Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| devicelens_get_capabilitiesA | Describe DeviceLens safety boundaries, platform requirements, and available workflows. |
| devicelens_list_devicesB | List Windows devices as numbered physical groups instead of flattened Device Manager interfaces. |
| devicelens_explain_deviceB | Explain one grouped device and number its Windows child interfaces (for example, D03.1). |
| devicelens_open_device_propertiesA | Open Windows Properties for one exact interface without changing it. Pass an interface number such as D03.2 from devicelens_explain_device, or a full device instance ID. This opens only the exact resolved Properties dialog. It never clicks Disable, Uninstall, Update Driver, Roll Back Driver, or changes any setting. Opening the dialog is not permission for a later modifying action. |
| devicelens_prepare_identification_testA | Assess a user-operated identification test for one exact numbered interface. Pass an interface number such as D03.2 from devicelens_explain_device. The result states whether a manual test is appropriate and why risky devices are excluded. DeviceLens never disables or enables the device; the user must perform and reverse any Device Manager action themselves. |
| devicelens_capture_snapshotA | Save a local DeviceLens inventory snapshot; this never changes Windows devices or drivers. |
| devicelens_list_snapshotsA | List DeviceLens snapshots previously saved in the local application-data folder. |
| devicelens_compare_snapshotsA | Compare two saved inventories, or compare a saved snapshot with the current live device state. |
| devicelens_check_driver_updatesA | Search online for driver updates without downloading or installing anything. With a device name or D-number, checks that device's third-party driver packages. Without a device, checks up to max_catalog_checks distinct connected third-party packages and reports exactly how many eligible packages were skipped by that limit. |
| devicelens_check_windows_updatesA | Search for pending Windows, .NET, and security software updates without downloading or installing. |

TDQS
Scored across 10 tools
Each tool has a clearly distinct purpose, covering different aspects of device inventory and update checking without overlap.
All tools use a consistent snake_case pattern with the 'devicelens_' prefix and verb_noun structure.
With 10 tools, the server is well-scoped for its domain, neither too few nor too many.
The tool set covers the core workflows of inventory and update checking, though a delete_snapshot tool is missing for full lifecycle management.
