Wiener Linien

Vienna public transport (Wiener Linien) real-time data. Use when asking about departures, schedules, disruptions, elevator status, or directions in Vienna's public transport (U-Bahn, tram, bus, night bus). Queries stops, lines, and traffic info.

Security Scan

The skill's code and instructions align with its stated purpose (querying Wiener Linien real-time data); it only makes straightforward requests to wienerlinien.at and does not ask for credentials or perform suspicious actions.

Purpose & Capability

Name/description match the actual behavior: scripts and SKILL.md call Wiener Linien OGD realtime endpoints to fetch departures, disruptions, elevator info and stop CSVs. No unrelated services, credentials, or unrelated binaries are required by the functionality.

Instruction Scope

Runtime instructions and the included shell scripts only perform network requests to wienerlinien.at (monitor, trafficInfoList, newsList, and CSV of stops) and parse results with jq/grep/head. The scripts do not read arbitrary local files, access unrelated env vars, or forward data to third-party endpoints.

Install Mechanism

There is no install spec (instruction-only), which is low risk. Minor metadata mismatch: registry lists no required binaries, but README and scripts expect curl and jq (and search-stop.sh uses grep/head). This is an implementation detail to be aware of, not an active risk.

Credentials

The skill requests no environment variables, no credentials, and no config paths. All network calls are to the Wiener Linien open-data endpoints, consistent with the described purpose.

Persistence & Privilege

always is false and the skill does not attempt to modify agent/system configuration. It is user-invocable and may be invoked autonomously per platform defaults, which is expected for a utility skill.

Assessment

This skill appears coherent and benign: it fetches public Wiener Linien Open Data via HTTPS and parses it locally. Before installing, confirm you are comfortable allowing outbound network requests to wienerlinien.at and that curl and jq are available in the environment (search-stop.sh also uses grep/head). Note the registry lists no homepage and the owner is an ID only — if provenance matters, try to verify the author/source (e.g., a repo or publisher) before use. If you have strict security requirements, run the scripts in a sandboxed environment and inspect them yourself; any deviation such as calls to other domains or requests for credentials would be a red flag.

Finding Stop IDs

Stops are identified by RBL numbers (Rechnergestütztes Betriebsleitsystem). Use the reference data:

# Search stops by name
curl -s "https://www.wienerlinien.at/ogd_realtime/doku/ogd/wienerlinien-ogd-haltepunkte.csv" | grep -i "stephansplatz"

# Format: StopID;DIVA;StopText;Municipality;MunicipalityID;Longitude;Latitude

Common Stop IDs (RBL):

Stop	RBL IDs	Lines
Stephansplatz	252, 4116, 4119	U1, U3
Karlsplatz	143, 144, 4101, 4102	U1, U2, U4
Westbahnhof	1346, 1350, 1368	U3, U6
Praterstern	4205, 4210	U1, U2
Schwedenplatz	1489, 1490, 4103	U1, U4
Schottentor	40, 41, 4118	U2, Trams

Tips

1. Multiple platforms: A single station may have multiple RBL IDs (one per platform/direction). Query all for complete departures.

2. Real-time availability: Check realtimeSupported - some lines only have scheduled times.

3. Countdown vs timeReal: Use countdown for display, timeReal for precise timing.

4. Barrier-free routing: Filter by barrierFree: true for wheelchair users.

5. Find stop IDs: Search the CSV files by station name, then use the StopID as stopId parameter.
