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.

Evaluate this agent's failure through the lens of control-signal dilution. Explain how the agent's exec

What three forms of accumulated data lengthen an agent's interaction trace and bury its initial plan during control-signal dilution?

Explain why control-signal dilution is categorized as an operational execution failure mode rather than an initial planning defect. In your response, contrast the state of the agent's guiding control signals at initialization with how runtime trace dynamics alter their influence over time.

In long-horizon agents, execution tokens accumulate in an append-only context from commands, observations, and intermediate repairs.

According to the definition of control-signal dilution, which two guiding elements experience a weakening influence over time?

Match each behavioral symptom of control-signal dilution to the specific behavior exhibited by the agent.

Identify the operational execution failure mode exhibited by the agent and describe the context dynamics that triggered its unproductive repetition and premature termination.

What attention-level mechanism causes an agent to lose the guidance of its initial instructions as commands, observations, and repairs accumulate in an append-only trace?

External runtime harnesses mitigate control-signal dilution by refreshing phase-relevant control information upon state entry.

Which intervention is employed by external runtime harnesses to directly counteract control-signal dilution when an autonomous agent transitions between phases?

In long-horizon autonomous agents, the guiding influence of the plan strengthens as execution tokens accumulate.

According to the control-signal dilution hypothesis, which two guiding elements experience a weakening influence as execution tokens accumulate?

External runtime harnesses mitigate control-signal dilution in part by externalizing ___ state rather than keeping it inside the execution trace.

Place the operational stages of control-signal dilution in chronological order from earliest to latest.
