 # 开发指南

-## 先匹配任务与文件
+## 先确定领域与必读规范

-按用户要改的行为初判，定位后按实际修改或审查的文件复核，不要求用户说出“前端”“后端”或技能名。**命中多行就同时执行，先读取对应规范再修改或给出审查结论**；任务范围变化时补齐新命中项，已有上下文直接复用
+按用户意图、受影响行为与对象初判，定位后按实际文件复核，不要求用户说出“前端”“后端”或技能名。**所有命中行共同构成本次必读规范，先读完再确定方案、修改或给出审查结论**；跨领域叠加，不能只选最像当前步骤的一行

-| 命中条件，操作或文件满足其一即可 | 必须执行 |
+职责边界决定问题由谁修复；即使代码位于账号、调度或 API 模块，只要影响插件接入或为插件增加处理，也命中插件边界。确定方案时说明相关业务事实的归属及已有实现的复用依据，不能以功能恢复或测试通过替代职责判断

 In repositories indexed by CodeGraph (a `.codegraph/` directory exists at the repo root), reach for it BEFORE grep/find or reading files when you need to understand or locate code:

+- **Index freshness**: Run `codegraph sync` from the repository root before the first code query in a task. After pulling updates, switching branches, or changing code, run it again before the next query so symbols and call paths match the working tree. If synchronization fails, report the failure and verify against current source rather than treating the index as current.
 - **MCP tools** (when available): `codegraph_explore` answers most code questions in one call — the relevant symbols' verbatim source plus the call paths between them. `codegraph_node` returns one symbol's source + callers, or reads a whole file with line numbers. If the tools are listed but deferred, load them by name via tool search.
 - **Shell** (always works): `codegraph explore "<symbol names or question>"` and `codegraph node <symbol-or-file>` print the same output.

 - 回应已有能力、暂不支持或未采纳的建议时，结合场景说明可用入口或具体原因，有可行替代办法时一并说明，再交代必要边界；避免只回复“已有功能”“重复问题”“不在范围内”等结论
 - 需要补充材料或配合操作时，先利用已有信息，只询问仍缺少的部分，说明用途和最小范围；例如“佬，方便再观察几次吗？如果还出现，可以附一下对应请求的诊断包，便于对照终态用量”
