## Session Retrospective — 2026-03-19-D2

### Actions Taken

**PRP-2106: AF CLI Optimization v0.6 (full lifecycle)**
- Analyzed codebase, identified 7 optimization points → user selected 6
- Created PRP-2106, Worker (GLM) filled content
- COR-1602 review: 3 rounds (Codex 9.1→8.92→9.25, Gemini 8.5→9.7→9.8)
- Implemented 6 CHGs via TDD (COR-1500) + review (COR-1601):
  - CHG-1: DRY scan boilerplate → `_helpers.py` (9cfd493)
  - CHG-2: Lazy command loading → `LazyGroup` (b244f17)
  - CHG-3: List filtering → `--type/--prefix/--source` (2a63209)
  - CHG-4: JSON output → `--json` on list/status/read (e388b26)
  - CHG-5: af search → content search command (f1773b7)
  - CHG-6: af validate → health check command (eebdf36)
- Version bump 0.5.0 → 0.6.0, published to PyPI
- Codex full review: 9.8/10 PASS

**Help text improvements (D23)**
- Added epilog examples to list, search, validate commands (cd8869f)

**Document layer fix**
- Migrated ALF-* documents from PRJ (alfred_ops/rules/) to USR (~/.alfred/)

**5 new PRPs created:**
- ALF-2202: Team Skill Session Management (new/resume)
- ALF-2203: Multi-CHG Implementation Workflow SOP
- ALF-2204: Team Agent Health Monitoring (A+B+C)
- FXA-2116: Document Format Contract
- FXA-2117: AF Filter + Section Update

**Project setup**
- Created fx_alfred/CLAUDE.md for new session context
- Created Discussion Tracker FXA-2113

### Discussion Items (D18-D23)

| DN | Topic | Result |
|----|-------|--------|
| D18 | 每次 TDD 前必须读 COR-1500 | feedback memory |
| D19 | 进度 tracker 集成 SOP | ALF-2203 PRP |
| D20 | 后台 agent 监控 | ALF-2204 PRP |
| D21 | agent resume | ALF-2202 PRP |
| D22 | /team 派发方式 | ALF-2202 PRP + feedback memory |
| D23 | help text 改进 | committed cd8869f |

### Commits (fx_alfred)

| Hash | Description |
|------|------------|
| 9cfd493 | refactor: extract scan_or_fail and find_or_fail helpers (CHG-1) |
| b244f17 | feat: lazy command loading via LazyGroup (CHG-2) |
| 2a63209 | feat: add --type, --prefix, --source filters to af list (CHG-3) |
| e388b26 | feat: add --json output to list, status, and read commands (CHG-4) |
| f1773b7 | feat: add af search command for content search (CHG-5) |
| eebdf36 | feat: add af validate command for document health checks (CHG-6) |
| befd45f | chore: bump version to 0.6.0 + CHANGELOG |
| 512a323 | chore: update PKG document metadata and lockfile |
| cd8869f | docs: improve --help text with examples and valid values |

### Stats

| Metric | Value |
|--------|-------|
| Commits | 9 |
| Tests | 134 → 179 (+45 new) |
| Lines added | ~1,100 |
| Lines removed | ~120 |
| Commands added | 2 (search, validate) |
| PRPs created | 6 (1 implemented, 5 draft) |
| CHGs implemented | 6/6 |
| Review rounds | 14 total (PRP 3 + CHG 1-6 各 1-2) |
| PyPI release | v0.6.0 |

### Automation Candidates

| Pattern | Suggested Action | Priority |
|---------|-----------------|----------|
| Leader 手动贴进度更新 | ALF-2203 SOP 标准化 | High |
| Leader 手动 tail agent output | ALF-2204 自动监控 | High |
| 每次 /team 都要写长 prompt | 考虑 prompt templates | Medium |
| Codex 经常超时/auth 失败 | 自动重试机制 | Medium |

### Repeated Patterns

| Pattern | Count | Improvement |
|---------|-------|-------------|
| `/team new` → TDD → review → commit 循环 | 6 次 | ALF-2203 SOP 编排 |
| Codex 停掉后重派 | 3 次 | ALF-2202 resume + ALF-2204 监控 |
| 直接用 Agent 而非 Skill("team") | 全 session | feedback memory 已记录 |
| af list --root alfred_ops 每次都要写 | ~10 次 | 考虑 .alfredrc 或 auto-detect |

### Key Learnings

1. **PRP → CHG → TDD 流程有效** — 6 个 CHG 全部一次或两次 review 通过，零返工
2. **Codex 比 Gemini 严格但不稳定** — Codex 找出真问题（CHG-1 架构、CHG-6 layer check）但经常超时/auth 失败
3. **Gemini 更稳定更快** — 平均 2-3 分钟完成 review，Codex 要 3-10 分钟
4. **GLM 作为 Worker 很可靠** — 6 个 TDD 实现全部一次通过，测试质量高
5. **进度 tracker 对用户体验至关重要** — 用户多次在等待时问状态，需要主动反馈
6. **显式优于隐式** — 用户要求 /team 必须写 new/resume，不接受自动判断
7. **文档层级要正确** — ALF-* 放在 PRJ 层是错误的，应该从一开始就放 USR 层
8. **CLAUDE.md 应该在项目初期创建** — 而不是 session 末尾补
9. **Discussion Tracker 应该在 session 开始时创建** — 而不是中途补建
10. **COR-1500 不能跳过** — 即使 Leader "知道" TDD 流程，也必须让 Worker 读 SOP
