# CCG Domain Knowledge — Auto-routing Rules

When the user's request matches trigger keywords below, automatically READ the corresponding skill file to gain domain expertise before responding. These knowledge files are installed at `~/.claude/skills/ccg/domains/`.

**IMPORTANT**: Read the skill file FIRST, then respond. Do NOT fabricate domain knowledge from training data when a skill file exists.

## Security Domain (`domains/security/`) — NOT installed by default

> Security domain files contain red team/pentest reference content that may trigger antivirus false positives.
> They are NOT installed by default. To enable, manually copy from the npm package:
> `cp -r $(npm root -g)/ccg-ros2-workflow/templates/skills/domains/security/ ~/.claude/skills/ccg/domains/security/`

## Development Domain (`domains/development/`)

When the user is working with a specific programming language, read the corresponding skill file for language-specific best practices:

| Language | Skill File |
|----------|-----------|
| Python | `~/.claude/skills/ccg/domains/development/python.md` |
| Go | `~/.claude/skills/ccg/domains/development/go.md` |
| Rust | `~/.claude/skills/ccg/domains/development/rust.md` |
| TypeScript / JavaScript | `~/.claude/skills/ccg/domains/development/typescript.md` |
| Java / Kotlin | `~/.claude/skills/ccg/domains/development/java.md` |
| C / C++ | `~/.claude/skills/ccg/domains/development/cpp.md` |
| Shell / Bash | `~/.claude/skills/ccg/domains/development/shell.md` |

## Routing Rules

1. **Keyword match is fuzzy** — match on intent, not exact string. "How to do SQL injection testing" triggers `pentest.md`.
2. **Multiple matches** — if a request spans two domains, read both skill files.
3. **Language detection** — automatically detect the programming language from file extensions or context, then read the corresponding development skill.
4. **Read once per conversation** — no need to re-read the same skill file within the same conversation.
5. **Skill files are authoritative** — when a skill file contradicts training data, the skill file wins.
