Clear a GitHub Actions cache key
Remove stale build state without turning routine troubleshooting into a scavenger hunt.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Clear repository cache by key
Deletes github actions caches from a repository matching a specific `key` and an optional git `ref`, used to manage storage or clear outdated/corrupted caches; the action succeeds even if no matching caches are found to delete.
Why this helps
Corrupted caches create repeat failures and consume attention during debugging.
- Targets a named key and optional ref.
- Requires explicit cleanup authorization.
- Reports that no matching cache was found without overstating impact.
Setup
Build it in a few focused steps.
- 1Connect Slackbot and GitHub once in Notis.
- 2Create an automation that clears only the cache key and optional ref named in an approved troubleshooting request.
- 3Choose Slackbot DMs, select a report channel, and test with one known stale key.
Questions about this workflow
Does clearing a cache guarantee the build will pass?
No. Notis reports the cache action result; later build success must be checked separately.

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.
Connect any two apps with Notis in the middle.
Not just Slackbot and GitHub. Any combination from 1,000+ integrations.
