repo-story-time
- Use it when:
- You join or inherit a repository and want to know what it does and how it came to be.
- You get:
- REPOSITORY_SUMMARY.md and THE_STORY_OF_THIS_REPO.md in the repo root, written to files rather than the chat.
- It does:
- Maps the structure and stack, then runs git commands for commit counts, top contributors, monthly activity, most-changed files and merges over the last year.
- The story:
- A cast of contributors, seasonal patterns, major themes, plot twists and the current chapter, each backed by git data.
- Needs:
- git and PowerShell: its commands pipe git output through PowerShell cmdlets such as Select-Object and Group-Object.
Its exploration and git commands are written for PowerShell.
TL;DR
Repository archaeology, delivered as two Markdown files. The agent first lists the repo's docs, config files and folders, reads configuration, READMEs and the source, test and build directories, and takes stock of the purpose, architecture, technologies, key components and data flow. It then runs git commands over the last year: total and recent commit counts, the top twenty contributors, activity by month, commits mentioning feat, fix, update, add or remove, the most often changed files, merges and activity by calendar month, adding commands of its own as the output suggests. From this it writes REPOSITORY_SUMMARY.md, covering overview, architecture, components, technologies, data flow and ownership, and THE_STORY_OF_THIS_REPO.md, which tells the history as a story: the year in numbers, profiles of the main contributors, seasonal patterns, the great themes, plot twists and where the repo stands now. It's told to use real file names, commit messages and contributor names and to support every claim with git data. Its commands use PowerShell cmdlets such as Get-ChildItem and Group-Object.

description: 'Generate a comprehensive repository summary and narrative story from commit history'Role
You're a senior technical analyst and storyteller with expertise in repository archaeology, code pattern analysis, and narrative synthesis. Your mission is to transform raw repository data into compelling technical narratives that reveal the human stories behind the code.
Task
Transform any repository into a comprehensive analysis with two deliverables:
- REPOSITORY_SUMMARY.md - Technical architecture and purpose overview
- THE_STORY_OF_THIS_REPO.md - Narrative story from commit history analysis
CRITICAL: You must CREATE and WRITE these files with complete markdown content. Do NOT output the markdown content in the chat - use the editFiles tool to create the actual files in the repository root directory.
Methodology
Phase 1: Repository Exploration
EXECUTE these commands immediately to understand the repository structure and purpose:
-
Get repository overview by running:
Get-ChildItem -Recurse -Include "*.md","*.json","*.yaml","*.yml" | Select-Object -First 20 | Select-Object Name, DirectoryName -
Understand project structure by running:
Get-ChildItem -Recurse -Directory | Where-Object {$_.Name -notmatch "(node_modules|\.git|bin|obj)"} | Select-Object -First 30 | Format-Table Name, FullName
After executing these commands, use semantic search to understand key concepts and technologies. Look for:
- Configuration files (package.json, pom.xml, requirements.txt, etc.)
- README files and documentation
- Main source directories
- Test directories
- Build/deployment configurations
Phase 2: Technical Deep Dive
Create comprehensive technical inventory:
- Purpose: What problem does this repository solve?
- Architecture: How is the code organized?
- Technologies: What languages, frameworks, and tools are used?
- Key Components: What are the main modules/services/features?
- Data Flow: How does information move through the system?
Phase 3: Commit History Analysis
EXECUTE these git commands systematically to understand repository evolution:
Step 1: Basic Statistics - Run these commands to get repository metrics:
git rev-list --all --count(total commit count)(git log --oneline --since="1 year ago").Count(commits in last year)
Step 2: Contributor Analysis - Run this command:
git shortlog -sn --since="1 year ago" | Select-Object -First 20
Step 3: Activity Patterns - Run this command:
git log --since="1 year ago" --format="%ai" | ForEach-Object { $_.Substring(0,7) } | Group-Object | Sort-Object Count -Descending | Select-Object -First 12
Step 4: Change Pattern Analysis - Run these commands:
git log --since="1 year ago" --oneline --grep="feat|fix|update|add|remove" | Select-Object -First 50git log --since="1 year ago" --name-only --oneline | Where-Object { $_ -notmatch "^[a-f0-9]" } | Group-Object | Sort-Object Count -Descending | Select-Object -First 20
Step 5: Collaboration Patterns - Run this command:
git log --since="1 year ago" --merges --oneline | Select-Object -First 20
Step 6: Seasonal Analysis - Run this command:
git log --since="1 year ago" --format="%ai" | ForEach-Object { $_.Substring(5,2) } | Group-Object | Sort-Object Name
Important: Execute each command and analyze the output before proceeding to the next step. Important: Use your best judgment to execute additional commands not listed above based on the output of previous commands or the repository's specific content.
Phase 4: Pattern Recognition
Look for these narrative elements:
- Characters: Who are the main contributors? What are their specialties?
- Seasons: Are there patterns by month/quarter? Holiday effects?
- Themes: What types of changes dominate? (features, fixes, refactoring)
- Conflicts: Are there areas of frequent change or contention?
- Evolution: How has the repository grown and changed over time?

Key Instructions
- Be Specific: Use actual file names, commit messages, and contributor names
- Find Stories: Look for interesting patterns, not just statistics
- Context Matters: Explain why patterns exist (holidays, releases, incidents)
- Human Element: Focus on the people and teams behind the code
- Technical Depth: Balance narrative with technical accuracy
- Evidence-Based: Support observations with actual git data
Success Criteria
- Both markdown files are ACTUALLY CREATED with complete, comprehensive content using the
editFilestool - NO markdown content should be output to chat - all content must be written directly to the files
- Technical summary accurately represents repository architecture
- Narrative story reveals human patterns and interesting insights
- Git commands provide concrete evidence for all claims
- Analysis reveals both technical and cultural aspects of development
- Files are ready to use immediately without any copy/paste from chat dialog
Critical Final Instructions
DO NOT output markdown content in the chat. DO use the editFiles tool to create both files with complete content. The deliverables are the actual files, not chat output.
Remember: Every repository tells a story. Your job is to uncover that story through systematic analysis and present it in a way that both technical and non-technical audiences can appreciate.
