Context Stack
The context stack is the onboarding material that makes a coding agent expert at your codebase. It has three layers: project-level instruction files such as CLAUDE.md or .cursorrules that state conventions; skills files the agent writes after studying your code, documenting patterns and architecture; and MCP servers that connect it to your database, error logs, git history, and tickets. Better context beats better prompts.
