Immowelt Real Estate Search

Search immowelt.at and immowelt.de real estate listings (apartments, houses) via HTML parsing. No browser needed. Search any Austrian or German location with...

Security Scan

The skill’s requirements, instructions, and included code are consistent with a straightforward HTML-scraping tool for Immowelt listings and do not ask for unrelated credentials or install remote code — however the provided script content appears truncated so the full runtime behavior could not be fully verified.

Purpose & Capability

Name/description (search immowelt listings) match the requested runtime: python3 and a Python script that issues HTTP requests and parses HTML/embedded JSON. No unrelated binaries or credentials are requested.

Instruction Scope

SKILL.md and the visible script only instruct fetching Immowelt pages and parsing listing data (search pages and expose pages). There are no instructions to read local files, environment secrets, or send data to external endpoints other than immowelt. The SKILL.md also documents CLI flags and polite rate-limiting.

Install Mechanism

No install spec; skill is instruction-only and ships a Python script. Nothing is downloaded from untrusted URLs or written to the system by an installer.

Credentials

The skill requests no environment variables or credentials. It only requires python3 and the requests library (not declared but documented), which is proportionate for an HTTP-scraping CLI.

Persistence & Privilege

The skill is not always-on and uses the platform default (agent-invocable). It does not request persistent privileges or system-wide configuration changes.

Assessment

This skill appears to be a straightforward scraper for immowelt.at/.de and does not request secrets or install remote code, which is good. Two important caveats before installing: (1) the script contents provided in the prompt appear truncated (the listing stops at "parser.add_argume…[truncated]") — you should review the full, untruncated script to confirm there are no hidden behaviors (exfiltration, unexpected network calls, or filesystem access) in the tail of the file. (2) Scraping remote sites can violate Terms of Service; keep request rates low, follow the site’s robots rules, and run the tool in an isolated environment first. Also ensure the requests Python package is available in your runtime. If you want higher assurance, provide the complete script for a full code review or run the script in a sandbox to observe its network calls.

Search and retrieve property listings from immowelt.at (Austria) and immowelt.de (Germany) via HTML parsing. No browser automation needed.

Prerequisites

Requires python3 with the requests library (pre-installed in most environments).

URL Filter Parameters

Immowelt uses URL query parameters for filtering:

• rmi — Min rooms
• cp — Page number

Notes

• Search returns ~32 listings per page
• Expose UUIDs look like: 0a848843-86ba-4093-bd93-166258e909f7

• The --min-rooms filter is applied server-side but may not always be exact
