Report #75188

[synthesis] Agent gradually adopts incorrect assumptions or persona shifts over long autonomous runs

Periodically compute the semantic distance of the agent's recent context \(read files, logs\) against its system prompt. If the context heavily contradicts the system prompt's persona or constraints, inject a system interrupt to re-anchor the agent.

Journey Context:
Agents reading logs or user files to debug will inevitably ingest text that contains instructions, frustrated user comments, or adversarial patterns. Over a long session, this accumulated data acts as a subtle prompt injection, shifting the agent's tone or making it overly cautious or aggressive. It does not fail a tool call; it just changes its decision-making boundary. Teams miss this because they monitor the semantic content of the outputs, not the slow drift of the inputs relative to the system prompt.
