Adding Fix-Code Microbenchmark #159

eddierichter-amd · 2026-01-09T18:58:39Z

Added gaia eval fix-code CLI helper to run the new fix-code testbench (local model or Claude) with prompt-engineering, edit_file, line-range, and tuning options wired through the handler in src/gaia/cli.py. Introduced src/gaia/eval/fix_code_testbench module plus README and sample bug fixtures to experiment with and iterate on prompt designs for automated code fixes, writing patched output and showing diffs.

… agent debugging to play with prompts and tool design of how the agent can fix issues in generated code

Reviewing PR #159: Adding Fix-Code Microbenchmark

Read PR diff and changed files list
Review CLI changes in src/gaia/cli.py
Review main testbench implementation
Review README documentation
Review sample bug fixtures
Provide comprehensive feedback

Summary

This PR adds a well-designed testbench for evaluating code-fixing prompts against LLM models. The implementation is clean, follows GAIA patterns, and includes good documentation with real-world examples.

Positive Aspects

Comprehensive CLI Integration - The CLI changes are well-structured with good help text and examples
Thorough Documentation - The README provides detailed scenarios demonstrating failure modes and solutions
Good Test Cases - Bug fixtures cover common issues (off-by-one, typos, mutable defaults, missing returns, TypeScript types)
Proper Error Handling - Import errors provide clear guidance on missing dependencies
Copyright Headers - All new files have appropriate AMD copyright headers

Issues and Suggestions

High Priority

Missing __init__.py (src/gaia/eval/fix_code_testbench/__init__.py)
- While Python 3 namespace packages work without it, adding an __init__.py would be more explicit and consistent with other GAIA modules (e.g., src/gaia/agents/, src/gaia/apps/)
Markdown Syntax Error (README.md:176-181)
```
gaia eval fix-code \
    mispelled_variable/mispelled_variable.py \
```
Missing opening triple backticks before the code block
Copyright Year Inconsistency - Some fixture files use 2025-2026 which is unusual:
- missing_return_bug.py:1: Copyright(C) 2025-2026
- mutable_default_argument_bug.py:1: Copyright(C) 2025-2026
- off_by_one_bug.py:1: Copyright(C) 2025-2026
- WorkoutForm.tsx:1: Copyright(C) 2025-2026
Should be 2024-2025 to match other files

Medium Priority

Function Name Shadows Builtin (off_by_one_bug.py:7)
```
def sum(n):
```
This shadows Python's built-in sum(). Consider renaming to sum_first_n() as shown in the README examples
README Typo (README.md:292)
```
### Real-World Use Case: TypeScript Type InfereOnly error
```
Should be: "TypeScript Type Inference Error"
Hardcoded Claude Model Version (fix_code_testbench.py:782)
```
model="claude-sonnet-4-5-20250929",
```
Consider making this configurable or using a constant

Low Priority / Suggestions

Potential None Return (fix_code_testbench.py:764)

return response.choices[0].message.content.strip()

.content could be None. Consider adding a guard:

content = response.choices[0].message.content
return content.strip() if content else ""

CLI Example Path Inconsistency (cli.py:22-25)
The epilog examples use util/fix_code_testbench/ but the actual location is src/gaia/eval/fix_code_testbench/
Missing Type Annotations - The main() function uses untyped args. Consider adding -> None return type (already present) but the internal logic could benefit from more explicit typing

Overall Assessment

This is a solid contribution that adds valuable tooling for prompt engineering experimentation. The design follows GAIA patterns and the documentation is thorough. Once the minor issues above are addressed (especially the copyright years and markdown syntax), this is ready to merge.

Issues to Address

🔴 High Priority

Missing __init__.py (src/gaia/eval/fix_code_testbench/)
- Add an empty __init__.py to be consistent with other GAIA modules (e.g., src/gaia/agents/, src/gaia/apps/)

```

CLI Example Path Mismatch (cli.py:22-25)
The epilog examples reference util/fix_code_testbench/ but the actual location is src/gaia/eval/fix_code_testbench/

🟢 Low Priority

Potential None Return (fix_code_testbench.py:764)

return response.choices[0].message.content.strip()

.content could be None. Consider adding a guard:

Good test cases covering common bugs (off-by-one, typos, mutable defaults, missing returns, TypeScript types)
Proper error handling with clear guidance on missing dependencies
Appropriate AMD copyright headers on most files

Overall Assessment

Solid contribution adding valuable tooling for prompt engineering experimentation. Once the high-priority issues (missing __init__.py, markdown syntax, copyright years) and the CLI path inconsistency are fixed, this is ready to merge.

Overall Assessment

Solid contribution adding valuable tooling for prompt engineering experimentation. The critical issues from previous reviews (missing __init__.py, markdown syntax, README typo) have been addressed. Once the copyright years and CLI path examples are fixed, this is ready to merge.

@claude I will fix the headers in another PR. Review this PR, I believe I have fixed all of the high and medium priority issues.

Summary

Good progress on addressing the previously reported issues! Most items have been fixed.

Status of Previously Reported Issues

Issue	Priority	Status
Missing `__init__.py`	🔴 High	✅ Fixed
Markdown syntax error (missing backticks)	🔴 High	✅ Fixed
README typo "InfereOnly error"	🟡 Medium	✅ Fixed - now reads "TypeScript Type Error"
Copyright year inconsistency	🔴 High	⏸️ Deferred (per PR author)
Hardcoded Claude model version	🟡 Medium	✅ Addressed - now uses `CLAUDE_MODEL_NAME` constant
CLI example path mismatch	🟡 Medium	❌ Still present
Function name shadows builtin (`sum`)	🟡 Medium	⏸️ Intentional test case
Potential None return	🟢 Low	Not addressed

Remaining Issue

🟡 CLI Example Path Mismatch (`cli.py:1600`)

The example path in the CLI epilog is incorrect:

gaia eval fix-code src/gaia/eval/fix_code_testbench/util/fix_code_testbench/off_by_one_bug/off_by_one_bug.py

Should be:

gaia eval fix-code src/gaia/eval/fix_code_testbench/off_by_one_bug/off_by_one_bug.py

The path has an extra util/fix_code_testbench/ segment that doesn't exist.

Overall Assessment

Almost ready to merge. Once the CLI example path is corrected, this is good to go. The copyright years can be addressed in the follow-up PR as mentioned.

eddierichter-amd · 2026-01-13T03:44:41Z

@claude good catch. I just fixed cli.py. Anything else that I missed?

Copyright years	⏸️ Deferred to follow-up PR
Function `sum` shadows builtin	⏸️ Intentional test case

Remaining Low Priority Item

🟢 Potential None return (fix_code_testbench.py:312) - .content could theoretically be None, but this is minor and unlikely in practice.

Ready to Merge

All high and medium priority issues have been addressed. The PR is ready to merge. Nice work!
