12 Factor Apps Analysis

perform 12-Factor App compliance analysis on a codebase

12-Factor App Compliance Analysis

You are performing a comprehensive compliance analysis against the 12-Factor App methodology for building SaaS applications.

Use the 12-factor-apps skill to guide this analysis.

Target Codebase

Path: $ARGUMENTS (default: current working directory)

Analysis Scope

Evaluate all 12 factors:

1. Codebase - One codebase tracked in revision control, many deploys
2. Dependencies - Explicitly declare and isolate dependencies
3. Config - Store config in the environment
4. Backing Services - Treat backing services as attached resources
5. Build, Release, Run - Strictly separate build and run stages
6. Processes - Execute the app as one or more stateless processes
7. Port Binding - Export services via port binding
8. Concurrency - Scale out via the process model
9. Disposability - Maximize robustness with fast startup and graceful shutdown
10. Dev/Prod Parity - Keep development, staging, and production as similar as possible
11. Logs - Treat logs as event streams
12. Admin Processes - Run admin/management tasks as one-off processes

Workflow

1. Use the skill - Read the 12-factor-apps skill for search patterns
2. Run searches - Use grep patterns from the skill for each factor
3. Evaluate compliance - Strong/Partial/Weak per factor
4. Document evidence - File:line references for findings
5. Identify gaps - What's missing vs. 12-Factor ideal
6. Provide recommendations - Actionable improvements

Output Format

Executive Summary

Factor	Status	Key Finding
I. Codebase	Strong/Partial/Weak	[Summary]
II. Dependencies	Strong/Partial/Weak	[Summary]
...	...	...

Overall: X Strong, Y Partial, Z Weak

Detailed Findings

For each factor with gaps:

• Current State: What exists
• Evidence: File:line references
• Gap: What's missing
• Recommendation: How to improve

Priority Recommendations

1. High Priority - Critical gaps affecting scalability/reliability
2. Medium Priority - Improvements for better compliance
3. Low Priority - Nice-to-have optimizations

Rules

• Use the skill's search patterns systematically
• Provide file:line evidence for all findings
• Be honest about compliance levels (don't inflate)
• Focus on actionable recommendations
• Reference the official 12-Factor App methodology
