CGT: A Conceptual Framework for Prompt Injection Defense

Hollow_Prophecy · reddit · 2026-07-05

The author proposes a conceptual framework named CGT, which treats inputs as "constraint pressure" to be read before execution. It retains authenticated tasks and only allows capabilities bound to authorized inputs, serving as a defensive skill against prompt injection.

The core of the framework relies on "authorization chain validity, output residuals, and pressure inference" for diagnostics. It deliberately removes the intent/purpose layer to prevent anthropomorphism and teleological drift. Currently, it functions as a "pre-metric" diagnostic field rather than a strict metric, and includes transition zone mapping for agentic systems along with tool result container rules. This is an individual conceptual proposal without empirical validation yet.
