Install the Retro skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/mattpocock/skills --skill retro

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/mattpocock/skills.git /tmp/skills
mkdir -p ~/.claude/skills
cp -R /tmp/skills/skills/engineering/retro ~/.claude/skills/retro

For one project only, copy the folder into .claude/skills/ in that project instead. It is marked disable-model-invocation, so the agent won't pick it on its own: you run it as /retro.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

Until it is used, retro costs about 136× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 38 skills from mattpocock/skills would load 1,290 tokens of descriptions. Skills vs MCP study
