nearcore

Review a Rust pull request against the nearcore engineering rubric — correctness, production safety, performance, Rust-specific concerns, security, and comment quality. Use when asked to review a PR, do a code review of a branch's changes, or check a diff before merge. This is the same rubric CI runs on @claude review.

Create a PR from staged changes with auto-generated branch, title, and description. Use this skill whenever the user wants to create a pull request, ship changes, open a PR, send code for review, or push staged work to GitHub — even if they don't explicitly say "PR".

Migrate a pytest integration test to the test-loop framework. Use when converting a pytest from pytest/tests/ to a deterministic test-loop test.
