redmine_upload_file

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

With no annotations provided, the description must independently disclose behavioral details. It states that the tool returns an upload token and uploads to /uploads.json, but it does not address side effects, authentication requirements, file size limits, or error conditions. This leaves gaps in transparency.

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, well-structured sentence that front-loads the core action and purpose. Every part is relevant and there is no redundancy.

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 no output schema, the description adequately mentions the return value (upload token). It covers the main use cases and the API endpoint. However, it omits details like error handling or constraints, which would make it more complete for an agent.

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 clarifies that 'content_base64' holds binary content, but does not explain 'filename' or 'content_type' beyond what the schema types imply. The description adds some value but not enough to fully overcome the lack of schema descriptions.

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 ('upload binary content'), the target endpoint ('Redmine /uploads.json'), and the purpose ('return an upload token for later attachment'). It effectively distinguishes this tool from its siblings, which cover other Redmine operations.

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 when to use this tool (first step for uploading files intended for attachment) and mentions the subsequent use cases (issues, documents, wiki pages, project files). It does not explicitly state when not to use it or name alternatives, but the context is clear enough for an agent.

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