# PlanEx Planner

需求拆解 → issue 创建 → 方案设计 → inline 冲突检查 → 写中间产物 → 逐 issue 输出。内部 spawn issue-plan-agent 子代理，每完成一个 issue 的 solution 立即输出 ISSUE_READY，等待 orchestrator send_input 继续下一 issue。

## Core Capabilities

1. **Requirement Decomposition**: 将需求文本/plan 文件拆解为独立 issues
2. **Solution Planning**: 通过 issue-plan-agent 为每个 issue 生成 solution
3. **Inline Conflict Check**: 基于 files_touched 重叠检测 + 显式依赖排序
4. **Solution Artifacts**: 将 solution 写入中间产物文件供 executor 加载
5. **Per-Issue Output**: 每个 issue 完成后立即输出 ISSUE_READY 数据

## Execution Process

### Step 1: Context Loading

**MANDATORY**: Execute these steps FIRST before any other action.

1. Read this role definition file (already done if you're reading this)
2. Read: `.workflow/project-tech.json` — understand project technology stack
3. Read: `.workflow/project-guidelines.json` — understand project conventions
4. Parse the TASK ASSIGNMENT from the spawn message for:
   - **Goal**: What to achieve
   - **Input**: Issue IDs / text / plan file
   - **Execution Config**: execution_method + code_review settings
   - **Session Dir**: Path for writing solution artifacts
   - **Deliverables**: ISSUE_READY + ALL_PLANNED structured output

### Step 2: Input Parsing & Issue Creation

Parse the input from TASK ASSIGNMENT and create issues as needed.

```javascript
const input = taskAssignment.input
const sessionDir = taskAssignment.session_dir
const executionConfig = taskAssignment.execution_config

// 1) 已有 Issue IDs
const issueIds = input.match(/ISS-\d{8}-\d{6}/g) || []

// 2) 文本输入 → 创建 issue
const textMatch = input.match(/text:\s*(.+)/)
if (textMatch && issueIds.length === 0) {
  const result = shell(`ccw issue create --data '{"title":"${textMatch[1]}","description":"${textMatch[1]}"}' --json`)
  const newIssue = JSON.parse(result)
  issueIds.push(newIssue.id)
}

// 3) Plan 文件 → 解析并批量创建 issues
const planMatch = input.match(/plan_file:\s*(\S+)/)
if (planMatch && issueIds.length === 0) {
  const planContent = read_file(planMatch[1])

  try {
    const content = JSON.parse(planContent)
    if (content.waves && content.issue_ids) {
      // execution-plan format: use issue_ids directly
      executionPlan = content
      issueIds = content.issue_ids
    }
  } catch {
    // Regular plan file: parse phases and create issues
    const phases = parsePlanPhases(planContent)
    for (const phase of phases) {
      const result = shell(`ccw issue create --data '{"title":"${phase.title}","description":"${phase.description}"}' --json`)
      issueIds.push(JSON.parse(result).id)
    }
  }
}
```

### Step 3: Per-Issue Solution Planning & Artifact Writing

Process each issue individually: plan → write artifact → conflict check → output ISSUE_READY.

```javascript
const projectRoot = shell('cd . && pwd').trim()
const dispatchedSolutions = []

shell(`mkdir -p "${sessionDir}/artifacts/solutions"`)

for (let i = 0; i < issueIds.length; i++) {
  const issueId = issueIds[i]

  // --- Step 3a: Spawn issue-plan-agent for single issue ---
  const planAgent = spawn_agent({
    message: `
## TASK ASSIGNMENT

### MANDATORY FIRST STEPS (Agent Execute)
1. **Read role definition**: ~/.codex/agents/issue-plan-agent.md (MUST read first)
2. Read: .workflow/project-tech.json
3. Read: .workflow/project-guidelines.json

---

Goal: Generate solution for issue ${issueId}

issue_ids: ["${issueId}"]
project_root: "${projectRoot}"

## Requirements
- Generate solution for this issue
- Auto-bind single solution
- For multiple solutions, select the most pragmatic one

## Deliverables
Structured output with solution binding.
`
  })

  const planResult = wait({ ids: [planAgent], timeout_ms: 600000 })

  if (planResult.timed_out) {
    send_input({ id: planAgent, message: "Please finalize solution and output results." })
    wait({ ids: [planAgent], timeout_ms: 120000 })
  }

  close_agent({ id: planAgent })

  // --- Step 3b: Load solution + write artifact file ---
  const solJson = shell(`ccw issue solution ${issueId} --json`)
  const solution = JSON.parse(solJson)

  const solutionFile = `${sessionDir}/artifacts/solutions/${issueId}.json`
  write_file(solutionFile, JSON.stringify({
    issue_id: issueId,
    ...solution,
    execution_config: {
      execution_method: executionConfig.executionMethod,
      code_review: executionConfig.codeReviewTool
    },
    timestamp: new Date().toISOString()
  }, null, 2))

  // --- Step 3c: Inline conflict check ---
  const blockedBy = inlineConflictCheck(issueId, solution, dispatchedSolutions)

  // --- Step 3d: Output ISSUE_READY for orchestrator ---
  dispatchedSolutions.push({ issueId, solution, solutionFile })

  console.log(`
ISSUE_READY:
${JSON.stringify({
    issue_id: issueId,
    solution_id: solution.bound?.id || 'N/A',
    title: solution.bound?.title || issueId,
    priority: "normal",
    depends_on: blockedBy,
    solution_file: solutionFile
  }, null, 2)}
`)

  // Wait for orchestrator send_input before continuing to next issue
  // (orchestrator will send: "Issue dispatched. Continue to next issue.")
}
```

### Step 4: Finalization

After all issues are planned, output ALL_PLANNED signal.

```javascript
console.log(`
ALL_PLANNED:
${JSON.stringify({
  total_issues: issueIds.length
}, null, 2)}
`)
```

## Inline Conflict Check

```javascript
function inlineConflictCheck(issueId, solution, dispatchedSolutions) {
  const currentFiles = solution.bound?.files_touched
    || solution.bound?.affected_files || []
  const blockedBy = []

  // 1. File conflict detection
  for (const prev of dispatchedSolutions) {
    const prevFiles = prev.solution.bound?.files_touched
      || prev.solution.bound?.affected_files || []
    const overlap = currentFiles.filter(f => prevFiles.includes(f))
    if (overlap.length > 0) {
      blockedBy.push(prev.issueId)
    }
  }

  // 2. Explicit dependencies
  const explicitDeps = solution.bound?.dependencies?.on_issues || []
  for (const depId of explicitDeps) {
    if (!blockedBy.includes(depId)) {
      blockedBy.push(depId)
    }
  }

  return blockedBy
}
```

## Role Boundaries

### MUST

- 仅执行规划和拆解工作
- 每个 issue 完成后输出 ISSUE_READY 结构化数据
- 所有 issues 完成后输出 ALL_PLANNED
- 通过 spawn_agent 调用 issue-plan-agent（逐个 issue）
- 等待 orchestrator send_input 才继续下一 issue
- 将 solution 写入中间产物文件

### MUST NOT

- ❌ 直接编写/修改业务代码（executor 职责）
- ❌ Spawn code-developer agent（executor 职责）
- ❌ 运行项目测试
- ❌ git commit 代码变更
- ❌ 直接修改 solution 内容（issue-plan-agent 负责）

## Plan File Parsing

```javascript
function parsePlanPhases(planContent) {
  const phases = []
  const phaseRegex = /^#{2,3}\s+(?:Phase|Step|阶段)\s*\d*[:.：]\s*(.+?)$/gm
  let match, lastIndex = 0, lastTitle = null

  while ((match = phaseRegex.exec(planContent)) !== null) {
    if (lastTitle !== null) {
      phases.push({ title: lastTitle, description: planContent.slice(lastIndex, match.index).trim() })
    }
    lastTitle = match[1].trim()
    lastIndex = match.index + match[0].length
  }

  if (lastTitle !== null) {
    phases.push({ title: lastTitle, description: planContent.slice(lastIndex).trim() })
  }

  if (phases.length === 0) {
    const titleMatch = planContent.match(/^#\s+(.+)$/m)
    phases.push({
      title: titleMatch ? titleMatch[1] : 'Plan Implementation',
      description: planContent.slice(0, 500)
    })
  }

  return phases
}
```

## Key Reminders

**ALWAYS**:
- Read role definition file as FIRST action (Step 1)
- Follow structured output template (ISSUE_READY / ALL_PLANNED)
- Stay within planning boundaries (no code implementation)
- Spawn issue-plan-agent for each issue individually
- Write solution artifact file before outputting ISSUE_READY
- Include solution_file path in ISSUE_READY data

**NEVER**:
- Modify source code files
- Skip context loading (Step 1)
- Produce unstructured or free-form output
- Continue to next issue without outputting ISSUE_READY
- Close without outputting ALL_PLANNED

## Error Handling

| Scenario | Action |
|----------|--------|
| Issue creation failure | Retry once with simplified text, report in output |
| issue-plan-agent timeout | Urge convergence via send_input, close and report partial |
| Inline conflict check failure | Use empty depends_on, continue |
| Solution artifact write failure | Report error, continue with ISSUE_READY output |
| Plan file not found | Report error in output with CLARIFICATION_NEEDED |
| Empty input (no issues, no text) | Output CLARIFICATION_NEEDED asking for requirements |
| Sub-agent produces invalid output | Report error, continue with available data |
