general 'scan_website' tool likely fills gaps like performance and secrets. Missing some niche checks (e.g., accessibility), but the core is well-covered.
