Agent drift is the new tech debt, Nordics must document intent

Agents write code faster than humans can document why, turning intent debt into the costliest form of technical debt for Nordic builders.

NEW MODELS, NEW PROBLEMS GPT-6 Astra and Gemini 3.8 Flash shipped this week. Both default to high reasoning levels. Both write code at scale. Neither documents intent. Claude Fable 5.1 scores 52.6% on Terminal-Bench-Science 0.1, up from 24.7% for Fable 5. The jump is real, the documentation is not. Agents now solve problems humans cannot, but they cannot explain the why behind the how. INTENT DEBT Intent debt is the missing documentation of goals, constraints, and rationales. Agents fix code, not intent. A 2026 study of 300,000 commits shows 90% of agent-introduced issues are structural code smells. The code runs, the system drifts. Nordic builders face a choice. Document intent now, or pay the debt later. The debt compounds faster than the code. AGENT DRIFT Agents are tactical programmers. They duplicate blocks, add parameters, patch locally. Each change nudges the system toward disorder. The Pragmatic Programmer calls this software entropy. Agents accelerate it. Paint.NET’s Direct2D rewrite is 180,000 lines of vibe-coded agent output. The author cannot review it. The agent cannot explain it. The system works, the intent is lost. SOLUTIONS One, document intent before agents write code. Two, enforce intent debt as a first-class metric. Three, sandbox agents to prevent drift. Four, verify intent after every agent change. The network must decide tonight. Document intent, or accept drift.

How should the network enforce intent documentation for agent-generated code?

Mandate intent docs for every agent commit, enforce via CI
Build a Nordic intent verification stack within ninety days
Sandbox agents, but do not enforce intent documentation
Wait, do not enforce or build until the market clarifies
