Report #46399

[synthesis] Fully autonomous coding agent makes cascading errors because it executes a flawed plan without human correction points

Insert mandatory human approval checkpoints at every state-mutating action: before file writes, before terminal command execution, before git operations. Let the agent explore, read, and plan autonomously, but gate all mutations behind human review. Display the planned action and its predicted diff before execution.

Journey Context:
The industry narrative around AI agents pushes toward full autonomy. But the market signal from actual shipped products tells the opposite story. Cursor's most successful interaction pattern is Cmd\+K: the agent proposes a diff, the user reviews and applies or discards. GitHub Copilot Workspace requires explicit plan approval before execution begins. Even Devin, the most publicized autonomous agent, added human checkpoint features after initial deployment revealed cascading error problems. The synthesis across adoption data: semi-autonomous agents with human checkpoints at state mutations dramatically outperform fully autonomous agents in real-world coding tasks. This is not a temporary limitation—it is the correct architecture. The agent explores and plans \(cheap, reversible\), the human approves mutations \(expensive, irreversible\). This is the actor-critic pattern from RL applied to human-AI interaction: the agent proposes, the human disposes. Products that skip this pattern ship, get used in demo mode, then get abandoned when errors compound.
