typst-test-slide
This skill should be used when the user asks to 'test a slide', 'isolate a slide', 'debug a slide', 'preview a single slide', 'test this slide', 'render one slide', or when you need to visually verify a single Typst slide from a presentation in isolation. Provides the exact file setup pattern to avoid access-denied and import errors.
What this skill does
# Typst Test Slide - Isolate and Render a Single Slide
Renders a single Typst slide in isolation for debugging or visual verification. This is a recipe, not a workflow.
## Why This Exists
Typst cannot access files outside its project root. Creating test files in `/tmp/` causes "access denied" on every `#import` and `#image()` call. This skill provides the correct pattern.
## Common Errors This Prevents
| Error | Cause | Fix |
|-------|-------|-----|
| `access denied` on `#import "../templates/theme.typ"` | Test file is in `/tmp/` (outside project root) | Put test file in `output/` inside the project |
| `access denied` on `#image(...)` | Image path resolves outside project root | Use `../assets/` from `output/` directory |
| `file not found` on `#import "../../templates/theme.typ"` | Wrong relative depth (used sub-slide depth instead of `output/` depth) | `output/` is one level deep: use `../templates/`, not `../../templates/` |
| Slides don't render (just text) | Missing `#show: university-theme.with(...)` preamble | Include the full preamble (see template below) |
## The Pattern
### 1. Create the test file in `output/`
```bash
cat > output/test-slide.typ << 'EOF'
#import "../templates/theme.typ": *
#show: university-theme.with(
aspect-ratio: "16-9",
config-info(
title: [Test],
author: [Test],
date: datetime.today(),
institution: [UVA],
logo: image("../assets/LawP_horizontal_short_4c_RGB.png"),
),
)
#slide[
// paste slide content here
]
EOF
```
### 2. Compile with `--root .` from project root
```bash
tinymist compile --root . output/test-slide.typ /tmp/test-slide.png --ppi 144
```
The `--root .` flag tells Typst that the project root is the current directory, so `../templates/` from `output/` resolves correctly.
### 3. Clean up
```bash
rm -f output/test-slide.typ
```
## Key Rules
- **Always create in `output/`**, never `/tmp/` or any directory outside the project root.
- **Always compile with `--root .`** from the project root directory.
- **Paths from `output/` go up one level**: `../templates/`, `../assets/`.
- **Paths from `slides/XX-topic/` go up two levels**: `../../templates/`, `../../assets/` -- do not confuse these depths.
- **Delete the test file when done.** `output/` is gitignored but keeping test files around causes confusion.

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.
