Control-Signal Dilution
Control-signal dilution is an operational execution failure mode and design hypothesis in long-horizon autonomous agents where the guiding influence of a compact plan and its completion criteria weakens as execution tokens accumulate. As an agent generates a long append-only trace of commands, observations, and intermediate repairs, the high-level plan tokens receive diminishing attention relative to the surrounding trace. This dilution causes the agent to deviate from its plan, repeat unproductive steps, or terminate prematurely before satisfying task obligations. External runtime harnesses mitigate this failure by externalizing procedural state, refreshing phase-relevant control contexts upon state entry, and verifying progress before transitions.

A software maintenance agent is configured to resolve a complex repository issue using an initial compact plan and defined completion contracts. Over hours of operation, the agent generates numerous tool calls, parses voluminous environment feedback, and attempts multiple local fixes. Eventually, the agent begins cycling through redundant status queries and halts before completing the repair.
