Clear outdated GitHub Actions caches
Keep builds moving when cache problems start creating repeated failures or confusing local fixes.
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actions caches from a repository matching a specific `key` and an optional git `ref`, used to manage storage or clear outdated/corrupted caches; the action succeeds even if no matching caches are found to delete.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
A stale cache can make a simple build failure feel mysterious and trigger avoidable debugging loops.
- Reduces cache-related build failures
- Avoids emergency cleanup sessions
- Keeps maintenance predictable
Setup
Build it in a few focused steps.
- 1Connect GitHub to Notis once through the portal; connect 2chat if you want notifications in WhatsApp.
- 2Create the automation in the portal or ask Notis conversationally.
- 3Use this instruction: Every week, clear the GitHub Actions cache for the specified repository and cache key when it is older than our retention window or known to be corrupted.
- 4Choose a recurring schedule and report channel, then test with one approved cache key.
Questions about this workflow
Can this target a specific branch cache?
Yes. Include the repository, cache key, and optional Git ref in the instruction.
How often should cache cleanup run?
Weekly is a practical default, with more frequent checks for high-volume repositories.

Supported Triggers and Actions
Notis builds workflows that link 2chat to GitHub. A trigger fires from one place; an action lands in another.
2chat triggers
GitHub actions
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
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.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
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.
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.
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.
