Codex + AgentReacher
Codex can ship the launch post too.
AgentReacher's MCP server plugs into Codex. The same agent that wrote the diff can now draft, schedule, and ship the launch tweet.
One agent, code and posts
If Codex shipped the feature, Codex can ship the announcement.
Native MCP
Add AgentReacher to Codex's MCP config. Tools register automatically.
Repo-aware drafts
Codex reads the diff or PR and drafts a launch post that actually describes what shipped.
Voice-matched output
Past posts inform tone so changelog tweets still sound like you.
Schedule from the agent
'Queue a thread about this PR for tomorrow at 9am' - no context switch.
Every platform
Bluesky, X, Threads, LinkedIn, Instagram, TikTok, YouTube, Facebook, Pinterest.
Confirm before publishing
Every publishing tool call goes through a confirm step. Nothing ships without your sign-off.
