Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00834 | $0.00834 |
| Opus 5 | $0.00417 | $0.00417 |
| Sonnet 5 | $0.00167 | $0.00167 |
| Haiku 4.5 | $0.00083 | $0.00083 |
Grade A, and why
kleinanzeigen-reader CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Auto-load instructions for Claude Code
When this repo is in context, Claude should:
- Always read
SKILL.mdfirst before responding to any Kleinanzeigen-related request - Use
scripts/extract.pyfor single listings — do not rewrite extraction logic inline - Use
scripts/compare.pyfor 2+ listings - Load the relevant category reference from
references/categories/based on listing type - Never hardcode credentials — fetch URLs with the curl command in SKILL.md
Quick command reference
# Fetch a listing

Key data sources inside Kleinanzeigen HTML
| Source | Where | What it contains |
|---|---|---|
| JSON-LD | <script type="application/ld+json"> |
Title, price, images |
ad_attributes |
GTM JS block | All vehicle/item attributes |
li field |
GTM JS block | 0=private, 1=dealer |
| DFP block | GTM JS block | Clean price, km, EZ values |
| Hidden JSON | page JSON | Exact lat/long, userSince, originalPrice, status |
Mobile API (RE): references/mobile-api.md maps the app's CAPI (endpoints, auth
scheme, hidden fields). Reference only — the shipping code reads the public web page.
Signals: kl_reader/signals.py = view counter, seller portfolio, status
(reserved/sold), native price reduction, and a local PriceTracker.
Authenticated mode: kl_reader/auth.py Session (bring-your-own-token) = 👀 views +
⭐ watchers for any ad, full ad JSON, your own paused ads. Never reads browser creds from
disk; token via arg or KA_BEARER. Not live-validated — treat 401/403 as "refresh token".
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
