file_converter_split_action

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

No annotations are provided, so the description must bear this burden. It discloses the output format (array of URLs) but does not mention behaviors such as whether the original PDF is modified, storage duration of URLs, file size limits, or required access permissions. This leaves some uncertainty about the tool's side effects.

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 extremely concise at two sentences, with no redundant or filler content. Each sentence serves a purpose: stating the action and specifying the return value.

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?

For a simple tool with two required parameters and no output schema, the description is mostly complete. It covers the core operation and output. Minor gaps remain: the nature of the returned URLs (temporary? accessible?) and any prerequisites are not mentioned, but the overall context is sufficient for an agent to understand the tool's role.

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 coverage is 100%, so parameters are already documented. The description adds no additional meaning beyond the schema; it does not explain the parameters further or provide usage context for input_file_url or output_variable_name.

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 specifies the action (Split a PDF into one file per page) and the output (array of individual page PDF URLs), distinguishing this tool from other file_converter actions like merge, convert, or optimize.

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 usage for splitting PDFs into separate pages but provides no explicit guidance on when to use this tool over alternatives like file_converter_merge_action or file_converter_ocr_action. No when-not-to-use or precondition details are given.

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