[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.

Prerequisites: MUST READ before executing:

Scan & Update Reference Doc — Read existing doc first, scan codebase for current state, diff against doc content, update only changed sections, preserve manual annotations. MUST READ .claude/skills/shared/scan-and-update-reference-doc-protocol.md for full protocol and checklists.

Quick Summary

Goal: Scan the project codebase and populate docs/project-reference/project-structure-reference.md with accurate service architecture, API ports, directory tree, tech stack, and module codes.

Workflow:

1. Read — Load current target doc, detect init vs sync mode
2. Scan — Discover services, apps, ports, tech stack via parallel sub-agents
3. Report — Write findings to external report file
4. Generate — Build/update the reference doc from report
5. Verify — Spot-check paths and ports

Key Rules:

• Generic — discover everything dynamically, never hardcode project-specific values
• Use docs/project-config.json for hints if available, fall back to filesystem scanning
• All examples must reference real files found in this project

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Scan Project Structure

Phase 0: Read & Assess

1. Read docs/project-reference/project-structure-reference.md
2. Detect mode: init (placeholder only) or sync (has real content)
3. If sync: note which sections exist and their line counts

Phase 1: Plan Scan Strategy

Check if docs/project-config.json exists for module lists and service maps. Plan these scan areas:

• Backend services — Find .csproj, Dockerfile, Program.cs, launchSettings.json for ports
• Frontend apps — Find angular.json, nx.json, package.json, vite.config, next.config
• Infrastructure — Find docker-compose.yml, Dockerfile, K8s manifests, CI/CD config
• Tech stack — Parse package.json dependencies, .csproj PackageReferences, build tool configs

Phase 2: Execute Scan (Parallel Sub-Agents)

Launch 3 Explore agents in parallel:

Agent 1: Backend Services

• Glob for **/*.csproj and **/Dockerfile to find services
• Grep launchSettings.json or appsettings*.json for port numbers
• Grep for [ApiController] or MapControllers to find API services
• List service directories with their ports

Agent 2: Frontend Apps

• Glob for **/angular.json, **/nx.json, **/package.json (not in node_modules)
• Find app entry points (main.ts, index.tsx, App.vue)
• Extract dev server ports from configs (serve commands, proxy configs)
• Identify framework versions from package.json

Agent 3: Infrastructure & Tech Stack

• Find docker-compose*.yml — extract service definitions and port mappings
• Find CI/CD configs (.github/workflows/*.yml, azure-pipelines.yml, Jenkinsfile)
• Parse primary package managers (package.json, *.csproj) for key dependencies
• Identify databases, message brokers, caching from connection strings or Docker services

Write all findings to: plans/reports/scan-project-structure-{YYMMDD}-{HHMM}-report.md

Phase 3: Analyze & Generate

Read the report file. Build these sections:

Target Sections

Content Rules

• Use tables for structured data (not prose)
• Include actual port numbers found in configs
• Directory tree: show only meaningful structure (skip node_modules, bin, obj)
• Tech stack: include version numbers from package.json/csproj

Phase 4: Write & Verify

1. Write updated doc with <!-- Last scanned: YYYY-MM-DD --> at top
2. Verify: spot-check 3 service paths exist on filesystem
3. Verify: port numbers match actual config files
4. Report: sections updated vs unchanged

Closing Reminders

• MUST break work into small todo tasks using TaskCreate BEFORE starting
• MUST search codebase for 3+ similar patterns before creating new code
• MUST cite file:line evidence for every claim (confidence >80% to act)
• MUST add a final review todo task to verify work quality MANDATORY IMPORTANT MUST READ the following files before starting:
• MUST READ .claude/skills/shared/scan-and-update-reference-doc-protocol.md before starting
