Prerequisites

What you need before you start

01 · Claude Code + Python 3.10+

macOS, Linux, or Windows (WSL). Python is needed for the drawing-analyzer skill's single dependency (PyMuPDF).

02 · Gemini + Kling AI

Gemini for the isometric render (free tier covers iteration). Kling AI for the 10s walkthrough video (~€1.40 per clip). One render + one clip ≈ €2 per listing.

03 · Apollo (paid) + Prospeo + Instantly

Apollo for the company list — paid plan with API access required for the MCP. Prospeo enriches missing emails. Instantly runs the cold-email sequence.

04 · Six API keys, saved once

Anthropic, Gemini, Kling, Apollo, Prospeo, Instantly. All read from ~/.claude/.env, never pasted into prompts.

Step 01

Install Claude Code

Everything runs from Claude Code — the skills, the MCPs, the GTM prompts. If you don't have it yet, grab it now. Python 3.10+ is the only other runtime you need.

Step 02

Wire up your six API keys

Six accounts power the pipeline: Anthropic, Gemini, Kling, Apollo, Prospeo, Instantly. Save the keys once in ~/.claude/.env — every skill below sources them from the same file, so you never paste a key into a prompt.
