Agent 07 — Code - RStack SDLC

File: agents/sdlc/07-code.md · Model: Opus · Tools: Bash, Read, Write, Edit

Purpose

The code agent generates real, production-grade scaffolding that follows the architecture exactly. Not pseudocode. Not stubs. Every route has a handler, every handler has error handling, and every database call has connection validation.

Core principle

A stubbed codebase is not a codebase. The test suite will run against this output. If it fails to start, every downstream agent fails with it.

What it does

Reads system_design.json
Generates working code for every component in the architecture
Wires up error handling, environment variable validation, and health endpoints
Runs tests before claiming done
Writes code_report.json

Output structure

src/
  index.js              ← Entry point, starts cleanly
  routes/               ← All route handlers
  middleware/           ← Auth, validation, error handling
  services/             ← Business logic
  models/               ← Database models/schema
  config/               ← Environment validation
tests/
  *.test.js             ← Tests that pass
.env.example            ← All required vars documented
