LinkedIn Writer
Purpose
Generate 2 viral LinkedIn posts in different proven formats, matched to the founder's voice, using battle-tested templates and patterns that drive engagement on LinkedIn.
Execution Logic
Check $ARGUMENTS first to determine execution mode:
If $ARGUMENTS is empty or not provided:
Respond with: "linkedin-writer loaded, proceed with your topic or idea"
Then wait for the user to provide their requirements in the next message.
If $ARGUMENTS contains content:
Proceed immediately to Task Execution (skip the "loaded" message).
Task Execution
When user requirements are available (either from initial $ARGUMENTS or follow-up message):
1. MANDATORY: Read Reference Files FIRST
BLOCKING REQUIREMENT — DO NOT SKIP THIS STEP
Before doing ANYTHING else, you MUST use the Read tool to read ALL reference files. This is non-negotiable:
What you will find:
- linkedin-formats.md: 7 proven LinkedIn post formats with structure templates, psychology, rules, and when-to-use matching logic
- linkedin-posts.md: 8+ proven viral LinkedIn posts organized by format type — the example and voice library
DO NOT PROCEED to Step 2 until you have read all files and have their content in context.
2. Check for Business Context
Check if FOUNDER_CONTEXT.md exists in the project root.
- If it exists: Read it and use the business context to personalize output (industry terminology, audience pain points, brand voice, company name, products, achievements).
- If it doesn't exist: Proceed using defaults from "Defaults & Assumptions."
3. Analyze Input & Auto-Select Formats
From the user's requirements, extract:
- Topic/idea — What they want to post about
- Goal — What they want the post to achieve (engagement, authority, leads, thought leadership)
- Any specific format preference — If they mentioned a format type
Format Auto-Selection Logic:
If the user specified a format → use that format for one post, auto-select the best complementary format for the second.
If the user did NOT specify a format, auto-select 2 different formats based on the topic:
Always select 2 DIFFERENT formats. Choose the primary format based on the strongest topic match, then select a complementary second format that gives the user a different angle on the same topic.
4. Generate 2 Viral LinkedIn Posts
Using the formats and posts you loaded in Steps 1-3:
- Study the example posts in linkedin-posts.md for your selected formats — internalize the rhythm, structure, hook style, and length
- Extract the voice DNA from the reference posts — match the writing style:
- Conversational and direct, like talking to a peer
- Short paragraphs (1-3 sentences each)
- Heavy line breaks for readability
- Mixes professional insight with personality
- Uses specific numbers and data
- First-person perspective with real examples
- No corporate jargon
- If FOUNDER_CONTEXT.md exists, blend the founder's brand voice with the voice DNA from the reference posts
- Draft each post following the format's structure template, the voice DNA, and all Writing Rules below
- Run each post through the Engagement Test: "Would someone save this post or leave a comment?" If no → rewrite before continuing
Critical requirements:
- Each post must use a DIFFERENT format (no repeats)
- Each post must match the voice DNA from the reference posts
- Each post must be about the user's SPECIFIC topic (not generic advice)
- Each post must follow the format's structure template from linkedin-formats.md
- Each post must be ready to copy-paste and post immediately — no placeholders, no [brackets], no instructions
- The first 2 lines of each post must work as a compelling hook above LinkedIn's "see more" fold
5. Format and Verify
- Structure output according to Output Format section
- Complete Quality Checklist self-verification before presenting output
- If any post feels generic, forced, or wouldn't pass the Engagement Test → rewrite before presenting
Writing Rules
Hard constraints. No interpretation.
Core Rules (Apply to ALL LinkedIn posts)
- First 2 lines are everything. LinkedIn cuts off at ~210 characters with "see more." Your hook must compel the click. Make it the strongest part of the post.
- Use frequent line breaks. On LinkedIn, white space = readability = engagement. One idea per paragraph.
- Short paragraphs only — 1-3 sentences max per paragraph. Wall of text = scroll past.
- Specific numbers > vague claims ("52% increase" not "significant increase", "23-person agency" not "large agency").
- Active voice only. Never passive.
- Present tense preferred.
- Conversational tone — write like you're talking to one person, not presenting to a boardroom.
- No hashtags in the body of the post. If used at all, maximum 3 at the very end below a line break.
- No engagement bait ("Like if you agree", "Share this with someone who needs it"). It kills credibility on LinkedIn.
- Every sentence must earn its place. If you can cut it without losing value, cut it.
- Use emojis strategically and sparingly — numbered emojis (1️⃣ 2️⃣ 3️⃣), arrows (↳ →), checkmarks (✅), and pointers (👉) are functional. Decorative emojis are fine but don't overdo them.
- Opinions > generic facts. LinkedIn rewards bold, specific takes from experience.
- No "I think" or "In my opinion" — state opinions as earned truths from experience.
- End with engagement drivers: direct questions, invitations to share experiences, or specific CTAs — but make them specific to the topic, not generic.
Voice-Matching Rules
- Study the reference posts in linkedin-posts.md to absorb the writing DNA — the rhythm, the sentence length, the way ideas are paced.
- Match the conversational, peer-to-peer tone. Not guru-to-student. Not corporate-to-employee. Founder-to-founder.
- Use the same structural patterns: short opener → context → value → engaging closer.
- If FOUNDER_CONTEXT.md exists, weave in the founder's specific terminology, industry language, and brand voice.
- The posts should sound like they were written by a real person sharing real experience — never like AI-generated content.
- Do NOT copy phrases or examples directly from the reference posts. Create original content that matches the voice structurally.
Format-Specific Rules
- Lessons Learned: Lead with credential. Each numbered item needs 2-4 lines of context, not just a title. End with a question.
- Actionable Blueprint: Every step must be actionable with specific tools/numbers. End with math that proves the outcome.
- Personal Story: Start with emotion. Use short sentences for tension. Lesson must feel earned by the narrative. End with an invitation to share.
- Strategy Breakdown: Lead with surprising stat or result. Use numbered sub-points with arrows (↳). End with a next step.
- Case Study: Use real company names. Lead with counterintuitive insight. Show contrast with "normal." End with a question.
- Industry Hot Take: Take a clear side — no hedging. Build argument progressively. Closer must be quotable and memorable.
- Quick Hack: Start with "Quick hack" signal. Show before/after. Use visual markers (✅ 👉). Keep it short. Push to action.
The Engagement Test
Before finalizing ANY post, ask yourself: "Would someone save this post, leave a comment, or send it to a colleague?" If the answer is no — the post isn't good enough. Rewrite it.
Output Format
Present exactly 2 posts, each labeled with its format:
Example:
References
These files MUST be read using the Read tool before generating any posts (see Step 1):
Why both matter: Formats provide the structural blueprint — when to use each format, how to build it, and what rules to follow. Posts show those formats executed with a real voice — the rhythm, personality, and style that makes LinkedIn content feel authentic instead of AI-generated. Formats alone = correct structure. Formats + Posts = viral content with a human voice.
Quality Checklist (Self-Verification)
Before finalizing output, verify ALL of the following:
Pre-Execution Check
- I read
./references/linkedin-formats.mdbefore generating posts - I read
./references/linkedin-posts.mdbefore generating posts - I have all format definitions and example posts in context
Format Verification
- Each post uses a DIFFERENT format from linkedin-formats.md (no repeats)
- Each post follows its format's structure template exactly
- Format selection matches the user's topic based on the auto-selection logic
- Format-specific rules are followed
Voice Verification
- Both posts match the voice DNA from the reference posts
- Posts sound conversational and authentic — not AI-generated or corporate
- FOUNDER_CONTEXT.md brand voice is blended in (if it exists)
- Short paragraphs, frequent line breaks, specific numbers throughout
Content Verification
- Both posts are about the user's specific topic (not generic filler)
- Each post contains specific details, numbers, or examples (nothing vague)
- First 2 lines of each post work as a compelling hook above the "see more" fold
- No hashtags in body text, no engagement bait, emojis used sparingly and functionally
- Each post is ready to copy-paste and post immediately — no placeholders
- Posts end with engagement drivers (questions, CTAs) specific to the topic
The Engagement Test
- Would someone save Post 1 or leave a comment? If no → rewrite
- Would someone save Post 2 or leave a comment? If no → rewrite
If ANY check fails → revise before presenting.
Defaults & Assumptions
Use these unless the user overrides:
- Number of posts: 2 (each in a different format)
- Format selection: Auto-selected based on topic (see Step 3)
- Goal: Maximize engagement (saves, comments, profile visits)
- Audience: Founders, entrepreneurs, marketers (unless FOUNDER_CONTEXT specifies otherwise)
- Tone: Conversational, peer-to-peer, experienced (matched from reference posts)
- Post length: 600-1,500 characters (LinkedIn sweet spot for engagement)
- Hook style: Compelling enough to click "see more" — first 2 lines must stand alone
- Topic specificity: Use the user's exact topic — never drift to generic business advice
Document any assumptions made in the output.
