What it does
X Virality is an agent skill from elophanto/EloPhanto. Concrete, algorithm-grounded guidance for writing X posts that the For You feed ranks high. Distilled from the public source of X's ranking system (github.com/xai-org/x-algorithm, May 2026 release). Use this BEFORE drafting any X post or reply. Pairs with the xstylepreflight tool (mechanical banned-phrase check) and the twitter-marketing skill (general practice).
Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with X (Twitter) and GitHub. The repository describes itself as: Source-available autonomous AI agent with a self-model that actually changes as it runs - ego, affect and identity grounded in real psychology (Higgins, PAD/OCC). Writes its own…
Example prompts
- “/x-virality”
Workflow steps
10 steps, taken from the step headings in SKILL.md.
- Open with a hook in the first 3-8 words
- Make people stop and read (dwell, not just glance)
- Provoke replies, don't beg for them
- Earn the profile click + follow
- Never write for not_dwelled
- Stay fresh — react fast or don't react
- Avoid the slop detector
- Be careful with images and video
- Don't stack posts on yourself
- Watch for spam-low-follower triggers
What it can do on your machine
Read from SKILL.md and the folder at commit 7bfc65d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
X Virality loads about 3.8k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 2,089 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,089 words (~3,842 tokens).
“The X For You feed is ranked by a Grok-based transformer (Phoenix) that predicts probabilities for 22 distinct user actions on every post and then computes a weighted sum. The weights are tuned at runtime via A/B testing — they…”
