Instructions

Initialize the repository path for future code analysis operations.

Args:
    path: Path to the repository root directory that contains the code to analyze

Implementation Reference

  • The handler function for the 'initialize_repository' tool. Decorated with @mcp.tool(), it initializes the repository by calling the server's initialize_repo method, checks for .gitignore, and returns a status message.
    @mcp.tool()
    async def initialize_repository(path: str) -> str:
        """Initialize the repository path for future code analysis operations.
        
        Args:
            path: Path to the repository root directory that contains the code to analyze
        """
        try:
            mcp.initialize_repo(path)
            gitignore_path = Path(path) / '.gitignore'
            gitignore_status = "Found .gitignore file" if gitignore_path.exists() else "No .gitignore file present"
            return f"Successfully initialized code repository at: {mcp.repo_path}\n{gitignore_status}"
        except ValueError as e:
            return f"Error initializing code repository: {str(e)}"
  • Helper method on the CodeAnalysisServer instance ('mcp') that performs validation of the repository path and initializes the analyzer and file reader objects. Called from the tool handler.
    def initialize_repo(self, path: str) -> None:
        """Initialize the repository path and analysis tools."""
        if not path or path in (".", "./"):
            raise ValueError("Repository path must be an absolute path")
            
        repo_path = Path(path).resolve()
        if not repo_path.is_absolute():
            raise ValueError(f"Repository path must be absolute, got: {repo_path}")
        if not repo_path.exists():
            raise ValueError(f"Repository path does not exist: {repo_path}")
        if not repo_path.is_dir():
            raise ValueError(f"Repository path is not a directory: {repo_path}")
        
        self.repo_path = repo_path
        self.analyzer = RepoStructureAnalyzer(self.repo_path)
        self.file_reader = FileReader(self.repo_path)
  • Docstring in the handler function describing the input parameter 'path' (str) and purpose, serving as input schema documentation.
    """Initialize the repository path for future code analysis operations.
    
    Args:
        path: Path to the repository root directory that contains the code to analyze
    """
  • The @mcp.tool() decorator registers the following function as an MCP tool named 'initialize_repository' (inferred from function name).
    @mcp.tool()
Behavior2/5

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 states the tool initializes a path for future operations, but doesn't explain what 'initialize' entails (e.g., does it cache data, set up configurations, or validate the path?). It also omits details like error handling, permissions needed, or side effects, leaving significant gaps for a tool with no annotation support.

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

Conciseness4/5

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

The description is appropriately sized and front-loaded: the first sentence states the core purpose, followed by a brief parameter explanation. There's no wasted text, and the structure is clear. However, it could be slightly more efficient by integrating the parameter info more seamlessly, preventing a perfect score.

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?

Given the complexity (a setup tool with no annotations, no output schema, and low schema coverage), the description is incomplete. It doesn't explain what happens after initialization (e.g., success/failure states, return values, or how it interacts with sibling tools like 'read_file'). For a tool that likely enables other operations, more context on its role and outcomes is needed.

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

Parameters3/5

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

The description adds some meaning beyond the input schema: it explains that 'path' is 'Path to the repository root directory that contains the code to analyze,' clarifying the parameter's purpose. However, with 0% schema description coverage and only one parameter, the baseline is 4 for zero parameters, but here it's reduced to 3 because the description doesn't fully compensate for the lack of schema details (e.g., format expectations like absolute vs. relative paths).

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 tool's purpose: 'Initialize the repository path for future code analysis operations.' It specifies the verb ('initialize') and resource ('repository path'), making the action explicit. However, it doesn't distinguish this from sibling tools like 'get_repo_info' or 'get_repo_structure', which prevents 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 minimal guidance: it implies this tool should be used before other code analysis operations. However, it doesn't specify when to use it versus alternatives (e.g., if 'get_repo_info' might also initialize a path), nor does it mention prerequisites or exclusions. This lack of explicit context limits its utility for an AI agent.

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