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.

tounsilsCursor ruletounsils/claude-code-skills/.cursor/rules/root-cause.mdc
Debug by reproducing first, isolating the mechanism, then fixing the cause rather than the symptom, and keeping the reproduction as a regression test. Use when asked to debug this, fix this bug, find out why something happens, investigate a failure, or work out what is going wrong, and when a test fails intermittently or flakily, behavior differs between environments, or someone proposes raising a timeout, adding a retry, or skipping a test to make a problem go away.

MANVENDRA-githubCursor ruleMANVENDRA-github/agentry/.cursor/rules/tdd-workflow.mdc
Test-first development with explicit red-green-refactor loops. Invoke when implementing a feature with well-defined inputs and outputs, fixing a reproducible bug, or refactoring code that already has tests. Skip for exploratory spikes, UI-heavy work, or one-off scripts where test overhead exceeds value.

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.
