x-writer
by ognjengtx-writer is a prompt skill for generating 3 high-engagement X posts from one idea, with proven formats and creator voice matching. Use x-writer for Social Media when you want fast, publishable, X-native copy with stronger hooks, tighter structure, and less guesswork than a generic prompt.
This skill scores 78/100, which means it is a solid listing candidate for directory users who want a structured X-post generator rather than a generic prompt. The repository shows a real workflow, clear trigger language, and substantial reference content, so users can judge install value with reasonable confidence, though it still benefits from tighter usage guidance.
- Strong triggerability: the description clearly says to use it for creating engaging X/Twitter posts, and the SKILL.md defines an explicit empty-arguments handshake.
- Good operational leverage: the skill requires reading three reference files with 49+ example posts, plus formats and voice profiles, which should reduce guesswork for the agent.
- Useful progressive disclosure: the workflow separates initialization from execution and gives concrete format/voice resources instead of leaving the model to improvise.
- No install command or setup instructions are provided, so users must infer how to activate it from the skill text alone.
- The repo focuses on X post generation only; it looks specialized rather than broadly reusable, so fit depends on whether users specifically need social post drafting.
Overview of x-writer skill
x-writer is a prompt skill for generating 3 high-engagement X posts from one idea, with format variation and creator voice matching built in. It is best for people who need fast, publishable social copy, not a generic brainstorming prompt: founders, marketers, ghostwriters, and operators who want stronger hooks, tighter structure, and posts that feel native to X.
What x-writer is for
The x-writer skill turns a rough topic into post-ready output using proven X formats and a reference-backed writing process. Its real job is to reduce guesswork around hook choice, post shape, and tone so you get multiple viable angles instead of one flat draft.
Why it is different
Unlike a one-off prompt, x-writer is opinionated about process: it requires reading three reference files first and uses them to anchor formats, examples, and voices. That makes it more useful when you care about consistency, repetition avoidance, and choosing between formats rather than just “writing something viral.”
Best fit and misfit cases
Use x-writer for Social Media when you already know the topic, offer, opinion, or announcement and want stronger X-native execution. It is a weaker fit if you need long-form strategy, multi-channel repurposing, or fully original brand messaging without a source idea.
How to Use x-writer skill
x-writer install and first run
Install with npx skills add ognjengt/founder-skills --skill x-writer. On first use, check whether your invocation passes $ARGUMENTS: if it is empty, the skill should load and wait; if it contains content, it should move directly into task execution.
What to read first
For x-writer usage, start with skills/x-writer/SKILL.md, then read all three required references before drafting: references/formats.md, references/posts.md, and references/voices.md. The first file defines structure, the second gives real post patterns, and the third helps you match tone without copying wording.
How to prompt it well
Give the skill a specific topic plus context that affects writing choices: audience, offer, desired voice, and what the post should achieve. Strong inputs look like: “Write 3 X posts about our waitlist launch for bootstrapped SaaS founders, in a confident, direct voice, with one contrarian angle, one story angle, and one utility angle.” Weak inputs like “write viral tweets” leave too many decisions unresolved.
Workflow that improves output
Use a simple sequence: topic → audience → proof or constraint → voice → desired outcome. If you already have a draft, tell x-writer whether to sharpen the hook, split it into formats, or rewrite it in a creator voice. When you review the result, compare the three outputs for format diversity and choose the one that best matches your goal, not just the most dramatic line.
x-writer skill FAQ
Is x-writer only for Twitter/X?
Yes, it is centered on X-native writing patterns. You can adapt the output elsewhere, but the skill is optimized for short, punchy, shareable posts rather than general social copy.
Do I need an exact prompt to use it?
No. x-writer works well with a rough idea, but better inputs produce better posts. If you only have a broad theme, add one concrete angle, one audience, and one reason people should care.
Is this better than a normal prompt?
Usually, yes, if you want repeatable structure and less trial-and-error. A normal prompt can produce decent copy, but x-writer gives you a clearer workflow, reference files, and a more reliable path to varied post formats.
When should I not use x-writer?
Do not use x-writer if you need a single long-thread strategy, platform-neutral copy, or deeply researched claims that depend on citations. It is strongest for concise, high-velocity post creation where tone and structure matter more than exhaustive explanation.
How to Improve x-writer skill
Give better source material
The biggest quality gain comes from giving x-writer sharper raw material: one point of view, one audience, one desired action. If the topic is broad, narrow it to a specific tension such as “why most founders post too broadly” or “how to frame a product launch without sounding promotional.”
Specify the post job
Tell the skill what success looks like. For x-writer, that might be attention, credibility, replies, clicks, or follows. The same topic should be written differently depending on whether you want a provocative one-liner, a practical list, or a creator-voice post.
Watch for common failure modes
The most common problems are generic hooks, repeated phrasing across the three posts, and voice matching that feels pasted on. To avoid that, ask for different formats, name a target voice from references/voices.md, and tell the skill what to avoid, such as jargon, hype, or salesy language.
Iterate after the first draft
Treat the first pass as a format exploration, then refine the winner. If one post is close, ask x-writer to make it more specific, more opinionated, or less verbose; if all three miss, improve the input before asking for a rewrite. The fastest path to better x-writer usage is clearer topic framing plus a tighter instruction on tone and outcome.
