Agf running release retro

Running Release Retrospective

Use this skill when:

• product-lead has just pushed a MAJOR (vX.0.0) or MINOR (vX.Y.0) release tag and created the GitHub release
• The user typed /agf-release-retro vX.Y.Z and the slash dispatched here

Applicability — PATCH is excluded

Parse vX.Y.Z to gate execution:

retro 是 release 后的建议复盘（非强制 gate，见 versioning.md step 7）；本 skill 在用户主动触发 /agf-release-retro 时运行。

• Y=0 ∧ Z=0 → MAJOR, retro applies — proceed
• Y>0 ∧ Z=0 → MINOR, retro applies — proceed
• Z>0 → PATCH, abort with message: "PATCH release — retro not applicable per versioning.md, exiting."

If the version is PATCH, do not proceed.

Pre-conditions

All must pass before the execution sequence. On any failure, SendMessage product-lead the specific failure and do not proceed:

• CHANGELOG.md contains section ## [vX.Y.Z]（不再要求"pushed to origin"——下条 gh release view 已隐含 release 必须可见于 GitHub）
• git tag -l vX.Y.Z returns the tag
• gh release view vX.Y.Z returns the release

Execution sequence

1. Copy template and pre-fill header

Copy docs/reviews/retro-_TEMPLATE.md to docs/reviews/retro-vX.Y.Z-YYYY-MM-DD.md (use today's date). Pre-fill:

• Title with version and one-sentence release summary
• Release date (from git tag annotated date or gh release view --json createdAt)
• Link to CHANGELOG [vX.Y.Z](../../CHANGELOG.md)

2. Draft §1 (Progress)

Read CHANGELOG ## [vX.Y.Z] section and any linked PRD / ADR. Write §1 with:

• 起点（前一版 release 日期，或本版本 PRD 立项日期，取较晚者）→ tag 日期：N 天
• 范围调整 / 关键卡点（major diffs from original scope，blockers，why they happened）

3. Dispatch self-report tasks

Use Agent({subagent_type: ..., prompt: ...}) to send parallel self-report prompts to roles that contributed to this release:

• code-reviewer — code review severity distribution, rejection rates, SIT Audit verdicts (Pass / Pass with concerns / Redo SIT counts)
• qa-engineer — E2E / UAT failure counts, AC gaps missed until production (SIT is dev-owned; not in qa scope)
• Contributing execution-layer roles (backend-dev / frontend-dev / ai-agent-dev / ml-engineer / any miniapp-*) — implementation blockers, rework root causes
• tech-lead — only if this release contains an ADR change

Each role returns ≤3 highlights / ≤3 pains / ≤3 Action item candidates.

4. Integrate role inputs into §1–§4

Read each returned self-report and integrate into:

• §1: update with timeline/blocker insights
• §2: add quality metrics (code-review severity, test failure counts, production gaps)
• §3: 摘 /usage 的 4 类 token 字段（input_tokens / output_tokens / cache_creation_input_tokens / cache_read_input_tokens）+ 总 cost + cache hit ratio，按 cost-budget.md 分档明确写"本 release 落 Small / Medium / Large 哪档"（或"不涉 cost"）。这是跨 release 对比与 sweet-spot 判定的唯一数据来源。 /usage 实数强制：4 类实数由用户在会话里跑 /usage 贴给 product-lead（/usage 是 Claude Code 交互命令，agent 无法自跑）；§3 缺任一实数则本 retro 不得标记完成、不得进 Step 7——SendMessage 用户索要后等待。
• §4: note workflow frictions and template improvements

Deduplicate Action item candidates and draft §5 (Action Items table)。§5 表必须带「继承次数」列：新项 = 0；承自上一轮 §5 的项 = 上一轮该项值 +1。

4.1 Feature cycle time trend (≥3 retros 后强制评估)

项目声明不统计 Velocity / Burndown（见 product-workflow.md §4.4），但跨 retro 的"起点 → tag 日期"数据天然存在。累计 ≥3 个 retro 后强制做趋势评估，作为 Velocity 的隐式形式。

执行：

1. ls docs/reviews/retro-v*.md | sort 列出全部历史 retro
2. 从每份 retro §1 抽取 "起点 → tag 日期：N 天" + actual work 时长
3. 跨 retro 比对趋势：稳定 / 下降（团队效率提升）/ 上升（出现系统性阻塞）
4. 若 ≥3 retro 显示上升趋势 → 必须列为 §5 Action Item 候选，分析是流程问题 / 工具问题 / 范围问题
5. 若 <3 retro：本节写 "数据点不足（当前 N 个 retro），不下结论"

写入 §1 末尾或 §4 流程协作节，不另起独立小节，避免文档膨胀。

4.2 Action 继承 Gate（硬规则：禁止第三次继承）

任一 action 继承次数已 ≥2（上一轮 §5 该项「继承次数」列 ≥2）时，本轮必须二选一，不得再入 §5：

• (a) 落地为硬手段：hook / lint 断言 / 模板必填字段 / 带死线的 gh issue —— §0 标 done 并附证据链接
• (b) 显式 dropped：§0 标 dropped + 一句话放弃理由

本轮 §5 出现「继承次数」≥3 的行即非法（= 第三次继承），verification gate 直接 fail。

4.3 代码膨胀趋势快照（ADR-030 AC-2）

release 时跑 codemap bloat-snapshot --note vX.Y.Z 记一帧膨胀指标（dup_rate / 复杂度 / 死代码 + LOC context）到 .agf/bloat-trend.json（committed、append-only）。retro 可选 codemap bloat-trend --render md 看趋势——判断膨胀是否在长。LOC 是「上下文·非目标」虚荣指标，看趋势时关注质量（重复率 / 复杂度 / 死代码）而非 LOC。

≥3 帧后可在 §1 或 §4 写一句趋势结论（稳定 / 恶化 / 改善）；<3 帧写 "数据点不足"。趋势回归（PR 让质量指标退步）由 agf-bloat-trend-precheck.sh 在 dev 报告前 advisory 提示（串 agf-advisory.sh，命中进 review-checklist §7）。

5. Decide §6 (Public version)

Decide: 是 (public) or 否 (not public).

• If 是: dispatch content-writer to produce docs/content/internal/[YYYY-MM-DD]-[slug].md from this retro as source material
• If 否: mark "否" in §6

5.1 可选：skill 内容质量盘点（MINOR retro 时建议）

按 skill agf-skill-stocktake 对 .claude/skills/agf-*/SKILL.md 做内容质量盘点（5 维度 checklist + Keep/Improve/Update/Retire/Merge 裁定）。可选步骤、不进 verification gate——跳过不影响 retro 完成；产出的 Update/Retire 项作为 §5 Action item 候选。

6. Verification gate

All must pass before commit:

• §0 is written (首个 retro: explicit "首个 retro，无前置项"; subsequent: table filled from prior release §5)
• Action 继承 Gate 已应用（§4.2）：§5 带「继承次数」列且所有行 ≤2；上一轮 §5 中继承次数 ≥2 的项本轮已 (a) 落地为硬手段（§0 done + 证据）或 (b) dropped + 理由，禁止第三次继承
• §3 含 /usage 4 类 token 实数（input / output / cache_read / cache_create，用户贴入）；缺任一实数 retro 不得标记完成
• §5 has ≥1 Action item OR explicit "本轮无显著改进项" + one-line reason
• Every §5 row has non-empty Owner column, non-empty Due column, and a numeric 继承次数 column

If any check fails, do not proceed to Step 7.

7. Commit

git add docs/reviews/retro-vX.Y.Z-YYYY-MM-DD.md
git commit -m "docs(retro): vX.Y.Z release retrospective"

Do not push.

Anti-patterns

• ❌ Action item without owner or without due date
• ❌ 同一 action 第三次继承（继承次数 ≥3 必须已落地为硬手段或 dropped，见 §4.2）
• ❌ §3 无 /usage 4 类 token 实数仍把 retro 标记完成（实数由用户贴入，缺则等待）
• ❌ §0 missing (首个 retro must explicitly state "首个 retro，无前置项")
• ❌ PATCH release forced into the template (should have aborted at Applicability gate)
• ❌ Retro content duplicates CHANGELOG (changelog = "what was built"; retro = "why and how to improve next time")

Outputs

• Final file: docs/reviews/retro-vX.Y.Z-YYYY-MM-DD.md
• Optional: docs/content/internal/[YYYY-MM-DD]-[slug].md (if §6 = 是)
• Action items from §5 become §0 inputs for the next release retro
