Can I target just a single channel?

Absolutely. You can provide a specific Slack channel ID (e.g., C01234567) to mark only that specific channel as read.

Can I mark all Slack channels as read at once?

Yes, by invoking the skill without a specific channel ID, Claude will initiate a bulk process to mark all unread channels as read after you provide confirmation.

Is there a safety check before messages are marked as read?

Yes, the workflow explicitly includes a confirmation step where Claude asks if you are sure you want to proceed before executing the Python script.

Does this skill require specific setup in my repository?

Yes, it requires the slack_message.py script found in the shiiman-slack plugin repository and appropriate Slack API permissions.

Collaboration Tools

Automates the process of marking Slack channels as read, either individually or in bulk, to maintain a clean workspace.

The Slack Unread Marker skill empowers Claude to manage your Slack notification state directly from the terminal. It can efficiently clear unread indicators for specific channels or perform a workspace-wide 'mark all as read' operation. To ensure accuracy and prevent the loss of important context, the skill includes a mandatory confirmation step before any action is taken. This tool is ideal for developers and teams who need to quickly declutter their communication channels and refocus on their primary tasks without manual clicking.
