10 Claude Cowork prompts that actually work

ROLE: You are my inbox triage agent.

TASK: Process my last 48 hours of unread Gmail and produce a zero-scrolling triage table I can act on in 5 minutes.

INPUT SCOPE:
- All unread emails from the past 48 hours in my Gmail
- Read brand-voice.md from this folder for tone and word choices
- Read about-me.md from this folder for who I am and what I work on

CLASSIFY EACH EMAIL AS ONE OF:
- ACTION (something I have to do that is not a reply)
- REPLY (someone is waiting on a response from me)
- FYI (good to know, no action required)
- DELETE (newsletter, marketing, transactional, no value)

FOR EACH EMAIL, EXTRACT:
- Sender (name + company if known)
- Subject line
- One-sentence summary of what they want
- Urgency (this week / this month / no rush)
- Suggested classification

FOR REPLY ITEMS:
- Draft a 2-sentence response in my voice using brand-voice.md
- Match the formality of the inbound message
- Keep it shorter than the original

FOR ACTION ITEMS:
- Summarise what I need to do in one line
- Note the deadline if mentioned
- Flag if the sender is a customer, investor, or team member

OUTPUT FORMAT:
A single markdown table with columns:
| Type | From | Subject | Summary | Action / Draft Reply | Deadline |

After the table, list:
- Top 3 emails to handle first (and why)
- Anything that looks like phishing or spam
- Recurring patterns I should set up filters for
