upload_file_to_itglue

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

With no annotations, the description carries the behavioral disclosure burden. It reveals session-authentication reliance, the error and fallback when no valid session exists, the support for any file type, and the JSON string return. It does not explicitly say whether an upload overwrites existing files, but 'upload a file' strongly implies an additive create operation.

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 tightly organized: a one-sentence purpose, a brief clarification of scope and file-type support, a session-caveat warning, and clearly labeled Args/Returns sections. There is no repetition or filler, and the most important information is front-loaded.

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?

The definition covers purpose, session prerequisites, error behavior, parameters, and return type. Combined with the available output schema, this is sufficient for an agent to invoke the tool correctly. It could add explicit guidance on file replacement behavior or differentiation from create_document, but those are optional refinements rather than missing essentials.

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 must compensate. It does: file_path is explained as 'local path to the file', filename is described as an override with a default to the original name, and organization_id is given a clear target meaning. This adds real semantic value beyond the bare schema titles.

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 opens with a specific verb and resource: 'Upload a file to IT Glue Documents (GlueFiles).' It further narrows the target to 'an organization's Documents section.' There is no sibling upload tool, so this is immediately distinguishable from document read/create/update/delete siblings.

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 clearly implies the tool is for uploading files into an organization's Documents, but it never explicitly states when to prefer this over create_document or other document-related siblings. It does provide a prerequisite caveat about the session capture script, but that is a precondition rather than a comparison with alternatives.

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