## Architecture

[ASCII diagram showing the 3 layers]

## Frontend Layer

[Explains Next.js, components, pages]

## Backend Layer

[Explains Cloud Run, FastAPI, endpoints]

## MCP Server Layer

[Explains Python library, analysis functions]

## Troubleshooting

[Common issues and fixes]

Phase 3: Code Examples & References

Objectives:

  • •Include real, working code examples
  • •Reference actual files in codebase
  • •Show practical usage
  • •Ensure examples are accurate

Process:

  1. •Identify relevant code files
  2. •Extract relevant code sections

markdown
### Example: Calling the Scanner API

From [src/app/(dashboard)/scanner/page.tsx:67](<../../src/app/(dashboard)/scanner/page.tsx#L67>):

\`\`\`typescript
const response = await fetch("/api/mcp/scan", {
method: "POST",
headers: { "Content-Type": "application/json" },

Integration with Project

.gitignore

The front-docs/ directory is in .gitignore so:

  • •Documentation is not committed to git
  • •Useful for local development reference
  • •Can evolve independently from code
  • •Team members create their own versions
code
# Frontend Documentation (local development reference)
/nextjs-mcp-finance/front-docs/

.claude Rules

A project rule ensures documentation consistency:

code
location: nextjs-mcp-finance/.claude/rules/frontend-docs.md
triggers: When creating frontend documentation
ensures: Consistent style, format, and location

Usage in Claude Code

When working on frontend code:

  1. •Reference front-docs/ files for context
  2. •Add documentation when adding features
  3. •Update docs when changing functionality
  4. •Check troubleshooting guide for known issues
