feat: US-012 - Add ShellTool tests
Added comprehensive test coverage for ShellTool (ExecTool) with 9 test cases: - TestShellTool_Success: Verifies successful command execution - TestShellTool_Failure: Verifies failed command execution with IsError flag - TestShellTool_Timeout: Verifies command timeout handling - TestShellTool_WorkingDir: Verifies custom working directory support - TestShellTool_DangerousCommand: Verifies safety guard blocks dangerous commands - TestShellTool_MissingCommand: Verifies error handling for missing command - TestShellTool_StderrCapture: Verifies stderr is captured and included - TestShellTool_OutputTruncation: Verifies long output is truncated - TestShellTool_RestrictToWorkspace: Verifies workspace restriction ShellTool implementation already conforms to ToolResult specification: - Success returns ForUser = command output - Failure returns IsError = true - ForLLM contains full output and exit code Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- **Gotchas encountered:** 测试文件使用 `map[string]interface{}` 作为 args 参数类型,与 Tool.Execute 签名一致。
|
||||
- **Useful context:** MessageTool 的设计模式是"用户已直接收到消息,所以 ForUser 为空且 Silent=true",避免重复发送。

## [2026-02-12] - US-012
|
||||
- What was implemented:
|
||||
- ShellTool 已经完全使用 ToolResult 返回值(无需修改实现)
|
||||
- 添加了完整的测试文件 `pkg/tools/shell_test.go`,包含 9 个测试用例
|
||||
- 测试覆盖了所有验收标准:
|
||||
- 成功返回 ForUser = 命令输出
|
||||
- 失败返回 IsError = true
|
||||
- ForLLM 包含完整输出和退出码
|
||||
- 自定义工作目录测试
|
||||
- 危险命令阻止测试
|
||||
- 缺少命令错误处理
|
||||
- Stderr 捕获测试
|
||||
- 输出截断测试
|
||||
- 工作空间限制测试
|
||||
|
||||
- Files changed:
|
||||
- `pkg/tools/shell_test.go` (新增)
|
||||
|
||||
- **Learnings for future iterations:**
|
||||
- **Patterns discovered:** ShellTool 实现已经符合 ToolResult 规范,只需要添加测试覆盖即可。测试覆盖了成功、失败、超时、自定义目录、安全防护等多种场景。
|
||||
- **Gotchas encountered:** 无
|
||||
- **Useful context:** ShellTool 的安全防护机制包括:危险命令检测(如 `rm -rf`)、工作空间路径遍历检测、命令超时控制。
