handling-attachments
File attachment handling for XMTP agents. Use when sending or receiving images, files, or any encrypted remote attachments. Triggers on file upload, image sending, or remote attachment handling.
What this skill does
# XMTP attachments
Handle file attachments using encrypted remote attachments. Files are encrypted locally, uploaded to your storage provider, and sent as a remote attachment message.
## When to apply
Reference these guidelines when:
- Sending files or images from an agent
- Receiving and downloading attachments
- Implementing custom upload storage
- Working with encrypted file transfers
## Rule categories by priority
| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Send | CRITICAL | `send-` |
| 2 | Receive | CRITICAL | `receive-` |
| 3 | Upload | HIGH | `upload-` |
## Quick reference
### Send (CRITICAL)
- `send-remote-attachment` - Send encrypted file attachments
### Receive (CRITICAL)
- `receive-attachment` - Download and decrypt attachments
### Upload (HIGH)
- `upload-callback` - Implement custom upload storage (Pinata, S3, etc.)
## Quick start
```typescript
import { type AttachmentUploadCallback } from "@xmtp/agent-sdk/util";
// Send an attachment
const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
await ctx.conversation.sendRemoteAttachment(file, uploadCallback);
// Receive an attachment
agent.on("attachment", async (ctx) => {
const attachment = await downloadRemoteAttachment(ctx.message.content, agent);
console.log(`Received: ${attachment.filename}`);
});
```
## How to use
Read individual rule files for detailed explanations:
```
rules/send-remote-attachment.md
rules/receive-attachment.md
rules/upload-callback.md
```
Related in Image & Video
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.
