redmine_upload_file

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

There are no annotations, so the description bears the full burden of explaining behavior. It discloses that the tool performs a two-step workflow: uploading the file and returning a token for later use. It does not mention permissions, file size limits, or token expiration, but for a single-parameter upload tool the core behavior is adequately described.

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 two short, focused sentences with no filler. The main action is front-loaded, and the follow-up sentence explains the practical purpose of the upload token.

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 one fully documented parameter, the description covers what the tool does, what it returns ('upload token'), and how the result is used later. It does not detail the response format or error behavior, but no output schema exists and the provided guidance is sufficient for correct invocation.

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 100% and the single parameter 'file_path' is already documented as 'Absolute path to the file to upload.' The description adds no additional semantic detail beyond what the schema provides, so the 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 states a specific action ('Upload a file to Redmine'), a clear resource (file), and a distinctive outcome ('get an upload token'). This clearly separates it from siblings like redmine_add_attachments, which attach files to issues directly.

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 explains that the token can be used later to attach the file to an issue, which gives useful context for when this tool is the right choice: as a preliminary upload step rather than the final attachment step. It does not explicitly name alternatives, but the usage context is clear.

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