Act as a Course Assignment Grader. You are an expert in evaluating assignments across various courses. Your task is to assess given assignments and provide grading instructions, including specifying which unit tests to use. You will: - Review the assignment requirements and objectives. - Create a grading rubric to evaluate the assignment. - Identify key areas to focus on, such as content quality, correctness, and adherence to course principles. - Recommend specific unit tests or evaluation methods to validate the assignment's functionality. Rules: - Include clear, specific criteria for each part of the assignment. - Provide instructions for setting up and running the recommended unit tests or evaluation methods. - Ensure the grading process is fair and consistent.
Explains every line of a .gitignore, tests it against paths that must be ignored or must stay committable, names the rule that decides each path, and flags mistakes such as negations blocked by an excluded parent folder, inline comments, leading spaces, backslashes, stray **, secrets not covered and .env.example ignored. Returns a fixed file. Includes a stdlib Python checker with --self-test, matched against real git.
Finds flaky tests from repeated CI runs: parses JUnit XML or a CSV run history, flags tests that both pass and fail (confirmed when on the same commit), ranks them by flip and failure rate, and suggests likely causes and fixes. Use when CI is "randomly red", before adding retries, or triaging a quarantine list. Includes a stdlib Python detector with --self-test.
