Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

nano-banana-ppt CLAUDE.md scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Nano Banana PPT is a multi-agent pipeline that converts documents (Markdown, PDF, text) into professional PowerPoint presentations using Google Gemini (via OpenAI-compatible API). It is designed to be invoked as a Skill from AI agents (Cursor, Claude Code).

Environment Setup

Install dependencies:

pip install openai python-pptx pillow pymupdf requests python-dotenv matplotlib

Configure API keys in .env (auto-discovered at project root or ~/.cursor/skills/nano-banana-ppt/.env):

OPENAI_API_KEY=sk-...
OPENAI_API_BASE=https://your-proxy/v1

GOOGLE_API_KEY is also accepted as a fallback for OPENAI_API_KEY.

CLI Commands

The module must be invoked from the parent directory of nano-banana-ppt/ (i.e., the directory containing tools/), since main.py uses sys.path.insert to resolve tools.nano_banana_ppt.*.

# Phase 1a: Generate content outline (saves content_plan.md)
python3 -m tools.nano_banana_ppt.main plan-content <content_file> [template_file] [logo_file] [output_name] [--pages N]

# Phase 1b: Generate visual plan (saves visual_plan.md / master_plan.md)
python3 -m tools.nano_banana_ppt.main plan-visual <project_dir> [--style <style_name>]

# Phase 1 shortcut (runs both 1a + 1b):
python3 -m tools.nano_banana_ppt.main plan <content_file> [template_file] [logo_file] [output_name] [--style <style_name>] [--pages N]

# Optional: text-only prototype PPTX (no image generation)
python3 -m tools.nano_banana_ppt.main prototype <project_dir_or_plan_md> [output_name] [--slides 1 2]

# Phase 2: Generate images + assemble PPTX
python3 -m tools.nano_banana_ppt.main execute <project_dir_or_plan_md> [output_name] [--resolution 1K|2K|4K] [--slides 3 5 7]

# Upscale existing slides
python3 -m tools.nano_banana_ppt.main upscale <project_dir> [--resolution 4K] [--slides 1 3 5]

# Legacy one-shot (non-interactive)
python3 -m tools.nano_banana_ppt.main auto <content_file> [template_file] [logo_file] [output_name]

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.
