Description
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.
Usage Guidance
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.
Capability Analysis
Type: OpenClaw Skill Name: wienerlinien Version: 1.0.0 The skill bundle is benign. All files consistently interact with the official Wiener Linien Open Data API (`https://www.wienerlinien.at/ogd_realtime`) and its associated CSV data. The shell scripts (`departures.sh`, `disruptions.sh`, `elevators.sh`, `search-stop.sh`) use `curl` to fetch data and `jq` (or `grep` for CSV) to parse and display it, without any signs of malicious execution, data exfiltration, persistence, or prompt injection attempts against the agent. The content is clearly aligned with its stated purpose of providing public transport information.
Capability Assessment
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.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install wienerlinien
  3. After installation, invoke the skill by name or use /wienerlinien
  4. Provide required inputs per the skill's parameter spec and get structured output
