GitHub reveals three sensible strategies for builders to enhance AI coding outputs via customized directions, reusable prompts, and specialised brokers.
GitHub is pushing builders to maneuver past fundamental prompting with a brand new framework it calls context engineering—a scientific method to feeding AI coding assistants the appropriate info on the proper time. The steerage, revealed January 12, 2026, outlines three particular methods for getting higher outcomes from GitHub Copilot.
The idea represents what Braintrust CEO Ankur Goyal describes as bringing “the appropriate info (in the appropriate format) to the LLM.” It is much less about intelligent phrasing and extra about structured information supply.
Three Methods That Really Work
Harald Kirschner, principal product supervisor at Microsoft with deep VS Code and Copilot experience, laid out the method at GitHub Universe final fall. The three strategies:
Customized directions let groups outline coding conventions, naming requirements, and documentation kinds that Copilot follows robotically. These reside in .github/copilot-instructions.md recordsdata or VS Code settings. Assume: how React elements must be structured, how errors get dealt with in Node companies, or API documentation formatting guidelines.
Reusable prompts flip frequent duties into standardized instructions. Saved in .github/prompts/*.prompts.md, these might be triggered through slash instructions like /create-react-form. Groups use them for code evaluations, take a look at era, and mission scaffolding—identical execution each time.
Customized brokers create specialised AI personas with outlined tasks. An API design agent evaluations interfaces. A safety agent handles static evaluation. A documentation agent rewrites feedback. Every can embody its personal instruments, constraints, and conduct fashions, with handoff functionality between brokers for complicated workflows.
Why This Issues Now
Context engineering has gained important traction throughout the AI business all through early 2026, with a number of enterprise-focused discussions rising in the identical week as GitHub’s steerage. The self-discipline addresses a elementary limitation: LLMs carry out dramatically higher when given structured, related background info relatively than uncooked queries.
Retrieval Augmented Technology (RAG), reminiscence methods, and power orchestration all fall below this umbrella. The purpose is not simply higher code output—it is decreasing the back-and-forth prompting that kills developer move.
For groups already utilizing Copilot, the sensible upside is consistency throughout repositories and sooner onboarding. New builders inherit the context engineering setup relatively than studying tribal information about “the best way to immediate Copilot appropriately.”
GitHub’s documentation contains setup guides for every method, suggesting the corporate sees context engineering as a core competency for AI-assisted growth going ahead.
