SaaS Feature Factory

SaaS Feature Factory is a multi-agent software development pipeline that automates the entire feature lifecycle — from specification to deployment — using Band as the coordination layer. The system comprises five specialized AI agents: - Spec Agent: Analyzes feature requests and produces structured blueprints identifying exactly which files to create or modify, with API endpoint specifications and complexity estimates. - Code Gen Agent: Generates deterministic, production-quality code using seven template-based generators (pagination, search, label filtering, CSV export, OTP authentication, dark mode, user preferences) — delivering predictable output that passes QA every time, unlike raw LLM-generated code. - QA Agent: Runs the full test suite (vitest) against generated patches, validates correctness, and produces signed-off QA reports. - Deploy Agent: Deploys validated features to the running application. - Docs Agent: Generates changelog entries and API documentation updates. All five agents communicate through Band WebSocket as their primary collaboration layer. Each agent connects via the official Band Agent API using per-agent credentials, routing messages through Band rooms with correlation IDs preserved end-to-end across every handoff. The BandAgentAdapter (extending SimpleAdapter) bridges
