📝 Walkthrough

Walkthrough

The changes add Python 3.13 support to the project by updating the CI workflow to test against Python 3.13, fixing a deprecation warning in asyncio usage, and updating project configuration metadata to reflect the new supported version.

Changes

Cohort / File(s)	Summary
CI/Workflow Configuration .github/workflows/ci.yml	Extended Python test matrix from [3.10, 3.11, 3.12] to [3.10, 3.11, 3.12, 3.13]
Runtime Improvements cortex/parallel_llm.py	Replaced asyncio.get_event_loop() with asyncio.get_running_loop() to align with modern asyncio practices and avoid deprecation warnings
Project Configuration pyproject.toml	Added "Programming Language :: Python :: 3.13" classifier and extended Black's target-version to include "py313"

Poem

🐰 Hopping into Python 3.13's embrace,
Where async loops run at a faster pace,
CI tests now span the newest version,
Black formats code with fresh conversion,
Forward-ready, no warnings to trace! ✨

Check name	Status	Explanation	Resolution
Linked Issues check	❓ Inconclusive	The PR addresses key requirements from #272: adds Python 3.13 to CI matrix, fixes asyncio deprecation, and updates project classifiers. However, performance benchmarking and comprehensive dependency validation testing are not evident.	Clarify whether dependency compatibility testing (LangChain, Rich, Typer) was performed and if performance benchmarks comparing Python 3.11 vs 3.13 were conducted, as required by issue #272.

Title check	✅ Passed	The title accurately summarizes the main change: adding Python 3.13 support across the project configuration and workflows.
Description check	✅ Passed	The description covers the required sections with issue reference and summary, though some checklist items remain incomplete (MVP label and 'Cortex -h' update).
Out of Scope Changes check	✅ Passed	All changes directly support Python 3.13 compatibility: CI matrix extension, asyncio modernization, and version classifiers are all in-scope.

Code Review

This pull request correctly adds support for Python 3.13 by updating the asyncio call in parallel_llm.py and modifying pyproject.toml. The change from asyncio.get_event_loop() to asyncio.get_running_loop() is appropriate for Python 3.10+ and necessary for future compatibility. The updates to the project classifiers and black configuration are also correct.

I have one suggestion to further modernize the asynchronous code by using asyncio.to_thread, which simplifies running synchronous functions in a separate thread. Overall, this is a good and necessary update for the project.
