## What it does

The skill hands your agent Gemini's multimodal features. It transcribes audio with timestamps, identifies speakers and analyses music, walks through video with scene detection and time-aware questions, reads PDFs including tables, forms and charts, and generates or edits images from text prompts. Three Python scripts do the work — `gemini_batch_process.py`, `media_optimizer.py`, `document_converter.py` — called from Bash.

You need a `GEMINI_API_KEY`. The skill looks for it in the process environment first, then in `.env` at the project root, then in `.claude/.env`, `.claude/skills/.env` and `.claude/skills/ai-multimodal/.env`. Vertex AI works too, via `GEMINI_USE_VERTEX`, `VERTEX_PROJECT_ID` and `VERTEX_LOCATION`. Install the SDK with `pip install google-genai python-dotenv pillow`. No key, no run — check that before anything else.

Model choice matters. Segmentation and multi-video need Gemini 2.5+, object detection needs 2.0+, and image generation only runs on `gemini-2.5-flash-image`. Context reaches 2M tokens, but video caps at 6 hours in low resolution or 2 hours by default. Audio stops at 9.5 hours, PDFs at 1,000 pages, and files uploaded through the File API are deleted after 48 hours.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mrgoonie/claudekit-skills --skill ai-multimodal -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ai-multimodal/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ai-multimodal/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mrgoonie/claudekit-skills --skill ai-multimodal -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ai-multimodal/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mrgoonie/claudekit-skills --skill ai-multimodal -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ai-multimodal/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mrgoonie/claudekit-skills ai-multimodal
```

2. **Manually: put the files in place**
- File: `.github/skills/ai-multimodal/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mrgoonie/claudekit-skills --skill ai-multimodal -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mrgoonie/claudekit-skills --path .claude/skills/ai-multimodal
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ai-multimodal/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mrgoonie/claudekit-skills --skill ai-multimodal -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mrgoonie/claudekit-skills/tree/HEAD/.claude/skills/ai-multimodal/SKILL.md

## When to use it
- transcribe a long meeting recording with timestamps
- pull PDF tables into JSON
- read a UI screenshot and spot the error
- shrink a large video before sending it to a model
- generate an image from a text description

## Example prompts
- Transcribe `audio.mp3` with timestamps using `gemini_batch_process.py`
- Extract the tables from `document.pdf` as JSON
- Summarize `video.mp4` and mark the key moments by time
