A Field Guide for Moving from Demo to Deployment

In the "Decade of Agents," the difference between a toy and a tool is rigour. Use this checklist to evaluate whether your autonomous system is ready to handle the compounding error rates of the real world.

Phase I: Architectural Integrity

Stop asking generalists to do specialist work.

• The Specialist Test: Have you decomposed the workflow into discrete steps?

  • Requirement: Ensure no single agent is responsible for more than 3 distinct logical jumps (e.g., extracting data to reasoning to formatting).

• Horizon Analysis: Have you calculated the theoretical failure rate?

  • Action: Map the total steps ($n$) and estimated per-step accuracy ($p$). If p^n < 0.90, the architecture must be refactored into shorter chains.

• Context Containment: Is the context window sanitized between steps?

  • Action: Ensure Agent B receives only the necessary output from Agent A, not the entire conversational history, to prevent "hallucination snowballing."

Phase II: The Trust Engine (Verification)

Math is for calculators; reasoning is for models.

• Deterministic Fallback: Are calculations and data lookups handled by code?

  • Requirement: Zero tolerance for LLMs performing arithmetic. Ensure Python/SQL tools are triggered for all quantitative tasks.

• The "Reviewer" Loop: Is there a secondary model acting as a critic?

  • Action: Implement a separate agent instance prompted solely to critique the output of the primary agent against a rubric (e.g., "Does this violate MAS guidelines?").

• Unit Testing for Prompts: Do you have a "Golden Set" of evaluation data?

  • Requirement: A fixed dataset of 50+ edge cases (e.g., malformed invoices, ambiguous dates) that the agent must pass with 100% accuracy before deployment.

Phase III: The Interface of Truth

Transparency is the prerequisite for trust.

• The Chatbot Ban: Is the interface structured?

  • Requirement: Replace chat streams with structured dashboards, tables, or document views.

• Traceability: Can a human audit the "thought process"?

  • Action: The UI must display the "Chain of Thought" (the reasoning trace) alongside the final output, allowing an auditor to verify the logic, not just the result.

• The "Human Brake": Is there an explicit intervention point?

  • Action: For high-stakes actions (e.g., executing a bank transfer), the system must pause for human confirmation.

Phase IV: Forward Deployment (The Singapore Standard)

The map is not the territory.

• SOP Excavation: Have you interviewed the staff, not just the managers?

  • Action: Identify at least 3 "unwritten rules" or implicit workflows that are not in the official documentation but are essential for the process.

• The "Red Teaming" Session: Have you intentionally tried to break it?

  • Action: Spend one full cycle feeding the agent contradictory or noisy data to test its error-handling capabilities.
