🧪 eliminate sys.path.insert hacks — migrate to package-relative imports

[sheepdestroyer]

🎯 What: This PR removes vestigial sys.path.insert hacks from 9 scripts in the scripts/ directory, migrating them to use standard package-relative imports. This cleanup follows the addition of init.py files in PR #264/#265 and ensures a cleaner, more robust import structure. It also adds a missing init.py to the router/ directory and updates router/main.py to use package-aware imports.

Fixes #266

Warning

Review limit reached

@sheepdestroyer, you've reached your PR review limit, so we couldn't start this review.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change removes startup sys.path mutations from scripts, updates router import resolution for package execution, and sets benchmark environment variables explicitly.

Changes

Package import cleanup

Layer / File(s)	Summary
Router package import setup router/main.py, scripts/benchmark_tokens.py	router.main uses a relative circuit-breaker import, and token benchmarking no longer adjusts sys.path while setting its router environment variables.
Script package resolution scripts/benchmark_classifier.py, scripts/classify_direct.py, scripts/reclassify_all.py, scripts/retry_errors.py, scripts/verification/*	Classifier and verification scripts remove runtime sys.path modifications and continue using package-based imports.

Code Review

This pull request cleans up the codebase by removing dynamic sys.path modifications across several benchmark and verification scripts. It also updates the import of circuit_breaker in router/main.py. Feedback suggests using an explicit relative import instead of an absolute import in router/main.py to align with PEP 8 standards for package-relative imports.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Closing in favor of a fresh PR with all review fixes applied: reverted Gemini false-positive relative import (was breaking CI) and added ImportError fallbacks to all chat_helpers imports. See #271.
