Internal accuracy pass against v2.1.220 — no missing upstream features, but broken example code, disagreeing counts, and metadata drift.
Functional fixes: pre-commit.sh now exits 2 so it actually blocks; dependency-check.sh reads file_path from stdin JSON instead of $1; database-mcp.json uses ${DATABASE_URL}; broken fences repaired; three command templates had invalid skill names.
Factual corrections: /fork and /subtask unswapped and /subtask added; /fewer-permission-prompts; permissions.defaultMode; dontAsk/auto unreversed; 31 hook events verified name-by-name; subagent depth 3; skill precedence enterprise > project > personal; /output-style removed not deprecated; permissionDecision gained defer.
Follow-up review fixed defects the pass left behind: zh/vi headers claiming 31 events above 25-name lists, a surviving hardcoded DB credential in the MCP README examples, an unbalanced fence swallowing a metadata footer, and non-canonical tool names. All four translated CATALOG summary tables were recounted so their arithmetic holds.
Full detail in CHANGELOG.md under v2.1.220-r2.
Hooks 参考
Hooks 是在 Claude Code 事件发生时自动执行的 shell 命令，用来做格式化、校验、通知、审计等自动化工作。
概览
Hooks 是事件驱动的自动化机制。它们会在 Claude Code 发生某些动作时自动运行，不需要你手动触发。
常见用途：
- 写文件前自动格式化
- 提交前运行测试
- 扫描安全问题
- 记录 bash 命令
- 校验用户提示词
- 发送团队通知
Hook 类型
Claude Code 支持 31 个 hook 事件，按用途分为以下 4 组。事件的 handler 类型共 5 种：command、http、mcp_tool、prompt、agent。
- Tool Hooks：
PreToolUse、PostToolUse、PostToolUseFailure、PostToolBatch、PermissionRequest、PermissionDenied - Session Hooks：
SessionStart、Setup、SessionEnd、Stop、StopFailure、SubagentStart、SubagentStop - Task Hooks：
UserPromptSubmit、UserPromptExpansion、MessageDisplay、TaskCompleted、TaskCreated、TeammateIdle - Lifecycle Hooks：
ConfigChange、CwdChanged、DirectoryAdded、FileChanged、PreCompact、PostCompact、WorktreeCreate、WorktreeRemove、Notification、InstructionsLoaded、Elicitation、ElicitationResult
安装
mkdir -p ~/.claude/hooks
cp 06-hooks/*.sh ~/.claude/hooks/
chmod +x ~/.claude/hooks/*.sh
然后在 ~/.claude/settings.json 里配置：
{
"hooks": {
"PreToolUse": [
{
"matcher": "Write",
"hooks": [
{
"type": "command",
"command": "~/.claude/hooks/format-code.sh"
}
]
}
],
"PostToolUse": [
{
"matcher": "Write",
"hooks": [
{
"type": "command",
"command": "~/.claude/hooks/security-scan.sh"
}
]
}
]
}
}
使用方法
Hooks 会在匹配到事件时自动执行。你可以把它理解成 Claude Code 的事件回调。
常见示例
format-code.sh- 写入前自动格式化pre-commit.sh- 提交前跑测试security-scan.sh- 做安全扫描log-bash.sh- 记录 bash 命令validate-prompt.sh- 校验输入notify-team.sh- 发通知
最佳实践
- 把 hooks 保持短小明确
- 只做单一职责
- 先在本地测试
- 不要在 hook 里放复杂业务逻辑
- 对副作用保持谨慎
故障排查
- 检查文件路径和权限
- 确认脚本可执行
- 检查 settings.json 语法
- 查看 Claude Code 版本兼容性
