It is also happy to announce \"done\" without running the tests, rewrite a whole file to change one line, and install a package that doesn't exist. The Coding Agent Rules Pack gives it house rules: ready-to-drop-in instruction files that tell it to run your real commands and show the results before claiming done, keep diffs small, check that every package exists before installing it, keep secrets out of code and commits, follow your code style and git habits, and ask instead of guessing when something is hard to undo.\u003c\/p\u003e\n\u003cp\u003eThe files are organized by tool, in each tool's own format: \u003ccode\u003e.cursor\/rules\/*.mdc\u003c\/code\u003e with proper frontmatter for Cursor, \u003ccode\u003eCLAUDE.md\u003c\/code\u003e plus \u003ccode\u003e.claude\/rules\/\u003c\/code\u003e for Claude Code, \u003ccode\u003eAGENTS.md\u003c\/code\u003e for OpenAI Codex and other AGENTS.md-aware agents, and \u003ccode\u003e.github\/copilot-instructions.md\u003c\/code\u003e for GitHub Copilot. Pick your stack, copy one folder, fill in a short project-context template, and you're set up. The 18-page PDF guide explains how each tool loads rules, how to install, customize, and combine them, the mistakes that make rules fail silently, and ends with a one-page cheat sheet. Every file path and format was checked against each tool's official docs in October 2026, and the guide lists the sources so you can re-check them when the tools change.\u003c\/p\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal base rules:\u003c\/strong\u003e read before editing, ask when unsure, small diffs, dependency and package-hallucination checks, no secrets, code style, verify before \"done\", git hygiene, and a standard end-of-task summary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 stack variants\u003c\/strong\u003e with real commands and stack-specific traps: TypeScript + Next.js, React + Vite, Node.js + Express API, Python + FastAPI, Python data and notebooks, Go service, Rust, React Native (Expo or bare)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6 task-mode add-ons:\u003c\/strong\u003e bugfix, refactor, tests-first, security review, docs, and always-on \"don't touch\" boundaries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill-in Project Context template:\u003c\/strong\u003e commands, layout, conventions, environment, owners, gotchas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCursor set:\u003c\/strong\u003e \u003ccode\u003e.cursor\/rules\/*.mdc\u003c\/code\u003e files with \u003ccode\u003ealwaysApply\u003c\/code\u003e \/ \u003ccode\u003edescription\u003c\/code\u003e frontmatter, plus 8 stack rules\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClaude Code set:\u003c\/strong\u003e \u003ccode\u003eCLAUDE.md\u003c\/code\u003e, \u003ccode\u003e.claude\/rules\/\u003c\/code\u003e files, and mode files to @-mention\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAGENTS.md set:\u003c\/strong\u003e ready-assembled \u003ccode\u003eAGENTS.md\u003c\/code\u003e for each stack plus a generic one\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGitHub Copilot set:\u003c\/strong\u003e \u003ccode\u003e.github\/copilot-instructions.md\u003c\/code\u003e for each stack, a path-specific \u003ccode\u003etests.instructions.md\u003c\/code\u003e, and the task modes as \u003ccode\u003e.prompt.md\u003c\/code\u003e files\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-neutral source modules\u003c\/strong\u003e so you can maintain one set of rules for several tools\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e18-page PDF guide\u003c\/strong\u003e with install commands, customization, combining files, common mistakes, troubleshooting, a one-page cheat sheet, and the official doc sources checked\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e83 files in one ZIP\u003c\/strong\u003e, plain Markdown, edit anything\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWritten for\u003c\/strong\u003e Cursor, Claude Code, OpenAI Codex, and GitHub Copilot as documented in October 2026.
