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 does disclose that output is redacted, which signals careful secret-handling. However, it does not state whether the check is read-only (implied but unconfirmed), what error behavior occurs when hcloud is absent, whether network access is involved, or whether any state is modified.

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 and approximately 14 words, with the verb and subject front-loaded. Every word contributes meaning; there is no padding, redundancy, or tangential detail.

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 zero-parameter check tool, the description is nearly complete. It conveys the action, the target resource, and the redaction behavior. The only gap is the exact shape of the return value, but 'returns redacted output' provides sufficient agent guidance for a simple preflight check, and the absence of an output schema makes some ambiguity unavoidable.

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 is empty with zero parameters, so schema coverage is vacuously 100%. There are no parameters for the description to elaborate on, yielding the baseline score of 3. Nothing is missing because nothing exists to describe.

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 states a specific verb ('check') and a specific resource ('Huawei Cloud KooCLI hcloud is installed'), which clearly distinguishes it from sibling command-execution tools like huaweicloud_run_approved_command or huaweicloud_plan_cli_command. However, the output format (boolean, status message, version string?) is not specified, which leaves slight ambiguity about what 'check' produces.

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?

No explicit guidance is given for when to use this tool versus alternatives. While one can infer it is likely a preflight prerequisite to huaweicloud_plan_cli_command or huaweicloud_run_approved_command, that inference is not stated. The description lacks any 'use this when...' or contrast with sibling tools.

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