WeChat Publishing Pipeline Built for Coding Agents

What it does

md2wechat is a Go CLI that ingests Markdown and emits WeChat Official Account-compatible HTML, optionally pushing it straight to the platform’s draft box. It bundles a complete content pipeline: AI-assisted drafting, a humanize pass to strip obvious AI tells, cover-image generation, and multi-account management. All commands can emit JSON envelopes, so the tool is scriptable from the start.

The interesting bit

The tool treats coding agents as first-class users. It exposes discovery endpoints—capabilities, layout list, themes list—that return structured JSON for agents to consume, and the README explicitly warns against dumping the whole catalog into a context window. The :::module syntax for 43 layout components is a deliberate design system rather than a prompt hack, though it is locked behind a paid API tier.

Key highlights

• Deterministic API mode renders identical HTML from the same Markdown, which matters for brand consistency and automated pipelines.
• 40 WeChat-tuned themes and 43 structured layout modules (:::hero, :::timeline, etc.) that survive the platform’s idiosyncratic renderer.
• Built-in humanize command to rewrite AI-generated copy so it sounds less like a language model.
• Agent-native JSON output and discovery endpoints designed for Claude Code, Codex, and OpenClaw integration.
• Free “AI mode” generates styling prompts for external LLMs but only offers 3 themes and non-deterministic output.

Caveats

• The full feature set (40 themes, 43 layout modules, deterministic output) requires a paid API key; the free tier is essentially a prompt generator.
• AI image generation and multi-account management are advertised, but the README is vague on provider details, costs, and rate limits.
• The tool is tightly coupled to WeChat’s proprietary platform, so it is useless if you are not publishing there.

Verdict

Grab it if you run a WeChat Official Account and want to automate publishing from a terminal or agent. Skip it if your audience lives anywhere else on the internet.
