Quick Ref: Trace design decisions through CASS sessions, handoffs, git, and artifacts. Output:.agents/research/YYYY-MM-DD-trace-*.md
YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.
快速参考: 通过CASS会话、工作交接记录、Git和工件追踪设计决策。输出文件:.agents/research/YYYY-MM-DD-trace-*.md
你必须执行此工作流程,不能仅进行描述。
When to Use
适用场景
- Trace HOW architectural decisions evolved
- Find WHEN a concept was introduced
- Understand WHY something was designed a certain way
- Build provenance chain for design decisions
For knowledge artifact lineage (learnings, patterns, tiers), use instead.
/provenanceCLI dependencies: cass (session search). If cass is unavailable, skip transcript search and rely on git log, handoff docs, and artifacts for decision tracing.
.agents/- 追踪架构决策的演变过程
- 查找概念的引入时间
- 理解某项设计的原因
- 为设计决策构建溯源链
若需追踪知识工件的溯源(经验、模式、层级),请使用。
/provenanceCLI依赖: cass(会话搜索工具)。若cass不可用,则跳过会话记录搜索,仅依赖Git日志、交接文档和目录下的工件进行决策追踪。
.agents/Execution Steps
执行步骤
Given :
/trace <concept>当输入时:
/trace <concept>Step 1: Classify Target Type
步骤1:分类目标类型
Determine what kind of provenance to trace:
IF target is a file path (contains "/" or "."):
→ Use /provenance (artifact lineage)
IF target is a git ref (sha, branch, tag):
→ Use git-based tracing (Step 2b)
ELSE (keyword/concept):
→ Use design decision tracing (Step 2a)确定需要追踪的溯源类型:
如果目标是文件路径(包含 "/" 或 "."):
→ 使用 /provenance(工件溯源)
如果目标是Git引用(哈希值、分支、标签):
→ 使用基于Git的追踪(步骤2b)
其他情况(关键词/概念):
→ 使用设计决策追踪(步骤2a)Step 2a: Design Decision Tracing (Concepts)
步骤2a:设计决策追踪(针对概念)

Step 2b: Git-Based Tracing (Commits/Refs)
步骤2b:基于Git的追踪(针对提交/引用)
For git refs, trace the commit history:
bash
undefined对于Git引用,追踪提交历史:
bash
undefinedGet commit details
获取提交详情
git show --stat <ref>
git show --stat <ref>
Get commit ancestry
获取提交祖先链
git log --oneline --ancestry-path <ref>..HEAD | head -20
git log --oneline --ancestry-path <ref>..HEAD | head -20
Find related commits
查找相关提交
git log --oneline --all --grep="$(git log -1 --format=%s <ref> | head -c 50)" | head -10
undefinedgit log --oneline --all --grep="$(git log -1 --format=%s <ref> | head -c 50)" | head -10
undefinedStep 3: Build Timeline
步骤3:构建时间线
Merge results from all sources into a single timeline:
markdown
| Date | Source | Event | Evidence |
|------|--------|-------|----------|
| YYYY-MM-DD | CASS | First mention in session | session-id, snippet |
| YYYY-MM-DD | Handoff | Decision recorded | handoff-file, context |
| YYYY-MM-DD | Git | Implementation committed | commit-sha, message |
| YYYY-MM-DD | Research | Documented in research | research-file |Deduplication rules:
- Same content within 24 hours = single event (note multiple sources)
- Same session ID = single event
- Preserve ALL sources as evidence
Sorting:
- Chronological order (oldest first)
- Show evolution of the concept over time
将所有来源的结果合并为单一时间线:
markdown
| 日期 | 来源 | 事件 | 证据 |
|------|--------|-------|----------|
| YYYY-MM-DD | CASS | 首次在会话中提及 | 会话ID、片段 |
| YYYY-MM-DD | 交接文档 | 记录决策 | 交接文件、上下文 |
| YYYY-MM-DD | Git | 提交实现 | 提交哈希、信息 |
| YYYY-MM-DD | 研究文档 | 记录在研究文档中 | 研究文件 |去重规则:
- 24小时内的相同内容 = 单个事件(注明多个来源)
- 相同会话ID = 单个事件
- 保留所有来源作为证据
排序规则:
- 按时间顺序(从旧到新)
- 展示概念随时间的演变过程
Step 4: Extract Key Decisions
步骤4:提取关键决策
For each event in timeline, identify:
- What changed: The decision or evolution
- Why: Reasoning if available
- Who: Session/author/commit author
- Evidence: Link to source (session path, file, commit)
针对时间线中的每个事件,识别:
- 变更内容: 决策或演变点
- 原因: 若有则记录推理过程
- 相关人员: 会话参与者/作者/提交作者
- 证据: 来源链接(会话路径、文件、提交)
Step 5: Write Trace Report
步骤5:撰写追踪报告
Write to:
.agents/research/YYYY-MM-DD-trace-<concept-slug>.mdmarkdown
undefined写入路径:
.agents/research/YYYY-MM-DD-trace-<concept-slug>.mdmarkdown
undefinedTrace: <Concept>
追踪报告:<概念>
Date: YYYY-MM-DD
Query: <original concept>
Sources searched: CASS, Handoffs, Git, Research
日期: YYYY-MM-DD
查询词: <原始概念>
搜索来源: CASS、交接文档、Git、研究文档

Handling Edge Cases
边缘情况处理
No CASS Results
无CASS结果
IF cass search returns 0 results:
- Log: "No session transcripts mention '<concept>'"
- Continue with other sources
- Note in report: "Concept not found in session history"如果cass搜索返回0条结果:
- 记录:"会话记录中未提及'<concept>'"
- 继续使用其他来源
- 在报告中注明:"会话历史中未找到该概念"No Handoff Documents
无交接文档
IF .agents/handoff/ doesn't exist OR no matches:
- Log: "No handoff documents mention '<concept>'"
- Continue with other sources
- Note in report: "Concept not documented in handoffs"如果.agents/handoff/目录不存在或无匹配结果:
- 记录:"交接文档中未提及'<concept>'"
- 继续使用其他来源
- 在报告中注明:"交接文档中未记录该概念"Ambiguous Concept (Too Many Results)
概念模糊(结果过多)
IF CASS returns >20 results:
- Show top 10 by score
- Ask user: "Many sessions mention this. Want to narrow by date range or workspace?"
- Suggest related but more specific concepts如果CASS返回超过20条结果:
- 展示得分前10的结果
- 询问用户:"多个会话提及该概念,是否需要按日期范围或工作区缩小范围?"
- 建议相关但更具体的概念All Sources Empty
所有来源无结果
IF all 4 searches return nothing:
- Report: "No provenance found for '<concept>'"
- Suggest: "Try related terms: <suggestions>"
- Ask: "Is this concept documented somewhere else?"如果4种搜索均无结果:
- 反馈:"未找到'<concept>'的溯源信息"
- 建议:"尝试相关术语:<建议词>"
- 询问:"该概念是否记录在其他位置?"Key Rules
核心规则
- Search ALL sources - CASS, handoffs, git, research
- Build timeline - chronological evolution is the goal
- Cite evidence - every claim needs a source
- Handle gaps gracefully - not all concepts are in all sources
- Write report - trace must produce artifact
.agents/research/
- 搜索所有来源 - CASS、交接文档、Git、研究文档
- 构建时间线 - 目标是展示按时间顺序的演变过程
- 引用证据 - 每个结论都需要来源支持
- 优雅处理空白 - 并非所有概念都存在于所有来源中
- 撰写报告 - 追踪必须生成目录下的工件
