Slack Blameless Bot

The Blameless Bot allows users to easily orchestrate incidents with less toil and provides a comprehensive framework to speed up incident resolution and data collection.

Getting Started

We recommend you first read through our quick start guide to learn some of the bot fundamentals.

Incidents through Slack

With the Blameless bot installed, users can start an Incident through Slack by running Blameless “slash” commands.

When the user runs /blameless start incident a modal will pop up asking the user to select an incident type, the severity level, and add a brief description of the incident. Any configurations made for Incident Types and Severity Namings will be populated in the Incident Creation modal as options.

Slack Incident Titles and Descriptions

Slack supports Incident Titles and Descriptiosn as separate field values. Refer to the Slack commands section for more information.

Task List Updates

Blameless is limiting the Severity Label display length for Slack. The user can add more than 75 characters, but the Slack Label truncates at 75 characters in the dropdown.

Understanding Slackbot Actions

The Blameless Bot has undergone some updates to improve and clarify the actions involved.

Silent Mode Reply Threads

Silent Mode's replies are applied as threads to the incident in question.

BoAssigned User Task Grouping


Tasks are grouped by assigned user, with required tasks being tagged with an asterick, and if they have links, they are so displayed as containing a link.

BoAssigned Tasks

Assigned User

The assigned user can now see all of their tasks grouped together at once.

Task List Updates

Task Lists

The Task list will update as a task is completed or roles are assigned.


Marking non-assigned tasks as complete in Slack cannot be done (by design) (as expected), even though Slack allows anyone to “check” a check box item--implying the task has been completed.

Non-assigned tasks cannot be completed before first being assigned to a user/role. You must assign a user/role to the task first. After you assign a user/role to a task, the assignee can check the task to complete it. The task description changes to strikethrough in the window, which is the indication that the task is completed.

If you attempt to complete a non-assigned task in the Slack Incident Channel, you will be able to check it, however, it will be followed by an error message appearing at the bottom of the list of tasks.

You may need to scroll down the list of tasks to be able to see this error message and in the Task list, the task remains checked, but the description no longer has the strikethrough.

Note that the task check box will remain checked until you leave the channel and come back into the incident channel (refreshing the channel). If you do so, you will see that the task is actually still incomplete (unchecked).


You can enable and disable reminders. When disabling the reminders, you can specify for how long (in days).

/blameless disable reminders for <*X*> days

If you do not include a number of days in the slash command, you will be prompted by the bot.

The number of days to disable retrospective reinders for. Zero disables indefinitely.

Click on the "Submit" button after entering a numeric value.

You will also be notified by the Bot that:

Reminders are currently disabled. If you want to enable reminders press the "Enable" button, referencing the "Enable Reminders" button to the right of the sentence.

Enter the following to reactivate reminders:

/blameless enable reminders.

Task List Updates

If you wish to permanently disable reminders use the following: /blameless disable reminders for 0 day

It is reversible using the Enable slash command however.

Follow up actions within Slack

The /blameless followup command allows users to choose the appropriate Jira project as opposed to a default project.

  1. Select a Jira Project
  2. Select a Jira Issue type
  3. Other required fields may appear depending on the select Jira Project and issue type
  4. Click Save
Supported Blameless fields in the selected JIRA project

When unsupported fields are detected, a warning message is displayed listing the list of unsupported fields. In this case you should select a different Jira issue and/or Jira project which provides supported fields or contact your Jira administrator to make those fields not required.

  1. Close if you decide to not create a follow up action at this time. or
  2. Select a different issue type, or choose another project which has only supported fields.

Refer to the Slack commands section for more information.


With the Blameless Slackbot swimlanes feature, you can minimize customer impact and get to resolution faster.

  • When a complex incident hits, you can kick off parallel streams of investigation to get to the root cause faster
  • Assign roles and create ad hoc tasks to delegate responsibilities and stay on top of critical incident progress

The Slack "/" Swimlane commands, along with the other available slash commands, appear in the following section.

Refer to the Slack Swimlanes Guide for more information.
