NaCl

NaCl (reading as Natrium Chloride) is an open-source full-SDLC framework, and its core innovation is how it solves the hardest problem in agentic development: storing and retrieving project knowledge. Instead of markdown specs that agents must re-read every session, all project knowledge — requirements, architecture decisions, entities, rules, and their relationships — lives in a Neo4j knowledge graph as first-class queryable objects. The measured effect: planning a single use case takes ~550 tokens (one targeted Cypher query) instead of ~150,000 tokens (reading a ~70-file markdown spec, because the agent doesn't know in advance where the relevant facts live) — a 99.6% reduction in context per use case, repeated in every planning session.
