What problem does it solve? AI coding agents hallucinate APIs, ignore project conventions, and degrade in quality during long sessions because they receive too little, too much, or stale context. This Skill provides a systematic method for curating what the agent sees at each stage of a session. ## Core Features & Use Cases - Context Hierarchy Setup: Structures context into five levels from persistent rules files (CLAUDE.md, .cursorrules, AGENTS.md) down to transient conversation history, with templates for each. - Context Budget Management: Defines a 75% capacity trimming threshold, cut-first/protect lists, and compression-before-deletion strategies to prevent abrupt quality drops in long sessions. - Confusion Management: Provides explicit patterns for surfacing spec conflicts, missing requirements, and inline planning instead of silently guessing. - Use Case: When starting a new project for AI-assisted development, use this Skill to write a rules file covering tech stack, commands, conventions, and boundaries so the agent follows project patterns from the first prompt. ## Quick Start Ask the agent to create a CLAUDE.md rules file for your project covering tech stack, build commands, code conventions, and boundaries using the context engineering guidelines.
