@copilot what about send-message <email|channel> message [reply-to-timestamp]?

Refactored to use send-message <channel|email> <message> [timestamp] as suggested. The timestamp is now an optional third parameter, making the interface simpler. Changes in commit e54e51a:

• Removed separate reply-message command
• Consolidated sendMessage() and replyMessage() into single function
• Updated MCP server to use single send_message tool with optional timestamp parameter
• Updated tests and documentation

CLI Usage:

# Send a message
slack send-message user@example.com "Hello!"

# Reply to a message
slack send-message user@example.com "Thanks!" "1234567890.123456"

Help output:

Usage:
  slack configure                                          - configure Slack token (reads from stdin)
  slack send-message <channel|email> <message> [timestamp] - send a message to a user (optionally as a reply)
  slack mcp-server                                         - start MCP server (Model Context Protocol)

@copilot please address my comment above.

To make it clear, lets call it [thread-ts]. Make it clear in the docs this is for replying to message thread. @copilot

Updated in commit efc3a49. Changed parameter name to [thread-ts] and clarified in documentation that it's for replying to message threads.

CLI Usage:

Usage:
  slack configure                                            - configure Slack token (reads from stdin)
  slack send-message <channel|email> <message> [thread-ts]   - send a message (optionally reply to a thread)
  slack mcp-server                                           - start MCP server (Model Context Protocol)

MCP Tool Parameter:

• thread_ts - Optional: The thread timestamp of the parent message to reply to (e.g., '1234567890.123456'). When provided, the message will be sent as a threaded reply.

Example:

# Reply to a message in a thread (thread-ts is the timestamp of the parent message)
slack send-message user@example.com "Thanks for the feedback!" "1234567890.123456"

@copilot please address my comment above.

Done in commit efc3a49. The parameter is now called [thread-ts] and the documentation clearly states it's for replying to message threads.

@copilot please print the of the message once sent so that the the user can note the and reply to it.

The comment appears to be incomplete. Could you please clarify what you'd like me to print?

@copilot when the message has been sent, print the thread-ts from the response, no the next send-message can continue the thread.

Implemented in commit f067cda. The thread-ts is now printed after every message is sent, allowing you to use it to continue the conversation in a thread.

CLI Output:

$ slack send-message user@example.com "Hello!"
Message sent to user@example.com (U12345678)
thread-ts: 1234567890.123456

$ slack send-message user@example.com "Reply!" "1234567890.123456"
Reply sent to user@example.com (U12345678) in thread 1234567890.123456
thread-ts: 1234567890.654321

MCP Server:
The MCP tool also returns the thread-ts in its response:

Message sent successfully to user@example.com
thread-ts: 1234567890.123456

This allows subsequent messages to continue the thread by using the returned thread-ts.

@copilot this is a bit more complex that I'd like. When sending a message without the thread-ts, you must print the thread-ts. However, if you reply to a thread, do not print the timestamp as it will not change.

Simplified in commit 07b1b1a. The thread-ts is now only printed when sending a new message (without thread-ts parameter), not when replying to a thread.

New message output:

$ slack send-message user@example.com "Hello!"
Message sent to user@example.com (U12345678)
thread-ts: 1234567890.123456

Thread reply output (no thread-ts printed):

$ slack send-message user@example.com "Reply!" "1234567890.123456"
Reply sent to user@example.com (U12345678) in thread 1234567890.123456

MCP Server:

• New message: includes thread-ts in response
• Thread reply: no thread-ts in response
