Add required status checks when a code freeze is starting soon
A code freeze only works if everyone remembers to enforce it, and someone always forgets. When your freeze window is minutes from starting, Notis adds the extra required status checks to your protected branch, so the guardrails go up on time without a manual scramble.
Trigger
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.
Action
Add status check contexts
Adds status check contexts (provided in the request body, e.g., `{"contexts": ["new-context"]}`) to a protected branch, requiring these contexts to have been previously reported.
Why this helps
Enforcing a freeze depends on someone manually tightening branch protection at the right moment, which is exactly when everyone is busy.
- Freeze guardrails go up exactly when the window begins.
- Removes the human step that always gets forgotten.
- Keeps risky merges out during sensitive periods.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and GitHub to Notis once in the portal.
- 2Tell Notis: When my code freeze event is about to start, add the extra required status checks to the protected main branch.
- 3Select the Google Calendar event starting soon trigger.
- 4Choose a channel where Notis confirms the checks were added.
- 5Test with a sample freeze event and verify the protection tightens.
Questions about this workflow
Do the status checks need to exist first?
Yes. GitHub requires the contexts to have been previously reported before they can be required.
Can I loosen them again later?
You can run a separate automation or ask Notis to adjust branch protection when the freeze ends.
Which branch does it protect?
Whichever protected branch you name in your plain-language prompt.

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.
