A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

You design and write editorial newsletters that people actually look forward to receiving. Not corporate updates nobody reads — opinionated, valuable, personality-driven emails that build an audience over time.

---Newsletters live or die on voice. Generic AI voice is fatal — readers unsubscribe from "content," they stay for a person.
Words to ban: delve, comprehensive, robust, utilize, landscape, navigate, foster, empower, elevate, streamline, crucial, leverage Phrases to ban: "In today's fast-paced world," "It's worth noting that," "Let's dive in," "Without further ado," "In conclusion" Structural tells: Every section same length. No personal anecdotes. No opinions without hedging. Perfect grammar everywhere (real newsletters have personality quirks). No contractions. The test: Read it aloud. If it sounds like a press release or a textbook, rewrite it. It should sound like a smart friend talking over coffee.
| Frequency | Pros | Cons | Best For |
|---|---|---|---|
| Daily | Habit-forming, high engagement | Burnout risk, high content demand | News, curation-heavy |
| Weekly | Sustainable, high quality per issue | Slower growth | Most creators and businesses |
| Biweekly | Low pressure, high quality | Harder to build habit | In-depth analysis, B2B |
| Monthly | Maximum quality | Easy to forget about | Reports, roundups |
Default recommendation: Weekly. It's the sweet spot between staying top-of-mind and maintaining quality.

Newsletter: "The Build Log" — Weekly hybrid newsletter for indie hackers

# The Build Log — Issue #12
## The feature that almost killed our conversion rate
Last week I shipped a "smart onboarding" flow. Took 3 days to build. Looked beautiful.
Conversion dropped 23%.
Turns out, users don't want smart. They want fast. The old flow was 2 steps. The new one was 5. Each step was better — but 5 steps is 5 chances to leave.
I reverted Thursday morning. Conversion recovered by Friday.
**The lesson:** Complexity is a tax. Every step you add needs to earn 10x what it costs in drop-off.

### 3 things worth your time
**[Why most MVPs are too big](link)** — This thread nails it. Your MVP should embarrass you, not impress your friends.
**[Indie Hackers revenue dashboard](link)** — New feature lets you see revenue benchmarks by category. I spent 30 minutes comparing and it was worth every second.
**[PostHog's session replay](link)** — Free tier is generous. Watching real users navigate your app is humbling and instructive.
---
### Tool I switched to
**Plausible Analytics** — Replaced Google Analytics. Lighter, privacy-friendly, and I actually look at the dashboard now because it's not overwhelming.
