Device Assistant

Personal device and appliance manager with error code lookup and troubleshooting. Tracks all your devices (appliances, electronics, software) with model numbers, manuals, and warranty info. When something breaks, tell it the error code and get instant solutions. Use when: device shows error, need manual, warranty check, adding new device, maintenance reminder. Triggers: /device, /geräte, 'mein Geschirrspüler', 'Fehler E24', 'Fehlermeldung', device problems, appliance issues.

Security Scan

The skill's code, runtime instructions, and requirements are consistent with a local device/appliance manager — nothing requests unrelated credentials or surprising system access.

Purpose & Capability

Name/description match the actual behavior: tracking devices in local JSON files, error-code lookup, manuals, warranty reminders. Required binaries (jq, curl) are reasonable for JSON manipulation and optional web lookups.

Instruction Scope

SKILL.md and handler.sh stay within the described scope (read/write JSON under $WORKSPACE/memory/device-assistant, lookup error codes, build search URLs). Note: the script constructs Google search URLs and may fetch external pages (curl) for manuals/searches — this is expected for error/manual lookup but means the skill may contact external websites when performing lookups or when following a user-provided manual/support URL.

Install Mechanism

No install specification — instruction-only with a bundled shell handler. No remote installers or archive downloads; nothing is fetched during install.

Credentials

No environment variables, credentials, or config paths required. The script uses only the provided $WORKSPACE directory for data storage; this is proportionate to the described functionality.

Persistence & Privilege

always:false and no special privileges requested. The skill stores data in its own workspace path and does not attempt to modify other skills or system-wide settings.

Assessment

This skill appears coherent with its description and stores data locally under $WORKSPACE/memory/device-assistant. Before installing, decide where you want the WORKSPACE to live (ensure it's a safe directory), and be aware that lookup/manual commands can fetch external URLs (the script builds Google search links and may call curl). Do not add manual/support URLs that contain sensitive tokens or credentials. If you need stricter privacy, run the handler in a restricted environment or inspect/disable network calls in scripts before use.

Error Code Lookup

The skill searches for error codes using:

1. Built-in database for common manufacturers
2. Web search for specific model + error code
3. Manual extraction if manual URL is stored

Common Error Code Patterns

Manufacturer	Pattern	Example
Siemens/Bosch	E + number	E24, E15
Miele	F + number	F11, F53
AEG	E + number	E10, E20
Samsung	Letters + numbers	UE, OE, LE
LG	Letters	OE, IE, PE
