What is "cumulative prompting" and how is it structured in this script?

Cumulative prompting is a method of building an AI's context in stages, where each subsequent level of instruction retains all previous information while adding new, more complex layers. In this specific script, the process is divided into four conditions: Condition A provides the baseline study and ID; Condition B adds a specific JSON schema and risk-of-bias criteria; Condition C introduces "training material" or methodological textbooks; and Condition D adds a "worked example" featuring a completed assessment of a separate study to serve as a gold-standard reference for the model.

How does the script ensure the AI's output is scientifically accurate and valid?

The script employs a "guilty until proven innocent" approach to AI responses through a strict validation gate. After the model generates a response, the script parses the JSON to ensure it matches the required schema and verifies that the `study_id` in the output matches the input study to prevent hallucinations. Furthermore, the script requires the AI to provide a "verbatim quote" from the PDF for every judgment made, forcing the model to anchor its scientific claims in the actual text of the study.

Why does the script use a "PROMPT_BRIDGE" and temperature set to zero?

The `PROMPT_BRIDGE` is a specific string used as a linguistic marker to help the model transition from reading training materials or examples to performing the actual task on the target study, which is crucial for maintaining focus in long-context windows. Setting the temperature to zero ensures the model's output is deterministic and consistent rather than creative. In a research context, this "boring" consistency is preferred because it prioritizes accuracy and reproducibility over varied or "fun" responses.

How does the script handle failures or errors during the assessment process?

The script uses a robust two-strike system for errors. If a response fails to parse or validate on the first attempt, the script logs the error and automatically tries a second time. If it fails again, the script records the failure in a detailed CSV log (`parse_failures.csv`) including the study ID, model used, and the specific error message. This allows researchers to audit the process and identify if certain models or prompts are consistently struggling with specific types of data.

What is the "PromptAssetResolver" and why is it used?

The `PromptAssetResolver` is a dynamic discovery tool that allows the script to find necessary files—like training PDFs or example JSONs—without the researcher having to hardcode every file path. It uses a scoring system to search through directories for keywords like "mulder" or "green" to identify the best-fit materials for the prompt. This makes the script flexible and portable, allowing different researchers to use the same logic even if their file naming conventions vary slightly, while still "failing loudly" if it finds ambiguous or conflicting files.

Automating Bias With Precision Logic

Nia: You know, I was just looking at this script for running risk-of-bias assessments, and it’s wild how much is going on under the hood. It’s not just sending a PDF to an AI; it’s this incredibly structured pipeline using the Gemini API to evaluate scientific studies.

0:16

Eli: Exactly! What’s really fascinating is that it doesn’t just use one prompt. It actually builds them cumulatively through four different conditions, labeled A through D. By the time you get to Condition D, the script is feeding the model the study PDF, training materials, and even a full worked example with expected JSON output.

0:36

Nia: Right, and it’s all strictly validated. If the JSON doesn't match the schema or if the model gets the study ID wrong, the script catches it and even tries a second time.

0:46

Eli: It’s a very robust way to handle automated research synthesis. Let’s break down exactly how those four prompt conditions work.
