upload_group_wiki_attachment

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

With no annotations, the description must disclose behavioral traits but does not. It omits details like whether attachments overwrite existing ones, authentication needs, or side effects. A one-sentence description is insufficient.

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 very concise at one sentence, but for a tool with 5 parameters, it is under-specified. Conciseness is achieved at the expense of necessary detail.

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 5 parameters, no schema descriptions, no output schema, and the complexity of uploading an attachment with encoding and branch, the description is incomplete. It does not cover how parameters like 'file_path' or 'content' work or what the return value is.

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?

The input schema has 5 parameters with 0% description coverage, and the description provides no explanation for any parameter. Parameter names like 'content_encoding' (enum utf8/base64) remain ambiguous; the description adds no value beyond the schema.

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 verb 'upload' and the resource 'attachment to a GitLab group wiki', which distinguishes it from related tools like 'create_group_wiki_page' and 'upload_project_wiki_attachment'.

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 is provided on when to use this tool versus alternatives (e.g., 'upload_project_wiki_attachment'), nor any prerequisites or constraints such as required permissions or file size limits.

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