# Pre-Edit Safety Gate **This skill gates ALL code modifications. It is NOT optional. Skip it and your edits are invalid.** ## Trigger Invoke this skill BEFORE any of these actions: - Editing an existing file (`edit` tool) - Creating a new file (`write` tool) - Deleting or renaming code Do NOT skip for "simple changes", "one-liners", or "obvious fixes". Small edits cause regressions too. ## Tier Selection | 变更类型 | 模式 | 跳过项 | |---------|------|--------| | 纯文档/注释/格式 | **Lightweight** | Blast radius, Dependencies, Test coverage | | 逻辑/行为变更 | **Full** | 无（走完整流程） | 不确定时默认走 Full。若选择 Lightweight 但被 CRG 检测到风险，自动升级为 Full。 ## Pre-Edit Checklist (MUST complete all 5 before touching code) | # | Check | Command | Block rule | |---|-------|---------|------------| | 1 | **Project context** | `get_minimal_context(task="brief description")` | Required | | 2 | **Blast radius** | `get_impact_radius(detail_level="minimal")` | **risk=high → STOP**, re-evaluate approach | | 3 | **Dependencies** | **根据场景选其一**：`callees_of`（看被调方）、`callers_of`（看调用方）、`importers_of`（看引用方）。target 填函数名或类名 | Required | | 4 | **Style alignment** | Read target file + 2 neighboring files. Extract: indent width, naming style, import ordering, error-handling patterns | Required | | 5 | **Test coverage** | `query_graph(pattern="tests_for", target="<函数名或类名>")` | **No tests → write tests FIRST**, then edit code | ## Post-Edit Checklist (MUST complete all 4 after every edit) | # | Check | Command | Block rule | |---|----
