MCP cldkctl Server

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. The description only states this is an endpoint call without indicating whether it's a read or write operation, what permissions might be required, what format the response takes, or any rate limits or constraints. This leaves the agent with insufficient information about how the tool behaves.

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?

While the description is brief (one sentence), it's under-specified rather than appropriately concise. The single sentence 'Call the cldkctl_balance_detail endpoint' doesn't provide meaningful information and wastes the opportunity to explain the tool's purpose. This is conciseness at the expense of utility.

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?

For a tool with no annotations and no output schema, the description is completely inadequate. It doesn't explain what the tool does, when to use it, what behavior to expect, or what the response contains. Given the complexity implied by the sibling tools (which include various billing, project management, and resource operations), this description fails to provide the necessary context for an agent to use the tool effectively.

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 schema description coverage is 100% with a single parameter (project_id) clearly documented in the schema. The description adds no additional parameter information beyond what's already in the schema. According to the scoring rules, when schema coverage is high (>80%), the baseline score is 3 even with no parameter information in the description.

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 'Call the cldkctl_balance_detail endpoint' is a tautology that restates the tool name with minimal added meaning. While it indicates this is an API call, it doesn't specify what the tool actually does (e.g., retrieve balance details for a project). The name suggests it might provide balance information, but the description fails to clarify this purpose.

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. There are many sibling tools related to billing, projects, and other resources, but no indication of when this specific balance detail tool is appropriate versus other billing-related tools like cldkctl_billing_daily_cost or cldkctl_billing_history.

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