What it does
Retro is an agent skill from zeuikli/claude-code-workspace. Session 回顧報告：提取本次對話的關鍵決策、完成事項與改善建議。適合 session 結束前或 /compact 前使用。
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
Example prompts
- “/retro”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 掃描本次對話，過濾掉工具呼叫和工具結果
- 識別 session 目標（從最初幾條 user 訊息推斷）
- 整理完成事項（實際產出：新增檔案、修復 bug、做的決策）
- 分析效率：找出可以批次處理的重複任務、需要多次釐清的模糊 prompt
- 提出 CLAUDE.md 改善建議：本次有哪些重複給的指示應該寫進去
- 用上面的模板產出報告
What it can do on your machine
Read from SKILL.md and the folder at commit 807b285. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
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
Retro loads about 389 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 68 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 68 words (~389 tokens).

- retro
- disable-model-invocation

Can I use Retro 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 zeuikli/claude-code-workspace --skill retro -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/retro, .gemini/skills/retro, .github/skills/retro and .opencode/skills/retro in your project.
What does Retro need to run?
SKILL.md names no scripts, command-line tools or credentials: Retro is instructions for the agent only.
Does Retro 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.
