The operating answer
Prompt injection becomes materially dangerous when untrusted content can influence access to powerful tools or sensitive data. Prompts and classifiers are defense layers; critical authorization must be deterministic and external to the model.
01
Untrusted content and trust labels
Turn the idea into a decision artifact with verified facts, explicit assumptions, unresolved unknowns, accountable owners, acceptance limits, and a review date. A precise-looking answer with weak evidence is less useful than a bounded conclusion with visible uncertainty.
The practical question is not whether a technology can produce an impressive output. It is whether the complete system improves the defined work under real conditions without shifting unacceptable cost, risk, or workload elsewhere.
02
Tool mediation
Treat identity, authorization, tool scope, destinations, data classification, budgets, and approval as machine-enforced policy inputs. Untrusted content can inform a plan but cannot grant authority or alter the control plane.

Context invalidation

Testing direct and indirect attacks

Questions to take into the next decision
- What process and business outcome are in scope?
- Which facts are verified and which assumptions still control the result?
- What is the simplest credible comparator?
- Which failure is unacceptable even if the average result is strong?
- Who owns operation, risk, approval, monitoring, and shutdown?
- What evidence would make us scale, revise, defer, replace, or stop?
