/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)

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. ⛔ IP gate (2026-07-16): posting to X and other ban-sensitive social platforms happens ONLY from the hub HUB-1 (a stable IP). Do NOT post from another machine — send the task to the hub as text. Canon: the "IP-sensitive actions from the hub only" rule.

1. list_connected_browsers → no extension → block and tell the operator (do not fall back to Playwright).
2. Open the x.com tab. Verify the logged-in handle (avatar / profile menu) against the registry. A different account → STOP and ask. Not logged in → block (we never touch login/2FA on X — checkpoint risk).
3. Composer: find "post composer / What's happening". Enter the text (form_input). Do not press Post until the gate in §2 is satisfied.
4. After the + — press Post. For a thread: use the "+" button in the composer after the first tweet, or reply to your own tweet.
5. A screenshot of the published post + the tweet URL (click the timestamp → address bar) is the proof.

4. Record it (AFTER a successful publication)

python "$USERPROFILE/.claude/scripts/_shared/social_guard.py" record x --text "<text>"

Report: the link + the screenshot + "x today N/6".

Stop switches

• Any checkpoint / captcha / "unusual activity" from X → STOP immediately, report, zero retries.
• Never republish identical text; never post from someone else's account.
• Links in the text must be live and ours (link-safety).
