# Issue Plan Command (/issue:plan)

## Overview

Unified planning command using **issue-plan-agent** that combines exploration and planning into a single closed-loop workflow.

## Output Requirements

**Generate Files:**
1. `.workflow/issues/solutions/{issue-id}.jsonl` - Solution with tasks for each issue

**Return Summary:**
```json
{
  "bound": [{ "issue_id": "...", "solution_id": "...", "task_count": N }],
  "pending_selection": [{ "issue_id": "...", "solutions": [...] }],
  "conflicts": [{ "file": "...", "issues": [...] }]
}
```

**Completion Criteria:**
- [ ] Solution file generated for each issue
- [ ] Single solution → auto-bound via `ccw issue bind`
- [ ] Multiple solutions → returned for user selection
- [ ] Tasks conform to schema: `cat .claude/workflows/cli-templates/schemas/issue-task-jsonl-schema.json`
- [ ] Each task has quantified `delivery_criteria`

## Core Capabilities

- **Closed-loop agent**: issue-plan-agent combines explore + plan
- Batch processing: 1 agent processes 1-3 issues
- ACE semantic search integrated into planning
- Solution with executable tasks and delivery criteria
- Automatic solution registration and binding

## Storage Structure (Flat JSONL)

```
.workflow/issues/
├── issues.jsonl              # All issues (one per line)
├── queue.json                # Execution queue
└── solutions/
    ├── {issue-id}.jsonl      # Solutions for issue (one per line)
    └── ...
```

## Usage

```bash
/issue:plan <issue-id>[,<issue-id>,...] [FLAGS]

# Examples
/issue:plan GH-123                    # Single issue
/issue:plan GH-123,GH-124,GH-125      # Batch (up to 3)
/issue:plan --all-pending             # All pending issues

# Flags
--batch-size <n>      Max issues per agent batch (default: 3)
```

## Execution Process

```
Phase 1: Issue Loading
   ├─ Parse input (single, comma-separated, or --all-pending)
   ├─ Load issues from .workflow/issues/issues.jsonl
   ├─ Validate issues exist (create if needed)
   └─ Group into batches (max 3 per batch)

Phase 2: Unified Explore + Plan (issue-plan-agent)
   ├─ Launch issue-plan-agent per batch
   ├─ Agent performs:
   │   ├─ ACE semantic search for each issue
   │   ├─ Codebase exploration (files, patterns, dependencies)
   │   ├─ Solution generation with task breakdown
   │   └─ Conflict detection across issues
   └─ Output: solution JSON per issue

Phase 3: Solution Registration & Binding
   ├─ Append solutions to solutions/{issue-id}.jsonl
   ├─ Single solution per issue → auto-bind
   ├─ Multiple candidates → AskUserQuestion to select
   └─ Update issues.jsonl with bound_solution_id

Phase 4: Summary
   ├─ Display bound solutions
   ├─ Show task counts per issue
   └─ Display next steps (/issue:queue)
```

## Implementation

### Phase 1: Issue Loading (IDs Only)

```javascript
const batchSize = flags.batchSize || 3;
let issueIds = [];

if (flags.allPending) {
  // Get pending issue IDs directly via CLI
  const ids = Bash(`ccw issue list --status pending,registered --ids`).trim();
  issueIds = ids ? ids.split('\n').filter(Boolean) : [];

  if (issueIds.length === 0) {
    console.log('No pending issues found.');
    return;
  }
  console.log(`Found ${issueIds.length} pending issues`);
} else {
  // Parse comma-separated issue IDs
  issueIds = userInput.includes(',')
    ? userInput.split(',').map(s => s.trim())
    : [userInput.trim()];

  // Create if not exists
  for (const id of issueIds) {
    Bash(`ccw issue init ${id} --title "Issue ${id}" 2>/dev/null || true`);
  }
}

// Group into batches
const batches = [];
for (let i = 0; i < issueIds.length; i += batchSize) {
  batches.push(issueIds.slice(i, i + batchSize));
}

console.log(`Processing ${issueIds.length} issues in ${batches.length} batch(es)`);

TodoWrite({
  todos: batches.map((_, i) => ({
    content: `Plan batch ${i+1}`,
    status: 'pending',
    activeForm: `Planning batch ${i+1}`
  }))
});
```

### Phase 2: Unified Explore + Plan (issue-plan-agent)

```javascript
Bash(`mkdir -p .workflow/issues/solutions`);
const pendingSelections = [];  // Collect multi-solution issues for user selection

for (const [batchIndex, batch] of batches.entries()) {
  updateTodo(`Plan batch ${batchIndex + 1}`, 'in_progress');

  // Build minimal prompt - agent handles exploration, planning, and binding
  const issuePrompt = `
## Plan Issues

**Issue IDs**: ${batch.join(', ')}
**Project Root**: ${process.cwd()}

### Steps
1. Fetch: \`ccw issue status <id> --json\`
2. Explore (ACE) → Plan solution
3. Register & bind: \`ccw issue bind <id> --solution <file>\`

### Generate Files
\`.workflow/issues/solutions/{issue-id}.jsonl\` - Solution with tasks (schema: cat .claude/workflows/cli-templates/schemas/issue-task-jsonl-schema.json)

### Binding Rules
- **Single solution**: Auto-bind via \`ccw issue bind <id> --solution <file>\`
- **Multiple solutions**: Register only, return for user selection

### Return Summary
\`\`\`json
{
  "bound": [{ "issue_id": "...", "solution_id": "...", "task_count": N }],
  "pending_selection": [{ "issue_id": "...", "solutions": [{ "id": "...", "description": "...", "task_count": N }] }],
  "conflicts": [{ "file": "...", "issues": [...] }]
}
\`\`\`
`;

  // Launch issue-plan-agent - agent writes solutions directly
  const result = Task(
    subagent_type="issue-plan-agent",
    run_in_background=false,
    description=`Explore & plan ${batch.length} issues`,
    prompt=issuePrompt
  );

  // Parse summary from agent
  const summary = JSON.parse(result);

  // Display auto-bound solutions
  for (const item of summary.bound || []) {
    console.log(`✓ ${item.issue_id}: ${item.solution_id} (${item.task_count} tasks)`);
  }

  // Collect pending selections for Phase 3
  pendingSelections.push(...(summary.pending_selection || []));

  // Show conflicts
  if (summary.conflicts?.length > 0) {
    console.log(`⚠ Conflicts: ${summary.conflicts.map(c => c.file).join(', ')}`);
  }

  updateTodo(`Plan batch ${batchIndex + 1}`, 'completed');
}
```

### Phase 3: Multi-Solution Selection

```javascript
// Only handle issues where agent generated multiple solutions
if (pendingSelections.length > 0) {
  const answer = AskUserQuestion({
    questions: pendingSelections.map(({ issue_id, solutions }) => ({
      question: `Select solution for ${issue_id}:`,
      header: issue_id,
      multiSelect: false,
      options: solutions.map(s => ({
        label: `${s.id} (${s.task_count} tasks)`,
        description: s.description
      }))
    }))
  });

  // Bind user-selected solutions
  for (const { issue_id } of pendingSelections) {
    const selectedId = extractSelectedSolutionId(answer, issue_id);
    if (selectedId) {
      Bash(`ccw issue bind ${issue_id} ${selectedId}`);
      console.log(`✓ ${issue_id}: ${selectedId} bound`);
    }
  }
}
```

### Phase 4: Summary

```javascript
// Count planned issues via CLI
const plannedIds = Bash(`ccw issue list --status planned --ids`).trim();
const plannedCount = plannedIds ? plannedIds.split('\n').length : 0;

console.log(`
## Done: ${issueIds.length} issues → ${plannedCount} planned

Next: \`/issue:queue\` → \`/issue:execute\`
`);
```

## Error Handling

| Error | Resolution |
|-------|------------|
| Issue not found | Auto-create in issues.jsonl |
| ACE search fails | Agent falls back to ripgrep |
| No solutions generated | Display error, suggest manual planning |
| User cancels selection | Skip issue, continue with others |
| File conflicts | Agent detects and suggests resolution order |
