Fork Repository

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

Annotations indicate the tool is not read-only, not idempotent, and not destructive, but the description adds no behavioral details (e.g., whether the fork is a complete copy, how permissions are handled, or what the response contains). The description is too brief to convey meaningful behavior.

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 extremely concise (one sentence), but at the expense of clarity and utility. While brevity is generally good, the statement is too minimal to add value beyond the tool name. It earns a 3 as borderline adequate.

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 8 parameters, no output schema, and no parameter descriptions, the description is severely incomplete. It fails to explain how to use any of the parameters, what the fork operation entails, or what results to expect. The tool requires a much more detailed description to be usable.

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 parameter coverage is 0%, yet the description does not explain any of the 8 parameters (e.g., project_id, namespace, visibility). The description is completely silent on how parameters affect the fork operation, forcing the agent to rely solely on schema structure without semantic hints.

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 ('fork') and the target resource ('existing project') and destination ('another namespace'). It distinguishes the tool's purpose from similar operations like creating a new repository, but does not explicitly contrast with sibling tools.

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 provides no guidance on when to use this tool versus alternatives such as gitlab_create_repository or gitlab_create_branch. No context about prerequisites, scenarios, or exclusions is given.

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