Analyze my website's SEO performance
This Cowork prompt transforms your raw Google Search Console exports into a structured, actionable SEO audit.

The CSV tracking table enables continuous monitoring.
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.
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.
Prepare a monthly financial report
This Cowork prompt generates a professional financial report from your accounting files (bank exports, invoices, tracking spreadsheets). Claude analyzes data, calculates KPIs, compares with previous month, and flags alerts. M+1 projections help with planning. Ideal for freelancers, small businesses, and startups without a CFO.
Turn a blog post into LinkedIn posts
This Cowork prompt reads your blog post directly and splits it into 5 distinct LinkedIn formats: controversial hook, framework, storytelling, statistic, and carousel. Each post is optimized for the LinkedIn algorithm with proper word count, targeted hashtags, and suggested publication slots. You get a full week of LinkedIn content from a single article.
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.
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.
Build a tech watch system
This Cowork prompt structures your tech watch by analyzing your scattered sources (saved articles, notes, newsletters, bookmarks). Claude identifies strong trends and weak signals, evaluates emerging tools, and checks updates for your tech stack. The personalized training plan helps prioritize your skill development.
Automate invoice generation

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.
Generate a project status report
This Cowork prompt automates project status report creation by analyzing your files: tasks, meeting notes, deliverables. Claude identifies progress, blockers, risks, and pending decisions. The report follows standard PMO format with visual health indicators. Saved as Markdown, it's ready for distribution to your team or management.
