+
+# Claude API
+
+Build applications with the Anthropic Claude API and SDKs.
+
+## When to Activate
+
+- Building applications that call the Claude API
+- Code imports `anthropic` (Python) or `@anthropic-ai/sdk` (TypeScript)
+- User asks about Claude API patterns, tool use, streaming, or vision
+- Implementing agent workflows with Claude Agent SDK
+- Optimizing API costs, token usage, or latency
+
+## Model Selection
+
+| Model | ID | Best For |
+|-------|-----|----------|
+| Opus 4.6 | `claude-opus-4-6` | Complex reasoning, architecture, research |
+| Sonnet 4.6 | `claude-sonnet-4-6` | Balanced coding, most development tasks |
+| Haiku 4.5 | `claude-haiku-4-5-20251001` | Fast responses, high-volume, cost-sensitive |
+
+Default to Sonnet 4.6 unless the task requires deep reasoning (Opus) or speed/cost optimization (Haiku).
+
+## Python SDK
+
+### Installation
+
+```bash
+pip install anthropic
+```
+
+### Basic Message
+
+```python
+import anthropic
+
+client = anthropic.Anthropic()  # reads ANTHROPIC_API_KEY from env
+
+message = client.messages.create(
+    model="claude-sonnet-4-6",
+    max_tokens=1024,
+    messages=[
+        {"role": "user", "content": "Explain async/await in Python"}
+    ]
+)
+print(message.content[0].text)
+```
+
+### Streaming
+
+```python
+with client.messages.stream(
+    model="claude-sonnet-4-6",
+    max_tokens=1024,
+    messages=[{"role": "user", "content": "Write a haiku about coding"}]
+) as stream:
+    for text in stream.text_stream:
+        print(text, end="", flush=True)
+```
+
+### System Prompt
+
+```python
+message = client.messages.create(
+    model="claude-sonnet-4-6",
+    max_tokens=1024,
+    system="You are a senior Python developer. Be concise.",
+    messages=[{"role": "user", "content": "Review this function"}]
+)
+```
+
+## TypeScript SDK
+
+### Installation
+
+```bash
+npm install @anthropic-ai/sdk
+```
+
+### Basic Message
+
+```typescript
+import Anthropic from "@anthropic-ai/sdk";
+
+const client = new Anthropic(); // reads ANTHROPIC_API_KEY from env
+
+const message = await client.messages.create({
+  model: "claude-sonnet-4-6",
+  max_tokens: 1024,
+  messages: [
+    { role: "user", content: "Explain async/await in TypeScript" }
+  ],
+});
+console.log(message.content[0].text);
+```
+
+### Streaming
+
+```typescript
+const stream = client.messages.stream({
+  model: "claude-sonnet-4-6",
+  max_tokens: 1024,
+  messages: [{ role: "user", content: "Write a haiku" }],
+});
+
+for await (const event of stream) {
+  if (event.type === "content_block_delta" && event.delta.type === "text_delta") {
+    process.stdout.write(event.delta.text);
+  }
+}
+```
+
+## Tool Use
+
+Define tools and let Claude call them:
+
+```python
+tools = [
+    {
+        "name": "get_weather",
+        "description": "Get current weather for a location",
+        "input_schema": {
+            "type": "object",
+            "properties": {
+                "location": {"type": "string", "description": "City name"},
+                "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]}
+            },
+            "required": ["location"]
+        }
+    }
+]
+
+message = client.messages.create(
+    model="claude-sonnet-4-6",
+    max_tokens=1024,
+    tools=tools,
+    messages=[{"role": "user", "content": "What's the weather in SF?"}]
+)
+
+# Handle tool use response
+for block in message.content:
+    if block.type == "tool_use":
+        # Execute the tool with block.input
+        result = get_weather(**block.input)
+        # Send result back
+        follow_up = client.messages.create(
+            model="claude-sonnet-4-6",
+            max_tokens=1024,
+            tools=tools,
+            messages=[
+                {"role": "user", "content": "What's the weather in SF?"},
+                {"role": "assistant", "content": message.content},
+                {"role": "user", "content": [
+                    {"type": "tool_result", "tool_use_id": block.id, "content": str(result)}
+                ]}
+            ]
+        )
+```
+
+## Vision
+
+Send images for analysis:
+
+```python
+import base64
+
+with open("diagram.png", "rb") as f:
+    image_data = base64.standard_b64encode(f.read()).decode("utf-8")
+
+message = client.messages.create(
+    model="claude-sonnet-4-6",
+    max_tokens=1024,
+    messages=[{
+        "role": "user",
+        "content": [
+            {"type": "image", "source": {"type": "base64", "media_type": "image/png", "data": image_data}},
+            {"type": "text", "text": "Describe this diagram"}
+        ]
+    }]
+)
+```
+
+## Extended Thinking
+
+For complex reasoning tasks:
+
+```python
+message = client.messages.create(
+    model="claude-sonnet-4-6",
+    max_tokens=16000,
+    thinking={
+        "type": "enabled",
+        "budget_tokens": 10000
+    },
+    messages=[{"role": "user", "content": "Solve this math problem step by step..."}]
+)
+
+for block in message.content:
+    if block.type == "thinking":
+        print(f"Thinking: {block.thinking}")
+    elif block.type == "text":
+        print(f"Answer: {block.text}")
+```
+
+## Prompt Caching
+
+Cache large system prompts or context to reduce costs:
+
+```python
+message = client.messages.create(
+    model="claude-sonnet-4-6",
+    max_tokens=1024,
+    system=[
+        {"type": "text", "text": large_system_prompt, "cache_control": {"type": "ephemeral"}}
+    ],
+    messages=[{"role": "user", "content": "Question about the cached context"}]
+)
+# Check cache usage
+print(f"Cache read: {message.usage.cache_read_input_tokens}")
+print(f"Cache creation: {message.usage.cache_creation_input_tokens}")
+```
+
+## Batches API
+
+Process large volumes asynchronously at 50% cost reduction:
+
+```python
+batch = client.messages.batches.create(
+    requests=[
+        {
+            "custom_id": f"request-{i}",
+            "params": {
+                "model": "claude-sonnet-4-6",
+                "max_tokens": 1024,
+                "messages": [{"role": "user", "content": prompt}]
+            }
+        }
+        for i, prompt in enumerate(prompts)
+    ]
+)
+
+# Poll for completion
+while True:
+    status = client.messages.batches.retrieve(batch.id)
+    if status.processing_status == "ended":
+        break
+    time.sleep(30)
+
+# Get results
+for result in client.messages.batches.results(batch.id):
+    print(result.result.message.content[0].text)
+```
+
+## Claude Agent SDK
+
+Build multi-step agents:
+
+```python
+# Note: Agent SDK API surface may change — check official docs
+import anthropic
+
+# Define tools as functions
+tools = [{
+    "name": "search_codebase",
+    "description": "Search the codebase for relevant code",
+    "input_schema": {
+        "type": "object",
+        "properties": {"query": {"type": "string"}},
+        "required": ["query"]
+    }
+}]
+
+# Run an agentic loop with tool use
+client = anthropic.Anthropic()
+messages = [{"role": "user", "content": "Review the auth module for security issues"}]
+
+while True:
+    response = client.messages.create(
+        model="claude-sonnet-4-6",
+        max_tokens=4096,
+        tools=tools,
+        messages=messages,
+    )
+    if response.stop_reason == "end_turn":
+        break
+    # Handle tool calls and continue the loop
+    messages.append({"role": "assistant", "content": response.content})
+    # ... execute tools and append tool_result messages
+```
+
+## Cost Optimization
+
+| Strategy | Savings | When to Use |
+|----------|---------|-------------|
+| Prompt caching | Up to 90% on cached tokens | Repeated system prompts or context |
+| Batches API | 50% | Non-time-sensitive bulk processing |
+| Haiku instead of Sonnet | ~75% | Simple tasks, classification, extraction |
+| Shorter max_tokens | Variable | When you know output will be short |
+| Streaming | None (same cost) | Better UX, same price |
+
+## Error Handling
+
+```python
+from anthropic import APIError, RateLimitError, APIConnectionError
+
+try:
+    message = client.messages.create(...)
+except RateLimitError:
+    # Back off and retry
+    time.sleep(60)
+except APIConnectionError:
+    # Network issue, retry with backoff
+    pass
+except APIError as e:
+    print(f"API error {e.status_code}: {e.message}")
+```
+
+## Environment Setup
+
+```bash
+# Required
+export ANTHROPIC_API_KEY="your-api-key-here"
+
+# Optional: set default model
+export ANTHROPIC_MODEL="claude-sonnet-4-6"
+```
+
+Never hardcode API keys. Always use environment variables.

+name: crosspost
+description: Multi-platform content distribution across X, LinkedIn, Threads, and Bluesky. Adapts content per platform using content-engine patterns. Never posts identical content cross-platform. Use when the user wants to distribute content across social platforms.
+origin: ECC
+---
+
+# Crosspost
+
+Distribute content across multiple social platforms with platform-native adaptation.
+
+## When to Activate
+
+- User wants to post content to multiple platforms
+- Publishing announcements, launches, or updates across social media
+- Repurposing a post from one platform to others
+- User says "crosspost", "post everywhere", "share on all platforms", or "distribute this"
+
+## Core Rules
+
+1. **Never post identical content cross-platform.** Each platform gets a native adaptation.
+2. **Primary platform first.** Post to the main platform, then adapt for others.
+3. **Respect platform conventions.** Length limits, formatting, link handling all differ.
+4. **One idea per post.** If the source content has multiple ideas, split across posts.
+5. **Attribution matters.** If crossposting someone else's content, credit the source.
+
+## Platform Specifications
+
+| Platform | Max Length | Link Handling | Hashtags | Media |
+|----------|-----------|---------------|----------|-------|
+| X | 280 chars (4000 for Premium) | Counted in length | Minimal (1-2 max) | Images, video, GIFs |
+| LinkedIn | 3000 chars | Not counted in length | 3-5 relevant | Images, video, docs, carousels |
+| Threads | 500 chars | Separate link attachment | None typical | Images, video |
+| Bluesky | 300 chars | Via facets (rich text) | None (use feeds) | Images |
+
+## Workflow
+
+### Step 1: Create Source Content
+
+Start with the core idea. Use `content-engine` skill for high-quality drafts:
+- Identify the single core message
+- Determine the primary platform (where the audience is biggest)
+- Draft the primary platform version first
+
+### Step 2: Identify Target Platforms
+
+Ask the user or determine from context:
+- Which platforms to target
+- Priority order (primary gets the best version)
+- Any platform-specific requirements (e.g., LinkedIn needs professional tone)
+
+### Step 3: Adapt Per Platform
+
+For each target platform, transform the content:
+
+**X adaptation:**
+- Open with a hook, not a summary
+- Cut to the core insight fast
+- Keep links out of main body when possible
+- Use thread format for longer content
+
+**LinkedIn adaptation:**
+- Strong first line (visible before "see more")
+- Short paragraphs with line breaks
+- Frame around lessons, results, or professional takeaways
+- More explicit context than X (LinkedIn audience needs framing)
+
+**Threads adaptation:**
+- Conversational, casual tone
+- Shorter than LinkedIn, less compressed than X
+- Visual-first if possible
+
+**Bluesky adaptation:**
+- Direct and concise (300 char limit)
+- Community-oriented tone
+- Use feeds/lists for topic targeting instead of hashtags
+
+### Step 4: Post Primary Platform
+
+Post to the primary platform first:
+- Use `x-api` skill for X
+- Use platform-specific APIs or tools for others
+- Capture the post URL for cross-referencing
+
+### Step 5: Post to Secondary Platforms
+
+Post adapted versions to remaining platforms:
+- Stagger timing (not all at once — 30-60 min gaps)
+- Include cross-platform references where appropriate ("longer thread on X" etc.)
+
+## Content Adaptation Examples
+
+### Source: Product Launch
+
+**X version:**
+```
+We just shipped [feature].
+
+[One specific thing it does that's impressive]
+
+[Link]
+```
+
+**LinkedIn version:**
+```
+Excited to share: we just launched [feature] at [Company].
+
+Here's why it matters:
+
+[2-3 short paragraphs with context]
+
+[Takeaway for the audience]
+
+[Link]
+```
+
+**Threads version:**
+```
+just shipped something cool — [feature]
+
+[casual explanation of what it does]
+
+link in bio
+```
+
+### Source: Technical Insight
+
+**X version:**
+```
+TIL: [specific technical insight]
+
+[Why it matters in one sentence]
+```
+
+**LinkedIn version:**
+```
+A pattern I've been using that's made a real difference:
+
+[Technical insight with professional framing]
+
+[How it applies to teams/orgs]
+
+#relevantHashtag
+```
+
+## API Integration
+
+### Batch Crossposting Service (Example Pattern)
+If using a crossposting service (e.g., Postbridge, Buffer, or a custom API), the pattern looks like:
+
+```python
+import requests
+
+resp = requests.post(
+    "https://api.postbridge.io/v1/posts",
+    headers={"Authorization": f"Bearer {os.environ['POSTBRIDGE_API_KEY']}"},
+    json={
+        "platforms": ["twitter", "linkedin", "threads"],
+        "content": {
+            "twitter": {"text": x_version},
+            "linkedin": {"text": linkedin_version},
+            "threads": {"text": threads_version}
+        }
+    }
+)
+```
+
+### Manual Posting
+Without Postbridge, post to each platform using its native API:
+- X: Use `x-api` skill patterns
+- LinkedIn: LinkedIn API v2 with OAuth 2.0
+- Threads: Threads API (Meta)
+- Bluesky: AT Protocol API
+
+## Quality Gate
+
+Before posting:
+- [ ] Each platform version reads naturally for that platform
+- [ ] No identical content across platforms
+- [ ] Length limits respected
+- [ ] Links work and are placed appropriately
+- [ ] Tone matches platform conventions
+- [ ] Media is sized correctly for each platform

+origin: ECC
+---
+
+# Deep Research
+
+Produce thorough, cited research reports from multiple web sources using firecrawl and exa MCP tools.
+
+## When to Activate
+
+- User asks to research any topic in depth
+- Competitive analysis, technology evaluation, or market sizing
+- Due diligence on companies, investors, or technologies
+- Any question requiring synthesis from multiple sources
+- User says "research", "deep dive", "investigate", or "what's the current state of"
+
+## MCP Requirements
+
+At least one of:
+- **firecrawl** — `firecrawl_search`, `firecrawl_scrape`, `firecrawl_crawl`
+- **exa** — `web_search_exa`, `web_search_advanced_exa`, `crawling_exa`
+
+Both together give the best coverage. Configure in `~/.claude.json` or `~/.codex/config.toml`.
+
+## Workflow
+
+### Step 1: Understand the Goal
+
+Ask 1-2 quick clarifying questions:
+- "What's your goal — learning, making a decision, or writing something?"
+- "Any specific angle or depth you want?"
+
+If the user says "just research it" — skip ahead with reasonable defaults.
+
+### Step 2: Plan the Research
+
+Break the topic into 3-5 research sub-questions. Example:
+- Topic: "Impact of AI on healthcare"
+  - What are the main AI applications in healthcare today?
+  - What clinical outcomes have been measured?
+  - What are the regulatory challenges?
+  - What companies are leading this space?
+  - What's the market size and growth trajectory?
+
+### Step 3: Execute Multi-Source Search
+
+For EACH sub-question, search using available MCP tools:
+
+**With firecrawl:**
+```
+firecrawl_search(query: "<sub-question keywords>", limit: 8)
+```
+
+**With exa:**
+```
+web_search_exa(query: "<sub-question keywords>", numResults: 8)
+web_search_advanced_exa(query: "<keywords>", numResults: 5, startPublishedDate: "2025-01-01")
+```
+
+**Search strategy:**
+- Use 2-3 different keyword variations per sub-question
+- Mix general and news-focused queries
+- Aim for 15-30 unique sources total
+- Prioritize: academic, official, reputable news > blogs > forums
+
+### Step 4: Deep-Read Key Sources
+
+For the most promising URLs, fetch full content:
+
+**With firecrawl:**
+```
+firecrawl_scrape(url: "<url>")
+```
+
+**With exa:**
+```
+crawling_exa(url: "<url>", tokensNum: 5000)
+```
+
+Read 3-5 key sources in full for depth. Do not rely only on search snippets.
+
+### Step 5: Synthesize and Write Report
+
+Structure the report:
+
+```markdown
+# [Topic]: Research Report
+*Generated: [date] | Sources: [N] | Confidence: [High/Medium/Low]*
+
+## Executive Summary
+[3-5 sentence overview of key findings]
+
+## 1. [First Major Theme]
+[Findings with inline citations]
+- Key point ([Source Name](url))
+- Supporting data ([Source Name](url))
+
+## 2. [Second Major Theme]
+...
+
+## 3. [Third Major Theme]
+...
+
+## Key Takeaways
+- [Actionable insight 1]
+- [Actionable insight 2]
+- [Actionable insight 3]
+
+## Sources
+1. [Title](url) — [one-line summary]
+2. ...
+
+## Methodology
+Searched [N] queries across web and news. Analyzed [M] sources.
+Sub-questions investigated: [list]
+```
+
+### Step 6: Deliver
+
+- **Short topics**: Post the full report in chat
+- **Long reports**: Post the executive summary + key takeaways, save full report to a file
+
+## Parallel Research with Subagents
+
+For broad topics, use Claude Code's Task tool to parallelize:
+
+```
+Launch 3 research agents in parallel:
+1. Agent 1: Research sub-questions 1-2
+2. Agent 2: Research sub-questions 3-4
+3. Agent 3: Research sub-question 5 + cross-cutting themes
+```
+
+Each agent searches, reads sources, and returns findings. The main session synthesizes into the final report.
+
+## Quality Rules
+
+1. **Every claim needs a source.** No unsourced assertions.
+2. **Cross-reference.** If only one source says it, flag it as unverified.
+3. **Recency matters.** Prefer sources from the last 12 months.
+4. **Acknowledge gaps.** If you couldn't find good info on a sub-question, say so.
+5. **No hallucination.** If you don't know, say "insufficient data found."
+6. **Separate fact from inference.** Label estimates, projections, and opinions clearly.
+
+## Examples
+
+```
+"Research the current state of nuclear fusion energy"
+"Deep dive into Rust vs Go for backend services in 2026"
+"Research the best strategies for bootstrapping a SaaS business"
+"What's happening with the US housing market right now?"
+"Investigate the competitive landscape for AI code editors"
+```

+
+# dmux Workflows
+
+Orchestrate parallel AI agent sessions using dmux, a tmux pane manager for agent harnesses.
+
+## When to Activate
+
+- Running multiple agent sessions in parallel
+- Coordinating work across Claude Code, Codex, and other harnesses
+- Complex tasks that benefit from divide-and-conquer parallelism
+- User says "run in parallel", "split this work", "use dmux", or "multi-agent"
+
+## What is dmux
+
+dmux is a tmux-based orchestration tool that manages AI agent panes:
+- Press `n` to create a new pane with a prompt
+- Press `m` to merge pane output back to the main session
+- Supports: Claude Code, Codex, OpenCode, Cline, Gemini, Qwen
+
+**Install:** `npm install -g dmux` or see [github.com/standardagents/dmux](https://github.com/standardagents/dmux)
+
+## Quick Start
+
+```bash
+# Start dmux session
+dmux
+
+# Create agent panes (press 'n' in dmux, then type prompt)
+# Pane 1: "Implement the auth middleware in src/auth/"
+# Pane 2: "Write tests for the user service"
+# Pane 3: "Update API documentation"
+
+# Each pane runs its own agent session
+# Press 'm' to merge results back
+```
+
+## Workflow Patterns
+
+### Pattern 1: Research + Implement
+
+Split research and implementation into parallel tracks:
+
+```
+Pane 1 (Research): "Research best practices for rate limiting in Node.js.
+  Check current libraries, compare approaches, and write findings to
+  /tmp/rate-limit-research.md"
+
+Pane 2 (Implement): "Implement rate limiting middleware for our Express API.
+  Start with a basic token bucket, we'll refine after research completes."
+
+# After Pane 1 completes, merge findings into Pane 2's context
+```
+
+### Pattern 2: Multi-File Feature
+
+Parallelize work across independent files:
+
+```
+Pane 1: "Create the database schema and migrations for the billing feature"
+Pane 2: "Build the billing API endpoints in src/api/billing/"
+Pane 3: "Create the billing dashboard UI components"
+
+# Merge all, then do integration in main pane
+```
+
+### Pattern 3: Test + Fix Loop
+
+Run tests in one pane, fix in another:
+
+```
+Pane 1 (Watcher): "Run the test suite in watch mode. When tests fail,
+  summarize the failures."
+
+Pane 2 (Fixer): "Fix failing tests based on the error output from pane 1"
+```
+
+### Pattern 4: Cross-Harness
+
+Use different AI tools for different tasks:
+
+```
+Pane 1 (Claude Code): "Review the security of the auth module"
+Pane 2 (Codex): "Refactor the utility functions for performance"
+Pane 3 (Claude Code): "Write E2E tests for the checkout flow"
+```
+
+### Pattern 5: Code Review Pipeline
+
+Parallel review perspectives:
+
+```
+Pane 1: "Review src/api/ for security vulnerabilities"
+Pane 2: "Review src/api/ for performance issues"
+Pane 3: "Review src/api/ for test coverage gaps"
+
+# Merge all reviews into a single report
+```
+
+## Best Practices
+
+1. **Independent tasks only.** Don't parallelize tasks that depend on each other's output.
+2. **Clear boundaries.** Each pane should work on distinct files or concerns.
+3. **Merge strategically.** Review pane output before merging to avoid conflicts.
+4. **Use git worktrees.** For file-conflict-prone work, use separate worktrees per pane.
+5. **Resource awareness.** Each pane uses API tokens — keep total panes under 5-6.
+
+## Git Worktree Integration
+
+For tasks that touch overlapping files:
+
+```bash
+# Create worktrees for isolation
+git worktree add ../feature-auth feat/auth
+git worktree add ../feature-billing feat/billing
+
+# Run agents in separate worktrees
+# Pane 1: cd ../feature-auth && claude
+# Pane 2: cd ../feature-billing && claude
+
+# Merge branches when done
+git merge feat/auth
+git merge feat/billing
+```
+
+## Complementary Tools
+
+| Tool | What It Does | When to Use |
+|------|-------------|-------------|
+| **dmux** | tmux pane management for agents | Parallel agent sessions |
+| **Superset** | Terminal IDE for 10+ parallel agents | Large-scale orchestration |
+| **Claude Code Task tool** | In-process subagent spawning | Programmatic parallelism within a session |
+| **Codex multi-agent** | Built-in agent roles | Codex-specific parallel work |
+
+## Troubleshooting
+
+- **Pane not responding:** Check if the agent session is waiting for input. Use `m` to read output.
+- **Merge conflicts:** Use git worktrees to isolate file changes per pane.
+- **High token usage:** Reduce number of parallel panes. Each pane is a full agent session.
+- **tmux not found:** Install with `brew install tmux` (macOS) or `apt install tmux` (Linux).

+import requests
+
+resp = requests.post(
+    "https://api.elevenlabs.io/v1/text-to-speech/<voice_id>",
+    headers={
+        "xi-api-key": os.environ["ELEVENLABS_API_KEY"],
+        "Content-Type": "application/json"
+    },
+    json={

+
+```
+estimate_cost(model_name: "fal-ai/nano-banana-pro", input: {...})
+```
+
+## Model Discovery
+
+Find models for specific tasks:
+
+```
+search(query: "text to video")
+find(model_name: "fal-ai/seedance-1-0-pro")
+models()
+```
+
+## Tips
+
+- Use `seed` for reproducible results when iterating on prompts
+- Start with lower-cost models (Nano Banana 2) for prompt iteration, then switch to Pro for finals
+- For video, keep prompts descriptive but concise — focus on motion and scene
+- Image-to-video produces more controlled results than pure text-to-video
+- Check `estimate_cost` before running expensive video generations

+
+# Video Editing
+
+AI-assisted editing for real footage. Not generation from prompts. Editing existing video fast.
+
+## When to Activate
+
+- User wants to edit, cut, or structure video footage
+- Turning long recordings into short-form content
+- Building vlogs, tutorials, or demo videos from raw capture
+- Adding overlays, subtitles, music, or voiceover to existing video
+- Reframing video for different platforms (YouTube, TikTok, Instagram)
+- User says "edit video", "cut this footage", "make a vlog", or "video workflow"
+
+## Core Thesis
+
+AI video editing is useful when you stop asking it to create the whole video and start using it to compress, structure, and augment real footage. The value is not generation. The value is compression.
+
+## The Pipeline
+
+```
+Screen Studio / raw footage
+  → Claude / Codex
+  → FFmpeg
+  → Remotion
+  → ElevenLabs / fal.ai
+  → Descript or CapCut
+```
+
+Each layer has a specific job. Do not skip layers. Do not try to make one tool do everything.
+
+## Layer 1: Capture (Screen Studio / Raw Footage)
+
+Collect the source material:
+- **Screen Studio**: polished screen recordings for app demos, coding sessions, browser workflows
+- **Raw camera footage**: vlog footage, interviews, event recordings
+- **Desktop capture via VideoDB**: session recording with real-time context (see `videodb` skill)
+
+Output: raw files ready for organization.
+
+## Layer 2: Organization (Claude / Codex)
+
+Use Claude Code or Codex to:
+- **Transcribe and label**: generate transcript, identify topics and themes
+- **Plan structure**: decide what stays, what gets cut, what order works
+- **Identify dead sections**: find pauses, tangents, repeated takes
+- **Generate edit decision list**: timestamps for cuts, segments to keep
+- **Scaffold FFmpeg and Remotion code**: generate the commands and compositions
+
+```
+Example prompt:
+"Here's the transcript of a 4-hour recording. Identify the 8 strongest segments
+for a 24-minute vlog. Give me FFmpeg cut commands for each segment."
+```
+
+This layer is about structure, not final creative taste.
+
+## Layer 3: Deterministic Cuts (FFmpeg)
+
+FFmpeg handles the boring but critical work: splitting, trimming, concatenating, and preprocessing.
+
+### Extract segment by timestamp
+
+```bash
+ffmpeg -i raw.mp4 -ss 00:12:30 -to 00:15:45 -c copy segment_01.mp4
+```
+
+### Batch cut from edit decision list
+
+```bash
+#!/bin/bash
+# cuts.txt: start,end,label
+while IFS=, read -r start end label; do
+  ffmpeg -i raw.mp4 -ss "$start" -to "$end" -c copy "segments/${label}.mp4"
+done < cuts.txt
+```
+
+### Concatenate segments
+
+```bash
+# Create file list
+for f in segments/*.mp4; do echo "file '$f'"; done > concat.txt
+ffmpeg -f concat -safe 0 -i concat.txt -c copy assembled.mp4
+```
+
+### Create proxy for faster editing
+
+```bash
+ffmpeg -i raw.mp4 -vf "scale=960:-2" -c:v libx264 -preset ultrafast -crf 28 proxy.mp4
+```
+
+### Extract audio for transcription
+
+```bash
+ffmpeg -i raw.mp4 -vn -acodec pcm_s16le -ar 16000 audio.wav
+```
+
+### Normalize audio levels
+
+```bash
+ffmpeg -i segment.mp4 -af loudnorm=I=-16:TP=-1.5:LRA=11 -c:v copy normalized.mp4
+```
+
+## Layer 4: Programmable Composition (Remotion)
+
+Remotion turns editing problems into composable code. Use it for things that traditional editors make painful:
+
+### When to use Remotion
+
+- Overlays: text, images, branding, lower thirds
+- Data visualizations: charts, stats, animated numbers
+- Motion graphics: transitions, explainer animations
+- Composable scenes: reusable templates across videos
+- Product demos: annotated screenshots, UI highlights
+
+### Basic Remotion composition
+
+```tsx
+import { AbsoluteFill, Sequence, Video, useCurrentFrame } from "remotion";
+
+export const VlogComposition: React.FC = () => {
+  const frame = useCurrentFrame();
+
+  return (
+    <AbsoluteFill>
+      {/* Main footage */}
+      <Sequence from={0} durationInFrames={300}>
+        <Video src="/segments/intro.mp4" />
+      </Sequence>
+
+      {/* Title overlay */}
+      <Sequence from={30} durationInFrames={90}>
+        <AbsoluteFill style={{
+          justifyContent: "center",
+          alignItems: "center",
+        }}>
+          <h1 style={{
+            fontSize: 72,
+            color: "white",
+            textShadow: "2px 2px 8px rgba(0,0,0,0.8)",
+          }}>
+            The AI Editing Stack
+          </h1>
+        </AbsoluteFill>
+      </Sequence>
+
+      {/* Next segment */}
+      <Sequence from={300} durationInFrames={450}>
+        <Video src="/segments/demo.mp4" />
+      </Sequence>
+    </AbsoluteFill>
+  );
+};
+```
+
+### Render output
+
+```bash
+npx remotion render src/index.ts VlogComposition output.mp4
+```
+
+See the [Remotion docs](https://www.remotion.dev/docs) for detailed patterns and API reference.
+
+## Layer 5: Generated Assets (ElevenLabs / fal.ai)
+
+Generate only what you need. Do not generate the whole video.
+
+### Voiceover with ElevenLabs
+
+```python
+import os
+import requests
+
+resp = requests.post(
+    f"https://api.elevenlabs.io/v1/text-to-speech/{voice_id}",
+    headers={
+        "xi-api-key": os.environ["ELEVENLABS_API_KEY"],
+        "Content-Type": "application/json"
+    },
+    json={
+        "text": "Your narration text here",
+        "model_id": "eleven_turbo_v2_5",
+        "voice_settings": {"stability": 0.5, "similarity_boost": 0.75}
+    }
+)
+with open("voiceover.mp3", "wb") as f:
+    f.write(resp.content)
+```
+
+### Music and SFX with fal.ai
+
+Use the `fal-ai-media` skill for:
+- Background music generation
+- Sound effects (ThinkSound model for video-to-audio)
+- Transition sounds
+
+### Generated visuals with fal.ai
+
+Use for insert shots, thumbnails, or b-roll that doesn't exist:
+```
+generate(model_name: "fal-ai/nano-banana-pro", input: {
+  "prompt": "professional thumbnail for tech vlog, dark background, code on screen",
+  "image_size": "landscape_16_9"
+})
+```
+
+### VideoDB generative audio
+
+If VideoDB is configured:
+```python
+voiceover = coll.generate_voice(text="Narration here", voice="alloy")
+music = coll.generate_music(prompt="lo-fi background for coding vlog", duration=120)
+sfx = coll.generate_sound_effect(prompt="subtle whoosh transition")
+```
+
+## Layer 6: Final Polish (Descript / CapCut)
+
+The last layer is human. Use a traditional editor for:
+- **Pacing**: adjust cuts that feel too fast or slow
+- **Captions**: auto-generated, then manually cleaned
+- **Color grading**: basic correction and mood
+- **Final audio mix**: balance voice, music, and SFX levels
+- **Export**: platform-specific formats and quality settings
+
+This is where taste lives. AI clears the repetitive work. You make the final calls.
+
+## Social Media Reframing
+
+Different platforms need different aspect ratios:
+
+| Platform | Aspect Ratio | Resolution |
+|----------|-------------|------------|
+| YouTube | 16:9 | 1920x1080 |
+| TikTok / Reels | 9:16 | 1080x1920 |
+| Instagram Feed | 1:1 | 1080x1080 |
+| X / Twitter | 16:9 or 1:1 | 1280x720 or 720x720 |
+
+### Reframe with FFmpeg
+
+```bash
+# 16:9 to 9:16 (center crop)
+ffmpeg -i input.mp4 -vf "crop=ih*9/16:ih,scale=1080:1920" vertical.mp4
+
+# 16:9 to 1:1 (center crop)
+ffmpeg -i input.mp4 -vf "crop=ih:ih,scale=1080:1080" square.mp4
+```
+
+### Reframe with VideoDB
+
+```python
+# Smart reframe (AI-guided subject tracking)
+reframed = video.reframe(start=0, end=60, target="vertical", mode=ReframeMode.smart)
+```
+
+## Scene Detection and Auto-Cut
+
+### FFmpeg scene detection
+
+```bash
+# Detect scene changes (threshold 0.3 = moderate sensitivity)
+ffmpeg -i input.mp4 -vf "select='gt(scene,0.3)',showinfo" -vsync vfr -f null - 2>&1 | grep showinfo
+```
+
+### Silence detection for auto-cut
+
+```bash
+# Find silent segments (useful for cutting dead air)
+ffmpeg -i input.mp4 -af silencedetect=noise=-30dB:d=2 -f null - 2>&1 | grep silence
+```
+
+### Highlight extraction
+
+Use Claude to analyze transcript + scene timestamps:
+```
+"Given this transcript with timestamps and these scene change points,
+identify the 5 most engaging 30-second clips for social media."
+```
+
+## What Each Tool Does Best
+
+| Tool | Strength | Weakness |
+|------|----------|----------|
+| Claude / Codex | Organization, planning, code generation | Not the creative taste layer |
+| FFmpeg | Deterministic cuts, batch processing, format conversion | No visual editing UI |
+| Remotion | Programmable overlays, composable scenes, reusable templates | Learning curve for non-devs |
+| Screen Studio | Polished screen recordings immediately | Only screen capture |
+| ElevenLabs | Voice, narration, music, SFX | Not the center of the workflow |
+| Descript / CapCut | Final pacing, captions, polish | Manual, not automatable |
+
+## Key Principles
+
+1. **Edit, don't generate.** This workflow is for cutting real footage, not creating from prompts.
+2. **Structure before style.** Get the story right in Layer 2 before touching anything visual.
+3. **FFmpeg is the backbone.** Boring but critical. Where long footage becomes manageable.
+4. **Remotion for repeatability.** If you'll do it more than once, make it a Remotion component.
+5. **Generate selectively.** Only use AI generation for assets that don't exist, not for everything.
+6. **Taste is the last layer.** AI clears repetitive work. You make the final creative calls.

+description: X/Twitter API integration for posting tweets, threads, reading timelines, search, and analytics. Covers OAuth auth patterns, rate limits, and platform-native content posting. Use when the user wants to interact with X programmatically.
+origin: ECC
+---
+
+# X API
+
+Programmatic interaction with X (Twitter) for posting, reading, searching, and analytics.
+
+## When to Activate
+
+- User wants to post tweets or threads programmatically
+- Reading timeline, mentions, or user data from X
+- Searching X for content, trends, or conversations
+- Building X integrations or bots
+- Analytics and engagement tracking
+- User says "post to X", "tweet", "X API", or "Twitter API"
+
+## Authentication
+
+### OAuth 2.0 (App-Only / User Context)
+
+Best for: read-heavy operations, search, public data.
+
+```bash
+# Environment setup
+export X_BEARER_TOKEN="your-bearer-token"
+```
+
+```python
+import os
+import requests
+
+bearer = os.environ["X_BEARER_TOKEN"]
+headers = {"Authorization": f"Bearer {bearer}"}
+
+# Search recent tweets
+resp = requests.get(
+    "https://api.x.com/2/tweets/search/recent",
+    headers=headers,
+    params={"query": "claude code", "max_results": 10}
+)
+tweets = resp.json()
+```
+
+### OAuth 1.0a (User Context)
+
+Required for: posting tweets, managing account, DMs.
+
+```bash
+# Environment setup — source before use
+export X_API_KEY="your-api-key"
+export X_API_SECRET="your-api-secret"
+export X_ACCESS_TOKEN="your-access-token"
+export X_ACCESS_SECRET="your-access-secret"
+```
+
+```python
+import os
+from requests_oauthlib import OAuth1Session
+
+oauth = OAuth1Session(
+    os.environ["X_API_KEY"],
+    client_secret=os.environ["X_API_SECRET"],
+    resource_owner_key=os.environ["X_ACCESS_TOKEN"],
+    resource_owner_secret=os.environ["X_ACCESS_SECRET"],
+)
+```
+
+## Core Operations
+
+### Post a Tweet
+
+```python
+resp = oauth.post(
+    "https://api.x.com/2/tweets",
+    json={"text": "Hello from Claude Code"}
+)
+resp.raise_for_status()
+tweet_id = resp.json()["data"]["id"]
+```
+
+### Post a Thread
+
+```python
+def post_thread(oauth, tweets: list[str]) -> list[str]:
+    ids = []
+    reply_to = None
+    for text in tweets:
+        payload = {"text": text}
+        if reply_to:
+            payload["reply"] = {"in_reply_to_tweet_id": reply_to}
+        resp = oauth.post("https://api.x.com/2/tweets", json=payload)
+        tweet_id = resp.json()["data"]["id"]
+        ids.append(tweet_id)
+        reply_to = tweet_id
+    return ids
+```
+
+### Read User Timeline
+
+```python
+resp = requests.get(
+    f"https://api.x.com/2/users/{user_id}/tweets",
+    headers=headers,
+    params={
+        "max_results": 10,
+        "tweet.fields": "created_at,public_metrics",
+    }
+)
+```
+
+### Search Tweets
+
+```python
+resp = requests.get(
+    "https://api.x.com/2/tweets/search/recent",
+    headers=headers,
+    params={
+        "query": "from:affaanmustafa -is:retweet",
+        "max_results": 10,
+        "tweet.fields": "public_metrics,created_at",
+    }
+)
+```
+
+### Get User by Username
+
+```python
+resp = requests.get(
+    "https://api.x.com/2/users/by/username/affaanmustafa",
+    headers=headers,
+    params={"user.fields": "public_metrics,description,created_at"}
+)
+```
+
+### Upload Media and Post
+
+```python
+# Media upload uses v1.1 endpoint
+
+# Step 1: Upload media
+media_resp = oauth.post(
+    "https://upload.twitter.com/1.1/media/upload.json",
+    files={"media": open("image.png", "rb")}
+)
+media_id = media_resp.json()["media_id_string"]
+
+# Step 2: Post with media
+resp = oauth.post(
+    "https://api.x.com/2/tweets",
+    json={"text": "Check this out", "media": {"media_ids": [media_id]}}
+)
+```
+
+## Rate Limits Reference
+
+| Endpoint | Limit | Window |
+|----------|-------|--------|
+| POST /2/tweets | 200 | 15 min |
+| GET /2/tweets/search/recent | 450 | 15 min |
+| GET /2/users/:id/tweets | 1500 | 15 min |
+| GET /2/users/by/username | 300 | 15 min |
+| POST media/upload | 415 | 15 min |
+
+Always check `x-rate-limit-remaining` and `x-rate-limit-reset` headers.
+
+```python
+remaining = int(resp.headers.get("x-rate-limit-remaining", 0))
+if remaining < 5:
+    reset = int(resp.headers.get("x-rate-limit-reset", 0))
+    wait = max(0, reset - int(time.time()))
+    print(f"Rate limit approaching. Resets in {wait}s")
+```
+
+## Error Handling
+
+```python
+resp = oauth.post("https://api.x.com/2/tweets", json={"text": content})
+if resp.status_code == 201:
+    return resp.json()["data"]["id"]
+elif resp.status_code == 429:
+    reset = int(resp.headers["x-rate-limit-reset"])
+    raise Exception(f"Rate limited. Resets at {reset}")
+elif resp.status_code == 403:
+    raise Exception(f"Forbidden: {resp.json().get('detail', 'check permissions')}")
+else:
+    raise Exception(f"X API error {resp.status_code}: {resp.text}")
+```
+
+## Security
+
+- **Never hardcode tokens.** Use environment variables or `.env` files.
+- **Never commit `.env` files.** Add to `.gitignore`.
+- **Rotate tokens** if exposed. Regenerate at developer.x.com.
+- **Use read-only tokens** when write access is not needed.
+- **Store OAuth secrets securely** — not in source code or logs.
+
+## Integration with Content Engine
+
+Use `content-engine` skill to generate platform-native content, then post via X API:
+1. Generate content with content-engine (X platform format)
+2. Validate length (280 chars for single tweet)
+3. Post via X API using patterns above
+4. Track engagement via public_metrics
+
