OpenLCA_List_System_Processes_Tool

Lists all system processes in OpenLCA for inventory analysis and modeling workflows. Connect to an OpenLCA IPC server to retrieve process data.

Instructions

List all system processes using OpenLCA.

Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action is to 'list all' but doesn't clarify if this is a read-only operation, what the output format might be, whether there are rate limits, or if authentication is required. This leaves significant gaps for a tool interacting with a server.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, direct sentence that efficiently conveys the core purpose without unnecessary words. It's front-loaded with the key action and resource, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of server interaction and lack of annotations or output schema, the description is insufficient. It doesn't address behavioral aspects like safety, response format, or error handling, which are critical for an agent to use this tool effectively in a real-world context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the single parameter 'serverUrl' well-documented in the schema. The description adds no additional parameter information beyond what the schema provides, so it meets the baseline for adequate coverage without compensating value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('List all') and resource ('system processes') with the tool context ('using OpenLCA'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'Search_Processes_Tool' or 'Search_Life_Cycle_Models_Tool', which might also involve process-related operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools or specify contexts where listing all system processes is preferred over searching or other operations, leaving the agent to infer usage from the tool name alone.

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