Summary

Allow different chats to use different working directories, so each chat can have its own CLAUDE.md with specific instructions and tool configurations.

Config Schema Addition

In config.ts:

cwdOverrides?: Record<string, string>; // Per-sender/group cwd overrides
contacts?: Record<string, string>;     // Phone number to display name mapping

With zod:

cwdOverrides: z.record(z.string(), z.string()).optional(),
contacts: z.record(z.string(), z.string()).optional(),

Example Config

{
  "cwdOverrides": {
    "+1234567890": "/home/user/chats/personal",
    "+0987654321": "/home/user/chats/work", 
    "[email protected]": "/home/user/chats/project-alpha"
  },
  "contacts": {
    "+1234567890": "Alice",
    "+0987654321": "Bob"
  }
}

Implementation in reply.ts

const cwdOverrides = cfg.cwdOverrides ?? {};
const customCwd = sessionKey ? cwdOverrides[sessionKey] : undefined;
const commandReply = {
  ...reply,
  command: reply.command,
  mode: "command" as const,
  cwd: customCwd ?? reply.cwd,
};

Directory Structure

Each chat directory contains its own CLAUDE.md with chat-specific instructions and tool configurations:

/home/user/chats/
├── personal/
│   └── CLAUDE.md    # Personal assistant + personal MCP tools
├── work/
│   └── CLAUDE.md    # Work instructions + work MCP tools
└── project-alpha/
    └── CLAUDE.md    # Project context + project MCP tools

Example CLAUDE.md with Per-Chat MCP Tools

Each chat's CLAUDE.md can document its own MCP server configuration. For example, a project group chat might have:

# Project Alpha - AI Assistant

You are an assistant for the Project Alpha team.

## MCP Tools

This chat has access to project-specific tools via mcporter:

### List Available Tools
```bash
MCPORTER_CONFIG=~/config/mcporter-chats/project-alpha.json mcporter list

Query Project Database

MCPORTER_CONFIG=~/config/mcporter-chats/project-alpha.json mcporter call 'postgres.query(sql: "SELECT * FROM tasks")'

Browse & Screenshot

MCPORTER_CONFIG=~/config/mcporter-chats/project-alpha.json mcporter call 'chrome-devtools.navigate(url: "https://example.com")'

With a corresponding mcporter config at `~/config/mcporter-chats/project-alpha.json`:

```json
{
  "mcpServers": {
    "postgres": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://..."]
    },
    "chrome-devtools": {
      "command": "npx", 
      "args": ["-y", "chrome-devtools-mcp@latest", "--headless"]
    }
  }
}

Use Case

Running a multi-purpose AI assistant where:

• Personal chats have personal tools (spotify, home automation)
• Work chats have work tools (email, calendar, CRM)
• Project group chats have project-specific tools (databases, deployment)
• Each chat has tailored instructions via its own CLAUDE.md
