+
+# Image SEO
+
+Audit and fix image SEO issues in a project. Scans source code for `<img>` tags missing alt text, generates AI-powered alt text and keywords using the tinify-ai MCP server, and applies fixes to the codebase.
+
+## Pre-flight
+
+1. Call the `status` tool to check available credits (each image costs 4 credits: 3 base + 1 for SEO tag generation)
+2. Warn if credits are insufficient for the estimated number of images
+
+## Scan
+
+Find all images in source code that need SEO attention:
+
+1. Use Grep to find `<img` tags across the project:
+   - HTML: `*.html`
+   - React/Next.js: `*.tsx`, `*.jsx`
+   - Vue: `*.vue`
+   - Svelte: `*.svelte`
+   - Astro: `*.astro`
+
+2. From those matches, identify images with issues:
+   - Missing `alt` attribute entirely
+   - Empty `alt=""` on non-decorative images
+   - Generic alt text like `alt="image"`, `alt="photo"`, `alt="untitled"`
+   - Non-descriptive filenames like `IMG_4532.jpg`, `Screenshot 2024-01-15.png`
+
+3. Present the findings to the user before making changes:
+   - "Found X images missing alt text in Y files. Proceed?"
+
+## Generate Metadata
+
+For each image needing alt text, call `optimize_image` with SEO enabled:
+
+```
+optimize_image({
+  input: "/absolute/path/to/the/image.jpg",
+  output_seo_tag_gen: true
+})
+```
+
+The tool returns:
+- `seo_alt_text` — Descriptive alt text for the image
+- `seo_keywords` — Array of relevant keywords
+- `seo_filename` — SEO-friendly filename slug (without extension)
+
+## Apply Fixes
+
+1. Use Edit to insert the generated `seo_alt_text` into the source code:
+   - `<img src="hero.jpg">` → `<img src="hero.jpg" alt="Sunset over California beach with golden waves">`
+   - `<img src="hero.jpg" alt="">` → `<img src="hero.jpg" alt="Sunset over California beach with golden waves">`
+
+2. If the filename is non-descriptive (e.g., `IMG_4532.jpg`), suggest renaming:
+   - Show: `IMG_4532.jpg` → `sunset-california-beach.jpg` (from `seo_filename`)
+   - Only suggest — do not auto-rename without user approval (renaming may break other references)
+
+## Error Handling
+
+- If `optimize_image` fails with insufficient credits: stop, report progress, suggest `upgrade`
+- If an image file cannot be found at the path referenced in code: skip and note in report
+
+## Report
+
+Present a summary of changes:
+
+| File | Image | Alt Text Added | Filename Suggestion |
+|------|-------|----------------|---------------------|
+| `src/pages/index.tsx` | `hero.jpg` | "Sunset over California beach..." | — |
+| `src/pages/about.tsx` | `IMG_4532.jpg` | "Team meeting in modern office" | `team-meeting-office.jpg` |
+
+## Scope
+
+This skill handles image alt text and metadata only. It does NOT handle:
+- Page title tags or meta descriptions
+- Structured data / JSON-LD
+- Sitemap generation
+- Other non-image SEO concerns
