Implementation Reference

src/mcp_server_git/server.py:129-134 (handler)

The handler function that executes the git_init tool logic: initializes a new Git repository at the given repo_path using git.Repo.init.

def git_init(repo_path: str) -> str:
    try:
        repo = git.Repo.init(path=repo_path, mkdir=True)
        return f"Initialized empty Git repository in {repo.git_dir}"
    except Exception as e:
        return f"Error initializing repository: {str(e)}"

src/mcp_server_git/server.py:60-62 (schema)
Pydantic model defining the input schema for the git_init tool (requires repo_path: str).
```
class GitInit(BaseModel):
    repo_path: str
```
src/mcp_server_git/server.py:226-230 (registration)
Registration of the git_init tool in the server's list_tools() handler, specifying name, description, and input schema.
```
Tool(
    name=GitTools.INIT,
    description="Initialize a new Git repository",
    inputSchema=GitInit.schema(),
)
```

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Initialize' implies a write operation, it doesn't specify what exactly gets created (.git directory, default branch), whether it's idempotent, what happens if the path isn't empty, or what permissions are required. This leaves significant behavioral gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is perfectly concise - a single sentence that directly states the tool's purpose without any unnecessary words. It's front-loaded with the essential information and wastes no space.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool that creates a repository (a significant write operation) with no annotations, no output schema, and undocumented parameters, the description is insufficient. It doesn't cover behavioral aspects, parameter details, or expected outcomes, leaving the agent with inadequate context for proper usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage for the single parameter 'repo_path', the description provides no additional parameter information. It doesn't explain what 'repo_path' represents (e.g., absolute/relative path, must exist, must be empty), leaving the parameter's meaning and constraints undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Initialize') and resource ('new Git repository'), making the purpose immediately understandable. However, it doesn't differentiate this tool from its siblings (like git_clone or git_remote_add), which would require a perfect score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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. There's no mention of prerequisites (e.g., needing an empty directory), when not to use it (e.g., on existing repositories), or how it relates to sibling tools like git_clone.

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