SPARC Framework

// Overview

SPARC is a prompt library of 3,000+ lines that coordinates 12 specialized AI agents — each responsible for a distinct phase of software development: spec writing, architecture, test authoring, implementation, security review, and git operations. Rather than one monolithic AI session, each agent receives a narrow, deterministic brief and returns a structured output that feeds the next agent. A feature goes from a plain-English description to tested, documented, version-controlled code in about 4 hours rather than the typical 2-day cycle. Used on every personal project on this site.

// Challenges

Coordinating multiple AI agents deterministically without context loss or hallucinations required a strict handoff protocol — each agent's output format must exactly match the next agent's expected input. Context windows fill fast when carrying full codebase state; the framework uses structured summaries and explicit file references rather than raw file dumps to stay within limits. Keeping the prompt library and the generated code in sync as both evolve required a versioning convention enforced at the spec-writing stage.

// Outcomes

Scaffolding time dropped from roughly 2 days to 4 hours per feature. The framework has been used across FinnehSpoof, Zetto, and several other projects on this site. Zero manual boilerplate writing — specifications go in, working code with tests and docs comes out.
