Automated Mastodon Post Preflight Checks
Every Monday, WebRun opens Mastodon, reads every post scheduled for the week ahead, checks each one for missing image alt text, the wrong visibility setting, or a missing content warning, files the checklist in Google Drive, and texts you the posts that need a fix.
How do I check scheduled Mastodon posts before they publish?
WebRun opens Mastodon every Monday and reads every post scheduled for the week ahead, checking each one for missing image alt text, the wrong visibility setting, or a missing content warning. It files the checklist in Google Drive and texts you through Twilio, so problems are fixed before publishing.
- Every scheduled image goes out with alt text
- Visibility mistakes get caught before a post publishes
- A weekly checklist history that shows recurring misses

How is each run configured?
Secure by default
Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Will it post or edit anything on my account?
No. WebRun reads your scheduled queue and reports what needs fixing. It never publishes a post, edits a draft, or changes a visibility setting, so you make every change yourself.
What exactly does it check?
Three things on every scheduled post: whether each image has alt text, whether the visibility matches what you set for that kind of post, and whether a content warning is present where your rules require one.
Will it text me every Monday?
Only when something in the queue needs a fix. A clean week is filed to Drive quietly and no text is sent, so a message always means there is work to do.
