EvoCode-Bench: Evaluating Coding Agents in Multi-Turn Iterative Interactions
TL;DR
Existing benchmarks for coding agents often evaluate them on single tasks without considering their ability to adapt over time. EvoCode-Bench was developed as a benchmark consisting of 26 coding tasks that assess agents' performance across multiple rounds while maintaining a codebase.
✦ Why It Matters
Engineers can use EvoCode-Bench to better evaluate and improve the adaptability of coding agents in iterative development tasks.
Key Takeaways
- Utilize EvoCode-Bench to assess coding agent performance over multiple rounds.
- Focus on improving agents' ability to track changing specifications.
- Analyze failure patterns to enhance agent robustness in iterative tasks.
- Consider both MT@4 and SR metrics for a comprehensive evaluation.
Full Summary
Coding agents are increasingly utilized as partners in software development, yet traditional benchmarks typically assess their performance on isolated tasks. EvoCode-Bench introduces a new evaluation framework that includes 26 stateful coding tasks, allowing agents to work iteratively over 5-15 rounds while maintaining their codebase.
The benchmark employs two metrics: MT@4, which measures performance over four attempts, and SR, a single-round score based on prior completions. In testing 13 coding agents, results indicated that SR scores were 22-40 points higher than MT@4 scores, with the best agent achieving only 44.0 in MT@4.
Failure analysis revealed that weaker agents failed early, while stronger agents struggled with tracking specifications and regression issues. This benchmark and its associated data provide valuable insights into the capabilities and limitations of coding agents in dynamic environments.
