upload_group_wiki_attachment

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

With no annotations, the description must carry behavioral information, but it only states the action. It does not disclose whether the upload is idempotent, what happens if the file already exists, authentication requirements, or any 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 a single sentence, which is concise but lacks structure. It is not verbose, but it sacrifices necessary detail for brevity. The sentence earns its place but does not provide sufficient context.

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 the absence of an output schema and the complexity of uploading a file (handling base64 vs raw content, branch specification), the description is far from complete. It omits critical details like how content is encoded, response format, or error conditions.

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 four parameters with zero description coverage. The tool description does not explain the meaning or format of 'group_id', 'file_path', 'content', or 'branch', leaving an AI agent to infer their roles without guidance.

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 an attachment') and the target resource ('GitLab group wiki'), effectively distinguishing it from the sibling tool 'upload_project_wiki_attachment' by specifying 'group' rather than 'project'. However, it does not explicitly contrast the two, so it's not maximally clear.

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 usage guidance is provided. The description does not indicate when to use this tool vs alternatives, nor any prerequisites or restrictions such as file size limits, permissions, or required branch existence.

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