What problem does it solve?
Feed agents the right information at the right time. Context is the single biggest lever for agent output quality — too little and the agent hallucinates, too much and it loses focus. Context engineering is the practice of deliberately curating what the agent sees, when it sees it, and how it's structured.
Core Features & Use Cases
- Structure context from most persistent to most transient: Rules Files (CLAUDE.md, etc.), Spec / Architecture Docs, Relevant Source Files, Error Output / Test Results, Conversation History.
- Level-based loading: Level 1 — Rules Files; Level 2 — Specs/Architecture; Level 3 — Relevant Source Files; Level 4 — Error Output / Test Results; Level 5 — Conversation History.
- Practical guidance for starting fresh sessions, recovering output quality, and switching between codebase areas.
Quick Start
Start a session with a project-wide rules file and a feature-specific spec loaded, then gradually add relevant source files as tasks evolve.
