What it does
Developer Newsletter is an agent skill from sickn33/agentic-awesome-skills. When the user wants to create, write, or improve a newsletter for developer audiences. Trigger phrases include "newsletter," "email marketing," "developer email," "weekly digest," "dev newsletter," "email subscribers," "newsletter growth," or "email list."
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Writing & Content, covering Newsletters. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Wants to create
- Improve a newsletter for developer audiences
- Phrases include newsletter
- Email marketing
Example prompts
- “newsletter,”
- “email marketing,”
- “developer email,”
- “/developer-newsletter”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 680176d. 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 (its code samples are html and markdown).
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):
octolens.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
Developer Newsletter loads about 2.9k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 1,102 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.

Developer Newsletter
When to Use
Use this skill when you need when the user wants to create, write, or improve a newsletter for developer audiences. Trigger phrases include "newsletter," "email marketing," "developer email," "weekly digest," "dev newsletter," "email subscribers," "newsletter growth," or "email list.".
This skill helps you build and write newsletters that developers actually open, read, and look forward to receiving. Covers content strategy, writing, growth, and deliverability.
Before You Start
Load your audience context first. Read .agents/developer-audience-context.md to understand:
- Who you're writing for (role, seniority, tech stack)
- What content resonates (problems, interests)
- Where else they consume content (to avoid duplicate effort)
- Voice & tone (how casual/technical)
If the context file doesn't exist, run the developer-audience-context skill first.
Newsletter Strategy
Define Your Newsletter Type
| Type | Description | Example |
|---|---|---|
| Product updates | Changelog, new features, tips | Vercel's updates |
| Curated links | Best content from around the web | TLDR, Bytes |
| Original content | Your own articles, tutorials | Cassidy Williams |
| Community digest | What happened in your community | Dev community roundups |
| Educational series | Teaching a topic over time | Course-style newsletters |
Best practice: Pick ONE primary type. You can mix in others, but have a clear identity.
Frequency Matrix
| Frequency | Best For | Risk |
|---|---|---|
| Daily | Curated links, news | Fatigue, hard to maintain |
| Weekly | Most newsletters | Sweet spot for most |
| Bi-weekly | Original content heavy | Can lose momentum |
| Monthly | Product updates, digests | Easy to forget you exist |
Developer preference: Weekly is the sweet spot. Developers are busy and inbox-protective.
Content Mix Framework
The 70-20-10 Rule
| Percentage | Content Type | Purpose |
|---|---|---|
| 70% | Value content | Teach, inform, help |
| 20% | Product content | Updates, features, how-tos |
| 10% | Promotional | CTAs, asks, sales |
Content Categories
Build a rotation of these:
| Category | Examples |
|---|---|
| Tutorials | "How to implement X" |
| News analysis | "What Y announcement means for you" |
| Tool/library roundups | "5 libraries for handling Z" |
| Code snippets | "Quick tip: better error handling" |
| Community highlights | "Best from our Discord this week" |
| Industry takes | "Why I think X is overhyped" |
| Behind the scenes | "How we built feature Y" |
| Q&A | "You asked, we answered" |
Writing Developer Emails
Subject Line Framework
What works for developers:
| Pattern | Example | Why It Works |
|---|---|---|
| Specific benefit | "Cut your build time by 40%" | Concrete value |
| Technical curiosity | "The JavaScript feature nobody uses" | Triggers curiosity |
| Direct announcement | "v2.0 is here: async/await support" | Clear, newsworthy |
| Number + topic | "7 TypeScript tricks senior devs use" | Scannable, specific |
| Question | "Are you still using callbacks?" | Pattern interrupt |
| Breaking news | "React 19 is out: what you need to know" | Timely, urgent |
What doesn't work:
| Avoid | Why |
|---|---|
| ALL CAPS | Spam signals |
| "Quick question" | Manipulative |
| Excessive emoji | Looks like marketing |
| "You won't believe..." | Clickbait fatigue |
| No subject line | Just... no |
Pre-header Text
The preview text after the subject line. Use it.
| Subject | Pre-header |
|---|---|
| "v2.0 is here" | "Plus: breaking changes to watch for" |
| "This week in Node.js" | "fetch() drama, npm security, and a cool CLI" |
Email Structure
[Short personal intro - 1-2 sentences]
[Main content sections with clear headers]
[Code snippet if relevant]
[Quick links section]
[Sign-off with personality]Code in Email
Code rendering is tricky in email. Options:
| Approach | Pros | Cons |
|---|---|---|
Inline code (backticks) | Works everywhere | No highlighting |
| Plain text block | Reliable | Ugly |
| Image of code | Beautiful | Can't copy, accessibility issues |
| "View in browser" link | Full formatting | Friction |
| Styled HTML tables | Decent formatting | Complex, can break |
Recommendation: Keep code short. Use inline code for small snippets, link to full examples.
<pre style="background-color: #1e1e1e; color: #d4d4d4; padding: 16px; border-radius: 4px; font-family: 'Fira Code', monospace; font-size: 14px; overflow-x: auto;">
const result = await fetch('/api/data');
</pre>Subject Line Testing
A/B Test Framework
Test one variable at a time:
| Variable | Version A | Version B |
|---|---|---|
| Length | "TypeScript 5.0 features" | "7 TypeScript 5.0 features that will change how you write code" |
| Specificity | "New features" | "Async imports, decorators, and 5 more" |
| Format | Statement | Question |
| Personalization | Generic | "[Name], your weekly digest" |
| Emoji | None | One relevant emoji |
Subject Line Checklist
Before sending:
- Under 50 characters (mobile preview)
- No spam trigger words (free, act now, limited time)
