"""Example: Generating Proof-of-Concept exploit scripts.

Demonstrates how to use the PoCGenerator to create standalone
exploit scripts from attack results — useful for reproducing,
validating, and sharing vulnerability findings.  No API keys
required — this uses synthetic attack results.

What this example shows
-----------------------
  1. Creating AttackResult objects programmatically
  2. Generating a Python PoC script
  3. Generating a cURL PoC script
  4. Generating a Markdown reproduction guide
  5. Using ``generate_all()`` from a CampaignResult

Usage::

    uv run python examples/poc_generation_example.py
