What is mom?

A Slack bot powered by an LLM that can execute bash commands, read/write files, and interact with your development environment. Mom is self-managing. She installs her own tools, programs CLI tools (aka “skills”) she can use to help with your workflows and tasks, configures credentials, and maintains her workspace autonomously.

Features

• Minimal by Design: Turn mom into whatever you need. She builds her own tools without pre-built assumptions

• Self-Managing: Installs tools (apk, npm, etc.), writes scripts, configures credentials. Zero setup from you

• Slack Integration: Responds to @mentions in channels and DMs

• Full Bash Access: Execute any command, read/write files, automate workflows

• Docker Sandbox: Isolate mom in a container (recommended for all use)

• Persistent Workspace: All conversation history, files, and tools stored in one directory you control

• Working Memory & Custom Tools: Mom remembers context across sessions and creates workflow-specific CLI tools (aka “skills”) for your tasks

• Thread-Based Details: Clean main messages with verbose tool details in threads

I also looked into its source code and found this below function that has core features:

function createSlackContext(event: SlackEvent, slack: SlackBot, state: ChannelState, isEvent?: boolean) {
 
  message: {
   text: event.text,
   rawText: event.text,
   user: event.user,
   userName: user?.userName,
   channel: event.channel,
   ts: event.ts,
   attachments: (event.attachments || []).map((a) => ({ local: a.local })),
  },
  channelName: slack.getChannel(event.channel)?.name,
  store: state.store,
  channels: slack.getAllChannels().map((c) => ({ id: c.id, name: c.name })),
  users: slack.getAllUsers().map((u) => ({ id: u.id, userName: u.userName, displayName: u.displayName })),
 
  respond: async (text: string, shouldLog = true) => {
   ...
  },
 
  replaceMessage: async (text: string) => {
   ...
  },
 
  respondInThread: async (text: string) => {
   ...
  },
 
  setTyping: async (isTyping: boolean) => {
   ...
  },
 
  uploadFile: async (filePath: string, title?: string) => {
   await slack.uploadFile(event.channel, filePath, title);
  },
 
  setWorking: async (working: boolean) => {
   ...
  },
 
  deleteMessage: async () => {
   ...
  },
 
}

This is in packages/mom/src/main.ts.
