proofpoint_smart_search_trace

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It explains what the tool does (traces messages, tracks delivery status and history), which is transparent about its read-only nature implicitly. However, it does not mention pagination, rate limits, or any constraints or side effects beyond the basic behavior. For a search-style tool, this is adequate but lacks depth.

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 only two sentences long and front-loaded with the primary action ('Trace messages through the Proofpoint mail flow'). Every sentence contributes meaningful information: the first states the core purpose, the second lists search dimensions and the outcome. There is no fluff or redundancy.

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 moderate complexity (9 optional parameters, no output schema, no annotations), the description covers the essential context: what is traced, how to search, and what information is tracked. The schema handles parameter details, and the description adds the 'mail flow' and 'processing history' context. It could benefit from noting that all parameters are optional or that at least one search criterion is needed, but it remains largely complete for a read-oriented search tool.

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 input schema has 100% coverage for all nine parameters, so the baseline for parameter semantics is 3. The description adds minimal value by listing some searchable fields (sender, recipient, subject, message ID) that map exactly to schema properties, but it does not explain combination logic, date range usage, or API syntax. It neither improves nor degrades the schema's clarity.

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 tool's function: tracing messages through Proofpoint mail flow and searching by sender, recipient, subject, or message ID. It uses a specific verb ('trace') and names the resource, which conveys the core purpose. However, it does not explicitly differentiate this from sibling tools like proofpoint_smart_search_get_message or proofpoint_events_list, so it misses the highest bar for sibling distinction.

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 the usage scenario: when you need to trace message delivery status and processing history. It provides context but no explicit guidance on when to use this tool versus alternatives, and it does not state any prerequisites or exclusions. Sibling tools like proofpoint_smart_search_get_message are not referenced, so the usage guidance is adequate but not explicit.

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