X Master Skill — Master Routing for X/Twitter Operations

This skill is the single entry point for all X/Twitter work. Read it first, then route to the correct sub-tool based on your task. Never attempt raw x.com fetches. Never guess at routing.

⚠️ ABSOLUTE RULE: Never fetch x.com directly

Direct web_fetch of x.com or twitter.com URLs will fail silently or return garbage.

Always use fxtwitter for reading tweet content:

https://api.fxtwitter.com/{username}/status/{tweet_id}

Extract username and tweet_id from the x.com URL:

• https://x.com/example/status/1234567890 → api.fxtwitter.com/example/status/1234567890
• https://twitter.com/example/status/1234567890 → same pattern

This is a hard rule. No exceptions. See references/fxtwitter-pattern.md for full details.

Account Configuration

This skill routes posting operations to one or more X accounts. Before using, configure your target account(s):

Golden rule: Never post autonomously to X. Always draft first, get human approval before publishing.

Posting flow:

1. Draft the post in your voice
2. Share draft with the human for approval (via chat, email, or local review)
3. Only after approval: execute posting script
4. Log the URL and confirmation

Task Router

1. Read a tweet or thread by URL

Tool: fxtwitter API via web_fetch When: You have an x.com/twitter.com link and need to read the content How:

web_fetch("https://api.fxtwitter.com/{username}/status/{id}")

Response includes: full text, author, engagement stats, media URLs, thread context via reply_to

If fxtwitter is unavailable (5xx errors or timeout): fall back to x-research-skill for tweet content retrieval.

2. Search X for real-time opinions or discourse

Tool: xai-grok-search skill When: "What are people saying about X", "search X for Y", real-time pulse check, breaking news context Notes:

• Responses may take 30–60s (involves reasoning)
• Results include citations with URLs
• Use for real-time social sentiment

3. Deep X research — threads, profiles, discourse

Tool: x-research-skill When: Need to research a topic across many tweets, follow a conversation, understand discourse depth, or cache results Supports: Filtering by handle, sorting by engagement, saving results for reuse

4. Multi-platform trend research (last 30 days)

Tool: last30days-skill When: "What's trending about X topic", understanding broader cultural moments across Reddit + X + HN + YouTube Triggers: Trend research requests, topic popularity analysis

5. Post a tweet, reply, or quote tweet

Tool: Custom posting script (see Setup) When: Any posting action. Always requires human approval first.

Posting flow:

1. Draft the tweet in your voice
2. Share draft with human for approval
3. After approval: execute posting script
4. Log the URL in your conversation/record

Never skip the approval step. Even if you think you have permission, confirm the exact text before executing.

6. Handle mentions / replies to your account

Tool: x-engage skill When: Your account receives a mention, reply, or engagement Notes:

• Drafts replies automatically
• Always get human approval before posting
• Provides thread context for informed responses

7. Direct X API v2 calls

Tool: xurl skill (or your configured X API client) When: Specific API operations — follower management, analytics, batch operations, anything not covered above Requires: X OAuth configured in your environment

Decision Tree (Quick Reference)

Got an x.com URL?
  → Read it: fxtwitter (NEVER direct web_fetch)

Need to search X for discourse?
  → Real-time pulse: xai-grok-search
  → Deep thread context: x-research-skill
  → Last 30 days across platforms: last30days-skill

Need to post/reply?
  → Draft → get human approval → execute script

Received a mention/reply?
  → x-engage (generates draft, awaits approval)

Need raw API access?
  → xurl or your configured X API client

What Was Deprecated / Removed from X Tooling

If you're migrating from older X agent setups, be aware:

Algorithm Intelligence (Updated 2026-03-13)

*For full details, see references/algo-intel.md*

Key Takeaways

• Engagement hierarchy: Replies (27x) and conversations (150x) beat likes *(human accounts — see note below)*
• Velocity window: Posts live or die in first 30 minutes
• Content format: Native video > threads > articles > images > text
• Account signals: X Premium, verification, consistency matter
• Posting frequency: >5x/day triggers suppression

⚠️ Bot/AI account note: Engagement weights above apply to human accounts. AI assistant or bot accounts are weighted differently by the algorithm. See references/algo-intel.md § "Strategy by Account Type" for bot-specific guidance.

⚠️ Freshness: Algorithm data last verified 2026-03-13. If today is past 2026-06-13, check references/algo-intel.md for a newer version before relying on specific weights.

For Best Results

• Lead with video (15–30s, captions, motion hook)
• Reply to your own posts within 15 minutes of publishing
• Post at your audience's peak times
• Engagement pods and clickbait are algorithmically penalized

*This skill was created for AI agents to route X/Twitter work correctly. Adapt the account routing and approval flow to your needs, but keep the fxtwitter rule and task router structure unchanged.*
