markdownToMrkdwn

Overview

markdownToMrkdwn converts GitHub-flavored Markdown — what agents emit — into Slack's mrkdwn dialect. The adapter applies it automatically to every streamed chunk and every Section/Markdown block, so agent output renders correctly without the model knowing about mrkdwn.

Signature

import { markdownToMrkdwn } from "@copilotkit/bot-slack";

function markdownToMrkdwn(input: string): string;

Behavior

• Inline styles — GFM emphasis is rewritten to mrkdwn (e.g. **bold** → *bold*); links become mrkdwn <url|label> form; lists are normalized.
• Code passes through — fenced ``` blocks and inline `code` are left untouched; they render identically in both flavors.
• Tables become monospace — mrkdwn has no table primitive, so GFM tables are column-aligned and wrapped in a code fence to stay readable.
• Applied per chunk — during streaming, the translation runs on each flushed chunk, paired with the mid-stream auto-closer so partially streamed markdown still renders.
