Sell

Sell (Kleinanzeigen)

Drive the Kleinanzeigen post-ad flow end-to-end. Always echo German field values back in English so the user can verify before publishing — a critical UX point if the user doesn't read German fluently.

Prerequisites

• An items directory at ` (set during setup) — defaults to ~/projects/sell-bot/items/`. Created if missing.
• Playwright MCP (mcp__playwright__* tools) connected. The MCP browser shares your logged-in Kleinanzeigen session automatically — no separate login step needed.
• Photos ready (any folder, any filenames).
• A Kleinanzeigen account (DE-only marketplace). If you're not in Germany, this skill won't be useful as-is.

Configuration

Edit these defaults at the top of this file before first use:

ITEMS_DIR     : ~/projects/sell-bot/items
PHOTOS_DIR    : ~/projects/sell-bot/items/photos
DEFAULT_ZIP   : 

Flow

1. Gather item details

Ask for the following. Batch into 1–2 messages, don't interrogate one field at a time:

• Title (will be shown as-is; ≤65 chars)
• Asking price in EUR, and whether firm (Festpreis) or negotiable (VB)
• Condition — map to Kleinanzeigen values:
• new → Neu
• like-new → Sehr Gut
• good → Gut
• acceptable → In Ordnung
• Category path — 3 levels, real German names as they appear on the site (e.g. ["Elektronik", "PC-Zubehör & Software", "Tastatur & Maus"]). If unsure, propose a path and confirm.
• Description — either the user writes it, or draft one in German and translate it back for approval.
• Photo folder path + filenames — or offer to rename/renumber a folder like ~/Downloads/razer/.
• Shipping — default to pickup only (Nur Abholung) unless told otherwise.
• ZIP — default to DEFAULT_ZIP from configuration above.

2. Write current.yaml

Write (overwrite) /current.yaml using this shape:

title: "..."
price: 70
price_type: "fixed"  # or "negotiable"
condition: "like-new"

kleinanzeigen:
  category_path: ["Elektronik", "...", "..."]
  shipping: false
  location_zip: "10115"

description: |
  ...

photos:
  - "01.jpeg"
  - "02.jpeg"

Then copy the photos into / with the filenames listed above. Use cp — don't move, in case the user wants the originals.

3. Drive Kleinanzeigen via Playwright MCP

Navigate to https://www.kleinanzeigen.de/p-anzeige-aufgeben-schritt2.html and verify the user is logged in (h1 includes "Profil von"). If not, stop and tell them to log in first.

Fill fields via mcp__playwright__browser_evaluate using native setters so React state updates:

const set = (id, value) => {
  const el = document.getElementById(id);
  const proto = el.tagName === 'TEXTAREA' ? HTMLTextAreaElement.prototype : HTMLInputElement.prototype;
  Object.getOwnPropertyDescriptor(proto, 'value').set.call(el, value);
  el.dispatchEvent(new Event('input', { bubbles: true }));
  el.dispatchEvent(new Event('change', { bubbles: true }));
  el.dispatchEvent(new Event('blur', { bubbles: true }));
};
// IDs: ad-title, ad-price-amount, ad-zip-code, ad-description

Category picker (separate page):

1. Click the ` inside the Kategorie row ("Wähle deine Kategorie" / "Kategorie ändern") — navigates to /p-kategorie-aendern.html`
2. Click each breadcrumb level in order by matching a.textContent.trim() === name
3. Click the Weiter button (German for "Next") to return to the form

Condition combobox: find the button next to the "Zustand (optional)" label, click it, then click the li[role='option'] whose text matches the German condition label.

Price type combobox: click #ad-price-type, then pick the li[role='option'] with text Festpreis / VB / Zu verschenken.

Shipping: for pickup-only, check #ad-shipping-enabled-no.

Photos: click the button whose text matches /zieh deine fotos/i to trigger the file chooser, then use mcp__playwright__browser_file_upload with absolute paths.

Photo sandbox gotcha: the MCP playwright tool restricts file access to the current working directory's allowed roots. If you get "File access denied", stage photos into the project's .playwright-mcp/sell-photos/ subdir first and upload from there. Clean up after publish.

4. Verify and translate back

After all fields are set, read back the final state with browser_evaluate:

({
  title: document.getElementById('ad-title')?.value,
  price: document.getElementById('ad-price-amount')?.value,
  priceType: document.querySelector("input[name='priceType']")?.value,
  condition: document.querySelector("input[name*='condition']")?.value,
  zip: document.getElementById('ad-zip-code')?.value,
  city: document.getElementById('ad-city')?.value,
  descTail: document.getElementById('ad-description')?.value?.slice(-200),
  categoryId: document.querySelector("input[name='categoryId']")?.value,
})

Present a summary table with English translations of every German value, the full description translated, and confirmation that photos uploaded. Examples of German → English the user will see:

• Festpreis = fixed price, VB = negotiable
• Nur Abholung = pickup only, Versand möglich = shipping available
• Sehr Gut = like new, Gut = good, In Ordnung = acceptable
• Vorschau = preview, Anzeige aufgeben = publish

5. Hand off

Tell the user to review in the browser and click Vorschau (preview) or Anzeige aufgeben (publish) themselves. Do not click publish programmatically.

Known field mapping

| YAML | Form field | ID / Name | |---|---|---| | title | Titel | #ad-title | | price | Preis | #ad-price-amount | | price_type: fixed | Preistyp = Festpreis | #ad-price-type combobox | | price_type: negotiable | Preistyp = VB | #ad-price-type combobox | | condition | Zustand (optional) | combobox near "Zustand" label | | kleinanzeigen.category_path | Kategorie | separate picker page | | kleinanzeigen.shipping: false | Versand = Nur Abholung | #ad-shipping-enabled-no | | kleinanzeigen.location_zip | PLZ | #ad-zip-code | | description | Beschreibung | #ad-description | | photos | Fotos | file chooser on "Zieh deine Fotos hier rein" button |

Don'ts

• Don't click Anzeige aufgeben (publish) — always hand off
• Don't list to eBay — this skill is Kleinanzeigen-only
• Don't skip the English-translation summary if the user doesn't read German
• Don't leave photos in .playwright-mcp/sell-photos/ after publish
