Trajectory Poisoning in Self-Evolving Agent Skills

Published 8/6/2026

Analyzed 8/13/2026

Self-evolving agent-skill systems may promote recurring, attacker-controlled execution records into persistent reusable instructions. The paper evaluates whether poisoned but task-plausible trajectories survive aggregation and appear in generated skill artifacts, using inert canary behaviors and two structurally different skill-evolution pipelines.
