TL;DR: As software teams shift from manual coding to AI-guided implementation, the product requirements document is re-emerging as the control surface that reduces ambiguity, architectural drift, and hallucination-driven errors, according to SafeBreach. The practical shift is that specification quality now governs implementation quality, so governance has moved upstream from code review to planning discipline.
NHIMG editorial — based on content published by SafeBreach: How the PRD Has Become the New Code in an AI-First Development Process
Questions worth separating out
Q: How should teams govern AI-assisted coding when the model writes most of the implementation?
A: Teams should govern the specification first, then the code.
Q: Why do AI coding agents need more detailed requirements than human developers usually do?
A: Because the model fills gaps instead of asking clarifying questions like a senior engineer would.
Q: What breaks when a PRD is treated as a one-time planning document?
A: The implementation trail breaks.
Practitioner guidance
- Make the PRD the authoritative task record Require the PRD to hold mission scope, architecture, risks, tests, and implementation state before code generation begins, then treat it as the source of truth during delivery.
- Update requirements after every implementation phase Do not let an AI-assisted task run as a single opaque block.
- Tie sign-off to documented acceptance criteria Force definition of done, testing strategy, and explicit exit criteria into the PRD so the human reviewer can validate what the agent was supposed to build, not just what it produced.
What's in the full article
SafeBreach's full blog covers the operational detail this post intentionally leaves for the source:
- The 14-section PRD structure the team uses to keep AI-assisted implementation resumable and reviewable.
- The phase-by-phase workflow for updating the PRD after each implementation step and before pull request submission.
- The practical criteria the team uses to decide when a task is too large for a human-agent pair to keep aligned.
- The examples of status, risk, and testing sections that turn the PRD into an execution artifact rather than a note set.

Specification governance is becoming a security control, not a project preference. When AI agents generate implementation from structured prompts and living requirements, the specification determines whether the resulting software is aligned or fragile. That changes the governance burden for engineering and security leaders because ambiguity now shows up as implementation risk before code review ever begins. The lesson is that control quality has moved upstream into the requirements process.
A question worth separating out:
Q: How can security and engineering leaders tell whether AI-first delivery is under control?
A: Look for current PRDs with explicit scope, phase status, test expectations, and reconciliation after each implementation step. If those artefacts are stale, incomplete, or disconnected from the code, the team has no reliable governance record. The control signal is document fidelity, not coding speed.
