PR Review Summary

Prek Checks

✅ All checks pass — ruff check and ruff format both passed with no issues.

Mypy

⚠️ 60 no-untyped-def errors in tests/test_languages/test_treesitter_utils.py — all are missing return type annotations on test methods. This is a pre-existing pattern across the entire file (same style on main branch), not introduced by this PR. No action needed.

Code Review

No critical issues found. Summary of changes:

packages/codeflash/scripts/postinstall.js — Changes install strategy to prefer GitHub clone over PyPI:

• Adds hasGit() helper to check for git availability
• Modifies installCodeflash() to first try git+https://github.com/codeflash-ai/codeflash.git, falling back to PyPI
• Removes old local-source fallback (tried to install from local pyproject.toml)
• The hardcoded GitHub URL avoids injection risks. Shell quoting for uvBin is consistent with existing patterns.

tests/test_languages/test_treesitter_utils.py — Adds 10 new tests for export const arrow function patterns in TypeScript:

• All 10 new tests pass ✅ (53/53 total)
• Tests cover: basic export const, optional params, generics, export detection, default exports, multiple exports, implicit return, async, and non-exported const patterns
• All tested API methods (is_function_exported, find_functions, has_return_statement) verified to exist on TreeSitterAnalyzer

Test Coverage

File	Status	Notes
packages/codeflash/scripts/postinstall.js	N/A	JavaScript file — not covered by Python test suite
tests/test_languages/test_treesitter_utils.py	✅ Test file	10 new tests added, all passing

No production Python files were modified in this PR, so there is no Python coverage delta to measure. The new tests exercise codeflash/languages/treesitter_utils.py (TreeSitterAnalyzer, FunctionNode, ImportInfo) which improves coverage of that module.
