Willhaben

Create and manage listings on Willhaben.at (Austrian marketplace). Use when the user wants to sell something, create a listing, or mentions Willhaben. Handles photo uploads, generates titles/descriptions/prices, and posts via browser automation.

Security Scan

The skill's instructions, files, and behavior are coherent with its stated purpose (creating Willhaben listings), but it has an implicit dependency on a browser profile with a logged-in Willhaben account and access to user image files that the metadata does not declare explicitly.

Purpose & Capability

The skill's name/description match the instructions: it automates creating Willhaben listings, performs market research, drafts text, and posts via browser automation. However, it implicitly requires a 'clawd' browser profile with a saved Willhaben login (i.e., account cookies/credentials) and local image file access — this credential-like requirement is not declared in the skill metadata.

Instruction Scope

SKILL.md stays within the listing/posting scope: it reads a local user-preferences.json in the skill folder, analyzes user-supplied photos, searches willhaben.at, generates title/description/price, and automates form entry and uploads. It does not instruct reading unrelated system files, arbitrary env vars, or sending data to unexpected external endpoints.

Install Mechanism

There is no install spec (instruction-only). No packages or remote downloads are required, which minimizes installation risk.

Credentials

No environment variables or explicit credentials are requested, but the runtime instructions require: (1) access to a clawd browser profile that contains a logged-in Willhaben session (effectively account credentials/cookies), and (2) access to local image file paths for uploads. Both are sensitive capabilities that should be acknowledged by the user even though they aren't declared as required env/config in metadata.

Persistence & Privilege

The skill does not request always:true, does not modify other skills, and only reads/writes its own config (user-preferences.json). Normal autonomous invocation is allowed (platform default).

Scan Findings in Context

[no_regex_findings] expected: Scanner found no regex matches because this is an instruction-only skill with no code files to analyze. That absence is expected but not evidence of safety — the SKILL.md is the primary surface to review.

Assessment

This skill appears to do what it says — post listings to Willhaben using browser automation — but before installing or enabling it, understand the practical implications: it expects a 'clawd' browser profile with your Willhaben login (cookies/session) and will need access to photos (local file paths) to upload. That means the skill will act using your account and uploaded images. If you plan to use it, consider: (1) create or use a dedicated Willhaben account if you don't want automation actions on your primary account; (2) review and edit config/user-preferences.json so defaults are safe; (3) only supply images you intend to publish and confirm every draft before posting; (4) enable or verify 2FA and check whether automation can handle it; (5) do not assume the skill will hide paid-upsell selections — the instructions say to skip them but you should verify before final publish. If you need the skill to avoid using your main account, ask the author to explicitly declare the login requirement in metadata and to document how credentials/profiles are used.

Willhaben Listing Creator

Create listings on Willhaben.at via browser automation.

First-Time Setup

Check if config/user-preferences.json exists in the skill folder.

• If missing → run setup flow (see references/SETUP.md)
• If exists → read preferences and apply to all listings

User preferences include: location, shipping, description style, pricing strategy, disclaimers.

Workflow

1. Receive Item Details

• User sends photos (via WhatsApp/chat)
• Optional: user provides details (condition, category, price range)

2. Market Research

Before suggesting a price, search Willhaben for similar/identical items:

• Search willhaben.at for the item
• Note price range of comparable listings
• Check sold prices if available
• Report findings to user:
  • Neupreis (new price)
  • Marktpreis (what similar items are listed for)
  • Empfohlener Preis (recommended selling price)

3. Generate Listing

• Analyze photos to understand the item
• Generate:
  • Title: Concise, searchable (German)
  • Description: SHORT and casual - real people don't write essays. 2-3 sentences max. Mention key facts only.
  • Price: Based on market research, suggest realistic price
  • Package size: Estimate weight category for shipping (3kg / 10kg / 31.5kg)
• Ask user:
  • Location (Bezirk) - if not in preferences
  • Any damage/issues to mention
  • If they want a more detailed description (default: no)
• Present draft for confirmation including package size estimate

Listing Summary Template

Show the user something like:

📝 Listing Draft

📦 Package: ~Xkg (selecting [size] package)

If package weight is unclear (e.g., unusual item), ask the user rather than guessing wrong.

4. Post to Willhaben

See detailed browser automation steps below.

Only add detail if user explicitly asks for it.

Language

All listings in German (Austrian market). Keep it natural, like a real person wrote it.

Troubleshooting

Category not selecting

Even if the category appears, you must click on the radio/option area to actually select it. The validation error "Kategorie muss gewählt werden" means it wasn't clicked.

Images not uploading

Use inputRef with the "Bild auswählen" button reference (e.g., inputRef=e12). Do NOT use selector: input[type="file"] - it doesn't work reliably on this site.

Element refs going stale

Always take a fresh snapshot before interacting. Refs change after page updates.

Login required

If not logged in, the profile should have saved credentials. If needed, navigate to login page or ask user to log in manually in the browser.
