git_clone

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only mentions the operation ('clone') and a constraint (destination within workspace), but fails to disclose typical behaviors such as whether it overwrites existing directories, requires network access or credentials, or what happens on failure. This is a significant gap for a filesystem-modifying operation.

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 two sentences with no redundant words. The core action and the key constraint are front-loaded. Every word earns its place, making it highly concise and well-structured.

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?

The tool is a standard git operation, and the description includes the critical workspace boundary constraint. However, with no annotations, no explicit output schema details, and no mention of side effects or error handling, it is only minimally complete. An agent might need to infer common clone behavior, but it is not entirely inadequate.

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 100% coverage, documenting both 'url' and 'destination' parameters with descriptions. The description adds the workspace boundary constraint relevant to 'destination', but otherwise does not enrich parameter semantics beyond the schema. Given the high schema coverage, a baseline score of 3 is appropriate.

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's function: 'Clone a remote repository into a local directory.' The verb 'clone' is specific and the resource is identified ('remote repository'), distinguishing it from other git tools like git_init or git_pull. The additional constraint about the workspace boundary adds useful scope.

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 clear context for when to use the tool: when you need to clone a remote repository locally. It does not explicitly name alternatives or provide exclusion criteria, but the purpose is clear enough that an agent can select it without confusion. The workspace boundary constraint also informs usage expectations.

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