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

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes what the tool checks (three specific areas) and what it returns (diagnostic results with actionable messages), which is helpful. However, it doesn't disclose important behavioral traits like whether this is a read-only operation, whether it makes any changes to systems, authentication requirements, rate limits, or error handling. The description adds value but leaves significant behavioral gaps.

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 perfectly sized and front-loaded. The first sentence establishes the core purpose, the second specifies the three diagnostic checks, and the third describes the return format. Every sentence earns its place with no wasted words or redundant information.

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 complexity (6 parameters, connectivity diagnostics across multiple cloud platforms) and no annotations or output schema, the description is adequate but incomplete. It explains what the tool does and returns at a high level, but doesn't cover important contextual details like authentication requirements, whether it performs active probes or passive checks, error conditions, or the format of diagnostic results. For a diagnostic tool with no structured output documentation, more completeness would be helpful.

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?

With 83% schema description coverage, the schema already documents most parameters well. The description adds meaningful context by explaining the diagnostic scope (Vercel env vars, AWS Security Groups, API reachability) which helps understand what the parameters enable. It doesn't provide additional parameter-specific details beyond the schema, but the high schema coverage means less burden on the description. The description compensates adequately for the 17% coverage gap.

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 specific verb ('diagnose connectivity issues') and resources ('between a source service and a target resource'), distinguishing it from sibling tools like 'check_resource_limits' or 'get_correlated_logs'. It explicitly mentions what the tool checks (Vercel environment variables, AWS Security Group rules, external API reachability) and what it returns (diagnostic results with actionable messages).

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 provides clear context for when to use this tool: for diagnosing connectivity issues between services and resources. It doesn't explicitly state when NOT to use it or name alternatives among sibling tools, but the specificity of its purpose strongly implies it's for connectivity diagnostics rather than resource monitoring or log analysis.

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