devicelens_check_windows_updates

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

The description discloses that the tool does not download or install updates, which is crucial behavioral context not fully captured by annotations (readOnlyHint, idempotentHint, destructiveHint). This adds transparency beyond the structured fields.

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 a single, concise sentence that conveys the essential purpose and behavior without any extraneous information. Every word earns its place.

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?

Given the tool has no parameters and an existing output schema, the description is sufficient. It clearly states the scope (Windows, .NET, security updates) and non-installation behavior, which is adequate for an AI agent to select and invoke the tool correctly.

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 tool has no parameters, so the input schema is empty. The description does not need to add parameter information. The baseline for 0 parameters is 4, which is appropriate.

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 clearly states the tool's function: searching for pending Windows, .NET, and security software updates. It explicitly mentions it does not download or install, which distinguishes it from update installation tools. The sibling includes devicelens_check_driver_updates, indicating a clear differentiation between OS/security updates and driver updates.

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 does not explicitly provide usage guidelines or alternatives. It implies the tool is for checking updates without installing, but there is no guidance on when to use this versus other tools like devicelens_check_driver_updates. However, the sibling names offer implicit context.

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