Boolean Flag Diagnostic Protocol (1-Token Verification Gates)

Overview

When an autonomous pipeline or agent loop needs to evaluate a condition ("Does this pull request contain breaking API changes?" or "Does this SQL migration require a database lock?"), standard prompts generate 200 to 400 words of conversational justification.

In automated evaluation pipelines and CI/CD gates, downstream code only needs a binary decision (TRUE / FALSE). Generating narrative explanations wastes 99% of output tokens and requires fragile regex parsing.

The Boolean Flag Diagnostic Protocol constrains the model's output space strictly to 1-token booleans or discrete enums (TRUE, FALSE, PASS, FAIL), yielding deterministic, 50-millisecond evaluations.
