utility_ssl_check

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

No annotations are provided, yet the description fails to disclose that the tool performs a network connection to the given host/port. This is a key behavioral aspect (dependency on internet, potential latency) not mentioned. The description only states the retrieval but not the underlying mechanism.

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 single, succinct sentence that front-loads the action and key details. Every word is necessary, with no fluff 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?

The tool has no output schema, and the description partially compensates by listing three return fields (expiration, issuer, subject). However, it omits details about error handling, timeouts, or response format, which would fully complete the context for an agent.

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 both parameters described. The description adds value by listing the certificate details returned, which is not in the schema. However, it does not add significant new meaning beyond the schema's parameter docs, 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?

The description uses the specific verb 'Retrieve' and identifies the resource 'SSL certificate details' with explicit examples (expiration, issuer, subject). It clearly distinguishes from sibling tools by specifying a unique function not covered by other utilities.

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 when-to-use or when-not-to-use guidance is given, but the sibling list contains no other SSL-related tools, so ambiguity is minimal. Lacks prerequisites like network access, but the tool's purpose is self-evident.

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