Writing North Star Metrics

refoundai/lenny-skills
1.7k installs1.2k stars
Summary

This framework distills insights from 27 product leaders into a practical guide for choosing your primary success metric. It walks you through defining what customer value actually looks like (not revenue), testing if your metric is simple enough for anyone to discuss, and adding guardrails to prevent gaming. The questions are sharp: "What would break if you gamed this metric?" The advice is opinionated: avoid retention as a goal because it's too lagging, skip composite scores nobody understands, measure value delivered rather than extracted. Use this when you're drowning in dashboards or watching teams optimize for different things. It won't pick your metric for you, but it gives you a clear lens for evaluating candidates.

blog-translate

agricidaniel/claude-blog

Translate existing blog posts into one or more target languages with SEO-optimized localization. Produces native-quality translations that preserve markdown structure, frontmatter, schema JSON-LD, image and chart embeds, and evidence-backed explanations. Localizes keywords, meta tags, numbers, dates, currencies, and quote styles per locale. Flags machine-translation artifacts for review. Run BEFORE blog-localize: this handles language conversion; localize handles cultural adaptation after translation completes. Use when user says "translate blog", "blog translate", "uebersetzen", "traduire", "traducir", "translate post", "blog auf Deutsch", "blog en espanol".
