pdf-to-markdown
Convert PDF to clean Markdown with image content described as text. Use when user wants to convert a PDF to markdown, extract content from PDF, or prepare PDF content for AI tools.
What this skill does
# PDF to Markdown Converter
Convert PDF files to clean, well-structured Markdown. Tables become markdown tables. Images and graphics are described as text (no image files generated).
## Quick Start
```bash
uv run skills/pdf-to-markdown/scripts/convert_to_markdown.py input.pdf
```
Output: `~/Desktop/{filename}.md`
## Options
| Flag | Description |
|------|-------------|
| `--no-llm` | Skip LLM processing (faster, images become `[Image]` placeholders) |
| `--force-ocr` | Force OCR on all pages (for scanned PDFs) |
| `--page-range "0,5-10"` | Process specific pages only |
## Common Use Cases
### Convert a PDF with default settings
```bash
uv run skills/pdf-to-markdown/scripts/convert_to_markdown.py ~/Documents/report.pdf
```
### Specify output location
```bash
uv run skills/pdf-to-markdown/scripts/convert_to_markdown.py report.pdf ~/Documents/report.md
```
### Fast conversion (no image descriptions)
```bash
uv run skills/pdf-to-markdown/scripts/convert_to_markdown.py --no-llm report.pdf
```
### Scanned PDF (force OCR)
```bash
uv run skills/pdf-to-markdown/scripts/convert_to_markdown.py --force-ocr scanned_doc.pdf
```
### Extract specific pages
```bash
uv run skills/pdf-to-markdown/scripts/convert_to_markdown.py --page-range "0-5" large_report.pdf
```
## Output
- Pure Markdown text (no embedded images)
- Tables converted to Markdown table format
- Images/charts described as text using LLM
- Clean formatting suitable for AI processing
## Requirements
- **GEMINI_API_KEY**: Required for LLM image descriptions (see SECRETS-SETUP.md)
- Use `--no-llm` flag if you don't have Gemini API access
## First Run Note
The first run downloads ML models (~1-2GB) which are cached at `~/.cache/marker/`. Subsequent runs are faster.
## Technical Details
Uses [Marker](https://github.com/VikParuchuri/marker) library:
- 31k+ GitHub stars
- Best-in-class PDF conversion accuracy
- Surya OCR for 90+ languages
- Gemini LLM integration for image understanding

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. Trigger keywords: defect image generation, dig workflow, dig pipeline, defect image detection workflow, aoi pipeline, aoi anomalygen, usd2roi anomalygen, day 0 pcba, day 1 pcba, day 1 real-photo alignment, day 1 manual roi, metal surface anomaly, glass defect, anomalygen finetune, setup_pcb, setup_metal, setup_glass, setup_pretrained, dig setup, dig datasets, dig pretrained checkpoint, dig image-edit endpoint.
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.
