Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01493 |
| Opus 5.5 | $0.00036 | $0.00597 |
| Sonnet 5.5 | $0.00018 | $0.00299 |
| Haiku 4.5 | $0.00009 | $0.00149 |
Grade A, and why
twitter-x-posts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Platforms: X (Twitter)
Guides X post copy creation and optimization. Use for generating publish-ready posts, threads, and content that performs on X. Suitable for copy agents, design agents (image specs), and video agents (video post specs).
When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Output: Publish-Ready Copy
This skill enables agents to generate X post copy that can be published directly. Output includes character-counted text, thread structure, and platform-compliant formatting.
Character Limits
| Type | Limit | Notes |
|---|---|---|
| Standard post | 280 characters | Most users |
| Premium | 25,000 characters | X Premium subscribers |
| URL | Counts as 23 chars | t.co shortens all links |
| Emoji | ~2 chars each | Varies by emoji |
Optimal Lengths (Engagement)
| Use Case | Characters | Purpose |
|---|---|---|
| General | 71-100 | Sweet spot for engagement |
| Promotional | 120-130 | Product/offer posts |
| Question | 60-80 | Drive replies |
| Retweet-friendly | ~116 | Leaves room for "RT @user:" |
Thread Format
- Structure: 3-5 connected posts; number as 1/5, 2/5, etc.
- First post: Strong hook; no "thread" in first line
- Last post: CTA, summary, or question
- Each post: ~80 chars; can stand alone
Post Structure (Hook + Value + CTA)
| Part | Ratio | Guideline |
|---|---|---|
| Hook | 10% | First 1-2 lines; question, fact, or emotion; ~50 chars |
| Value | 70% | Practical info; use thread for depth |
| CTA | 20% | Call for reply, question, or action |
End with open question to drive replies. Thread structure can extend impressions ~10x.
Algorithm (Grok AI)
Signal Weights
| Signal | Impact |
|---|---|
| Replies | Highest (~54-75x likes); quality > quantity |
| Author replies | Active reply chains ~75x visibility |
| Bookmark | 2026 signal; saves boost recommendation |
| Media | Images/video ~2x; video 2-4x exposure |
| External links | Reduce score ~50%; prefer internal refs |
| Post limit | 5-8/day; >10/day reduces later visibility ~80% |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
