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:

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

Workflow

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

High Priority - Critical gaps affecting scalability/reliability
Medium Priority - Improvements for better compliance
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
