Implementation Reference

  • Handler logic for the cosmosdb_container_list tool: retrieves the list of containers from the Cosmos DB database and extracts their names into a response dictionary.
    elif name == "cosmosdb_container_list":  # Renamed from table to container
        containers = list(database.list_containers())
        container_names = [c["id"] for c in containers]
        response = {"container_names": container_names}
  • Input schema definition for the cosmosdb_container_list tool, which optionally takes a database_name parameter.
    Tool(
        name="cosmosdb_container_list",  # Renamed from table to container
        description="List all Cosmos DB containers in a database",  # Updated description
        inputSchema={
            "type": "object",
            "properties": {
                "database_name": {

                }
            },
        },
    ),
  • The get_cosmosdb_tools function registers the cosmosdb_container_list tool by including it in the list returned for tool discovery.

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. It states the action but does not cover critical aspects like whether this is a read-only operation, potential rate limits, authentication needs, or the format of the returned list (e.g., pagination). This leaves significant gaps for an agent to understand the tool's behavior.

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 a single, clear sentence that efficiently conveys the core purpose without unnecessary words. It is front-loaded and appropriately sized for a simple list operation, making it easy for an agent to parse quickly.

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 lack of annotations and output schema, the description is incomplete. It does not address behavioral traits, return values, or usage context, which are essential for an agent to effectively select and invoke this tool in a real-world scenario with sibling alternatives available.

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?

Schema description coverage is 100%, with the single parameter 'database_name' fully documented in the schema as optional with a default. The description does not add any additional meaning beyond what the schema provides, such as examples or constraints, so it meets the baseline for adequate but not enhanced coverage.

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 ('List') and resource ('all Cosmos DB containers in a database'), making the purpose immediately understandable. However, it does not explicitly differentiate from sibling tools like 'cosmosdb_container_describe' or 'blob_container_list', which would require more specific scope or context.

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?

No guidance is provided on when to use this tool versus alternatives such as 'cosmosdb_container_describe' for detailed container info or 'blob_container_list' for blob storage. The description lacks context on prerequisites, exclusions, or typical scenarios for invocation.

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