| # Claude Code Setup Guide |
| |
| > **Note:** This guide is for developers setting up Claude Code. AI agents should ignore this file. |
| > |
| |
| ## Installation |
| |
| 1. **CLI:** Check the official https://code.claude.com/docs/en/setup doc |
| |
| 2. **IntelliJ Plugin:** Install "Claude Code [Beta]" from the plugin marketplace |
| |
| 3. **MCP Server:** Settings | Tools | MCP Server → Click "Auto-Configure for Claude Code" |
| |
| ## Verification |
| |
| - `/mcp` Claude command — Verify JetBrains MCP is enabled |
| - If missing, check `.claude/settings.local.json` file for `disabledMcpjsonServers` or `deniedMcpServers` |
| - `/model` Claude command — Ensure Opus 4.5 is selected (Sonnet 4.5 is less capable) |
| - The configured MCP server might have different names, but you might want to rename it to `jetbrains` for consistency |
| |
| ## Thinking Mode |
| |
| Thinking is **on by default** in CC >2.0.70 and it's discouraged to turn it off. |
| |
| Previously claude required prompting it to "think harder" or "ultrathink" – it's now not required |
| |
| ## Local Preferences |
| |
| `../.claude/local.md` file can be used to store local preferences |
