Intent Debt Emerges as Costliest Risk in Agentic Engineering, With 20 Agents Multiplying Gaps

Summary
Intent debt—the missing written rationale behind software decisions—is framed as the most expensive form of debt in agentic engineering because AI can refactor code and explain systems, but cannot recover the original why.
Three debt types are separated: technical debt in code, cognitive debt in people, and intent debt in artifacts; only intent must be externalized for teammates, future maintainers, and agents to use reliably.
20 parallel agents can multiply that cost every session, since each starts cold and fills undocumented constraints with plausible guesses—turning missing rationale into repeated orchestration and rework overhead.
300ms debounce choices, guard clauses, queue-based architectures, and behavior-preserving refactors are cited as examples where green tests or clean diffs still fail to preserve the original intent.
AGENTS.md, lightweight ADRs, intent-focused specs, and session learnings are presented as the payoff path, reflecting a broader shift in software value from writing code to recording goals, constraints, and reasons.
