+# Picture-it Skill
+
+CLI tool for AI image generation and editing using FAL AI. Chainable image operations with free local processing (crop, grade, grain, vignette) and paid AI operations.
+
+## Quick Start
+
+```bash
+# Load credentials first
+set -a && source ~/.config/opencode/.env && set +a
+
+# Ensure bun is in PATH
+export PATH="/home/kunthawat/snap/bun-js/87/.bun/bin:$PATH"
+
+# Basic generation
+picture-it generate --prompt "dark cosmic background" --size 1200x630 -o bg.png
+
+# AI edit
+picture-it edit -i photo.jpg --prompt "replace background" --model kontext -o edited.jpg
+
+# Thai text (requires patch)
+picture-it text -i bg.png --title "ทดสอบภาษาไทย" --font "Kanit" --font-size 64 -o out.png
+```
+
+## Commands
+
+| Command | Description | FAL? | Cost |
+|---|---|---|---|
+| `generate` | Text-to-image | Yes | $0.003–$0.25 |
+| `edit` | AI image editing | Yes | $0.02–$0.15 |
+| `remove-bg` | Background removal | Yes | free |
+| `replace-bg` | Remove + generate new bg | Yes | varies |
+| `crop` | Resize/crop | No | free |
+| `grade` | Color grading | No | free |
+| `grain` | Film grain | No | free |
+| `vignette` | Edge darkening | No | free |
+| `text` | Render text (Satori) | No | free |
+| `compose` | JSON overlay | No | free |
+| `template` | Built-in templates | No | free |
+| `pipeline` | Multi-step chain | — | varies |
+| `batch` | Multiple pipelines | — | varies |
+| `upscale` | AI upscale | Yes | varies |
+| `info` | Image analysis | No | free |
+
+## Model Selection
+
+| Task | Model | Cost |
+|---|---|---|
+| Fast draft | `flux-schnell` | $0.003 |
+| Quality hero | `flux-dev` | $0.03 |
+| Text in image | `recraft-v3` | $0.04 |
+| Quick edit | `reve-fast` | $0.02 |
+| Targeted edit | `kontext` | $0.04 |
+| Multi-image (≤10) | `seedream` | $0.04 |
+| Best preservation | `banana2` | $0.08 |
+| Premium realism | `banana-pro` | $0.15 |
+
+**Always plan before generating.** A 4-pass workflow is $0.10+.
+
+## Thai Font System
+
+picture-it uses Satori for text rendering. Thai fonts are NOT in the default `FONT_FILES` array.
+
+**Symptom:** Thai text shows as ▢ boxes.
+**Fix:**
+```bash
+bun ~/.hermes/skills/website-creator/creative/picture-it/scripts/thai-font-patch.ts --force
+```
+
+**This breaks after every `picture-it` update.** Re-run after updates.
+
+Thai fonts: `Kanit` (modern, bold), `Noto Sans Thai` (clean, official).
+
+## Setup
+
+1. **Install:** `bun install -g picture-it`
+2. **PATH:** Add `~/snap/bun-js/87/.bun/bin` to `$PATH`
+3. **FAL_KEY:** Store in `~/.config/opencode/.env` as `FAL_KEY=your_key`
+4. **Fonts:** `picture-it download-fonts`
+5. **Thai patch:** `bun ~/.hermes/skills/website-creator/creative/picture-it/scripts/thai-font-patch.ts`
+
+## Workflow Templates
+
+### Blog Hero (~$0.04)
+```
+1. generate flux-schnell ($0.003) → dark background
+2. edit seedream ($0.04) → place logo
+3. grade cinematic (free)
+4. vignette (free)
+```
+
+### Thai Text Hero (~$0.003)
+```
+1. Ensure patch applied
+2. generate flux-schnell ($0.003) → dark background
+3. text --font "Kanit" (free) → Thai title
+4. grade cinematic (free)
+```
+
+### Social Post (~$0.003)
+```
+1. generate flux-schnell ($0.003) → abstract background
+2. grade vibrant (free)
+```
+
+## Important Rules
+
+1. **Always load credentials before FAL commands:** `set -a && source ~/.config/opencode/.env && set +a`
+2. **Plan before generating** — ask about cost if workflow is complex
+3. **Re-patch after updates** — Thai fonts break after `bun install -g picture-it`
+4. **Use --model to override** — default models may not be cheapest for the task
+5. **Use free operations first** — crop, grade, vignette are free
+
+## Troubleshooting
+
+| Problem | Solution |
+|---|---|
+| "command not found" | Add bun to PATH: `export PATH="~/snap/bun-js/87/.bun/bin:$PATH"` |
+| Thai shows ▢ | Run: `bun ~/.hermes/skills/website-creator/creative/picture-it/scripts/thai-font-patch.ts --force` |
+| "No FAL API key" | Load credentials: `set -a && source ~/.config/opencode/.env && set +a` |
+| Fonts not found | Run: `picture-it download-fonts` |
