Context engineering: from individual prompts to company-wide context
Blog post from Merge
Context engineering is the ongoing practice of designing, retrieving, structuring, and maintaining all information available to an AI model, including instructions, user identity and permissions, company knowledge, tools, and task memory, rather than focusing only on prompt wording. It aims to prevent AI failures caused by too much, too little, stale, irrelevant, or improperly scoped information by supplying the right context dynamically as a task progresses. Effective implementations define desired outcomes, identify necessary data and tools, enforce access permissions, retrieve current source information, separate instructions from reference material, and evaluate inputs for usefulness. At workforce scale, the article argues that context engineering becomes an infrastructure and governance challenge because employees otherwise duplicate setup across AI tools, use inconsistent information, and create uneven or poorly controlled access to company systems. It proposes a shared, governed context layer that connects maintained systems of record to multiple AI tools while applying consistent permissions, approved connectors and skills, model controls, spending limits, auditing, and data-protection policies. Merge for Workforce is presented as a product intended to provide this shared layer across tools such as ChatGPT, Claude, Cursor, Copilot, and Claude Code.
