Publish a vetted post to an X (Twitter) account through the owner's real logged-in Chrome tab, rate-guarded and draft-first. Counts length the way X does, treating every link as 23 characters, and refuses over-limit text instead of silently truncating. Triggers: "/x-post", "tweet this", "post to X".
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
# /x-post — post to X from the owner's account (Chrome, draft-first) **Why.** EN teasers (from /episode) kept piling up as drafts — there was no poster for X. Same safe pattern as /fb-post: a live logged-in tab, never headless. ## 0. Safety catch (mandatory) ```bash python "$USERPROFILE/.claude/scripts/_shared/social_guard.py" check x --text "<final text>" ``` `BLOCKED` (exit 3) → STOP and report (the 6/day limit, or a duplicate). Do not work around it. ## 1. The text (the owner's voice, top model) Take a ready draft (an /episode EN teaser or an intention-lane text) or write it with the top model. A single tweet is ≤280 characters — count BEFORE opening the browser; longer → a thread (each tweet ≤280, chained by reply) or offer the operator a shorter version. ## 2. Tier-2 gate (draft-first) Show the final text (+ the thread split, if it is a thread) → wait for an explicit `+`. Nothing is published without it. ## 3. The browser (Claude-in-Chrome, a live tab) > Browser work stays local on this machine; never drag the window to the foreground elsewhere. …

How to install
mdr add tonydzi/second-brain-starter-kit/x-post@sha256:86f7e93b71463ec1The line at the top of this page pins the label git:20260908.2ec1bf8, 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.
