 # Parallel Dev Cycle - Multi-Agent Development Workflow

 Multi-agent parallel development cycle using Codex subagent pattern with four specialized workers:
-1. **Requirements Analysis & Extension** (RA) - 需求分析及扩展
-2. **Exploration & Planning** (EP) - 探索规划
-3. **Code Development** (CD) - 代码开发
-4. **Validation & Archival Summary** (VAS) - 验证及归档总结
+1. **Requirements Analysis & Extension** (RA) - Requirement analysis and self-enhancement
+2. **Exploration & Planning** (EP) - Exploration and planning
+3. **Code Development** (CD) - Code development with debug strategy support
+4. **Validation & Archival Summary** (VAS) - Validation and archival summary

-每个 agent **仅维护一个主文档文件**，支持版本化、自动归档、完整历史追溯。
+Each agent **maintains one main document** (e.g., requirements.md, plan.json, implementation.md) that is completely rewritten per iteration, plus auxiliary logs (changes.log, debug-log.ndjson) that are append-only. Supports versioning, automatic archival, and complete history tracking.

 ## Arguments

 | Arg | Required | Description |
 |-----|----------|-------------|
-| TASK | No | Task description (for new cycle, mutually exclusive with --cycle-id) |
-| --cycle-id | No | Existing cycle ID to continue (from API or previous session) |
+| TASK | One of TASK or --cycle-id | Task description (for new cycle, mutually exclusive with --cycle-id) |
+| --cycle-id | One of TASK or --cycle-id | Existing cycle ID to continue (from API or previous session) |
+| --extend | No | Extension description (only valid with --cycle-id) |
 | --auto | No | Auto-cycle mode (run all phases sequentially) |
 | --parallel | No | Number of parallel agents (default: 4, max: 4) |

 ## Key Design Principles

-1. **Single File Per Agent**: 每个 agent 仅维护一个主文件（精简清晰）
-2. **Version-Based Overwrite**: 每个版本完全重写主文件
-3. **Automatic Archival**: 旧版本自动归档到 `history/` 目录
-4. **Complete Audit Trail**: Changes.log (NDJSON) 保留所有变更历史
-5. **Parallel Execution**: 四个 agent 同时工作，无需等待
-6. **File References**: 使用简短文件路径而非内容传递
+1. **Main Document + Auxiliary Logs**: Each agent maintains one main document (rewritten per iteration) and auxiliary logs (append-only)
+2. **Version-Based Overwrite**: Main documents completely rewritten per version; logs append-only
+3. **Automatic Archival**: Old main document versions automatically archived to `history/` directory
+4. **Complete Audit Trail**: Changes.log (NDJSON) preserves all change history
+5. **Parallel Coordination**: Four agents launched simultaneously; coordination via shared state and orchestrator
+6. **File References**: Use short file paths instead of content passing
+7. **Self-Enhancement**: RA agent proactively extends requirements based on context

 /parallel-dev-cycle TASK="Implement OAuth login"
 ```

-生成：
+Generates:
 ```
 requirements.md (v1.0.0)
-plan.md (v1.0.0)
-implementation.md (v1.0.0) - 如适用
-summary.md (v1.0.0) - 如适用
+exploration.md (v1.0.0)
+architecture.md (v1.0.0)

 ```

-**自动处理**：
-1. 读取当前 `requirements.md (v1.0.0)`
-2. 自动归档到 `history/requirements-v1.0.0.md`
-3. 重新创建 `requirements.md (v1.1.0)` - 完全覆盖
-4. 追加变更到 `changes.log` (NDJSON)
+**Automatic handling**:
+1. Read current `requirements.md (v1.0.0)`
+2. Auto-archive to `history/requirements-v1.0.0.md`
+3. Recreate `requirements.md (v1.1.0)` - complete overwrite
+4. Append changes to `changes.log` (NDJSON)

 ## Changes.log Format (NDJSON)

-保留永久审计日志（append-only，永不删除）：
+Permanent audit log (append-only, never deleted):

+## Debug Workflow
+
+When tests fail during implementation, the CD agent MUST initiate the hypothesis-driven debug workflow. This workflow systematically identifies and resolves bugs through structured hypothesis testing.
+
+### Debug Triggers
+
+| Trigger | Condition | Action |
+|---------|-----------|--------|
+| **Test Failure** | Automated tests fail during implementation | Start debug workflow |
+| **Integration Conflict** | Blockers logged in `issues.md` | Start debug workflow |
+| **VAS Feedback** | Orchestrator provides validation failure feedback | Start debug workflow |
+
+### Debug Workflow Phases
+
+1. **Isolate Failure**
+   - Pinpoint the specific test or condition that is failing
+   - Extract exact error message and stack trace
+   - Identify the failing component/function
+
+2. **Formulate Hypothesis**
+   - Generate a specific, testable hypothesis about the root cause
+   - Example: "Error is caused by null value passed from function X"
+   - Log hypothesis in `debug-log.ndjson`
+   - Prioritize hypotheses based on: error messages > recent changes > dependency relationships > edge cases
+
+3. **Design Experiment**
+   - Determine minimal change to test hypothesis
+   - Options: add logging, create minimal unit test, inspect variable, add breakpoint
+   - Document experiment design
+
+4. **Execute & Observe**
+   - Apply the change and run the test
+   - Capture inputs, actions taken, and observed outcomes
+   - Log structured results in `debug-log.ndjson`
+
+5. **Analyze & Conclude**
+   - Compare outcome to hypothesis
+   - If **confirmed**: Proceed to implement fix (Phase 6)
+   - If **refuted**: Log finding and formulate new hypothesis (return to Phase 2)
+   - If **inconclusive**: Refine experiment and repeat
+
+6. **Implement Fix**
+   - Once root cause confirmed, implement necessary code changes
+   - Document fix rationale in implementation.md
+   - Log fix in changes.log
+
+7. **Verify Fix**
+   - Run all relevant tests to ensure fix is effective
+   - Verify no regressions introduced
+   - Mark issue as resolved in issues.md
+

+
+### Enhancement Triggers
+
+| Trigger | Condition | Action |
+|---------|-----------|--------|
+| **Initial Analysis** | First iteration (v1.0.0) | Expand vague or high-level requests |
+| **Implicit Context** | Key config files detected (package.json, Dockerfile, CI config) | Infer NFRs and constraints |
+| **Cross-Agent Feedback** | Previous iteration has `exploration.identified_risks`, `cd.blockers`, or `vas.test_results.failed_tests` | Cover uncovered requirements |
+
+### Enhancement Strategies
+
+1. **Codebase Analysis**
+   - Scan key project files (package.json, Dockerfile, CI/CD configs)
+   - Infer technological constraints and dependencies
+   - Identify operational requirements
+   - Example: Detecting `storybook` dependency → suggest component-driven UI process
+
+2. **Peer Output Mining**
+   - Analyze EP agent's `exploration.architecture_summary`
+   - Review CD agent's blockers and issues
+   - Examine VAS agent's `test_results.failed_tests`
+   - Formalize insights as new requirements
+
+3. **Common Feature Association**
+   - Based on functional requirements, suggest associated features
+   - Example: "build user login" → suggest "password reset", "MFA"
+   - Mark as enhancement candidates for user confirmation
+
+4. **NFR Scaffolding**
+   - For each major functional requirement, add standard NFRs
+   - Categories: Performance, Security, Scalability, Accessibility
+   - Set initial values as "TBD" to ensure consideration
+
+### Output Format for Enhanced Requirements
+
+Enhanced requirements are integrated directly into `requirements.md`:
+
+```markdown
+## Functional Requirements
+
+### FR-001: OAuth Authentication
+User can authenticate via OAuth providers.
+**Status**: Defined (v1.0.0)
+**Priority**: High
+
+### FR-002: Password Reset (ENHANCED v1.0.0 by RA)
+Users can reset their password via email link.
+**Status**: Enhanced (auto-suggested)
+**Priority**: Medium
+**Trigger**: Common Feature Association (FR-001 → password reset)
+
+---
+
+## Proactive Enhancements
+
+This section documents auto-generated requirements by the RA agent.
+
+| ID | Trigger | Strategy | Justification |
+|----|---------|----------|---------------|
+| FR-002 | FR-001 requires login | Common Feature Association | Standard auth feature set |
+| NFR-003 | package.json has `jest` | Codebase Analysis | Test framework implies testability NFR |
+```
+
+### Integration Notes

+- Self-enhancement is **internal to RA agent** - no orchestrator changes needed
+- Read-only access to codebase and cycle state required
+- Enhanced requirements are **transparently marked** for user review
+- User can accept, modify, or reject enhanced requirements in next iteration

-## Changes.log 的重要性
+## Importance of Changes.log

-虽然主文档重新创建，但 **changes.log (NDJSON) 永久保留完整历史**：
+Although main document is completely rewritten, **changes.log (NDJSON) permanently preserves complete history**:

 ```bash
-# 查看所有变更
+# View all changes
 cat .workflow/.cycle/cycle-xxx.progress/ra/changes.log | jq .

-# 查看某个需求的历史
+# View history of specific requirement
 cat .workflow/.cycle/cycle-xxx.progress/ra/changes.log | jq 'select(.id=="FR-001")'

-# 按迭代查看变更
+# View changes by iteration
 cat .workflow/.cycle/cycle-xxx.progress/ra/changes.log | jq 'select(.iteration==2)'
 ```

-这样：
- **主文档**: 清晰简洁（当前状态）
- **Changes.log**: 完整追溯（所有历史）
- **History/**: 快照备份（按需查看）
+This way:
+- **Main Document**: Clear and concise (current state)
+- **Changes.log**: Complete traceability (all history)
+- **History/**: Snapshot backups (view on demand)

-## 推荐实施
+## Recommended Implementation

-1. ✅ 采用"重新创建"策略
-2. ✅ 主文档只保留"上一版本简要说明"
-3. ✅ 自动归档到 `history/` 目录
-4. ✅ Changes.log (NDJSON) 保留完整历史
-5. ✅ 可选：保留最近 3-5 个历史版本
+1. ✅ Adopt "Complete Rewrite" strategy
+2. ✅ Main document only keeps "previous version summary"
+3. ✅ Auto-archive to `history/` directory
+4. ✅ Changes.log (NDJSON) preserves complete history
+5. ✅ Optional: Keep most recent 3-5 historical versions

-这样既保持了文档简洁（Agent 友好），又保留了完整历史（审计友好）。
