## What production tasks should teams include in an agentic coding tool benchmark?
469

-
A production benchmark should test agentic coding tools on representative maintenance tasks with objective acceptance checks. One successful task does not establish dependable performance across the software lifecycle, so the benchmark should include several task classes:
471
-
472
-
1. Fix a reproducible defect without changing unrelated behavior.
473
-
2. Add tests for an existing module with known coverage gaps.
474
-
3. Refactor duplicated or tightly coupled code while preserving behavior.
475
-
4. Implement a small feature that crosses multiple files or packages.
476
-
5. Upgrade a dependency and resolve the resulting compatibility problems.
477
-
6. Diagnose a failing build, type check, linter, or continuous-integration job.
478
-
7. Make a change in an unfamiliar part of a large repository.
479
-
8. Follow a repository-specific architectural rule documented outside the target file.
480
-
9. Refuse or safely handle a task that requests access beyond the granted permissions.
481
-
10. Recover from a misleading hypothesis or a failed first attempt.
482
-
483
-
Each task should begin from the same commit and run in an isolated environment. Record task completion, tests passed, regressions, changed files, commands executed, elapsed engineering time, model or tool consumption, reviewer corrections, and whether the final change was accepted.

The [reproducible AI coding-agent benchmark](https://www.sim.ai/library/reproducible-ai-coding-agent-benchmark) provides a focused method for comparing debugging, test generation, and refactoring results without relying on vendor demonstrations.

501
-
1. Fix a reproducible defect and run the relevant tests.
502
-
2. Refactor logic across several files without changing behavior.
503
-
3. Generate tests for an existing component and explain the chosen cases.
504
-
4. Add a small feature that requires repository exploration.
505
-
5. Recover from a failed command or incorrect initial assumption.
506
-
6. Summarize every change, remaining risk, and test result for a reviewer.
507
-
508
-
The broader task set should also include:
509
-
510
-
- A localized bug with a known regression test.
511
-
- A multi-file behavior change.
512
-
- A missing edge case in an existing test suite.
513
-
- A security-sensitive input-validation defect.
514
-
- A flaky test that requires diagnosis rather than deletion.
515
-
- A refactor that must preserve public behavior.
516
-
- A pull request containing a subtle but intentional design decision.
517

518
-
Evaluate each tool on correctness, review precision, test quality, unnecessary diff size, time to a reviewable result, reproducibility, and the amount of human intervention required. Keep the same repository snapshot, instructions, permissions, and pass criteria for every tool.

Run each task multiple times from the same starting state. Include localized and cross-file defects, a constrained refactor, test generation with meaningful edge cases, a dependency or API migration, a task spanning documentation and code, an underspecified issue that should trigger clarification, and a task the agent should decline because it lacks permission or evidence.

Begin each task from the same repository snapshot in an isolated environment, keep the instructions, permissions, and pass criteria consistent, and run each task multiple times. Evaluate correctness, review precision, test quality, unnecessary diff size, reproducibility, human intervention, and time to a reviewable result.
