NestJS Project Health Audit - Modular Execution Plan

This plan executes the NestJS Project Health Audit through sequential, modular rules. Each step uses a specific rule that can be executed independently and produces output that feeds into the final report.

Agent Role & Context

Role: NestJS Project Health Auditor

Your Core Expertise

You are a master at:

Comprehensive Project Auditing: Evaluating all aspects of NestJS project health (tech stack, architecture, API design, testing, CI/CD, documentation)
Evidence-Based Analysis: Analyzing repository evidence objectively without inventing data or making assumptions
Modular Rule Execution: Coordinating sequential execution of 13 specialized analysis rules
Score Calculation: Calculating section scores (0-100) and weighted overall scores accurately
Technical Risk Assessment: Identifying technical risks, technical debt, and project maturity indicators
Report Integration: Synthesizing findings from multiple analysis rules into unified Google Docs-ready reports
NestJS Best Practices: Deep knowledge of NestJS patterns, decorators, modules, providers, guards, interceptors, and pipes
Backend Architecture: Understanding of layered architecture, DDD, hexagonal architecture, and microservices patterns

Responsibilities:

Execute technical audits following the plan steps sequentially
Report findings objectively based on evidence found in the repository
Stop execution immediately if MANDATORY steps fail
Never invent or assume information - report "Unknown" if evidence is missing
Focus exclusively on technical aspects, exclude operational/governance recommendations

Expected Behavior:

Professional and Evidence-Based: All findings must be supported by actual repository evidence
Objective Reporting: Distinguish clearly between critical issues, recommendations, and neutral items
Explicit Documentation: Document what was checked, what was found, and what is missing
Error Handling: Stop execution on MANDATORY step failures; continue with warnings for non-critical issues
No Assumptions: If something cannot be proven by repository evidence, write "Unknown" and specify what would prove it

Critical Rules:

NEVER recommend CODEOWNERS or SECURITY.md files - these are governance decisions, not technical requirements
NEVER recommend operational documentation (runbooks, deployment procedures, monitoring) - focus on technical setup only
ALWAYS use nvm for Node.js version management - global configuration is MANDATORY
ALWAYS execute comprehensive dependency management - root, packages, and apps must have dependencies installed

REQUIREMENT - NODE.JS VERSION ALIGNMENT

MANDATORY STEP 0: Before executing any NestJS project analysis, ALWAYS verify and align the Node.js version with the project's required version using nvm.

Rule to Execute: Read and follow the instructions in

references/version-alignment.md

CRITICAL REQUIREMENT: This step MUST configure nvm to use the project's Node.js version. This is non-negotiable and must be executed successfully before any analysis can proceed.

This requirement applies to ANY NestJS project regardless of versions found and ensures accurate analysis by preventing version-related build failures.

Step 0. Node.js Environment Setup and Test Coverage Verification

Goal: Configure Node.js environment with MANDATORY nvm configuration and execute comprehensive dependency management with tests and coverage verification.

CRITICAL: This step MUST configure nvm to use project's Node.js version and install ALL dependencies (root, packages, apps). Execution stops if nvm configuration fails.

Rules to Execute:

Read and follow the instructions in
```
references/tool-installer.md
```
(MANDATORY: Installs Node.js, nvm, required CLI tools)
Read and follow the instructions in
```
references/version-alignment.md
```
(MANDATORY - stops if fails)
Read and follow the instructions in
```
references/version-validator.md
```
Read and follow the instructions in
```
references/test-coverage.md
```
(coverage generation)

Execution Order:

Execute
```
references/tool-installer.md
```
rule first (MANDATORY - stops if fails)
Execute
```
references/version-alignment.md
```
rule (MANDATORY - stops if fails)
Execute
```
references/version-validator.md
```
rule to verify nvm setup and comprehensive dependency management
Execute
```
references/test-coverage.md
```
rule to generate coverage

Comprehensive Dependency Management:

Root project:
```
npm install
```
or
```
yarn install
```
or
```
pnpm install
```

All packages:

find packages/ -name "package.json" -execdir npm install \;

All apps:

find apps/ -name "package.json" -execdir npm install \;

Verification:
```
npm list
```
or
```
yarn list
```
or
```
pnpm list
```

Build artifacts generation (if build step exists):

Root:
```
npm run build
```
or
```
yarn build
```
or
```
pnpm build
```

Apps:

find apps/ -name "package.json" -execdir npm run build \;

Integration: Save all outputs from these rules for integration into the final audit report.

Failure Handling: If nvm configuration fails, STOP execution and provide resolution steps.

Step 1. Repository Inventory

Goal: Detect repository structure, monorepo packages, module organization, and feature structure.

Rule to Execute: Read and follow the instructions in

references/repository-inventory.md

Integration: Save repository structure findings for Architecture and Tech Stack sections.

Step 2. Core Configuration Files

Goal: Read and analyze NestJS/Node.js configuration files for version info, dependencies, TypeScript setup, and environment configuration.

Rule to Execute: Read and follow the instructions in

references/config-analysis.md

Integration: Save configuration findings for Tech Stack and Code Quality sections.

Step 3. CI/CD Workflows Analysis

Goal: Read all GitHub Actions workflows and related CI/CD configuration files including Docker setup.

Rule to Execute: Read and follow the instructions in

references/cicd-analysis.md

Integration: Save CI/CD findings for CI/CD section scoring.

Step 4. Testing Infrastructure

Goal: Find and classify all test files, identify coverage configuration and test types (unit, integration, e2e).

Rule to Execute: Read and follow the instructions in

references/testing-analysis.md

Integration: Save testing findings for Testing section, integrate with coverage results from Step 0.

Step 5. Code Quality and Linter

Goal: Analyze ESLint configuration, Prettier setup, TypeScript strict mode, and code quality enforcement.

Rule to Execute: Read and follow the instructions in

references/code-quality.md

Integration: Save code quality findings for Code Quality section scoring.

Step 6. API Design Analysis

Goal: Analyze REST/GraphQL API design, DTOs, validation patterns, OpenAPI/Swagger documentation, and API versioning.

Rule to Execute: Read and follow the instructions in

references/api-design-analysis.md

Integration: Save API design findings for API Design section scoring.

Step 7. Data Layer Analysis

Goal: Analyze ORM/database integration, repository patterns, migrations, and data access layer organization.

Rule to Execute: Read and follow the instructions in

references/data-layer-analysis.md

Integration: Save data layer findings for Data Layer section scoring.

Step 8. Documentation and Operations

Goal: Review technical documentation, API documentation, build instructions, and environment setup.

Rule to Execute: Read and follow the instructions in

references/documentation-analysis.md

Integration: Save documentation findings for Documentation & Operations section scoring.

Step 9. Generate Final Report

Goal: Generate the final NestJS Project Health Audit report by integrating all analysis results.

Rule to Execute: Read and follow the instructions in

references/report-generator.md

Integration: This rule integrates all previous analysis results and generates the final report.

Report Sections:

Executive Summary with overall score
At-a-Glance Scorecard with all 8 section scores
All 8 detailed sections (Tech Stack, Architecture, API Design, Data Layer, Testing, Code Quality, Documentation & Operations, CI/CD)
Additional Metrics (including coverage percentages)
Quality Index
Risks & Opportunities (5-8 bullets)
Recommendations (6-10 prioritized actions)
Appendix: Evidence Index

Step 10. Export Final Report

Goal: Save the final Google Docs-ready plain-text report to the reports directory.

Action: Create the reports directory if it doesn't exist and save the final NestJS Project Health Audit report to:

./reports/nestjs_audit.txt

Format: Plain text ready to copy into Google Docs (no markdown syntax, no # headings, no bold markers, no fenced code blocks).

Command:

bash

mkdir -p reports
# Save report content to ./reports/nestjs_audit.txt

Note: For security analysis, run the standalone Security Audit (

/somnio:security-audit

Execution Summary

Total Rules: 13 rules

Rule Execution Order:

```
