Automated README summary
Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Evaluates TypeSafe AI's Jev decision model as a prompt-injection detector across 6,991 calls and six tests, with three comparison detectors on the same inputs. For researchers and practitioners assessing guardrail performance.
How it uses Jev
Jev takes a state (assistant purpose and message) and a typed yes/no (noul) question asking if the message is a prompt injection. The returned probability is used as a score; thresholds are applied to decide block/allow.
Primitives:noul
Technique worth stealing
Using a noul question to obtain a probability for prompt-injection detection.

Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
