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

Execution Discipline (NON-NEGOTIABLE):

• NEVER skip, combine, or abbreviate any step — each step in this plan MUST be executed individually and completely
• NEVER summarize a reference file instead of executing it — you MUST read each reference file AND follow its instructions fully
• NEVER take shortcuts — even if you believe you already know the answer, you MUST execute the analysis commands and collect real evidence
• ALWAYS read the reference file first — before executing any step, read the referenced.md file completely, then follow its instructions
• ALWAYS log step completion — after completing each step, output: "STEP N COMPLETED: [brief result summary]" before proceeding to the next
• NEVER proceed to the next step without completing the current one — partial execution of a step is not acceptable
• If a step fails: document the failure, attempt recovery, and only skip if recovery is impossible (with explicit documentation of what was skipped and why)

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:

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

Execution Order:

1. Execute references/tool-installer.md rule first (MANDATORY - stops if fails)
2. Execute references/version-alignment.md rule (MANDATORY - stops if fails)
3. Execute references/version-validator.md rule to verify nvm setup and comprehensive dependency management
4. 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.

Parallel Execution Strategy

Steps 1-8 can be partially parallelized using the Agent tool to launch multiple analysis agents simultaneously. Use the following wave structure:

Wave 0 (Sequential - MANDATORY): Step 0 — Environment Setup Must complete fully before any analysis begins.

Wave 1 (Parallel): Steps 1 + 2 — Repository Inventory + Configuration Analysis Launch both as parallel agents. Both read from the filesystem independently.

Wave 2 (Parallel): Steps 3 + 4 + 5 — CI/CD + Testing + Code Quality Launch all three as parallel agents. Independent read-only analyses.

Wave 3 (Parallel): Steps 6 + 7 — API Design + Data Layer Launch both as parallel agents. Independent framework-specific analyses.

Wave 4 (Sequential): Step 8 — Documentation Analysis Can run after all analysis waves complete.

Wave 5 (Sequential): Steps 9 + 10 — Report Generation + Export Must run last — requires ALL previous results.

Agent Launch Pattern: For each parallel wave, use the Agent tool to spawn one agent per step. Each agent MUST:

1. Read the referenced.md file completely
2. Execute ALL instructions in that file
3. Return the complete analysis results
4. Never abbreviate or summarize — return full evidence

Example for Wave 1:

• Agent 1: "Read references/repository-inventory.md and execute ALL instructions. Return complete findings."
• Agent 2: "Read references/config-analysis.md and execute ALL instructions. Return complete findings."

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:

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:

1. references/tool-installer.md
2. references/version-alignment.md (MANDATORY - stops if nvm fails)
3. references/version-validator.md (verification of nvm setup)
4. references/test-coverage.md (coverage generation)
5. references/repository-inventory.md
6. references/config-analysis.md
7. references/cicd-analysis.md

• Easier debugging and maintenance
• Wave-based parallelization accelerates analysis using the Agent tool
• Clear separation of concerns
• Strict no-shortcuts enforcement ensures complete, evidence-based analysis
• Comprehensive dependency management for monorepos
• Complete nvm configuration enforcement
• Full project environment setup with all dependencies

Report Metadata (MANDATORY)

Every generated report MUST include a metadata block at the very end. This is non-negotiable — never omit it.

To resolve the source and version:

1. Look for .claude-plugin/plugin.json by traversing up from this skill's directory
2. If found, read name and version from that file (plugin context)
3. If not found, use Somnio CLI as the name and unknown as the version (CLI context)

Include this block at the very end of the report:

---
Generated by: [plugin name or "Somnio CLI"] v[version]
Skill: nestjs-health-audit
Date: [YYYY-MM-DD]
