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
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Render Markdown
Tool to render a markdown document as HTML with configurable rendering modes and context. Use when you need to convert markdown to HTML with specific rendering contexts like comments, wiki pages, or files.
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a draft in the agreed channel, render that message as Gitea Markdown in the intended context and report a safe preview; do not publish the draft.”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.
