Fix CI Cache Issues Without Leaving Slack
When your CI is slow or broken due to a stale cache, just mention it in Slack—Notis clears the cache and rebuilds.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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actions caches from a repository matching a specific `key` and an optional git `ref`, used to manage storage or clear outdated/corrupted caches; the action succeeds even if no matching caches are found to delete.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
Your CI pipeline is stuck because of a corrupted cache. You have to switch to GitHub, find the cache management UI, and clear it. Meanwhile, deployments are blocked.
- Unblock deployments in seconds, not minutes
- No need to navigate GitHub's cache UI
- Stay in Slack while fixing CI issues
Setup
Build it in a few focused steps.
- 1Connect Slack and GitHub to Notis.
- 2Create an automation: 'When someone mentions a cache issue or says 'clear cache' in Slack, clear the GitHub Actions cache for this repository.'
- 3Optionally specify which cache keys or branches to target.
- 4Choose a Notis channel for confirmations.
- 5Test by discussing a cache issue in Slack—Notis will clear it and confirm.
Questions about this workflow
Will this clear ALL caches or just specific ones?
You can target specific cache keys (e.g., 'node_modules'), or clear everything. Specify in your Slack message or during setup.
How long does a cache rebuild take?
The next workflow run will rebuild it from scratch. Duration depends on your build—usually seconds to minutes.
Can I clear cache on a schedule to prevent problems?
Yes. Use the automation with a 'notis_cron' trigger to clear cache weekly or daily, depending on your needs.

Supported Triggers and Actions
Notis builds workflows that link Slack to GitHub. A trigger fires from one place; an action lands in another.
Slack triggers
GitHub actions
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
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.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
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.
Reaction Removed Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_REMOVED` instead. Triggered when a reaction is removed from a message.
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.
New Bot Message Received Trigger
DEPRECATED: use `SLACK_CHANNEL_MESSAGE_RECEIVED` with `is_bot_message=true` instead. Triggered when a new bot message is posted to a Slack channel.
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.
