Phase 1: Locate Session Files

阶段1：定位会话文件

Step 1.1: Find Session Files

步骤1.1：查找会话文件

Session files are located in

~/.claude/

bash

undefined

会话文件存储在

~/.claude/

目录下：

bash

undefined

Main session log

主会话日志

~/.claude/projects/-{encoded-cwd}/{sessionId}.jsonl

Debug log (detailed)

调试日志（详细）

~/.claude/debug/{sessionId}.txt

Agent transcripts (if subagents were used)

Agent对话记录（若使用了子代理）

~/.claude/projects/-{encoded-cwd}/agent-{agentId}.jsonl


Use script to locate files:
```bash
${baseDir}/scripts/find-session-files.sh {sessionId}

~/.claude/projects/-{encoded-cwd}/agent-{agentId}.jsonl


使用脚本定位文件：
```bash
${baseDir}/scripts/find-session-files.sh {sessionId}

Step 1.2: Verify Files Exist

步骤1.2：验证文件是否存在

Check all required files exist before proceeding. If debug log is missing, analysis will be limited.

在继续分析前检查所有必要文件是否存在。若缺少调试日志，分析范围将受限。

Phase 2: Parse Target SKILL.md

阶段2：解析目标SKILL.md

Step 2.1: Extract Expected Components

步骤2.1：提取预期组件

Read the target SKILL.md and identify:

From YAML Frontmatter:

```
hooks.PreToolUse
```
- Expected PreToolUse hooks and matchers
```
hooks.PostToolUse
```
- Expected PostToolUse hooks
```
hooks.Stop
```
- Expected Stop hooks
```
hooks.SubagentStop
```
- Expected SubagentStop hooks
```
allowed-tools
```
- Tools the skill is allowed to use

From Markdown Body:

SubAgents mentioned (
```
Task(subagent_type="...")
```
)
Skills called (
```
Skill("...")
```
)
Artifacts created (
```
.dev-flow/drafts/
```
,
```
.dev-flow/plans/
```
, etc.)
Workflow steps and conditions

读取目标SKILL.md并识别以下内容：

从YAML前置元数据中：

```
hooks.PreToolUse
```
- 预期的PreToolUse钩子及匹配器
```
hooks.PostToolUse
```
- 预期的PostToolUse钩子
```
hooks.Stop
```
- 预期的Stop钩子
```
hooks.SubagentStop
```
- 预期的SubagentStop钩子
```
allowed-tools
```
- 技能允许使用的工具

从Markdown正文中：

提及的SubAgents（
```
Task(subagent_type="...")
```
）
调用的技能（
```
Skill("...")
```
）
创建的工件（
```
.dev-flow/drafts/
```
、
```
.dev-flow/plans/
```
等）
工作流步骤及条件

Step 2.2: Build Expected Behavior Checklist

步骤2.2：构建预期行为检查清单

Create checklist from SKILL.md analysis:

markdown

undefined

根据SKILL.md的分析结果创建检查清单：

markdown

undefined

Expected Behavior

预期行为

SubAgents

Explore agent called (parallel, run_in_background)
gap-analyzer called before plan generation
reviewer called after plan creation

调用了Explore agent（并行、后台运行）
在生成计划前调用了gap-analyzer
在创建计划后调用了reviewer

Hooks

PreToolUse[Edit|Write] triggers plan-guard.sh
Stop hook validates reviewer approval

PreToolUse[Edit|Write]触发了plan-guard.sh
Stop钩子验证了reviewer的批准

Artifacts

工件

Draft file created at .dev-flow/drafts/{name}.md
Plan file created at .dev-flow/plans/{name}.md
Draft file deleted after OKAY

在.dev-flow/drafts/{name}.md路径下创建了草稿文件
在.dev-flow/plans/{name}.md路径下创建了计划文件
获得OKAY后删除了草稿文件

Workflow

工作流

Interview Mode before Plan Generation
User explicit request triggers plan generation
Reviewer REJECT causes revision loop

---

生成计划前进入访谈模式
用户明确请求触发计划生成
Reviewer的REJECT指令触发修订循环

---

Phase 3: Analyze Debug Log

阶段3：分析调试日志

The debug log (

~/.claude/debug/{sessionId}.txt

) contains detailed execution traces.

调试日志（

~/.claude/debug/{sessionId}.txt

）包含详细的执行轨迹。

Step 3.1: Extract SubAgent Calls

步骤3.1：提取SubAgent调用记录

Search patterns:

SubagentStart with query: {agent-name}
SubagentStop with query: {agent-id}

Use script:

bash

${baseDir}/scripts/extract-subagent-calls.sh {debug-log-path}

搜索以下模式：

SubagentStart with query: {agent-name}
SubagentStop with query: {agent-id}

使用脚本：

bash

${baseDir}/scripts/extract-subagent-calls.sh {debug-log-path}

Step 3.2: Extract Hook Events

步骤3.2：提取Hook事件

Search patterns:

Getting matching hook commands for {HookEvent} with query: {tool-name}
Matched {N} unique hooks for query "{query}"
Hooks: Processing prompt hook with prompt: {prompt}
Hooks: Prompt hook condition was met/not met
permissionDecision: allow/deny

Use script:

bash

${baseDir}/scripts/extract-hook-events.sh {debug-log-path}

搜索以下模式：

Getting matching hook commands for {HookEvent} with query: {tool-name}
Matched {N} unique hooks for query "{query}"
Hooks: Processing prompt hook with prompt: {prompt}
Hooks: Prompt hook condition was met/not met
permissionDecision: allow/deny

使用脚本：

bash

${baseDir}/scripts/extract-hook-events.sh {debug-log-path}

Step 3.3: Extract Tool Calls

步骤3.3：提取工具调用记录

Search patterns:

executePreToolHooks called for tool: {tool-name}
File {path} written atomically

搜索以下模式：

executePreToolHooks called for tool: {tool-name}
File {path} written atomically

Step 3.4: Extract Hook Results

步骤3.4：提取Hook执行结果

For prompt-based hooks, find the model response:

Hooks: Model response: {
  "ok": true/false,
  "reason": "..."
}

对于基于提示的钩子，查找模型响应：

Hooks: Model response: {
  "ok": true/false,
  "reason": "..."
}

Phase 4: Verify Artifacts

阶段4：验证工件

Step 4.1: Check File Creation

步骤4.1：检查文件创建情况

For each expected artifact:

Search debug log for

FileHistory: Tracked file modification for {path}

Search for
```
File {path} written atomically
```
Verify current filesystem state

对于每个预期工件：

在调试日志中搜索

FileHistory: Tracked file modification for {path}

搜索
```
File {path} written atomically
```
验证当前文件系统状态

Step 4.2: Check File Deletion

步骤4.2：检查文件删除情况

For files that should be deleted:

Search for
```
rm
```
commands in Bash calls
Verify file no longer exists on filesystem

对于应被删除的文件：

在Bash调用记录中搜索
```
rm
```
命令
验证文件已不存在于文件系统中

Phase 5: Compare Expected vs Actual

阶段5：对比预期与实际情况

Step 5.1: Build Comparison Table

步骤5.1：构建对比表格

markdown

| Component | Expected | Actual | Status |
|-----------|----------|--------|--------|
| Explore agent | 2 parallel calls | 2 calls at 09:39:26 | ✅ |
| gap-analyzer | Called before plan | Called at 09:43:08 | ✅ |
| reviewer | Called after plan | 2 calls (REJECT→OKAY) | ✅ |
| PreToolUse hook | Edit\|Write matcher | Triggered for Write | ✅ |
| Stop hook | Validates approval | Returned ok:true | ✅ |
| Draft file | Created then deleted | Created→Deleted | ✅ |
| Plan file | Created | Exists (10KB) | ✅ |

markdown

| 组件 | 预期 | 实际 | 状态 |
|-----------|----------|--------|--------|
| Explore agent | 2次并行调用 | 在09:39:26进行了2次调用 | ✅ |
| gap-analyzer | 在生成计划前调用 | 在09:43:08调用 | ✅ |
| reviewer | 在创建计划后调用 | 2次调用（REJECT→OKAY） | ✅ |
| PreToolUse钩子 | Edit\|Write匹配器 | 针对Write操作触发 | ✅ |
| Stop钩子 | 验证批准状态 | 返回ok:true | ✅ |
| 草稿文件 | 创建后删除 | 创建→删除 | ✅ |
| 计划文件 | 已创建 | 存在（10KB） | ✅ |

Step 5.2: Identify Deviations

步骤5.2：识别偏差

Flag any mismatches:

Missing component calls
Wrong order of operations
Hook failures
Missing artifacts
Unexpected errors

标记所有不匹配项：

缺失的组件调用
错误的操作顺序
Hook执行失败
缺失的工件
意外错误
