## Summary  
MEGA (Meta Evaluation‑Grounded Adaptation) proposes a self‑evolving infrastructure that continuously improves coding agents by turning each optimization cycle into a durable asset of transferable wisdom. The system integrates meta‑evaluation, compositional reasoning, and multi‑agent collaboration so that the knowledge accumulated during one run directly guides the next round of optimization. By closing the loop between evidence and both curation strategies and optimization trajectories, MEGA makes optimizing agents and evolving their guiding knowledge a single iterative process. This moves beyond static agent tuning toward an adaptive, self‑improving pipeline.

## Key Contributions  
- **Self‑evolving infrastructure**: MEGA couples knowledge accumulation with meta‑evaluation, enabling the system to improve both its optimization strategies and the accumulated wisdom simultaneously.  
- **Wisdom Graph as a compositional reasoning engine**: The graph decomposes agent sessions into atomic PCR (Primary‑Context‑Resultant) units, supporting deductive, abductive, and inductive reasoning that extends implicit relations beyond simple embedding similarity.  
- **Multi‑agent collaborative optimization with causal attribution**: Layer 3 orchestrates heterogeneous agents (code nodes, LLM calls, tool users), isolates improvement effects to specific strategy changes via controlled A/B testing, and feeds the evidence back into the system.

## Methodology  
The authors structured MEGA as a three‑layer pipeline. **Layer 1** extracts reusable wisdom from agent sessions through behavioral‑pattern clustering and empirical A/B validation, converting each process into a durable asset. **Layer 2** decomposes these assets into atomic PCR units within a typed Wisdom Graph; it then performs deductive, abductive, and inductive reasoning to expand implicit relations and assembles context‑specific execution plans via compositional retrieval that surfaces bridging knowledge unavailable through embedding similarity alone. **Layer 3** runs multi‑agent workflows (code nodes, LLM invocations, tool‑using agents), attributes observed improvements to particular strategy modifications using controlled evaluation, and uses the resulting evidence to self‑evolve both curation strategies and optimization trajectories.

## Results  
Experiments on standard code‑generation benchmarks demonstrate that MEGA reduces the number of optimization cycles required for convergence by up to 40 % while increasing final code correctness scores. Moreover, the Wisdom Graph’s compositional reasoning improves the accuracy of generated execution plans, achieving a measurable rise in task success rates compared with baseline embedding‑based retrieval methods.

## Significance  
MEGA addresses a longstanding bottleneck: static agent optimization that discards accumulated knowledge and isolated learning that cannot reason over its own output. By making the evolution of both strategy and wisdom an inseparable process, MEGA paves the way for scalable, adaptive AI coding agents that continuously improve without manual intervention.
