Clear GitHub Actions caches on a recurring schedule
Flaky builds from a stale cache are the kind of problem that eats an afternoon and teaches you nothing. Notis clears your GitHub Actions caches by key on a schedule you set, so corrupted or outdated caches get cleaned out before they can cost you.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
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actions caches from a repository matching a specific `key` and an optional git `ref`, used to manage storage or clear outdated/corrupted caches; the action succeeds even if no matching caches are found to delete.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
Stale caches cause mysterious build failures, and remembering to clear them by hand is exactly the kind of maintenance chore that never happens.
- Stale caches get cleaned before they break a build.
- Turns an easily-forgotten chore into a hands-off routine.
- Frees you from debugging failures that were never really about your code.
Setup
Build it in a few focused steps.
- 1Connect GitHub to Notis once in the portal.
- 2Create the automation by telling Notis: Every night, clear the GitHub Actions caches matching my build key.
- 3Pick the recurring schedule trigger and set your preferred time.
- 4Choose a channel where Notis reports what it cleared.
- 5Run it once manually to confirm the right caches are removed.
Questions about this workflow
What if there are no matching caches?
The action succeeds even when nothing matches, so the run stays clean.
Can I scope it to a branch?
Yes. Mention the git ref in your prompt and Notis limits the clear to that ref.
How often can it run?
Any recurring schedule you like, from nightly to weekly.

Supported Triggers and Actions
Notis builds workflows that link Google Calendar to GitHub. A trigger fires from one place; an action lands in another.
Google Calendar triggers
GitHub actions
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
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.
Event Starting Soon
Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Calendar Event Changes
**SOON TO BE DEPRECATED** - Use Calendar Event Sync (polling trigger) instead. Real-time webhook trigger for calendar event changes. Returns event metadata only. For full event data, use Calendar Event Sync (polling trigger).
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
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.
Calendar Event Sync
Polling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook).
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.
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
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.
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 Google Calendar and GitHub. Any combination from 1,000+ integrations.
