img2threejs

img2threejs/img2threejs/CLAUDE.md

This repository is the canonical source for the img2threejs skill. Host entrypoints (~/.claude/skills/img2threejs, ~/.codex/skills/img2threejs) should be symlinks to one checkout — never independent copies, or the two hosts drift apart silently. - Preserve the code-only procedural Three.js contract; do not silently download meshes or art packs. - Keep claims honest: distinguish implemented capability from roadmap or design-only documentation. - Treat forge/ as deterministic tooling and grimoire/ as routed reference material. - Keep backward compatibility for existing sculpt specs unless a…

OpenMetadata

open-metadata/OpenMetadata/CLAUDE.md

Always-loaded guidance for every session. *Language- and path-specific rules live in .claude/rules/.md (auto-loaded when you touch matching files); procedures live in skills (loaded on invoke).* This file is the map — see the pointer index at the bottom. Read ARCHITECTURE.md for the *system map* (modules, the request/ingestion/search paths, the invariants that hold); read DEVELOPER.md for *how to build, test, and add an entity or connector* (deep dives + end-to-end checklists). Consult docs/index.md — the *knowledge index* — to *find existing…

OpenMetadata / openmetadata-ui-core-components

open-metadata/OpenMetadata/openmetadata-ui-core-components/CLAUDE.md

Shared UI component library for OpenMetadata, built on UntitledUI design system patterns with React Aria Components as the accessibility foundation. All public components must be exported from src/components/index.ts. Add new exports there when creating components. All Tailwind classes use the tw: prefix: tw:flex, tw:bg-primary, tw:text-sm, etc. This is mandatory to scope styles and prevent collisions with the main app's existing Less/Ant Design CSS. Theme colors are defined as CSS custom properties in src/styles/globals.css with light and dark mode variant

playwright-python

microsoft/playwright-python/CLAUDE.md

Guidance for Claude when working in this repository. Python bindings for Playwright. The Python client talks JSON over a pipe to the Node-based driver bundled in playwright/driver/. The pipe protocol is defined upstream in packages/protocol/src/protocol.yml. CONTRIBUTING.md has the full sequence. The short version (needs Node.js and npm for the driver build): If the system lacks python3-venv, uv venv env is an acceptable substitute (then uv pip install --python env/bin/python --upgrade pip). When changing public API, edit impl/, then run ./scripts/updateapi.sh.…

walkinglabs/learn-harness-engineering/CLAUDE.md

Learn Harness Engineering is a project-based course on building reliable coding environments for AI agents. The repo contains a VitePress documentation site plus hands-on project code. The course revolves around an Electron knowledge-base desktop app that evolves across the projects: - Main process (src/main/): Window management, IPC handlers, service initialization - Preload (src/preload/): contextBridge exposing typed API to renderer - Renderer (src/renderer/): React UI with document list, Q&A panel, status bar - Services (src/services/): DocumentService, IndexingService, QaService, PersistenceService - Shared…

CoplayDev/unity-mcp/CLAUDE.md

MCP for Unity is a bridge that lets AI assistants (Claude, Cursor, Windsurf, etc.) control the Unity Editor through the Model Context Protocol (MCP). It enables AI-driven game development workflows - creating GameObjects, editing scripts, managing assets, running tests, and more. Two codebases, one system: - Server/ - Python MCP server using FastMCP - MCPForUnity/ - Unity C# Editor package The Python server has three distinct layers. These are not auto-generated from each other: MCP tools call Unity via WebSocket…

EverOS

EverMind-AI/EverOS/CLAUDE.md

This is a Python framework for md-first memory extraction (lightweight; single-user or small-team). DDD 5 layers + cross-cutting: Dependency rule: entrypoints → service → memory → infra. Single-direction, enforced by import-linter. Detailed: docs/architecture.md. Contributor engineering reference — build, test, CI gates, branch & commit conventions: docs/engineering.md. main is the default and protected branch. Create scoped branches from main (feat/, fix/, docs/, ci/, chore/, refactor/) and open pull requests back to main after the required checks pass. See .claude/skills/new-branch/SKILL.md for the…

System prompts extracted via script from the Claude Code npm package's compiled JavaScript source. Maintained by Piebald AI, not by Anthropic. See the Extraction section in README.md for details on the extraction method. Claude Code is Anthropic's CLI tool for agentic coding. It is distributed as a compiled npm package (@anthropic-ai/claude-code). Source code is not publicly available. The anthropics/claude-code GitHub repository contains issues and releases only.

agent-orchestrator

Untrivial-ai/agent-orchestrator/CLAUDE.md

Read and follow AGENTS.md for repository layout, commands, coding conventions, and hard rules. All app state, the daemon's data dir, running.json, worktrees, and the Electron supervisor's userData (Chromium cache, cookies, local/session storage, crash dumps), must resolve under ~/.ao (overridable via AODATADIR/AORUNFILE). Never write to or read from ~/Library/Application Support or any other OS-default app-data location. frontend/src/main.ts pins Electron's userData to ~/.ao/electron; do not remove that override. See the hard rule in AGENTS.md. Always read DESIGN.md before making any visual or…

CLAUDE.md vs AGENTS.md

About CLAUDE.md

What is CLAUDE.md?

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.

Where does it go?

At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.

What should it contain?

Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.

CLAUDE.md or AGENTS.md?

Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
