What

xmaster is an X/Twitter CLI built in Rust. Single binary, ~8MB, JSON output, structured exit codes. It handles posting, replying, threading, search (X API v2 + xAI/Grok), DMs, scheduling, bookmarks, and pre-flight post analysis with real algorithm weights from the open-source X ranking code.

Proposing it as a bundled skill under `skills/xmaster/`. PR: #56764

Why

X/Twitter is a missing channel in OpenClaw. There's no built-in way to post, reply, search, or track engagement. xmaster was built agent-first — `--json` output, semantic exit codes (0/1/2/3/4), and `agent-info` for machine-readable capability discovery.

Already works as a Claude Code skill. The agent shells out to xmaster and gets structured data back.

What it covers

• Post, reply, thread, quote, delete
• Search (X API v2 + xAI semantic search)
• DMs (send, inbox, threads)
• Bookmarks (sync, search, export, digest)
• Scheduling (with launchd daemon)
• Pre-flight analysis (scores posts, catches weak hooks, link penalties, engagement bait)
• Engagement (like, retweet, follow, block, mute)
• Metrics and reporting (daily/weekly digests, timing heatmaps)
• Writing style persistence (agent drafts in your voice)
