ASSA: the antisocial social agent extension

ASSA lets you get timeline digests and have conversations with people on X (formerly Twitter)via rich UI components. Built for Goose and other MCP-compatible AI agents.

What is ASSA?

ASSA reclaims your social life by moving your activity off of algorithm driven sites and apps and into your personal agent, where you control the flow and decide how to engage. Enjoy:

• Digest tell you what's happening without opening any social app. Let your agent filter spam, ads, and hate speech!
• Have conversations right in your agent's interface, no need to open the X app or site.

Features

• 🔐 Safe authorization via Arcade: Access you social accounts with sharing your password with an agent (or accidentally committing it, oops!)
• 📊 Interactive interface: Mentions displayed with avatars, text. Respond right there!
• 🔁 You're in control: Nothing posts without your explicit approval

Installation

Prerequisites

• Goose (or another MCP-compatible agent)
• Arcade.dev API key

Setup

1. Get your Arcade API key at arcade.dev

2. Clone and install:

   git clone https://github.com/nearestnabors/assa
   cd assa
   bun install
   bun run build

3. Add to Goose App (recommended—Goose CLI can't display interactive UI!)

• In Goose's sidebar, go to Extensiions
• Select "+ Add Custom Extension"
• Add the command: node PATH TO ASSA FOLDER/dist/index.js
• Add Environment variables ARCADE_USER_ID (the email you signed up to Arcade with) and ARCADE_API_KEY (get your Arcade API key here
• Select "Add Extension"

Timeline Digest Setup

The timeline digest feature accesses your "Following" timeline using your existing browser session and Playwright. This is free (no API costs) and uses your logged-in state. (An API would be more robust, but X only makes timeline API functionality available to industrial developers who can afford extortionate fees. So here we are, as hobbyists.)

Prerequisites

1. Google Chrome installed
2. Logged into X in Chrome

Start Chrome with Remote Debugging

Before using timeline digest, start Chrome with the remote debugging port:

Mac:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222

Windows:

"C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222

Linux:

google-chrome --remote-debugging-port=9222

Then make sure you're logged into X in that browser window. (I keep one open and minimized on startup.)

Goose Recipe

ASSA includes a recipe for scheduled timeline digests:

Recipe	Description
x-news-digest.yaml	Daily digest of your Following timeline (requires Chrome with remote debugging)

Import the Recipe

Option 1: Generate a Deep Link

goose recipe deeplink recipes/x-news-digest.yaml

This outputs a goose://recipe?config=... URL. Paste it in a browser to import into Goose Desktop.

Option 2: Import in Goose Desktop

1. Open Goose Desktop
2. Click Recipes in the sidebar
3. Click Import Recipe or browse for file
4. Choose recipes/x-news-digest.yaml from the Recipe File input field

Option 3: Run via CLI

goose run --recipe recipes/x-news-digest.yaml

Schedule the Recipe

After importing, on the Recipes screen:

1. Click the clock icon next to the recipe
2. Select the frequency and time in the Add Schedule modal
3. Click Save

Note: Requires Chrome running with --remote-debugging-port=9222.

Tools

Tool	Description
x_auth_status	Check authentication, show connect button if needed
x_conversations	Show unreplied mentions as a conversation inbox
x_dismiss_conversation	Dismiss a conversation (reappears on new activity)
x_draft_tweet	Create draft with preview
x_post_tweet	Post after approval
x_timeline_digest	Fetch and summarize your Following timeline (past 24h)
x_show_tweet	Display a single tweet as a rich card with reply option

Development

# Run in development mode (auto-reload)
bun dev

# Type check
bun typecheck

# Lint check
bun check

# Run tests
bun test

# Run tests in watch mode
bun test:watch

# Build for production
bun run build

Testing

ASSA uses Bun's built-in test runner with Jest-compatible syntax.

Running Tests

# Run all tests
bun test

# Run tests in watch mode (re-runs on file changes)
bun test:watch

# Run a specific test file
bun test src/__tests__/utils/time.test.ts

# Run tests matching a pattern
bun test --grep "snowflake"

Test Structure

Tests are located in src/__tests__/ mirroring the source structure:

src/
├── __tests__/
│   ├── state/
│   │   └── manager.test.ts    # State management tests
│   ├── tools/
│   │   └── dismiss-conversation.test.ts
│   └── utils/
│       └── time.test.ts       # Time utility tests
├── state/
│   └── manager.ts
├── tools/
│   └── ...
└── utils/
    └── time.ts

Writing Tests

Create a .test.ts file in the appropriate __tests__ subdirectory:

import { describe, expect, test } from "bun:test";
import { myFunction } from "../../utils/my-module.js";

describe("myFunction", () => {
  test("does something expected", () => {
    const result = myFunction("input");
    expect(result).toBe("expected output");
  });
});

Mocking

Use mock.module() to mock Node.js modules:

import { mock } from "bun:test";

// Mock before importing the module that uses it
mock.module("node:os", () => ({
  homedir: () => "/tmp/test-home",
}));

// Now import your module
import { myFunction } from "../../state/manager.js";

Test Isolation

When testing stateful modules, use unique IDs and clean up between tests:

import { beforeEach } from "bun:test";

let testCounter = 0;
function uniqueId(prefix: string): string {
  return `${prefix}_${Date.now()}_${++testCounter}`;
}

beforeEach(() => {
  clearState(); // Reset shared state
});

Getting an Arcade API Key

1. Go to arcade.dev
2. Create an account
3. Navigate to API Keys
4. Create a new key
5. Add it to your .env file

Roadmap

Completed

• Migrate to React components
• Custom CSS design system (9 color palettes, semantic tokens)
• Timeline digest via Playwright browser automation
• Goose recipe for scheduled digests

Next Steps

• Make the "reply UI" smaller:
  • Add small "dismiss" and "reply" icons in the lower left corner of each card
  • Clicking "reply" replaces icons with input area and reply button
  • Clicking outside closes the UI and brings back the icons

Future

• Add X.GetMutedUsers to Arcade to filter muted accounts from conversations
• Add media expansion to Arcade to show images in tweets
• VIP accounts feature (track specific users)
• If a Tweet is a reply, show the original tweet as a stylized quote above the comment
• If a tweet quotes another tweet, show the quoted tweet below the comment

Known Limitations

• No DM support — Arcade's X integration doesn't include DM access
• 7-day limit — X search only goes back 7 days
