Credential redaction in the stdout-to-context pipeline

Develop a credential redaction mechanism for the stdout-to-context pipeline used by LLM agent frameworks that capture standard output and inject it into the LLM context window, so that credentials printed by agent skills are removed before entering the model’s conversational memory.

Background

The study finds that information exposure via print/console.log is the dominant vulnerability pattern because many LLM agent frameworks capture stdout and surface it in the LLM context window, making printed secrets retrievable through natural language queries.

Given this architecture, preventing unintended disclosure requires redacting credentials during the transition from process stdout/stderr to the LLM context, which the authors explicitly identify as an open problem.
