What it does
Retro is an agent skill from neurofoo/agent-skills. Start-Stop-Continue retrospective identifying what to Start doing, Stop doing, and Continue doing. Use for sprint retros, personal reflection, team process reviews, or habit audits.
Its SKILL.md is about 560 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: Agent Skills for Claude Code and OpenCode. The licence is MIT.
When your agent uses it
- Personal reflection
- Team process reviews
Example prompts
- “/retro”
What it can do on your machine
Read from SKILL.md and the folder at commit 0e7ac2a. 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.
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 560 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 245 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.

Guidelines
- Be specific: "Start daily standups" not "communicate more"
- Be behavioral: Focus on actions, not attitudes
- Balance: Aim for 3-5 items per category
- Celebrate Continues: Don't skip this section—recognize what's working
- Assign owners: Unowned actions don't happen
- One priority: If everything is important, nothing is
