Create an onboarding pack for a new team member
This Cowork prompt generates a complete, personalized onboarding kit from your internal documents. Claude analyzes your processes, documentation, and past packs to create: welcome guide, D1/W1/M1 checklist, first week schedule, and feedback template. Each file is saved in a dedicated folder for the new team member.
Sort and organize my Downloads folder
This Cowork prompt turns your messy Downloads folder into a clean, date-organized file structure. Claude directly accesses your files, identifies types, spots duplicates, and proposes a smart sorting plan. Each file is renamed with its modification date for chronological ordering. The process is safe: no deletion without your explicit approval. Perfect for a one-time cleanup or monthly routine.
Analyze a CSV file and generate a dashboard
This Cowork prompt transforms any CSV file into a structured analysis. Claude explores the data, cleans it, applies relevant analyses based on detected data type (sales, customers, marketing) and generates actionable insights. The report includes statistics, trends, and recommendations. Multiple exports (Markdown, cleaned CSV, JSON) facilitate follow-up work.
Create a pitch deck from my business plan
This Cowork prompt analyzes your business plan and condenses it into a 12-slide pitch deck ready for design. Claude extracts key data (market, traction, financials) and structures it in standard investor format. Each slide includes text content, talking points, and visual suggestions.
Clean up and structure my Google Drive
This prompt uses Cowork to audit and restructure your cloud storage from a file export. Claude analyzes the existing folder tree, identifies issues (duplicates, orphan files, deep folders) and proposes a new structure tailored to your work. It also generates naming conventions and a detailed migration plan.
Automate invoice generation
This Cowork prompt automates invoice generation from your service data (CSV, spreadsheet). Claude applies legal mentions, calculates VAT and totals, numbers sequentially, and saves each invoice in your file structure. The global summary and payment tracking update complete the billing process.
Prepare a complete meeting briefing
This prompt turns Claude Cowork into a meeting prep assistant. By analyzing your project folders, previous meeting notes, and documents, it generates a complete briefing: context, agenda, participant profiles, and strategic questions. Everything is based on your actual documents, not generalities. The briefing is saved as a file, ready for review.
Write standardized job descriptions
This Cowork prompt analyzes your existing listings to match your tone, then generates professional, standardized job descriptions. Each listing follows a proven structure: attractive context, concrete missions, flexible requirements, and transparent process. Inclusive writing rules and limited prerequisites ensure postings that attract maximum qualified candidates.
Create a weekly summary of my activities
This prompt leverages Cowork's ability to read and analyze your local files to compile an automatic weekly review. By scanning your notes, projects, and task files, Claude produces a structured summary with productivity metrics, project progress, and pending tasks. The result is saved directly as Markdown, ready to share with your team or archive.
Run automatic competitive intelligence
This Cowork prompt leverages your intelligence files (screenshots, notes, articles) to produce a structured competitive report. Claude cross-references sources to build a comparison matrix, identify each competitor's recent moves, and propose prioritized strategic recommendations. The report is saved and can serve as a basis for strategic meetings.
Analyze my website's SEO performance
This Cowork prompt transforms your raw Google Search Console exports into a structured, actionable SEO audit. Claude identifies quick-wins (pages in position 5-20 to optimize), problems (cannibalization, declining pages) and generates recommendations prioritized by impact and effort. The CSV tracking table enables continuous monitoring.
Convert my notes into structured documentation
This Cowork prompt gathers your scattered notes from a folder and transforms them into professional documentation. Claude identifies themes, detects inconsistencies and gaps, then produces a structured document with table of contents and cross-references. Incomplete sections are flagged for completion. Every piece of information cites its original source.
