🤖 Discord.py × OMP Plugin Cheat Sheet

🤖 Discord.py × OMP Plugin Cheat Sheet #

Bridge a discord.py bot (Python) with the OMP coding agent extension system (Bun/TS) — from zero to full bidirectional integration.

🧠 Core Concept #

OMP extensions = TypeScript/Bun. discord.py = Python. They’re separate runtimes. You bridge them via one of three tiers:

	🪝 Tier 1: Webhook	🔧 Tier 2: MCP Server	🌉 Tier 3: Extension + Bot
Direction	OMP → Discord only	Both (LLM invokes tools)	Both (event-driven)
Needs Python?	❌ No	✅ Yes	✅ Yes
Needs Bot Token?	❌ No (webhook URL)	✅ Yes	✅ Yes
Discord → OMP?	❌	❌	✅
Auto-notify events?	✅	❌	✅
LLM calls Discord?	❌	✅	✅
Setup time	~5 min	~15 min	~30–60 min
Deps	None	`discord.py`, `mcp`	`discord.py`, `aiohttp`

⚡ OMP Extension Contract (All Tiers) #

// ~/.omp/agent/extensions/my-ext/index.ts
import type { ExtensionAPI } from "@oh-my-pi/pi-coding-agent";

export default function myExt(pi: ExtensionAPI) {
  // ── Registration Phase (sync) ──
  pi.setLabel("My Extension");

  pi.on("agent_end", async (event, ctx) => { /* ... */ });
  pi.on("session_start", async (event, ctx) => { /* ... */ });

  pi.registerTool({ name: "my_tool", /* ... */ });
  pi.registerCommand("my-cmd", { /* ... */ });

  // ⚠️ CANNOT call pi.sendMessage() during load — only in handlers
}

📡 Key Lifecycle Events #

session_start → input → agent_start → turn_start
  → tool_call → tool_execution_start → tool_execution_end → tool_result
  → turn_end → agent_end → session_shutdown

Event	Use Case	Return
`agent_end`	“Done” notification to Discord	—
`tool_call`	Audit / block dangerous ops	`{ block, reason }`
`tool_result`	Redact secrets before logging	`{ content }`
`session_start`	Init bot connection	—
`session_shutdown`	Cleanup / final flush	—

🪝 Tier 1 — Webhook (Zero-Dep, 5 min) #

No bot. No Python. Just fetch(). OMP → Discord one-way.

A comprehensive guide to the most popular and influential programming libraries and frameworks in 2024. This cheat sheet is categorized by domain to help you find the right tools for your projects, from web development to data science.

🌐 Web Development - Frontend #

These libraries and frameworks are the building blocks of modern, dynamic user interfaces on the web.

1. React #

📝 Description: A JavaScript library developed by Facebook for building user interfaces, especially for single-page applications. It allows developers to create reusable UI components.
✨ Key Features: Virtual DOM for high performance, component-based architecture, vast ecosystem with tools like Redux for state management and React Router for navigation.
🚀 Why Use It?: Versatile, widely adopted, and backed by a massive community. Powers major apps like Facebook and Instagram.

2. Next.js #

📝 Description: A powerful React framework that enables server-side rendering (SSR), static site generation (SSG), and other advanced features out of the box.
✨ Key Features: Optimized for performance and SEO, automatic code splitting, API routes for full-stack development.
🚀 Why Use It?: The go-to framework for building production-ready React applications, used by companies like Netflix and TikTok.

3. Vue.js #

📝 Description: A progressive JavaScript framework known for its simplicity, gentle learning curve, and excellent documentation.
✨ Key Features: Reactive two-way data binding, component-based, can be adopted incrementally for either small features or full-scale applications.
🚀 Why Use It?: Perfect for small to medium-sized projects and for developers who value simplicity and speed.

4. Svelte #

📝 Description: An innovative framework that compiles your code to tiny, framework-less vanilla JavaScript at build time, resulting in highly performant applications.
✨ Key Features: No virtual DOM, minimal bundle sizes, truly reactive with less boilerplate code.
🚀 Why Use It?: For projects where performance and speed are paramount. It offers a refreshing and simple developer experience.

5. Angular #

📝 Description: A full-fledged, TypeScript-based framework by Google for building robust and scalable single-page applications (SPAs).
✨ Key Features: Two-way data binding, dependency injection, comprehensive built-in tools for routing and state management.
🚀 Why Use It?: Ideal for large, enterprise-level applications that require long-term maintainability and a structured architecture.

⚙️ Web Development - Backend #

These frameworks provide the server-side logic, database interactions, and APIs for web applications.

💻 3. Command Central by Project #

🎛️ MixBox (`/home/dev/audio/mixbox/`) #

# Sync package deps via uv
uv sync

# Auto-format and lint code
uv run ruff check . --fix

# Run unit tests (skip slow mix generations)
uv run pytest -m "not rotation"

# Run Quality Gate regression tests (Micro or Afro baseline)
uv run python scripts/rotation_quality_gate.py micro
uv run python scripts/rotation_quality_gate.py afro

# Launch editor UI (Port 55644)
uv run python -m mixbox.gui

📊 AudioFlux Showcase (`/home/dev/audio/audioflux/`) #

# Activate Venv & start all 3 Gradio apps in the background
source .venv/bin/activate
python app/main.py &
python app/unified_main.py &
python mir_playground_standalone.py &

# Kill Gradio apps
pkill -f "main.py\|unified_main.py\|mir_playground_standalone.py"

# Run comprehensive signal engine checks
python -c "exec(open('test_comprehensive.py').read())"

⚡ Hugdown / GIGO (`/home/dev/hugdown/`) #

# Start GOMA (Hugo) and GIMA (React) concurrently
./gigo-start.sh

# Terminate dev environments
./gigo-stop.sh

# Build React client, copy bundles, and generate static Hugo site
./build-all.sh

# Execute integration tests
node test-e2e.js

🤖 Langflow (`/home/dev/py/flow/`) #

# Start visual builder backend (Port 55577)
poetry run langflow run --host 0.0.0.0 --port 55577

⚡ Groq Gradio Services (`/home/dev/py/groqgradio/`) #

# Manage Gradio services via systemd
systemctl --user start groq-minimal.service
systemctl --user start groq-streamlined.service
systemctl --user start groq-main.service
systemctl --user start groq-langflow.service

# Stream service logs
journalctl --user -u groq-minimal -f

🧪 Jamjams Chat Lab (`/home/dev/py/gradiomulti/`) #

# Launch OpenAI OpenRouter Gradio interface (Port 55442)
python app.py

🎞️ MUGEN WebUI (`/home/dev/py/mugen-webui/`) #

# Launch rhythm video generator control UI
python webui.py

🕹️ Active Sandbox #

ai-town: cd /home/dev/active/ai-town && npm run dev
funday: cd /home/dev/active/funday && ./start-funday.sh

🛠️ 4. Essential Coding Conventions #

🐍 Python #

Audio Fallbacks: Use load_audio from audio_core. It targets librosa first and gracefully falls back to pydub-ng.
Audioflux Constraints: Direct imports of librosa or audioflux in /home/dev/audio/audioflux/ are strictly FORBIDDEN. Use local signal math inside app/utils/audio_utils.py.
Pydantic: Declare runtime parameters inside Pydantic structures (packages/dj-engine/src/mixbox/config/models.py).

📦 Node / Vite / Static Site #

CDN Hydration: In Hugdown static views, import React and ReactDOM from https://esm.sh/ inside the HTML layout to avoid dependency bloating.
JWT Credentials: Secure custom endpoints via JWT_SECRET_KEY on HS256 algorithm.

🔬 5. Testing & Verification #

Pytest Suite: Execute unit tests using pytest markers (slow, integration, rotation, perf, viz).
Telemetry Verification: Tracing logs use @langfuse/otel (with a visibility poll timeout of 4000 ms). Never extract get API methods without binding context (traceApi.get(traceId)) to avoid losing this reference context.
