Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By melodic-software/claude-code-plugins (GitHub) · coding · 30 stars · scanned at commit 677e798
Mid-session retro checkpoint: a subagent files findings from the transcript so far into a running ledger, never applied; `arm` runs it after the session ends. Use when: 'running retro', 'checkpoint this session', 'watch this session in the background', or on a /loop.
Works with any agent that supports SKILL.md skills.

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'running-retro' ] || [ -L ~/.agents/skills/'running-retro' ]; then echo 'A skill folder named running-retro already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/session-flow/skills/running-retro' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/session-flow/skills/running-retro' ~/.agents/skills/'running-retro' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'running-retro' ~/.claude/skills/'running-retro' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
