Add complete .cursor/ directory with rules, agents, skills, commands, and MCP config adapted for Cursor's format. This makes ecc-universal a truly cross-IDE package supporting Claude Code, Cursor, and OpenCode. - 27 rule files with YAML frontmatter (description, globs, alwaysApply) - 13 agent files with full model IDs and readonly flags - 30 skill directories (identical Agent Skills standard, no translation) - 31 command files (5 multi-* stubbed for missing codeagent-wrapper) - MCP config with Cursor env interpolation syntax - README.md and MIGRATION.md documentation - install.sh --target cursor flag for project-scoped installation - package.json updated with .cursor/ in files and cursor keywords

Migrating from Claude Code to Cursor
This guide maps Claude Code concepts to their Cursor equivalents.
Concept Mapping
| Claude Code | Cursor | Notes |
|---|---|---|
~/.claude/rules/ |
.cursor/rules/ |
Project-scoped; YAML frontmatter with description, globs, alwaysApply |
~/.claude/agents/ |
.cursor/agents/ |
model: opus → model: anthropic/claude-opus-4-5; tools → readonly |
~/.claude/skills/ |
.cursor/skills/ |
Identical Agent Skills standard (SKILL.md) |
~/.claude/commands/ |
.cursor/commands/ |
Compatible markdown format |
~/.claude.json mcpServers |
.cursor/mcp.json |
Uses ${env:VAR_NAME} interpolation syntax |
| Hooks (PreToolUse/PostToolUse/Stop) | No equivalent | Use linters, formatters, pre-commit hooks, CI/CD |
| Contexts | Rules with alwaysApply: false |
Manually activated via @ mentions |
model: opus |
model: anthropic/claude-opus-4-5 |
Full model ID required |
model: sonnet |
model: anthropic/claude-sonnet-4-5 |
Full model ID required |
tools: ["Read", "Grep"] |
readonly: true |
Read-only tools mapped to readonly flag |
tools: ["Read", "Write", "Bash"] |
readonly: false |
Write tools mapped to full access |
Feature Parity Matrix
| Feature | Claude Code | Cursor | Status |
|---|---|---|---|
| Rules | Global + Project | Project only | Available |
| Agents | Full tool control | readonly flag | Available |
| Skills | Agent Skills standard | Agent Skills standard | Identical |
| Commands | Slash commands | Slash commands | Available |
| MCP Servers | Native support | Native support | Available |
| Hooks | PreToolUse/PostToolUse/Stop | Not available | Use alternatives |
| Contexts | Context files | Rules (alwaysApply: false) | Partial |
| Multi-model orchestration | codeagent-wrapper | Not available | Not available |
| Global config | ~/.claude/ | Project .cursor/ only | Different scope |
Key Differences
Rules
- Claude Code: Rules stored globally in
~/.claude/rules/with subdirectories - Cursor: Rules stored in project
.cursor/rules/with YAML frontmatter for metadata - Translation: Subdirectory paths flattened with hyphens (e.g.,
common/security.md→common-security.md)
Agents
- Claude Code: Specify individual tools via
tools: [...]array - Cursor: Binary
readonly: true/falseflag - Translation: Read-only tools (Read, Grep, Glob) →
readonly: true; any write tool →readonly: false
Model IDs
- Claude Code: Short names (
opus,sonnet,haiku) - Cursor: Full Anthropic model IDs (
anthropic/claude-opus-4-5,anthropic/claude-sonnet-4-5)
Hooks → Alternatives
Claude Code hooks have no direct equivalent in Cursor. Alternatives:
- Formatting on save: Configure Cursor's format-on-save with Prettier, Black, gofmt
- Linting: Use Cursor's built-in linter integration (ESLint, Ruff, golangci-lint)
- Pre-commit: Use
huskyorpre-commitfor git hooks - CI/CD: Move stop-hook checks to GitHub Actions or similar
MCP Configuration
- Claude Code: Environment values use placeholder strings (e.g.,
"YOUR_GITHUB_PAT_HERE") - Cursor: Environment values use interpolation syntax (e.g.,
"${env:GITHUB_PERSONAL_ACCESS_TOKEN}")
Tips for Migrating
- Start with rules: Install common + your language-specific rules first
- Add agents gradually: Start with planner and code-reviewer, add others as needed
- Skills are plug-and-play: The skills/ directory works identically in both tools
- Set up MCP: Copy mcp.json and configure your environment variables
- Replace hooks with CI: Set up pre-commit hooks and CI checks for what you lose from Claude Code hooks
