|
||
## Execution (5-Phase)
|
||
|
||
### Phase 1: Task Discovery
|
||
|
||
```javascript
|
||
const tasks = TaskList()
|
||
const myTasks = tasks.filter(t =>
|
||
t.subject.startsWith('SCOUT-') &&
|
||
t.owner === 'scout' &&
|
||
t.status === 'pending' &&
|
||
t.blockedBy.length === 0
|
||
)
|
||
|
||
if (myTasks.length === 0) return // idle
|
||
|
||
const task = TaskGet({ taskId: myTasks[0].id })
|
||
TaskUpdate({ taskId: task.id, status: 'in_progress' })
|
||
```
|
||
|
||
### Phase 2: Context & Scope Assessment
|
||
|
||
```javascript
|
||
// 确定扫描范围
|
||
const scanScope = task.description.match(/scope:\s*(.+)/)?.[1] || '**/*'
|
||
|
||
// 获取变更文件（如果有）
|
||
const changedFiles = Bash(`git diff --name-only HEAD~5 2>/dev/null || echo ""`)
|
||
.split('\n').filter(Boolean)
|
||
|
||
// 读取 shared memory 获取历史缺陷模式
|
||
const sessionFolder = task.description.match(/session:\s*(.+)/)?.[1] || '.'
|
||
let sharedMemory = {}
|
||
try { sharedMemory = JSON.parse(Read(`${sessionFolder}/shared-memory.json`)) } catch {}
|
||
const knownPatterns = sharedMemory.defect_patterns || []
|
||
|
||
// 确定扫描视角
|
||
const perspectives = ["bug", "security", "test-coverage", "code-quality"]
|
||
if (task.description.includes('ux')) perspectives.push("ux")
|
||
|
||
// 评估复杂度
|
||
function assessComplexity(desc) {
|
||
let score = 0
|
||
if (/全项目|全量|comprehensive|full/.test(desc)) score += 3
|
||
if (/security|安全/.test(desc)) score += 1
|
||
if (/multiple|across|cross|多模块/.test(desc)) score += 2
|
||
return score >= 4 ? 'High' : score >= 2 ? 'Medium' : 'Low'
|
||
}
|
||
const complexity = assessComplexity(task.description)
|
||
```
|
||
|
||
### Phase 3: Multi-Perspective Scan
|
||
|
||
```javascript
|
||
// Read commands/scan.md for full CLI Fan-out implementation
|
||
Read("commands/scan.md")
|
||
```
|
||
|
||
**核心策略**: 按视角并行执行 CLI 分析
|
||
|
||
```javascript
|
||
if (complexity === 'Low') {
|
||
// 直接使用 ACE 搜索 + Grep 进行快速扫描
|
||
const aceResults = mcp__ace-tool__search_context({
|
||
project_root_path: projectRoot,
|
||
query: "potential bugs, error handling issues, unchecked return values"
|
||
})
|
||
// 分析结果...
|
||
} else {
|
||
// CLI Fan-out: 每个视角一个 CLI 调用
|
||
for (const perspective of perspectives) {
|
||
Bash(`ccw cli -p "PURPOSE: Scan code from ${perspective} perspective to discover potential issues
|
||
TASK: • Analyze code patterns for ${perspective} problems • Identify anti-patterns • Check for common ${perspective} issues
|
||
MODE: analysis
|
||
CONTEXT: @${scanScope}
|
||
EXPECTED: List of findings with severity (critical/high/medium/low), file:line references, description
|
||
CONSTRAINTS: Focus on actionable findings only, no false positives" --tool gemini --mode analysis --rule analysis-assess-security-risks`, { run_in_background: true })
|
||
}
|
||
// 等待所有 CLI 完成，聚合结果
|
||
}
|
||
```
|
||
|
||
### Phase 4: Result Aggregation & Issue Creation
|
||
|
||
```javascript
|
||
// 聚合所有视角的发现
|
||
const allFindings = {
|
||
critical: [],
|
||
high: [],
|
||
medium: [],
|
||
low: []
|
||
}
|
||
|
||
// 去重：相同 file:line 的发现合并
|
||
// 排序：按严重性排列
|
||
// 与已知缺陷模式对比：标记重复发现
|
||
|
||
const discoveredIssues = allFindings.critical
|
||
.concat(allFindings.high)
|
||
.map((f, i) => ({
|
||
id: `SCOUT-ISSUE-${i + 1}`,
|
||
severity: f.severity,
|
||
perspective: f.perspective,
|
||
file: f.file,
|
||
line: f.line,
|
||
description: f.description,
|
||
suggestion: f.suggestion
|
||
}))
|
||
|
||
// 更新 shared memory
|
||
sharedMemory.discovered_issues = discoveredIssues
|
||
Write(`${sessionFolder}/shared-memory.json`, JSON.stringify(sharedMemory, null, 2))
|
||
|
||
// 保存扫描结果
|
||
Write(`${sessionFolder}/scan/scan-results.json`, JSON.stringify({
|
||
scan_date: new Date().toISOString(),
|
||
perspectives: perspectives,
|
||
total_findings: Object.values(allFindings).flat().length,
|
||
by_severity: {
|
||
critical: allFindings.critical.length,
|
||
high: allFindings.high.length,
|
||
medium: allFindings.medium.length,
|
||
low: allFindings.low.length
|
||
},
|
||
findings: allFindings,
|
||
issues_created: discoveredIssues.length
|
||
}, null, 2))
|
||
```
|
||
|
||
### Phase 5: Report to Coordinator
|
||
|
||
```javascript
|
||
const resultSummary = `发现 ${discoveredIssues.length} 个问题（Critical: ${allFindings.critical.length}, High: ${allFindings.high.length}, Medium: ${allFindings.medium.length}, Low: ${allFindings.low.length}）`
|
||
|
||
mcp__ccw-tools__team_msg({
|
||
operation: "log",
|
||
team: teamName,
|
||
from: "scout",
|
||
to: "coordinator",
|
||
type: discoveredIssues.length > 0 ? "issues_found" : "scan_ready",
|
||
summary: `[scout] ${resultSummary}`,
|
||
ref: `${sessionFolder}/scan/scan-results.json`
|
||
})
|
||
|
||
SendMessage({
|
||
type: "message",
|
||
recipient: "coordinator",
|
||
content: `## [scout] Scan Results
|
||
|
||
**Task**: ${task.subject}
|
||
**Perspectives**: ${perspectives.join(', ')}
|
||
**Status**: ${discoveredIssues.length > 0 ? 'Issues Found' : 'Clean'}
|
||
|
||
### Summary
|
||
${resultSummary}
|
||
|
||
### Top Findings
|
||
${discoveredIssues.slice(0, 5).map(i => `- **[${i.severity}]** ${i.file}:${i.line} - ${i.description}`).join('\n')}
|
||
|
||
### Scan Report
|
||
${sessionFolder}/scan/scan-results.json`,
|
||
summary: `[scout] SCOUT complete: ${resultSummary}`
|
||
})
|
||
|
||
TaskUpdate({ taskId: task.id, status: 'completed' })
|
||
|
||
// Check for next task
|
||
const nextTasks = TaskList().filter(t =>
|
||
t.subject.startsWith('SCOUT-') &&
|
||
t.owner === 'scout' &&
|
||
t.status === 'pending' &&
|
||
t.blockedBy.length === 0
|
||
)
|
||
|
||
if (nextTasks.length > 0) {
|
||
// Continue with next task → back to Phase 1
|
||
}
|
||
```
|
||
|
||
## Error Handling
|
||
|
||
| Scenario | Resolution |
|
||
|----------|------------|
|
||
| No SCOUT-* tasks available | Idle, wait for coordinator assignment |
|
||
| CLI tool unavailable | Fall back to ACE search + Grep inline analysis |
|
||
| Scan scope too broad | Narrow to changed files only, report partial results |
|
||
| All perspectives return empty | Report clean scan, notify coordinator |
|
||
| CLI timeout | Use partial results, note incomplete perspectives |
|
||
| Critical issue beyond scope | SendMessage issues_found to coordinator |
|
