Agent Architecture: Arguments Should Be Looked Up, Never Generated
Jay299792458 · reddit · 2026-08-06
A developer introduced a new pre-execution checklist architecture for AI agents to prevent models from hallucinating missing parameters.
Core Mechanism:
- Provenance Chain Lookup: Instead of simply validating arguments, the system looks up the source of each parameter across a priority chain: useranswer → instruction → presetdata → measureddata → priorstate. Only if all five are empty is the field marked as unknown.
- Execution Gating: Unknown is treated as a valid state, not an error. If any unknown fields exist, the system blocks execution and asks the user, enforcing a "when unsure, ask" policy.
The author open-sourced the execution-state-preflight.js skeleton and invited the community to discuss scenarios where failing directly might be preferable to asking the user.
