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.
galyarderlabsCursor rulegalyarderlabs/galyarder-framework/.cursor/rules/write-a-prd.mdc
Create a PRD through user interview, codebase exploration, and module design, then submit as a GitHub issue. Use when user wants to write a PRD, create a product requirements document, or plan a new feature.
Prorise-coolCursor ruleProrise-cool/claude-code-plugins/.cursor/rules/anti-duplication.mdc
Prevent content duplication in documentation, reports, and code. Check for existing content before creating new. Consolidate duplicates to single source of truth.
deepread-techReads credentialsCursor ruledeepread-tech/skills/.cursor/rules/deepread-setup.mdc
Get started with DeepRead OCR. Automatically obtains an API key via device authorization flow (RFC 8628), then walks through first document, structured extraction, and blueprints.
Fadi88Cursor ruleFadi88/one-man-startup/.cursor/rules/skill-verified-claims.mdc
No unconfirmed assumptions - every factual claim the founder or a user will read is confirmed by a source, test or measurement, or cut, or registered in docs/ASSUMPTIONS.md and labelled. Use when writing any document, copy, report, estimate or recommendation, and when reviewing one.
mondaycomCursor rulemondaycom/vibe/.cursor/rules/base-components.mdc
Comprehensive guide for base components in `@vibe/core` library (BaseInput, BaseList, BaseListItem, InfoText, FieldLabel). Documents their usage patterns, accessibility requirements, form integration patterns, and what consumers need to provide for optimal accessibility and UX. These components serve as foundational building blocks for complex UI components like dropdowns, text fields, and other form controls. Those components are internal, for developing components in Vibe, and are not intended to be exported from the `@vibe/core` library.
Fadi88Cursor ruleFadi88/one-man-startup/.cursor/rules/skill-single-source.mdc
Every derived figure (a total, a price, a score, a status) is computed in exactly one place and read everywhere; documents never carry hand-typed counts. Use when adding any number a user or the founder will see.
NetcrackerCursor ruleNetcracker/qubership-ai-agent-telemetry/.cursor/rules/docs-page-authoring.mdc
Trigger for the docs-page-authoring skill: load it before writing or editing a README or any other documentation page, and when a change adds or renames an option, an error, or a supported version.
IdraDevCursor ruleIdraDev/Diagrammer/.cursor/rules/diagrammer.mdc
Author Diagrammer JSON for the Diagrammer viewer. Use whenever the user asks for a mind map, concept map, flowchart, tree, dependency graph, ER diagram, or timeline. Output a single JSON document conforming to the schema below.
Fadi88Cursor ruleFadi88/one-man-startup/.cursor/rules/skill-founder-voice.mdc
How to word anything the founder reads or answers - questions, grilling rounds, approvals, decisions, summaries, reports - at the technical level saved in project.toml [owner] level (non-technical, basics or technical). Use before writing any message or document for the founder.
deepread-techReads credentialsCursor ruledeepread-tech/skills/.cursor/rules/deepread-pii-removal.mdc
DeepRead PII Removal API. Upload documents, automatically detect and redact personal information (SSN, credit cards, names, etc.), download redacted files. Endpoints, auth, and code examples.
HermeticOrmusCursor ruleHermeticOrmus/hypothesis-debugging-skills/.cursor/rules/hypothesis-debugging.mdc
Hypothesis-driven debugging protocol — reproduce, isolate, hypothesize, test, fix, document. Apply when debugging a failure. Find the root cause, not a workaround.
HermeticOrmusCursor ruleHermeticOrmus/auto-docs-skills/.cursor/rules/auto-docs.mdc
Generate and maintain project documentation from the code (README, API reference, architecture notes, setup docs). Re-runnable to keep docs in sync as the code changes.
danielvm-gitDeletes or force-pushesCursor ruledanielvm-git/bigpowers/.cursor/rules/guard-git.mdc
Block dangerous git commands (push, force push, reset --hard, clean, branch -D, checkout/restore .) and enforce Conventional Commits & Branch Protection before an AI agent runs them. Installs hook scripts for Claude Code, Cursor, Cursor CLI, and Gemini CLI; documents Google Antigravity Terminal deny lists. Use when the user wants git safety hooks, to block git push or destructive git in agents, or to mirror the same policy across AI coding tools.
KangaKodeCursor ruleKangaKode/universal-agent-bootstrap/.cursor/rules/expert-review.mdc
Full expert review protocol. 8-expert, 2-wave deliberation for comprehensive codebase and documentation review. Invoke before major milestones, after shipping feature clusters, or before staging/production deployment.
KangaKodeCursor ruleKangaKode/universal-agent-workflow-template/.cursor/rules/expert-review.mdc
Full expert review protocol. 8-expert, 2-wave deliberation for comprehensive codebase and documentation review. Invoke before major milestones, after shipping feature clusters, or before staging/production deployment.
andr-caCursor ruleandr-ca/agentharness/.cursor/rules/database-conventions.mdc
Use when designing a database schema, writing migrations, reviewing SQL queries, or choosing between relational and document models — covers naming, index strategy, migration safety, N+1 prevention, and transaction boundaries.
Fadi88Cursor ruleFadi88/one-man-startup/.cursor/rules/skill-legal-review.mdc
The legal agent's method - read the founder's playbook and the region packs, grade each checklist item GREEN, YELLOW, RED or UNSETTLED with a cited and dated source, draft documents flagged for counsel, escalate. Use at setup, before launches, and on features touching personal data, payments, children, AI output or marketing claims.
galyarderlabsCursor rulegalyarderlabs/galyarder-framework/.cursor/rules/defuddle.mdc
Extract clean markdown content from web pages using Defuddle CLI, removing clutter and navigation to save tokens. Use instead of WebFetch when the user provides a URL to read or analyze, for online documentation, articles, blog posts, or any standard web page. Do NOT use for URLs ending in .md those are already markdown, use WebFetch directly.
danielvm-gitCursor ruledanielvm-git/bigpowers/.cursor/rules/simple-english.mdc
Write or rewrite technical text with the rules of ASD-STE100 Simplified Technical English so the result is clear, unambiguous, and free of AI slop. Use for documentation, READMEs, runbooks, procedures, error messages, release notes, incident reports, and API guides. Also use when the user says \"STE\", \"Simplified Technical English\", \"ASD-STE100\", \"de-slop\", \"make this readable\", \"write for non-native readers\", or asks for docs that translate well. Enforces the 53 rules of the standard (Issue 9) with a deterministic lint gate.
RagnarPitlaCursor ruleRagnarPitla/microsoft-agent-skills-private-archive/.cursor/rules/explain-concept.mdc
Explain a Microsoft ecosystem concept to someone who is confused by it, after working out what they actually misunderstand. Use when someone asks what something is or why it behaves the way it does across Copilot Studio, Power Platform, Dataverse, Dynamics 365, Microsoft Foundry or Entra - particularly when they have already read the documentation and are still stuck.
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.
