What it does
Retrospective is an agent skill from pixel-cellar/Claude-Code-Game-Studios. 通过分析已完成的工作、速率、阻碍因素和模式来生成 Sprint 或里程碑回顾。产出可执行的洞见以指导下一次迭代。
Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Product & Project Management, covering Retrospectives. The repository describes itself as: 48 协同代理管理独立游戏开发的 Claude Code 架构 (中文本地化版本). The licence is MIT.
When your agent uses it
- Tasks that involve Retrospectives
Example prompts
- “/retrospective”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Write
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- 读取参数确定这是 Sprint 回顾
- 读取 Sprint 或里程碑计划从相应位置
- 读取 git log 以了解该 Sprint 或里程碑覆盖的时间段内
- 扫描已完成和未完成的任务，通过对比计划与实际交付物。检查
- 扫描代码库中的 TODO/FIXME 趋势
- 读取之前的回顾（如有），来自 production/sprints/ 或
- 生成回顾
- 保存回顾到相应位置
- 向用户输出摘要：完成率、速率趋势方向、首要阻碍项，以及最重要的行动项。
What it can do on your machine
Read from SKILL.md and the folder at commit 2c016ef. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Retrospective loads about 767 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 67 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

当此技能被调用时：
读取参数确定这是 Sprint 回顾 （
sprint-N）还是里程碑回顾（里程碑名称）。读取 Sprint 或里程碑计划从相应位置：
- Sprint 计划：
production/sprints/ - 里程碑定义：
production/milestones/
提取：计划任务、预估工作量、负责人和目标。
- Sprint 计划：
读取 git log 以了解该 Sprint 或里程碑覆盖的时间段内 实际提交了什么以及何时提交。
扫描已完成和未完成的任务，通过对比计划与实际交付物。检查：
- 按计划完成的任务
- 已完成但与计划有修改的任务
- 延期任务（未完成）
- Sprint 中途添加的任务（计划外工作）
- 被移除或缩减范围的任务
扫描代码库中的 TODO/FIXME 趋势：
- 统计当前的 TODO/FIXME/HACK 注释数
- 与上一 Sprint 的计数对比（如可用，检查之前的回顾）
- 注意技术债务是在增长还是减少
读取之前的回顾（如有），来自
production/sprints/或production/milestones/，以检查：- 之前的行动项是否已处理？
- 相同的问题是否在重复出现？
- 速率趋势如何？

### 总结
[2-3 句话整体评估：这是一个好的 Sprint/里程碑吗？下一步最重要的改变是什么？]保存回顾到相应位置：
- Sprint：

production/milestones/[里程碑名称]-retrospective.md
如目录不存在则创建。
- Sprint：
向用户输出摘要：完成率、速率趋势方向、首要阻碍项，以及最重要的行动项。
指南
- 要诚实和具体。模糊的回顾（"沟通可以更好"）只能产生模糊的改进。使用数据和示例。
- 关注系统性问题，而非个人责任。
- 行动项限制在 3-5 个。更多会分散注意力。
- 每个行动项必须有负责人和截止日期。
- 检查之前的行动项是否已完成。反复出现的未处理项是流程问题的信号。
- 如果这是里程碑回顾，还需评估里程碑目标是否达成，以及这对整体项目时间线意味着什么。

When should I use Retrospective?
Retrospective fits situations like: tasks that involve Retrospectives.
How do I install Retrospective in Claude Code?
Run `npx skills add pixel-cellar/Claude-Code-Game-Studios --skill retrospective -a claude-code`. Or copy the skill folder (.claude/skills/retrospective in pixel-cellar/Claude-Code-Game-Studios) into .claude/skills/retrospective in your project. Claude Code loads it when a task matches its description.
How do I install Retrospective in Codex?
Run `npx skills add pixel-cellar/Claude-Code-Game-Studios --skill retrospective -a codex`. Or copy the skill folder (.claude/skills/retrospective in pixel-cellar/Claude-Code-Game-Studios) into .agents/skills/retrospective in your project. Codex loads it when a task matches its description.
Can I use Retrospective in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pixel-cellar/Claude-Code-Game-Studios --skill retrospective -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/retrospective, .gemini/skills/retrospective, .github/skills/retrospective and .opencode/skills/retrospective in your project.
What does Retrospective need to run?
SKILL.md names no scripts, command-line tools or credentials: Retrospective is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Glob, Grep, Write.
Does Retrospective access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Retrospective safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Retrospective use?
Retrospective is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Retrospective use?
About 767 tokens (SKILL.md is roughly 3.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Retrospective?
Skills that share tags, products or a category with Retrospective: Weekly Engineering Retro (garrytan/gstack, 136k stars), Dough Execute Plan (terryyin/lizard, 2.5k stars), After Action Report (rampstackco/claude-skills, 940 stars) and Oral Paper Skill (Adkid-Zephyr/oral-paper-skill, 340 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
