supplier_invoice_bulk_create

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

No annotations provided, so the description should fully disclose behavior. It only states 'uploading files' but does not explain what happens upon completion (e.g., returns a list of created invoice IDs), whether the operation is synchronous, or how invalid files are handled. The description is minimal and leaves many behavioral aspects unspecified.

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 sentence with no superfluous words. It is immediately clear, front-loaded with the action, and efficiently describes the core functionality.

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 simple parameter structure and lack of output schema, the description covers the basic action. However, it does not mention return values, error handling, or processing mode (synchronous/batch). For a tool with such low complexity, the description is acceptable but could be more informative.

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?

With 100% schema description coverage, the schema already explains the file_paths parameter clearly (absolute paths, accepted formats). The tool description adds no further semantic value beyond what the schema provides, so a baseline score of 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 clearly states the action (create) and resource (supplier invoices) and distinguishes it from other operations like viewing or managing individual invoices. The verb 'Create' and object 'supplier invoices' are specific, and 'uploading files from the filesystem' adds unique context versus other sibling tools.

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 on when to use this tool versus alternatives (e.g., single invoice creation, manual entry). There is no mention of prerequisites, batch processing behavior, or error scenarios. The description lacks any usage context or exclusions.

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