Hierarchical Repair Strategy for Runtime Failures
Scenario: During runtime, if a procedural step fails (e.g., due to data irregularities or unexpected tool behavior), CangLing-KnowFlow activates its hierarchical repair strategy.
Action: First, it queries the Evolutionary Memory Module for knowledge-driven repair actions based on similar past failures. If a solution is found, it's applied immediately (Tier 1). If not, the problem is escalated to the LLM for creative repair, generating a novel plan (Tier 2). The repair plan is translated into workflow graph manipulations (node replacement, insertion, parameter modification).
Outcome: This structured approach leverages past experience for quick, reliable fixes and allows for novel problem-solving when needed, ensuring robustness in unpredictable scenarios.
CangLing-KnowFlow's performance was rigorously evaluated against existing agent paradigms and a novel benchmark.

Cross-Benchmark Generalization Performance (ThinkGeo)
20.3% Task Success Rate (vs. 9.0% of ReAct baseline)The framework achieved a Task Success Rate of 20.3% on the ThinkGeo benchmark, demonstrating a performance doubling against baselines (9.0% for ReAct) in unseen environments. This validates its robustness and adaptability beyond its native environment.

Illustrative Comparison: React vs. Reflexion vs. KnowFlow (Change Detection Task)
Scenario: Consider a remote sensing task involving building change detection. This requires a multi-step workflow, including critical data preprocessing (coregistration) to ensure accuracy.
Action: ReAct: Exhibits 'planning myopia,' overlooking the crucial coregistration step, leading to improperly prepared data and scientifically unsound results.
Reflexion: Demonstrates marginal improvement by attempting local parameter changes or retries upon failure, but fails to diagnose the fundamental missing coregistration step.
CangLing-KnowFlow: Queries its PKB, retrieves an expert-validated workflow template that explicitly includes the mandatory coregistration step, ensuring all actions are performed in the correct sequence.
Outcome: CangLing-KnowFlow replaces reactive, error-prone improvisation with proactive, reliable, and grounded execution, guaranteeing integrity and accuracy. It consistently performs the correct sequence with correct dependencies, unlike the other agents.
