Everything you need to remember about Claude, in one place.
The 5-Part System Prompt (for Projects)
Every strong Project system prompt covers:
- Role. "You are a {role} assistant at Empower."
- Context. Who you are, what the work looks like.
- Task priorities. 2–4 things Claude will most often do.
- Style. Tone, format, length.
- Constraints. What Claude should NOT do.

The 4 Levers That Fix Most Prompts
When output misses, check all four:
| Lever | Example |
|---|---|
| Role | "I'm an account manager at Empower." |
| Audience | "For a commercial client new to our service." |
| Purpose | "I need a one-page leave-behind after a site visit." |
| Format | "Three short paragraphs, plain language." |
8 Prompts That Earn Their Keep
1. Summarize in exactly 3 bullets. Plain language.
{PASTE}
2. Edit for clarity. Do not change meaning or tone.
{PASTE}
3. Compare {A} and {B}. Table of pros/cons, then your recommendation and the main reason.
4. What am I missing? I'm planning to {plan}. Risks, blind spots, or considerations?
5. Extract every action item. For each: owner, task, deadline. If unstated, "no deadline given."
{PASTE}
6. Play devil's advocate. 5 strongest arguments against doing this. Honest, not polite.
7. What do I need to know before {action}? Top 5–7 things, be specific.
8. Write a professional follow-up email after a meeting with {person}. We discussed {X}. Next step: {who does what when}. 3–4 sentences.

Mobile Shortcuts
- Voice — tap the mic. Dictate. Faster than thumb-typing by 3–4×.
- Photo — tap camera/library. Claude reads text, labels, diagrams.
- Share sheet — from any app (email, PDF, browser), tap Share → Claude. No copy-paste.
7 Pitfalls to Avoid
- One mistake ≠ unreliable. Review like you would an intern's work.
- Vague one-line prompts → vague output. Add role/audience/purpose/format.
- Re-explaining context every chat. Use a Project.
- Expecting Claude to see your email/files. It can't, unless you paste or connect.
- Expecting it to read your mind. Over-explain early on.
- Burying the ask in a long background paragraph. Lead with it.
- Sending Claude's draft without reading it. Never.

Habit Anchors
- Daily: every email longer than 3 sentences — draft with Claude first.
- Weekly: every meeting — paste rough notes into "Meeting Notes Cleaner" Project, get clean summary before the next calendar item.
- Monthly: 30-min review. What time did Claude save us? What didn't work?
Data & Privacy (the short version)
- Claude only sees what's in the chat window. No background access to your systems.
- Team and Enterprise content is not used to train models by default.
- Your workspace is isolated from other companies.
- Don't paste: SSNs, passwords, privileged legal docs, HIPAA data (unless Enterprise+HIPAA).

When Claude Feels Stuck
- "Too long" / "too short" / "more direct" — just say it in the next message.
- "You missed X" — Claude adjusts without restarting.
- Still wrong after 2 tries — your prompt is underspecified. Add one more sentence of context.
