Keep GitHub caches tidy with a Knack maintenance rhythm
Small maintenance tasks should not depend on remembering the command.
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actions caches from a repository matching a specific `key` and an optional git `ref`, used to manage storage or clear outdated/corrupted caches; the action succeeds even if no matching caches are found to delete.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 slow troubleshooting and create clutter, but cleanup rarely feels urgent enough to schedule manually.
- Reduces cache-related confusion.
- Keeps maintenance repeatable.
- Frees founders from low-value reminders.
Setup
Build it in a few focused steps.
- 1Connect Knack and GitHub to Notis once through the portal.
- 2Create the automation in the portal or ask Notis conversationally.
- 3Use this instruction: Review Knack maintenance records and clear the specified outdated GitHub repository caches by key and ref.
- 4Choose a recurring trigger, select a reporting channel, and test with one maintenance record.

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.
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.
