TOOL 03 // ARCHITECTURAL SIZING RUBRIC

Agent-or-Workflow Decision Tool

Most business problems do NOT need an AI agent. This diagnostic rubric evaluates your input structure, risk tolerance, and rules to recommend the simplest, most reliable technology choice.

5 Diagnostic QuestionsAnti-Hype Sizing

1. How does your incoming data arrive?

2. Are the decision rules fixed or subjective?

3. What is your tolerance for algorithmic variance?

4. Primary task action required:

Architectural Recommendation (Estimate)

Hybrid Pipeline

Why this option:A hybrid architecture is best: use an LLM parser strictly for data extraction and normalization into JSON, then hand off execution to a 100% deterministic rule engine with human approval on high-value exceptions.

Complexity Score:Medium

Running Cost / Month:$40 - $180 (LLM tokens)

Failure Probability:Gated by supervisor check

Rubric rule: Recommends the simplest reliable option per Vanthrope engineering standard.
