Stop one known blocker with a bounded action and an honest result.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Cancel a workflow run
Cancels a workflow run in a github repository if it is in a cancellable state (e.g., 'in progress' or 'queued').
Why this helps
A stalled workflow consumes attention while everyone waits for someone to intervene.
- Targets one exact run instead of broad cleanup.
- Requires trusted requester and explicit cancellation approval.
- Reports when GitHub cannot cancel the current state.
Setup
Build it in a few focused steps.
- 1Connect Slackbot and GitHub once in Notis.
- 2Create an automation that cancels only the supplied workflow run after an allowlisted requester approves the escalation.
- 3Choose channel messages, select a report channel, and test with one real queued run.
Questions about this workflow
Will it cancel every run in a repository?
No. The instruction must require one exact repository and workflow run id.

Supported Triggers and Actions
Notis builds workflows that link Slackbot to GitHub. A trigger fires from one place; an action lands in another.
Slackbot triggers
GitHub actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
List repositories starred by the authenticated user
Deprecated: lists repositories starred by the authenticated user, including star creation timestamps; use 'list repositories starred by the authenticated user' instead.
New Channel Created Trigger
Triggered when a new channel is created in Slack.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Add email for auth user
Adds one or more email addresses (which will be initially unverified) to the authenticated user's github account; use this to associate new emails, noting an email verified for another account will error, while an existing email for the current user is accepted.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Add app access restrictions
Replaces github app access restrictions for an existing protected branch; requires a json array of app slugs in the request body, where apps must be installed and have 'contents' write permissions.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Add a repository collaborator
Adds a github user as a repository collaborator, or updates their permission if already a collaborator; `permission` applies to organization-owned repositories (personal ones default to 'push' and ignore this field), and an invitation may be created or permissions updated directly.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
Add a repository to an app installation
Adds a repository to a github app installation, granting the app access; requires authenticated user to have admin rights for the repository and access to the installation.
