gitlab_get_file

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

With no annotations, the description carries the burden of disclosure. It indicates a read operation but does not mention what happens if the file is not found, the response format, or any authentication requirements. It adds some context by specifying the ref types but lacks behavioral depth.

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, front-loaded sentence with no redundant or filler content. Every word contributes meaningful information.

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?

For a simple file-reading tool, the description covers the core action but omits important context like return value details and parameter meanings for project and path. Given no output schema and no annotations, it is adequate but incomplete for an agent to fully understand edge cases.

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 no descriptions for any parameters, and the description only clarifies 'ref' by mentioning branch, tag, or commit. It does not explain whether 'project' is an ID or name, or whether 'path' is repository-relative, leaving ambiguity for two of the three parameters.

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 tool reads one file from a GitLab repository at a branch, tag, or commit ref, with a specific verb and resource. It is easily distinguished from sibling tools that operate on projects, merge requests, or pipelines.

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 clearly conveys the tool's purpose, making it obvious when to use it (to read file contents) versus sibling tools. However, it does not explicitly mention alternatives or exclusion cases, though none are critical given the distinct functionality.

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