upload_markdown

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

No annotations are provided, so the description must carry the full behavioral burden, but it only states the action. It does not disclose side effects, response type, upload constraints, or permission requirements, which leaves an agent without a clear model of what the call will do or return.

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 short, front-loaded sentence with no filler; the verb and object appear immediately. However, the brevity is so severe that it omits behavioral context, so it is not fully 'appropriately sized' for a tool with no annotations or output schema.

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?

With only two well-schema'd parameters and a low-complexity operation, the minimum needed for invocation is mostly present. But the lack of any return-value or behavior hint matters because there is no output schema and no annotations, making the description adequate for selection but incomplete for understanding the full outcome.

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 schema covers 100% of the parameters with clear descriptions for project_id and file_path, so the baseline is 3. The description adds no extra parameter-level meaning, such as whether file_path is a local source path or a destination path in the repository.

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 names a concrete action ('Upload a file') and a target resource ('a GitLab project'), with an explicit purpose ('for use in markdown content'). It is distinguishable from file-commit tools like create_or_update_file or push_files, though it does not explicitly contrast them.

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 intended use is implied by 'for use in markdown content,' giving some context for when an agent would choose this tool. It provides no explicit when-to-use/when-not-to-use guidance or alternatives, and given the large set of sibling file and repository tools, routing is left largely to inference.

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