| description | Full-stack content creation pipeline: idea or reference to published blog post, audio narration, video, and social media distribution. Orchestrates research, reference extraction, storytelling, AI visual assets (Nano Banana, Veo 3.1), TTS audio (Voicebox, kokoro-tts, Edge TTS), Remotion video, and social copy into a complete content package. Use when: (1) creating a blog post, case study, or writing entry, (2) turning an idea or experience into structured narrative, (3) using a reference post/video (X, LinkedIn, YouTube) as inspiration, (4) generating visual content (AI images, clips, screenshots, GIFs), (5) generating audio narration for posts, (6) creating social media content (X threads, Instagram carousels) from long-form writing, (7) packaging and distributing content across platforms. Triggers on 'new post', 'blog post', 'case study', 'content creation', 'write about', 'content pipeline', 'social content from post', 'use this as reference', 'generate audio', 'tts', 'narration'. |
Content Creation Pipeline
Eight-phase workflow: reference/idea → published multimedia content package with social distribution.
REFERENCE (optional) → RESEARCH → NARRATIVE → VISUAL ASSETS → AUDIO → VIDEO → SOCIAL → DEPLOY
Setup & Onboarding
Before using the pipeline, the agent MUST check which tools are available and guide the user through setup for any missing ones. Run the checklist below at the start of every content creation session.
Prerequisite Check (run this first)
echo "=== Required ==="
which yt-dlp && echo "✓ yt-dlp" || echo "✗ yt-dlp — needed for video download"
which ffmpeg && echo "✓ ffmpeg" || echo "✗ ffmpeg — needed for video processing"

Agent Behavior
When the skill is triggered, the agent should:
- Run the prerequisite check silently (don't dump output unless something is missing)
- If critical tools are missing (yt-dlp, ffmpeg, GEMINI_API_KEY), tell the user what's needed and offer to install/configure:
- For CLI tools: offer the
brew install command
- For API keys: explain where to get them and how to set them
- For npm packages: offer to install in the current project
- If optional tools are missing, proceed without them and mention alternatives:
- No
agent-browser? Use FxTwitter API + yt-dlp for extraction
- No
FAL_KEY? Use @google/genai directly
- No
xurl? Generate the post copy for manual publishing
- Never fail silently — if an API call fails due to missing key, explain which key is needed and how to get it
- Adapt the pipeline to available tools — use the best available method, not the ideal one
Phase 0: Reference Extraction (when user provides a link)
When the user provides a URL to a post, video, or thread as creative reference, extract and analyze it before anything else. See references/x-content-extraction.md and references/reference-based-content-creation.md for full details.
Step 1: Extract content from the link
X/Twitter posts (fastest — no auth required):
TWEET_ID="2034332847893574080"
curl -s "https://api.fxtwitter.com/status/$TWEET_ID" | jq .
yt-dlp "https://x.com/user/status/$TWEET_ID" -o reference_video.mp4
curl -sL "https://d.fxtwitter.com/user/status/$TWEET_ID" -o reference_video.mp4
YouTube / other platforms:
yt-dlp "URL" -o reference_video.mp4
Any URL with agent-browser (screenshot + text extraction):
agent-browser open "URL" && agent-browser wait --load networkidle
agent-browser screenshot reference_screenshot.png --full
agent-browser get text body > reference_text.txt
Step 2: Analyze with Gemini (video understanding + style extraction)
Upload the downloaded video to Gemini for deep analysis:
import { GoogleGenAI } from "@google/genai";
const ai = new GoogleGenAI({ apiKey: process.env.GEMINI_API_KEY });
const file = await ai.files.upload({ file: "reference_video.mp4", config: { mimeType: "video/mp4" } });
const analysis = await ai.models.generateContent({
model: "gemini-2.5-flash",
contents: [
{ fileData: { fileUri: file.uri, mimeType: file.mimeType } },
{ text: `Analyze this video as a content creation reference. Extract:
1. Visual Style: color palette (hex values), lighting, camera angles, framing
2. Pacing: shot durations, rhythm, fast/slow sections with timestamps
3. Transitions: types used (cuts, fades, zooms) and when
4. Text Overlays: fonts, positioning, animation, timing
5. Structure: hook (first 3s), body, CTA placement
6. Audio: music style, SFX, voiceover style
7. Engagement Hooks: techniques for retention
Return as structured JSON.` },
],
});
For text/image posts, use Gemini or Claude directly on the extracted text + screenshot to analyze hook type, structure, messaging, and CTA pattern.
Step 3: Generate a style brief
The analysis produces a style brief that guides all downstream phases:
- Narrative phase: match hook type, structure, CTA pattern
- Visual phase: match color palette, typography, layout
- Video phase: match pacing, transitions, aspect ratio, duration
- Social phase: match platform conventions and engagement patterns
Multimodal Embedding (for similarity search)
Use Gemini Embedding 2 to find similar content in your library:
const embedding = await ai.models.embedContent({
model: "gemini-embedding-2-preview",
contents: [{ inlineData: { mimeType: "video/mp4", data: videoBase64 } }],
config: { outputDimensionality: 768 },
});
Supports text, images, video (up to 120s), audio (up to 80s), and PDFs in a single vector space.
Phase 1: Research
Gather evidence, capture production state, pull metrics. Never write without data.
Compounding skills: /deep-research, /agent-browser, /competitor-intel, curl/API data pulls.
Checklist:
Phase 2: Narrative
Structure using a proven framework. See references/storytelling.md for full guides.
| Content Type | Framework | Structure |
|---|
| Case study | PSI | Challenge → Solution → Quantified results |
| Industry highlight | ABT | Context AND, BUT challenge, THEREFORE outcome |
| Technical deep dive | 1-3-1 | One idea, three evidence points, one takeaway |
| Product launch | Pixar Spine | Once upon a time... Every day... Until one day... |
| Data story | Data Arc | Context → Tension → Resolution |
Blog Post Structure
frontmatter (title, summary, date, published, tags)
Hook (1-2 sentences — open loop or surprising claim)
Hero media (video or key image)
Numbers section (table with headline metrics)
Problem section + image
Solution section + image + progressive detail image
Evidence section + dashboard screenshots + data visualizations
Context section + variant screenshots
Practice section + animated GIF
Generalization section
Closing (memorable one-liner)
Rules: Lead with numbers. One image per ~300 words. Bold key terms on first use. 3-4 sentence paragraphs max. Use <video> for MP4,  for images/GIFs.
Output: MDX file at apps/chat/content/writing/{slug}.mdx.
Phase 3: Visual Assets
Compounding skills:
/agent-browser — production screenshots, UI workflows/pencil (MCP) — design social cards, diagrams, slides in .pen files
get_guidelines(topic) for design-system/landing-page/slides guidanceget_style_guide(tags) for visual consistencybatch_design for multi-element compositionsget_screenshot to export assets
/before-and-after — visual diffs for transformation stories/frontend-design — custom visual components/arcan-glass — BroomVA brand styling
AI-Generated Assets
See references/ai-video-generation.md for full API details, code examples, and Remotion integration patterns.
Image generation (Nano Banana / Gemini):
nano-banana "A hero image for {topic}, dark theme, glass effects, 1080x1080"
Video generation (Veo 3.1):
uvx mcp-veo3 --output-dir assets/ai-clips/
Multi-provider (fal.ai):
bun add @fal-ai/client
Preprocessing AI clips for Remotion (critical):
ffmpeg -i ai_clip.mp4 -c:v libx264 -crf 18 -movflags +faststart -r 30 processed.mp4
Manual Asset Pipeline
Image pipeline:
magick input.png -resize 1200x -quality 85 output-opt.png
magick f1.png f2.png f3.png -resize 1200x675! -set delay 200 -loop 0 flow.gif
mkdir -p apps/chat/public/images/writing/{slug}/
Naming: {subject}-{descriptor}-opt.png
Checklist: Hero image/video, 1 image per section (5-7 min), 1+ animated GIF, all < 500KB, descriptive alt text.
Phase 4: Audio Narration
Generate TTS audio for each post so readers can listen. Pre-generate at pipeline time, not on-demand. See references/tts-audio-generation.md for full engine comparison, API details, and batch scripts.
Compounding skills: /openrocket-sim (batch scripting patterns), /remotion-best-practices (media pipeline).
TTS Engine Selection
| Engine | When to use |
|---|
| Voicebox (localhost:17493) | Best quality. Voice cloning. GPU available. POST /generate → GET /audio/{id} |
| kokoro-tts | Fast batch default. CLI-first. kokoro-tts input.txt output.wav --voice af_sarah |
| Edge TTS | No local GPU. edge-tts --text "..." --voice en-US-AndrewNeural --write-media out.mp3 |
Quick Generation
slug="my-post"
sed '1{/^---$/!q;};1,/^---$/d' apps/chat/content/writing/$slug.mdx \
| kokoro-tts - /tmp/$slug.wav --voice af_sarah
ffmpeg -i /tmp/$slug.wav -codec:a libmp3lame -b:a 128k apps/chat/public/audio/writing/$slug.mp3
Integration
- Place MP3 at
public/audio/writing/{slug}.mp3
- Add
audio: /audio/writing/{slug}.mp3 to post frontmatter
ContentArticle component renders <audio> player with full controls (play/pause, seek, skip ±10s)- Falls back to Web Speech API if no audio file
Checklist:
Phase 5: Video
Compounding skills: /remotion-best-practices — read rules for animations, sequencing, transitions, images, text. Audio from Phase 4 can be used as voiceover track in Remotion compositions.
Video structure (15-30s):
Title (3-4s) → Stats (3s) → Screenshots (2-3s each) → Workflow (3-4s) → Closing (3-4s)
Key Remotion rules: Use Img + staticFile() (never <img>). Use spring() for organic motion. Use Sequence with premountFor. No CSS transitions or Tailwind animation classes.
Hybrid AI + Remotion Pipeline
Combine AI-generated footage with Remotion motion graphics for production-quality output:
Nano Banana → hero images, backgrounds, social cards
Veo 3.1 → cinematic B-roll clips (8s each, 4K, with audio)
Remotion → motion graphics, titles, transitions, data viz
FFmpeg → preprocess AI clips, final GIF conversion
In Remotion compositions:
<OffthreadVideo src={staticFile("assets/veo-clip.mp4")} style={{ objectFit: "cover" }} />
<Img src={staticFile("assets/nano-banana-hero.png")} />
Use <TransitionSeries> from @remotion/transitions to blend AI clips with motion graphics scenes via fade/wipe/slide transitions.
Render Commands
cd /tmp/{project}-remotion && bun install
npx remotion render {Id} --output out/video.mp4
ffmpeg -y -i out/video.mp4 -vf "fps=12,scale=960:-1:flags=lanczos" -c:v gif out/video.gif
Phase 6: Social Distribution
See references/social-distribution.md for copy patterns and references/social-publishing.md for CLI/MCP tool setup.
X Thread (5-8 tweets)
- Hook — surprising stat, contrarian claim, or earned insight (50% of effort here)
- Context — set the scene
3-6. Key insights — one per tweet, image every 2-3 tweets
- Strongest evidence
- CTA — link, follow, or question
Publishing: Use xurl CLI or Twitter MCP server to post directly.
xurl post "1/7 — [Hook tweet text]"
xurl media upload hero-image.png
xurl post "2/7 — [Context]" --media-id MEDIA_ID
Instagram Carousel (8-12 slides, 1080x1350px)
Use /pencil to design slides. Cover → Problem → Insights (1/slide) → Stat → Summary → CTA.
Publishing: Use Instagram MCP server (ig-mcp) or Meta Graph API.
LinkedIn Post
Hook in first 210 chars. 2-3 paragraphs + bullet list + CTA. 3-5 hashtags.
Publishing: Use LinkedIn MCP server (linkedin-mcp) or REST API with OAuth token.
Phase 7: Deploy
git checkout -b content/{slug}
git add apps/chat/content/writing/{slug}.mdx apps/chat/public/images/writing/{slug}/
git commit -m "content: add {title}"
git push -u origin content/{slug}
gh pr create --title "content: {short title}" --body "..."
