Step 5: Pro Tips and Best Practices

Tip 1: Be Specific in Your Instructions

Bad Example:

"Fix my files"

Good Example:

"Review all PDF files in the 'contracts' folder, identify any that are missing signatures on the last page, and create a list with file names and page numbers where signatures are needed."

Tip 2: Use Progressive Tasks

Break complex work into steps:

1. First: "Analyze the files in this folder and tell me what you find"
2. Then: "Based on your analysis, suggest an organization scheme"
3. Finally: "Implement the organization scheme we discussed"

Tip 3: Leverage the Plan-Review-Execute Cycle

You: "Organize my project files"
Claude: [Shows detailed plan]
You: "Actually, keep the 'archive' folder separate"
Claude: [Updates plan]
You: "Proceed"
Claude: [Executes]

Tip 4: Create Reusable Instructions

Save common workflows as text files that you can copy-paste:

## Weekly Report Generator
1. Review all files updated this week in /projects
2. Summarize key changes and progress
3. Identify blockers or delayed items
4. Create a formatted markdown report
5. Save to /reports/weekly-[date].md

Common Use Cases with Templates

For Product Managers

"Analyze all customer feedback files in the 'feedback' folder. Categorize feedback by: feature requests, bugs, UX issues, and praise. Create a prioritized list of the top 10 most mentioned items with frequency counts."

For Content Creators

"Review all draft articles in the 'drafts' folder. For each, assess completion status (ready, needs editing, needs research). Create a publication calendar suggestion based on topics and seasonal relevance."

For Consultants

"Process all client meeting notes from the past month. Extract action items, decisions made, and follow-up tasks. Create a client-by-client summary and a master task list."
