AgentExecutor reaches 94% code coverage

AgentExecutor reached 94% code coverage on Stack Overflow snippets and 90% on open-source project code by having multiple agents reconstruct missing execution context. The ASE 2026 preprint reports gains of 19.9 and 13.8 percentage points over Treefix, alongside reductions of up to 80.3% in execution time and 56.6% in cost. Builders comparing coding-agent harnesses whose task setup can swing both solves and spend should file this as evidence that environment construction and feedback loops can matter as much as the model selected for debugging.
