create_or_update_file

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

No annotations provided, so the description should carry the burden. It only states the basic functionality without disclosing behaviors like overwriting, permissions needed, or what happens if the file exists or not.

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 short (one sentence) and to the point. However, it sacrifices informativeness for brevity. A slightly longer description could add value without being verbose.

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 annotations, no output schema, and 6 undocumented parameters, this description is woefully incomplete. It fails to provide enough context for an agent to use the tool correctly.

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 coverage is 0%, yet the description adds no information about any of the 6 parameters (project_id, file_path, content, commit_message, branch, previous_path). The agent gets no semantic help beyond parameter names.

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 (create or update) and the resource (a single file in a GitLab project). It is specific but does not explicitly differentiate from sibling tools like push_files, which also deals with file content.

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 on when to use this tool vs alternatives (e.g., push_files, get_file_contents). No context about prerequisites or preferred scenarios.

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