What problem does it solve?
Context engineering prevents agent hallucinations and drift by ensuring the AI sees the right project information at the right time, reducing incorrect code edits and wasted iterations. It addresses both too-little context (missing APIs, invented behavior) and too-much context (loss of focus, stale instructions).
Core Features & Use Cases
- Persistent Rules Files: Define project-wide conventions, tech stack, commands, and boundaries to keep agents aligned across sessions.
- Selective Context Loading: Load only the relevant spec sections and source files for a task to maintain focus and reduce noise.
- Iteration Feedback: Feed targeted error output and test failures back to the agent and compact conversation history to avoid stale context.
- Use Case: Start a feature task by loading the project's rules file, the authentication spec excerpt, the related source and test files, then ask the agent to propose a plan before executing changes.
Quick Start
Use context-engineering to create or update a project rules file, load the minimal spec section and related source files for the task, and ask the agent to propose a short plan before making edits.
