Decision protocol for the map-reduce / dynamic fan-out pattern in LM pipelines — "given list L, run f(item) for each item in parallel, then combine". Activates when the coder agent is about to process N items with N LM calls (per-doc summarize, per-query retrieve, per-candidate rank, parallel tool fan-out). Encodes the *when*, *how many at once*, *what to do when one fails*, and *how to reduce* — not the API of any single framework. Cross-framework: LangGraph `Send`, CrewAI parallel tasks / Flo…

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/'agentsop-map-reduce-fanout' ] || [ -L ~/.agents/skills/'agentsop-map-reduce-fanout' ]; then echo 'A skill folder named agentsop-map-reduce-fanout already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/agentsope/SkillAlchemy' "$d" && git -C "$d" checkout --quiet '955562e4416c483da946e9c95a1c3974ac52df3c' -- 'skills/agentsop-map-reduce-fanout' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/agentsop-map-reduce-fanout' ~/.agents/skills/'agentsop-map-reduce-fanout' && 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/'agentsop-map-reduce-fanout' ~/.claude/skills/'agentsop-map-reduce-fanout' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
