Context Fundamentals

muratcankoylan/agent-skills-for-context-engineering

This is the conceptual foundation for the entire context engineering collection. It explains what context actually is (system prompts, tool definitions, retrieved documents, message history, tool outputs), how attention mechanics constrain agent behavior (the U-shaped attention curve, the n-squared relationship problem), and why quality beats quantity when you're working against a finite budget. Use it for onboarding, design decisions, and grounding operational work in first principles. It deliberately routes execution elsewhere: debugging attention failures to context-degradation, token efficiency to context-optimization, conversation summarization to context-compression. The four core principles (informativity over exhaustiveness, position-aware placement, progressive disclosure, iterative curation) are the mental models you need before touching the specialized skills.

Context Engineering Fundamentals

Context is the complete state available to a language model at inference time: system instructions, tool definitions, retrieved documents, message history, and tool outputs. Context engineering is the discipline of curating the smallest high-signal token set that maximizes the likelihood of desired outcomes.

This skill is the conceptual foundation that every other skill in the collection builds on. It explains what context is, how attention mechanics work, why context quality matters more than quantity, and the mental models needed to interpret every other context-engineering decision. It does not own operational work: debugging attention failures belongs to context-degradation, token-efficiency tactics belong to context-optimization, conversation summarization belongs to context-compression, file-based offloading belongs to filesystem-context, and project-shape decisions belong to project-development.
