Break a plan or milestone brief into independently-grabbable vertical slices (tracer bullets), saved with `gsd_plan_milestone` by default (GitHub issues only on explicit confirmation). Prefers many thin slices over few thick ones and marks dependency order. Use when asked to "break this into slices", "decompose the plan", "vertical slices", "break into issues", or when a plan needs task-level decomposition.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'decompose-into-slices' ] || [ -L ~/.agents/skills/'decompose-into-slices' ]; then echo 'A skill folder named decompose-into-slices already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/open-gsd/gsd-pi' "$d" && git -C "$d" checkout --quiet 'c0bc9c4e7e0a8581aeac3af397031dc3a63d012e' -- 'src/resources/skills/decompose-into-slices' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/resources/skills/decompose-into-slices' ~/.agents/skills/'decompose-into-slices' && 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/'decompose-into-slices' ~/.claude/skills/'decompose-into-slices' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
