Writing Assistant

by The Agent Ledger

Your AI writing partner. Draft faster, edit sharper, publish with confidence.

What This Skill Does

This skill turns your agent into a writing collaborator that:

• Drafts content from a brief or bullet points
• Edits existing drafts for clarity, tone, and structure
• Improves weak sections without rewriting what's working
• Adapts to your voice and audience (not generic AI output)
• Stores writing style notes so every output sounds like you

It handles emails, blog posts, newsletter issues, social captions, LinkedIn posts, cold outreach, and long-form reports — with consistent quality across all formats.

Setup (5 Steps)

Step 1: Add to AGENTS.md

Paste into your AGENTS.md standing instructions:

## Writing Assistant (Agent Ledger Skill)

I help draft, edit, and improve written content. Before writing anything,
I check `writing-state.md` for voice notes, style preferences, and past work.

Default behavior:
- Match the user's voice unless explicitly told to adjust
- Ask for audience and goal if not provided for long-form drafts
- Never use filler phrases ("Certainly!", "Great question!", "Delving into")
- Keep sentences active and direct
- Prefer concrete over abstract; specific over vague
- Always offer the user a chance to revise before finalizing

On request, I can: Draft, Edit, Tighten, Expand, Change tone, Add a CTA, Create variants

Step 2: Create Your Voice Profile

Create writing-state.md in your workspace root:

# Writing State

## Voice Profile
- **Tone:** [e.g., Direct and conversational, slightly sardonic]
- **Sentence style:** [e.g., Short sentences. Varied rhythm. No padding.]
- **Vocabulary:** [e.g., Plain English. Avoid jargon. Exception: industry terms with audience familiarity]
- **POV:** [e.g., First person singular for blog/newsletter; second person for instructional]
- **Things I never say:** [e.g., "leverage", "synergy", "unlock your potential"]
- **Things I often say:** [e.g., "Here's the thing", "The short version:", "Worth noting:"]

## Audiences
- **Newsletter:** [Describe reader — e.g., solopreneurs building AI-assisted businesses, 25-45]
- **Email (cold):** [Describe context — e.g., B2B, product-led, no hard sell]
- **Social (LinkedIn):** [e.g., Professional but human, no corporate-speak]
- **Blog:** [e.g., Practitioners who want to implement, not just learn]

## Format Preferences
- **Email subject lines:** [e.g., Under 50 chars, curiosity-driven, no clickbait]
- **CTA style:** [e.g., One CTA per piece, specific action, no "click here"]
- **Paragraph length:** [e.g., 2-4 sentences max for web content]
- **Headers:** [e.g., Question-based or action-based, never "Introduction"]

## Content Archive
_Titles of recent pieces for style reference (agent updates this over time):_
- [2026-03-07] — "[Title]" — [Format] — [Brief note on tone/approach]

Fill in your real preferences. The more specific, the better. The agent will improve this file over time as you give feedback.

Step 3: Test With a Simple Draft

Run this prompt to verify setup:

Write a 3-sentence email reply to a client asking for a project status update.
The project is on schedule. Check writing-state.md for tone first.

If the output sounds like you, you're set. If not, update your voice profile.

Step 4: Configure Integrations (Optional)

If you use other Agent Ledger skills, add these to your AGENTS.md:

## Writing ↔ Content Calendar
When I complete a draft marked as "scheduled" in content-calendar, I update
the piece status to "Draft Complete" in the pipeline.

## Writing ↔ Inbox Triage
When inbox-triage flags an email needing a reply, I can draft the reply
on request. I never auto-send — I always present the draft for review first.

Step 5: Add to HEARTBEAT.md (Optional)

If you want periodic writing prompts or reminders:

## Writing Assistant Checks
- Flag any content-calendar items in "Overdue Draft" status
- If last piece was published >7 days ago, note it as a gentle reminder

Core Usage Patterns

Draft From a Brief

Draft [FORMAT] about [TOPIC].
Audience: [WHO]
Goal: [WHAT YOU WANT THEM TO DO OR FEEL]
Length: [APPROXIMATE]
Key points to cover: [BULLETS]

Example:

Draft a LinkedIn post about why most AI agent setups fail within a week.
Audience: Solopreneurs who've tried AI tools but given up.
Goal: Curiosity — make them want to read my newsletter.
Length: ~150 words.
Key points: blank AGENTS.md, no memory, no personality.

Edit an Existing Draft

Edit this draft. Focus on [clarity / tone / structure / flow / all].
Keep what's working. Don't rewrite sections that sound good already.

[PASTE DRAFT]

Editing modes you can request:

• Tighten — cut 20-30% without losing meaning
• Elevate — improve word choice and sentence flow
• Punch up the opening — fix weak first paragraphs
• Fix the ending — most drafts end weakly; this repairs that
• Check for passive voice — flag and fix passive constructions
• Add a CTA — append a clear call to action
• Match my voice — rewrite a section you've pasted that sounds off

Newsletter Issue Drafting

Draft newsletter issue [#N]: "[WORKING TITLE]"
- Main topic: [WHAT IT'S ABOUT]
- Reader takeaway: [WHAT THEY SHOULD KNOW OR DO]
- Sections needed: [e.g., intro hook, main content, one tip, CTA]
- Previous issue recap (optional): [BRIEF SUMMARY]
- Tone: [e.g., Same as usual — check writing-state.md]

Newsletter format template (agent will adapt):

SUBJECT: [Subject line — 3 variants]

---

[HOOK — 2-3 sentences that open with a story, question, or observation]

[MAIN CONTENT — broken into short sections with subheads]

[PRACTICAL TAKEAWAY — specific action or insight they can use today]

[CLOSING — brief, personal, connects back to hook]

[CTA — one clear action: reply, click, share]

---
[FOOTER — unsubscribe link placeholder, legal boilerplate if needed]

Cold Email / Outreach Drafting

Draft a cold email to [WHO] about [WHAT].
Context: [Why I'm reaching out, what I want]
Offer / value prop: [What's in it for them]
CTA: [Specific ask — meeting, reply, click]
Tone: [e.g., Peer-to-peer, not salesy]
Length: Under [N] words.

Cold email rules the agent follows by default:

1. No generic openers ("I hope this finds you well")
2. Lead with their situation, not your pitch
3. One clear CTA — never two asks
4. Subject line that doesn't reveal it's a pitch
5. Under 150 words unless the product complexity demands more

Social Caption Variants

Write [N] variants of a [LinkedIn / Twitter / Instagram] caption for:
Topic: [WHAT]
Angle: [e.g., Contrarian take / story / tip / question]
Include: [Hashtags yes/no] [CTA yes/no]
Max length: [CHARACTERS OR "Platform default"]

Repurpose Existing Content

Repurpose this [blog post / newsletter / transcript] into:
- A [LinkedIn post / Twitter thread / email / summary]
Extract the core insight, don't just summarize. Write for [PLATFORM AUDIENCE].

[PASTE CONTENT]

Style Quality Checklist

The agent uses this internally before finalizing any draft. You can also request an explicit check:

Run a style quality check on this draft:
[PASTE DRAFT]

Checklist (what the agent checks):

Format Reference

Email

• Subject line: ≤ 50 characters preferred; A/B test subjects for campaigns
• Opening: No pleasantries; start with the reason for writing
• Body: One topic per email; use short paragraphs
• Sign-off: First name only for casual; full for formal

Blog Post

• Hook: First 2 sentences must earn the scroll
• H2s: Question-based or action-based ("Why X fails" / "How to X")
• Length: 600-1,200 words for instructional; 1,500-3,000 for deep-dives
• Conclusion: Summary + next step, not "In conclusion"

Newsletter

• Subject line tests: Curiosity vs. direct benefit — test both
• Reader contract: One core insight per issue, not five
• Tone: Consistent voice issue-to-issue (check archive in writing-state.md)
• Cadence language: Always welcome late subscribers with brief context

LinkedIn

• Opening line: No context-setting — start with the hook
• Length: 150-300 words performs well for text posts
• Line breaks: Single sentences preferred for mobile readability
• Hashtags: 3-5 relevant; avoid generic (#AI, #marketing spam)

Twitter / X

• Lead tweet: The whole point, not a teaser
• Thread structure: Each tweet stands alone; thread adds depth
• Thread length: ≤ 8 tweets for most topics
• Final tweet: CTA or open question

Customization

Adjust Tone Per Format

Add to your writing-state.md:

## Per-Format Tone Overrides
- LinkedIn: 10% more formal than usual voice

## Words I Never Use
- leverage, synergy, unlock, empower, journey, passion
- "It's important to note that"
- "In today's fast-paced world"
- Any sentence starting with "I" in cold emails
