Build a custom Claude skill from scratch

Great — a skill that auto-generates weekly LinkedIn posts in your founder voice. Before I draft the definition, let me scope it so it fires correctly and produces what you actually want.

**1. Trigger — when should this fire?**
Should it activate only when you explicitly say something like "draft this week's LinkedIn post," or also when you paste a raw idea/observation and ask for a post? I'd lean toward an explicit trigger phrase so it doesn't hijack unrelated writing tasks.

**2. Required vs. optional inputs**
- *Required:* the core idea or story for the week.
- *Optional:* a target outcome (followers / comments / DMs), a link to include, a specific lesson to emphasize.
Anything else you'd want it to always ask for?

**3. Output format**
150–220 words, hook-first, no emojis, one CTA question at the end? And should it always return 3 hook variants, or just one finished post?

**4. Examples of great output**
Can you paste 2–3 of your best-performing past posts? That anchors the voice far better than adjectives.

**5. Examples to avoid**
Anything you hate — corporate speak, "thread" announcements, humblebrags, em-dash overuse?

Once you answer these, I'll draft the full skill definition — front-matter, trigger rules, and the prompt body — ready for you to drop into your `.claude/skills` folder and test.
