| 上下文 | Knowledge Base ：guidelines & learning Review instructions：config Issue Lint MCP 没有查到使用 RAG，但配置里有部分 embed 模型 https://docs.coderabbit.ai/self-hosted/github#prepare-an-env-file  |
Basic Code Understanding：diff Advanced Code Understanding： RAG + AST + Symbol Indexing Lint Issue |
RAG(Qodo Aware) Dynamic Context Issue Best Practice |
| 自定义规则 | Review instructions + path-based patterns + AST rules Code guidelines + cursorrules + agent.md + CLAUDE.md + 等等 Learnings  |
custom-code-review-rules + Provide feedback on Bito-reported issues（类似 Learnings） + guidelines |
Custom Prompt （直接修改 Prompt） extra-instructions （在默认 Prompt 上叠加额外指令，CR 自定义规则使用这种方式） Best Practice + Auto（类似 Learnings） + Custom（类似guidelines） |
