Make incremental PR changes easy to follow
Each new commit can come with a clear explanation of what moved and why.
Trigger
New Commit Added to Pull Request
Triggers when a new commit is pushed to a specific pull request. Monitors all commits on the specified pull request and emits an event for each newly added commit. This covers force-pushes and additional commits pushed to the PR's head branch.
Action
Generate a Gamma
Create a new gamma generation. use to produce an ai-generated presentation/content. docs: https://developers.gamma.app/reference/generate-a-gamma
Why this helps
Reviewers lose time rechecking the entire pull request after every update.
- Reduce repeated review effort
- Highlight changes since the last checkpoint
- Keep asynchronous collaborators aligned
Setup
Build it in a few focused steps.
- 1Connect GitHub and Gamma to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to create it in plain language.
- 3Instruct Notis to create a Gamma progress deck whenever a new commit is added to a pull request, focusing on changes since the prior review, remaining concerns, and requested feedback.
- 4Pick the new PR commit trigger, choose the reporting channel, and test with one updated pull request.
Questions about this workflow
Is it triggered for every commit?
Yes, when configured for the monitored pull request, each newly added commit can produce a progress summary.
Can it avoid low-value implementation detail?
Ask Notis to focus on behavior, risk, and review relevance.

Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.

Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
