xmaster — X/Twitter CLI
Run xmaster agent-info --json to get full capabilities, commands, and algorithm intelligence.
Core Workflows
Posting
NEVER post without explicit user approval. Always analyze first.
1. xmaster analyze "text" --goal replies --json # Score it
2. Show user the score/grade and final text
3. Only post after explicit "yes"/"post it"/"go"
4. xmaster post "approved text" --json
Finding Posts to Reply To
Replies are ~20x a like in the 2026 algorithm. This is the #1 growth lever for small accounts.
# Find fresh posts from big accounts in your niche:
xmaster engage feed "longevity biotech" --min-followers 5000 --max-age-mins 60
# Or find accounts to build relationships with:
xmaster engage recommend --topic "longevity" --min-followers 1000
# Search their recent posts (from: operator parsed into hard author filter):
xmaster search-ai "from:username" # Latest posts by user
xmaster search-ai "from:username longevity" # Their posts on a topic
xmaster search-ai "from:user1 from:user2 senolytics" # Multiple authors
Checking Performance
xmaster timeline --user USERNAME --sort impressions -c 50 # Top posts by reach
xmaster timeline --user USERNAME --since 24h # Recent posts
xmaster track followers # New/lost followers
xmaster track growth -d 30 # Follower history
xmaster metrics <id> # Single post deep dive
Algorithm Intelligence (2026)
The CLI embeds knowledge from xai-org/x-algorithm (January 2026). Key facts:
- 19 scoring signals (15 positive, 4 negative) — weights unpublished but estimated
- Top signals: follow-from-post (~30x), reply (~20x), quote (~18x), profile click (~12x)
- Negative signals are predictive — Grok suppresses content it predicts users would block/mute
- Bookmarks are NOT a signal — ignore advice claiming otherwise
- share_via_dm fires when OTHERS share YOUR post — create DM-worthy content, don't DM your own posts
- Author diversity decay — space posts 2+ hours apart
- Engagement history drives everything — dormant accounts need 2 weeks of active engagement before the algorithm works
xmaster analyze checks sentiment (Grok suppresses combative tone), estimates dwell time, and flags algorithm-penalised patterns.
Config
xmaster config set account.premium true # Enable Premium-aware scoring
xmaster config set style.voice "your style" # Writing voice for drafts
