proofpoint_url_analyze

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 does state the returns, but it omits any information about side effects, safety, rate limits, or specific behavior beyond the return values. 'Analyze' implies a read operation, but that is not explicit.

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?

Two short sentences with the key action first ('Analyze a URL for threats') and the return values in the second. Every word contributes value, and there is no fluff or repetition.

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 description covers the purpose and the main returns, which is adequate for a simple single-parameter tool with no output schema. However, it lacks usage guidance, any mention of failure modes or edge cases, and does not contextualize the tool among its many siblings, leaving clear 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 'url' parameter is self-explanatory ('URL to analyze for threats'). The description adds nothing about format, encoding, or constraints on the parameter; it only clarifies the output, which is not parameter semantics. 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 'Analyze' with the resource 'URL', and clearly states the output (threat classification, risk score, campaigns). It is unambiguous about the core purpose, though it does not explicitly differentiate from sibling tools like proofpoint_url_decode, which also handles URLs.

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 guidance is provided on when to use this tool versus alternatives such as proofpoint_url_decode or other threat-analysis tools. The description does not mention any exclusions, prerequisites, or preference rules, leaving the agent without decision support.

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