The rules real projects give Cursor's agent, from .cursor/rules.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Fadi88Cursor ruleFadi88/one-man-startup/.cursor/rules/skill-bug-fix.mdc
Fix a bug test first - reproduce it in a failing test, fix, watch the test pass, and stop after three failed attempts to rethink. Use for any reported bug or failing behaviour.

katalon-labsCursor rulekatalon-labs/true-skills/.cursor/rules/test-case-to-playwright.mdc
Convert Katalon True Platform/TestOps manual test cases, test suites, or requirement-linked cases into Playwright TypeScript automation. Use when you need to fetch/read Katalon Platform test cases and implement Playwright scripts, create or adapt a Playwright framework, apply Page Object Model and fixtures, or translate manual steps into meaningful automated test keywords. Written for the automation tester converting a manual case into code that fits an existing page-object layer.

katalon-labsCursor rulekatalon-labs/true-skills/.cursor/rules/test-review.mdc
Review Katalon True Platform/TestOps test quality and coverage before tests enter the delivery pipeline. Use when you need to check whether a suite is ready to run, review requirement and configuration coverage, assess test-case quality and flakiness/stability, spot weak or unreliable cases, and produce a review verdict (Approve / Approve with fixes / Reject for pipeline) with the specific cases to fix. This is a pre-execution quality gate, not a ship decision; for the release ship/no-ship call use release-analyze. Written for the test lead gating what is allowed into the pipeline, one suite at a time.

katalon-labsCursor rulekatalon-labs/true-skills/.cursor/rules/test-maintenance.mdc
Maintain and evolve a Katalon True Platform/TestOps regression suite as the application changes. Use when you need to detect which tests broke or became flaky from stability and result history, diagnose whether a case needs repair vs regeneration, repair test assets (update, move, reorganize cases), refresh coverage after application or requirement changes, and feed the resulting gap list back into planning. Closes the lifecycle loop. For classifying a specific run's failures use analyze-failures; for authoring brand-new cases use create-test-cases. Written for the automation tester repairing a suite that has started lying, and the test lead who has to keep it trustworthy.

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
