simulate_po_event

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

With no annotations provided, the description carries the full transparency burden. It explicitly says 'read-only; no state change' and discloses exactly what is returned for each ERP system (e.g., 'SAP Advanced Event Mesh CloudEvents envelope', 'SuiteScript user-event callback', 'Business Events envelope'). It does not cover auth, error handling, or rate limits, but for a simulation tool it communicates the key safety and output behavior well.

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 concise and front-loaded with the main purpose. The bullet list for parameters is scannable, and the system-specific details are useful. It could be slightly tightened, but every sentence contributes meaningful 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 moderate complexity and existing output schema, the description covers purpose, parameters, system-specific behavior, and use case. It is missing guidance on prerequisites like the active_system dependency and possible error/failure scenarios, but overall it is complete enough for an agent to understand and invoke the 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?

Schema description coverage is 0%, so the description is the only source of parameter meaning. It explains po_id with an example ('corpus PO id, e.g. "PO-8801"') and event_type with allowed-looking examples ('e.g. "Created" | "Changed"'), adding critical semantic value beyond the bare schema.

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 'Synthesize an inbound ERP change event for the given PO', which is a specific verb+resource combination. It distinguishes itself from sibling tools (get_, stage_, approve, etc.) by focusing on simulation/event synthesis rather than data retrieval or state-changing actions, and reinforces this with 'read-only; no state change'.

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?

It provides an explicit use case: 'Use it to exercise event-driven wiring.' It also explains system-specific behavior under SAP, NetSuite, and Dynamics 365, giving context for when it applies. However, it does not explicitly mention prerequisites like calling active_system or name alternative tools for different needs.

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