01Executive Overview
Kavach is a self-improving development harness for AI coding agents that enforces engineering discipline through lifecycle gates, maintains persistent cross-session memory in SurrealDB, and builds a knowledge graph that learns from every mistake.
02The Engineering Challenge
Operational Problem & Constraints
Critical friction and failure modes observed in existing workflows
AI coding agents are powerful but stateless between sessions and easily slip into anti-patterns: asking permission instead of acting, skipping research, repeating past mistakes, and leaving work half-done without verification.
03Architecture & Technical Solution
System Architecture & Algorithmic Design
Engineering methodology, model selection, and pipeline design
Kavach fixes this with a Rust hook engine that runs at every lifecycle event. It enforces 3-witness verification gates, maintains persistent memory in SurrealDB, auto-recalls relevant decisions on every prompt, compresses injections at chokepoints, and prevents destructive actions before execution.
04Quantified Impact & Benchmarks
Empirical Outcomes & Performance Metrics
Validated benchmarks, latency figures, and operational efficiency
Kavach transforms AI agent development from stateless, error-prone sessions into a self-improving system that enforces best practices, maintains memory across sessions, and continuously learns from its mistakes.
