Clear a GitHub Actions cache after a confirmed cache bug
Turn a confirmed cache diagnosis into cleanup from the same Linear conversation, without breaking focus to find the repository cache controls.
Trigger
Public Team Comment Created
Fires when a new comment is posted on a *public-team* Linear issue. For private teams (lock icon in Linear's sidebar) use `LINEAR_PRIVATE_TEAM_COMMENT_CREATED`.
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actions caches from a repository matching a specific `key` and an optional git `ref`, used to manage storage or clear outdated/corrupted caches; the action succeeds even if no matching caches are found to delete.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
Once a stale cache is identified, the fix can still wait because clearing it requires a separate GitHub detour and a precise key.
- Speeds recovery from known cache failures
- Keeps cleanup tied to an explicit diagnosis
- Avoids searching GitHub settings mid-debug
Setup
Build it in a few focused steps.
- 1Connect Linear and GitHub to Notis once.
- 2Describe the authorized comment pattern and how it identifies the repository, cache key, and optional Git reference.
- 3Select the public team comment created trigger and choose a channel for run reports.
- 4Test with a disposable cache key in a safe repository.
Questions about this workflow
What if no cache matches the key?
GitHub treats the deletion request as successful even when no matching cache is found.
Can the workflow target one branch?
Yes. Your instruction can include an optional Git reference along with the cache key.

Supported Triggers and Actions
Notis builds workflows that link Linear to GitHub. A trigger fires from one place; an action lands in another.
Linear 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.
Comment Received Trigger
Triggered when a comment is received.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Issue Created Trigger
Triggered when a new issue is created.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Issue Updated Trigger
Triggered when an issue is updated. For example labels are changed, issue status is changed, etc.
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.
Private Team Comment Created
Fires when a new comment is posted on an issue in a private Linear team (polled with the connected user's token).
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.
Private Team Issue Created
Fires when a new issue appears in a private Linear team (polled with the connected user's token).
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.
Private Team Issue Properties Updated
Fires when properties on an issue change in a private Linear team (polled with the connected user's token).
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.
Linear and GitHub, or any other combination from 1,000+ integrations.
