Crier — Development skill for Claude Code

Crier

Cross-post your content to dev.to, Ghost, WordPress, Hashnode, Medium, Bluesky, Mastodon, Threads, Telegram, Discord, and more.

Like a town crier announcing your content to the world.

Getting Started

Quick Setup

pip install crier
cd your-blog
crier init

The `init` command walks you through:

• Creating the SQLite registry at ~/.config/crier/crier.db
• Detecting your content directories
• Configuring platforms with API keys

How It Works

1. Your markdown posts with YAML front matter are the source of truth
2. SQLite registry at ~/.config/crier/crier.db tracks what's published where (slug-keyed)
3. crier audit shows what's missing from which platforms
4. crier publish or audit --publish publishes content

# See what needs publishing
crier audit

# Publish a file to a platform
crier publish post.md --to devto

# Publish to multiple platforms
crier publish post.md --to devto --to bluesky --to mastodon

# Bulk publish missing content (interactive)
crier audit --publish

With Claude Code

Crier is designed to work with Claude Code for AI-assisted publishing. Install the crier plugin from the queelius-plugins marketplace, which provides a skill, a `/crier` slash command, a cross-poster agent, and an MCP server exposing the registry to Claude. Then ask naturally:

• "Cross-post my latest article to all platforms"
• "What articles haven't been published to Bluesky?"
• "Publish this post to Mastodon with a good announcement"

The MCP server (`crier mcp`) gives Claude direct query access to the registry, and the cross-poster agent can handle bulk publishing autonomously with rewrites for short-form platforms.

Installation

pip install crier
