Publish and schedule to TikTok, Instagram, YouTube, LinkedIn, X, Bluesky, Mastodon, Facebook, Threads, Reddit, Telegram and Discord through one PostWire API call — writing a separate, native version of the post for each network instead of sending identical text everywhere. Use when the user wants to publish or schedule one idea across several platforms, wants per-network captions, or wants to know why a post was rejected before it is sent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PostWire Publish one idea to many social networks, with a **different post written for each one**. Accounts are connected once through OAuth in the PostWire dashboard, so there is no per-platform developer app, review queue, or token refresh to maintain. One API key covers every network. ## When to Use This Skill - The user wants the same idea published to several networks, but written properly for each - The user wants a post scheduled for later, or a week of posts queued from one topic - The user asks why a post failed, or whether a post *will* fail before sending it - The user is publishing video to TikTok or YouTube from an automation ## What Makes This Different Most multi-posting APIs take one string and send it to every platform. That reads badly and gets suppressed: a LinkedIn post written like a tweet performs like neither. PostWire has a `/api/generate` step that writes a caption per network — length, tone, hashtags and link handling — from a single prompt, which you then pass to publish or schedule. It also **refuses posts that are going to fail**, before they are queued rather than after the platform rejects them: | network | requires | |---|---| …

How to install
mdr add davepoon/buildwithclaude/postwire@sha256:d92a2374d5f89dbbThe line at the top of this page pins the label git:20260831.87d0fbf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
