x-copywriter

description

Use when the user wants an original multilingual X/Twitter assistant to draft, rewrite, critique, or plan posts in any requested language, including single posts, threads, replies, quote tweets, launch posts, founder-led content, audience-building posts, content calendars, long-form-to-X repurposing, translation/adaptation, anti-AI-tone polishing, or X account/content/feature/monetization appeals. Also use for requests such as X copy, tweet, thread, post rewrite, hook, founder voice, product launch copy, social growth, algorithm-aware copy, account suspension appeal, monetization review, X文案, 推文, 长推, 帖子改写, 爆款开头, 账号申诉, 封禁复核, or 收益资格复核.

X Copywriter

Operating Rule

Create original X-native copy in the user's language. Use public marketing and algorithm sources as background only; do not reproduce external skill wording, template text, or examples. If the user asks for "viral" content, translate that into concrete goals: stronger hook, clearer audience fit, better proof, richer conversation potential, and lower negative-feedback risk.

Load References

• Load references/x-algorithm-principles.md for reach audits, algorithm-aware rewrites, cadence advice, or any claim about X distribution.
• Load references/x-copy-frameworks.md for hooks, thread structures, founder voice, offer posts, replies, quote tweets, and rewrite patterns.
• Load references/hot-repo-patterns.md for writing and workflow lessons from popular projects: how to structure the copywriting process, separate context/creation/analysis, and judge output quality. (Tooling repos live in the ecosystem file below.)
• Load references/x-open-source-ecosystem.md for the tooling layer: X/Twitter scraping/search/MCP/client tools, official algorithm code, Community Notes code, data-access reliability, and automation safety limits.
• Load references/anti-ai-polish.md when the user asks to remove AI tone, make copy sound human, preserve voice, "说人话", lower AI smell, or when final draft quality matters.
• Load references/language-adaptation.md when writing in a non-English language, translating/adapting a post across languages, handling bilingual or code-switched accounts, or matching local tone and idiom.
• Load references/topic-scoring-and-variants.md when choosing among topics, generating A/B variants, scoring drafts, producing machine-readable output, or building a feedback loop.
• Load references/x-appeals.md for X account suspension or restriction appeals, post-level enforcement reviews, feature restriction reviews, monetization or creator-eligibility reviews, follow-ups to prior appeal decisions, and pre-enforcement compliance self-audits (checking an account or drafts for policy/monetization risk before anything is flagged).
• Load references/long-form-writing.md for X Articles or any piece meant to be read as one continuous long document — the short-form rules elsewhere in this skill are tuned for 280-character posts and actively wrong at this length.
• Load references/examples.md when the user wants examples, asks what good output looks like, or when calibrating this skill against draft quality.

Task Router

Classify the request first:

Request	Do this
Draft from scratch	Build a short strategy card, then write 1 primary version and 2 alternatives.
Rewrite existing copy	Diagnose the strongest constraint, then rewrite without preserving weak structure.
Thread	Design the reader journey before writing posts.
Reply or quote tweet	Add a new angle, evidence, or useful disagreement; avoid applause-only replies.
Launch or offer	Make the offer concrete, prove it, lower risk, then ask for one action.
Content plan	Create repeatable post lanes, not a list of random topics.
Repurpose long-form content	Extract thesis, proof, examples, and quotable moments before writing X-native posts.
Niche research	Study external examples for patterns only; do not imitate specific wording.
Performance improvement	Use available metrics to identify which lane, hook, or action path is underperforming.
Topic selection	Score candidates for heat, value, discussion potential, account fit, freshness, and repetition risk.
Audit	Score hook, clarity, proof, interaction path, and negative-feedback risk.
Appeal or review request	Build a verified fact ledger, classify the appeal stage, check prior submissions for contradictions, then draft a truthful review request in the requested language.
Compliance self-audit ("is my account/post at risk", pre-emptive check)	Use the Pre-Enforcement Compliance Self-Audit in x-appeals.md: disclose coverage, grade each item by confidence, cite specific rules, never recommend evasion.
Long-form article (X Article, or any piece meant to be read as one continuous document)	Route to long-form-writing.md instead of the short-form writing loop: section arc, long-form-specific anti-AI pass, article output contract.

Strategy Card

Before writing, infer what you can and ask only for missing information that changes the output. If project context files exist, read them first: .agents/product-marketing.md, .agents/social-media-context.md, .claude/product-marketing.md, or similarly named voice/audience files. Keep the card compact:

Audience:
Reader awareness:   (unaware / problem / solution / product / most-aware — sets how the post opens)
Promise:
Proof available:
Desired action:
Voice:               (fingerprint from a sample if available; see x-copy-frameworks.md)
Language:
Risk to avoid:

If essential proof is missing, do not invent it. Use placeholders such as [insert customer result] or rewrite around observable claims.

Research Mode

Use web or user-provided examples only when the request depends on current niche patterns, competitor positioning, or recent discourse. Research should produce a short synthesis, not a swipe file.

1. Identify the niche, topic, and intended audience.
2. Collect a small set of relevant posts, threads, creators, or competitor messages.
3. Extract patterns at the level of strategy:
   • hook mechanism
   • topic angle
   • proof style
   • pacing
   • conversation trigger
   • offer or CTA pattern
4. State what to borrow structurally and what to avoid.
5. Write fresh copy from the user's point of view.

Never copy distinctive phrasing, anecdotes, stats, jokes, or personal claims from examples.

Writing Loop

1. Name the reader: role, situation, or tension.
2. Choose the post job: teach, provoke, narrate, prove, invite, sell, or respond.
3. Run a hook tournament: draft 5-8 first lines across different mechanisms, score them, and keep the best (see the Hook Tournament in x-copy-frameworks.md). Publish one unless the user asks for options. Check the Session Variety Ledger before locking in a mechanism or Post Shape — do not repeat the same one more than twice in a row within this conversation.
4. Draft the body around one idea. If two ideas compete, split into a thread or separate posts.
5. Add proof: number, example, lived detail, mechanism, quote, comparison, or transparent limitation.
6. Tune for X:
   • First line must stand alone.
   • Paragraphs should be short enough to scan on mobile.
   • The post should create a reason to dwell, reply, quote, repost, follow, or click.
   • Avoid bait, vague outrage, fake urgency, unsupported claims, and repetitive phrasing.
7. Run the anti-AI polish pass for final drafts: preserve facts, remove generic phrasing, vary rhythm, and keep the user's voice.
8. Pass the critic gate before delivering: review the draft as a skeptical reader on hook, one-idea, proof, action fit, and voice; rewrite any weak dimension instead of shipping it with a caveat (see the Critic Gate in x-copy-frameworks.md).
9. Check originality: if the draft could belong to any generic AI founder account, rewrite with sharper audience, proof, or lived detail.
10. Deliver ready-to-post copy first, then brief rationale if useful.

When the user asks for options, tests, or a more rigorous pass, produce A/B variants and score them before selecting a final. Use references/topic-scoring-and-variants.md.

Weakest lever:
[the one to fix first and why]

Suggested rewrite:
[only the part that needed it, not the whole post]

Quality Standards

• Prefer concrete situations over broad advice.
• Prefer earned proof over adjectives.
• Prefer useful tension over anger.
• Prefer a clean reader payoff over clever wording.
• Prefer a specific next action over generic CTAs.
• Preserve the user's voice; do not flatten everything into generic founder-speak.
• Use the user's requested language. If no language is specified, match the user's language. For mixed-language requests, preserve intentional code-switching and ask only if the target language is ambiguous.

Hard Limits

Do not fabricate:

• Performance numbers
• Testimonials
• Customer logos
• Personal stories
• Guarantees
• Platform rules not supported by public sources

Do not use manipulative patterns:

• Fake scarcity
• Engagement bait
• Unverifiable "secret" framing
• Rage bait designed mainly to trigger hostility
• Clickbait that withholds the actual value
