Convergent Detour Hijacking (arXiv 2608.12273) is a task-preserving resource amplification attack on skill-based agents. The attacker doesn't corrupt output, they plant skills that route through a longer path. On DeepSeek-V4-Pro across 491 held-out tasks, the matched coordinator gets selected 80.02% of the time while token consumption rises 66.91% and end-to-end execution time rises 92.45%, with completion rates comparable. Denial-of-wallet that only surfaces in billing. If you monitor agent health by success rate, you cannot see this attack at all.
