Agent Channel

A TypeScript CLI tool that enables AI agents and humans to interact with Channel Talk workspaces through a simple command interface. Features zero-config credential extraction from the Channel Talk desktop app (with browser fallback) and multi-workspace support.

Key Concepts

Before diving in, a few things about Channel Talk's terminology:

• Channel = workspace (not a chat channel like Slack). The API calls it a "channel," but it means your entire workspace.
• UserChats = 1:1 conversations with end users (customers).
• Groups = team inbox channels (similar to Slack channels). Referenced by ID.
• DirectChats = direct messages between managers.
• Managers = human agents on your team.
• Bots = automated agents in the workspace.
• Messages use a blocks format: [{ type: "text", value: "..." }]. The CLI handles this automatically when you pass plain text.

Quick Start

# Get workspace snapshot (credentials are extracted automatically)
agent-channeltalk snapshot --pretty

# Send a message to a group
agent-channeltalk message send group grp_abc123 "Hello from the CLI!"

# Send a message to a user chat
agent-channeltalk message send user-chat uc_abc123 "Thanks for reaching out!"

# List user chats
agent-channeltalk chat list

Authentication

Credentials are extracted automatically from the Channel Talk desktop app (or Chromium browser as fallback) on first use. No manual setup required, no API keys needed. Just run any command and authentication happens silently in the background.

The Channel Talk desktop app stores auth cookies in a SQLite database. On macOS, cookies are plaintext and no Keychain prompt is needed. On Windows, cookies are DPAPI-encrypted and decrypted automatically. When falling back to a Chromium browser on macOS, cookies require Keychain decryption. The CLI reads two cookies:

• x-account (JWT) - your account identity
• ch-session-1 (JWT) - your session token

These cookies expire after roughly 30 days. When they expire, the CLI automatically re-extracts fresh cookies from the desktop app or browser on the next command.

IMPORTANT: Always use agent-channeltalk auth extract to obtain credentials. The CLI extracts from the desktop app first, falling back to Chromium browsers if the app isn't installed.

Multi-Workspace Support

If you're logged into multiple Channel Talk workspaces, all are discovered automatically. The first workspace is selected by default.

# List all available workspaces
agent-channeltalk auth list

# Switch to a different workspace
agent-channeltalk auth use <workspace-id>

# Check auth status
agent-channeltalk auth status

# Remove a stored workspace
agent-channeltalk auth remove <workspace-id>

Memory

The agent maintains a ~/.config/agent-messenger/MEMORY.md file as persistent memory across sessions. This is agent-managed, the CLI does not read or write this file. Use the Read and Write tools to manage your memory file.

Reading Memory

At the start of every task, read ~/.config/agent-messenger/MEMORY.md using the Read tool to load any previously discovered workspace IDs, group IDs, chat IDs, manager IDs, and preferences.

• If the file doesn't exist yet, that's fine. Proceed without it and create it when you first have useful information to store.
• If the file can't be read (permissions, missing directory), proceed without memory. Don't error out.

Writing Memory

After discovering useful information, update ~/.config/agent-messenger/MEMORY.md using the Write tool. Write triggers include:

• After discovering workspace IDs and names (from auth list, snapshot, etc.)
• After discovering group IDs and names (from group list, snapshot, etc.)
• After discovering chat IDs (from chat list, etc.)
• After discovering manager IDs and names (from manager list, etc.)
• After discovering bot names (from bot list, etc.)
• After the user gives you an alias or preference ("call this the support workspace", "my main group is X")

When writing, include the complete file content. The Write tool overwrites the entire file.

What to Store

• Workspace IDs with names
• Group IDs with names
• UserChat IDs with context
• Manager IDs with names
• Bot IDs with names
• User-given aliases ("support workspace", "billing group")
• Any user preference expressed during interaction

What NOT to Store

Never store cookies, tokens, credentials, or any sensitive data. Never store full message content (just IDs and context). Never store personal user data.

Handling Stale Data

If a memorized ID returns an error (chat not found, group not found), remove it from MEMORY.md. Don't blindly trust memorized data. Verify when something seems off. Prefer re-listing over using a memorized ID that might be stale.

Format / Example

# Agent Messenger Memory

## Channel Talk Workspaces

- `abc123` - Acme Support

## Groups (Acme Support)

- `grp_111` - Support Inbox
- `grp_222` - Billing Inbox
- `grp_333` - Engineering

## Recent UserChats (Acme Support)

- `uc_aaa` - John Doe inquiry (opened)
- `uc_bbb` - Refund request (closed)

## Managers (Acme Support)

- `mgr_001` - Alice (Team Lead)
- `mgr_002` - Bob (Support Agent)

## Bots (Acme Support)

- `bot_001` - Support Bot
- `bot_002` - Notification Bot

## Aliases

- "support" -> `grp_111` (Support Inbox in Acme Support)

## Notes

- User prefers --pretty output for snapshots
- Main workspace is "Acme Support"

Memory lets you skip repeated group list and chat list calls. When you already know an ID from a previous session, use it directly.

• Managers (id, name, email)
• Bots (id, name)

Output Format

JSON (Default)

All commands output JSON by default for AI consumption:

{
  "id": "msg_abc123",
  "channel_id": "ch_def456",
  "chat_id": "uc_ghi789",
  "chat_type": "user-chat",
  "person_type": "manager",
  "plain_text": "Hello world",
  "created_at": 1705312200000
}

Pretty (Human-Readable)

Use --pretty flag for formatted output:

agent-channeltalk group list --pretty

Global Options

Option	Description
--pretty	Human-readable output instead of JSON
--workspace <id>	Use a specific workspace for this command

Common Patterns

See references/common-patterns.md for typical AI agent workflows.

Templates

See templates/ directory for runnable examples:

• post-message.sh - Send messages with error handling
• monitor-chat.sh - Poll for new UserChats
• workspace-summary.sh - Generate workspace summary

Error Handling

All commands return consistent error format:

{
  "error": "No credentials. Run \"agent-channeltalk auth extract\" first."
}

Common errors: No credentials, Workspace not found, Invalid --limit value.

Configuration

Credentials stored in ~/.config/agent-messenger/channel-credentials.json (0600 permissions). See references/authentication.md for format and security details.

Config format:

{
  "current": { "workspace_id": "abc123" },
  "workspaces": {
    "abc123": {
      "workspace_id": "abc123",
      "workspace_name": "Acme Support",
      "account_id": "acc_001",
      "account_name": "Alice",
      "account_cookie": "...",
      "session_cookie": "..."
    }
  }
}

Feature Comparison: agent-channeltalk vs agent-channeltalkbot

Feature	agent-channeltalk (user)	agent-channeltalkbot (bot)
Auth method	Auto-extract cookies	API key + secret
Setup required	None (zero-config)	Manual key setup
Acts as	You (manager)	Bot identity
Send messages	✅	✅
List messages	✅	✅
Search messages	✅	-
Close/delete chats	-	✅
Create/delete bots	-	✅
Set default bot	-	✅
Group @name references	-	✅
Direct chat support	✅	-
Multi-workspace	✅	✅
CI/CD friendly	-	✅

Use agent-channeltalk when you want zero-config access acting as yourself. Use agent-channeltalkbot for server-side automation, CI/CD pipelines, or when you need bot-specific features like closing chats.

Limitations

• Desktop app extraction: macOS and Windows. Browser fallback: macOS, Linux, and Windows.
• No real-time events / WebSocket connection
• No file upload support
• No message editing or deletion
• No chat close/delete (use agent-channeltalkbot for chat management)
• No bot creation/deletion (use agent-channeltalkbot for bot management)
• No @name group references (use group IDs from group list)
• Plain text messages only (no rich blocks in v1)
• Cookies expire after ~30 days (auto-re-extracted)

Troubleshooting

agent-channeltalk: command not found

agent-channeltalk is NOT the npm package name. The npm package is agent-messenger.

If the package is installed globally, use agent-channeltalk directly:

agent-channeltalk snapshot --pretty

If the package is NOT installed, run it directly with npx -y:

npx -y agent-messenger channeltalk snapshot --pretty

Note: If the user prefers a different package runner (e.g., bunx, pnpx, pnpm dlx), use that instead.

NEVER run npx agent-channeltalk, bunx agent-channeltalk, or pnpm dlx agent-channeltalk. It will fail or install a wrong package since agent-channeltalk is not the npm package name.

Channel Talk desktop app not found

The CLI looks for the Channel Talk desktop app's cookie database in these locations:

macOS:

1. ~/Library/Containers/com.zoyi.channel.desk.osx/Data/Library/Application Support/Channel Talk/Cookies (Mac App Store version)
2. ~/Library/Application Support/Channel Talk/Cookies (direct download / Electron version)

Windows:

1. %APPDATA%\Channel Talk\Network\Cookies

If none exist, log in to Channel Talk in a supported Chromium browser (Chrome, Edge, Arc, Brave) or install the desktop app and log in.

Cookies expired

Cookies expire after roughly 30 days. The CLI automatically re-extracts on the next command. If auto-extraction fails:

1. Open the Channel Talk desktop app or desk.channel.io in a supported Chromium browser
2. Make sure you're logged in
3. Run agent-channeltalk auth extract

For other troubleshooting, see references/authentication.md.
