AI instructions as platform infrastructure
In previous posts on the Ad Hoc LLC website, I’ve talked about how platforms reduce complexity by providing reusable building blocks and how AI-assisted code generation is transforming custom development. I think that there is an emerging opportunity that sits at the intersection of these two trends that warrants some attention: treating AI coding agent instructions as a core component of platform infrastructure itself.
From documentation to executable knowledge
Platform teams invest significant effort in creating documentation that helps application developers understand and use platform services. This documentation typically includes architecture diagrams, API references, code samples, best practices, security guidelines, and deployment instructions.
While this documentation is essential, it still places a burden on developers to read, interpret, and correctly apply this information. Even with excellent documentation, developers must synthesize information across multiple documents, translate examples to their specific use case, and navigate the gap between understanding and implementation.
This cognitive load, while reduced compared to starting from scratch, can still create friction in the development process. Developers need to spend time deciphering documentation rather than solving their unique business problems.
AI instructions as infrastructure
What if platform teams could encode their knowledge directly into AI coding agent instructions that developers could use immediately? Instead of providing documentation that developers must interpret, platforms would provide machine-readable instructions that AI agents can execute directly.
This represents a fundamental shift in how platform knowledge is packaged and delivered. In this model, AI coding agent instructions become a first-class component of platform infrastructure, alongside the other building blocks I’ve discussed in the past. Just as platforms provide deployment pipelines and monitoring services, they would also provide curated AI instructions that embody institutional knowledge about how to build on the platform.
Platform-provided AI instructions would codify the collective knowledge of the platform team, including how to organize code within the platform’s architecture, required security controls and their implementation patterns, how to connect to platform APIs and shared services, coding standards and testing approaches, and agency-specific business domain knowledge.
The developer experience transformed
For application developers, this would transform the experience of starting a new project. Instead of reading through multiple documentation pages, finding and adapting code examples, and setting up basic scaffolding manually, developers would provide their AI coding assistant with the platform’s instruction set, describe their specific application needs, and focus immediately on unique business logic.
The AI agent, armed with platform-specific instructions, would generate code that already incorporates correct platform integration patterns, required security controls, proper configuration for deployment, and compliance with platform governance.
This approach dramatically reduces cognitive load on product teams in several ways. Developers don’t need to mentally process and translate documentation—the AI agent handles the interpretation and application of platform knowledge. Every project starts with the correct patterns and practices baked in. New team members can become productive more quickly, as the AI agent acts as an expert guide. And teams can spend their mental energy on the aspects of their application that make it unique, rather than on boilerplate integration with the platform.
Implementation considerations
For platform teams looking to adopt this approach, several factors are important.
- AI instructions should be versioned alongside platform releases, ensuring developers use guidance that matches their platform version.
- Platform teams should validate that instructions generate code that actually works correctly on the platform, treating instructions as code that requires testing. Instructions will improve over time based on feedback from developers and analysis of what the AI agents produce.
AI instructions can’t (and shouldn’t) replace documentation entirely. They would complement it by making knowledge executable while documentation remains important for deeper understanding. And in secure government environments, access to detailed platform instructions may need to be controlled, ensuring only authorized developers can use them.
The broader impact
This evolution of platforms has implications beyond individual developer productivity. New agencies or teams adopting a platform can become productive faster when AI instructions encode platform expertise. Institutional knowledge about platform best practices becomes more durable when encoded in AI instructions rather than living only in documentation or team members’ heads. Organizations can achieve greater consistency across applications when the same AI instructions guide initial implementation.
When AI-generated scaffolding already incorporates required security controls and compliance patterns, the path to ATO becomes even faster. And platform teams can support more application teams without proportionally increasing support burden, as AI instructions scale knowledge delivery.
A natural evolution
AI coding agent instructions represent a natural next step in platform evolution. Platforms have always been about encoding solutions to common problems so teams don’t reinvent the wheel. Documentation and code samples were the first generation of this encoded knowledge. AI instructions are the next generation—knowledge that isn’t just readable but directly executable.
For government agencies navigating the dual mandate to adopt commercial solutions and leverage AI capabilities, this approach offers a practical path forward. Platform foundations provide the commercial infrastructure, traditional documentation ensures understanding and oversight, and AI instructions dramatically accelerate the development of agency-specific applications on that foundation.
The result is a platform that doesn’t just provide services but actively helps developers use those services correctly and efficiently. It’s an approach that makes the right way not just the easiest way, but increasingly the automatic way—freeing government product teams to focus on what matters most: delivering value to the people who depend on government digital services.
