What this skill does
# Image Extend
Extends an image canvas by adding padding on all sides with a solid background color.
## Command
```bash
npx agent-media@latest image extend --in <path> --padding <pixels> --color <hex> [options]
```
## Inputs
| Option | Required | Description |
|--------|----------|-------------|
| `--in` | Yes | Input file path or URL |
| `--padding` | Yes | Padding size in pixels to add on all sides |
| `--color` | Yes | Background color for extended area (hex, e.g., "#FFFFFF"). Also flattens transparency. |
| `--dpi` | No | DPI/density for output image (default: 300) |
| `--out` | No | Output path, filename or directory (default: ./) |
## Output
Returns a JSON object with the extended image path:
```json
{
"ok": true,
"media_type": "image",
"action": "extend",
"provider": "local",
"output_path": "extended_123_abc.png",
"mime": "image/png",
"bytes": 234567
}
```
## Examples
Add white padding around an image:
```bash
npx agent-media@latest image extend --in photo.jpg --padding 50 --color "#FFFFFF"
```
Add colored border:
```bash
npx agent-media@latest image extend --in artwork.png --padding 100 --color "#E4ECF8"
```
Extend with custom DPI:
```bash
npx agent-media@latest image extend --in print-ready.jpg --padding 75 --color "#000000" --dpi 600
```
## Providers
This action uses local processing only:
- **local** - No API key required (uses Sharp)

watch
IncludedWatch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.
physical-ai-defect-image-generation
IncludedUse when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment.

accelint-react-best-practices
IncludedReact performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.
elevenlabs-agents
IncludedBuild conversational AI voice agents with ElevenLabs Platform using React, JavaScript, React Native, or Swift SDKs. Configure agents, tools (client/server/MCP), RAG knowledge bases, multi-voice, and Scribe real-time STT. Use when: building voice chat interfaces, implementing AI phone agents with Twilio, configuring agent workflows or tools, adding RAG knowledge bases, testing with CLI "agents as code", or troubleshooting deprecated @11labs packages, Android audio cutoff, CSP violations, dynamic variables, or WebRTC config.

humanizer
IncludedHumanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.
generating-mermaid-diagrams
IncludedSalesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid. DO NOT TRIGGER when: user wants PNG/SVG image output (use generating-visual-diagrams), or asks about non-Salesforce systems.
