Preview Markdown from a reaction
Use a deliberate reaction on a draft message to check its Gitea-rendered HTML before someone copies it into a repository document.
Trigger
Message Reaction Added
Triggers when a reaction is added to a message.
Action
Render Markdown
Convert a Markdown document to HTML for display.
Why this helps
Formatting problems are easy to miss in a plain Slack draft.
- Inspect rendered output before reuse
- Keep preview requests low-friction
Setup
Build it in a few focused steps.
- 1Connect Slack and Gitea to Notis once in the portal.
- 2Ask Notis to create an automation, or open Automations → New Automation in the portal.
- 3Use this plain-language prompt: “When the designated preview reaction is added to a draft in the agreed channel, render that message as Gitea Markdown in the intended context and report a safe preview; do not publish the draft.”
- 4Choose the Slack reaction added trigger and a channel for run reports; create it and test with one real example.
Questions about this workflow
Does this edit a README or issue?
No. Rendering returns HTML; it does not write repository content.
