Run a list of work units to completion with an Agent Team: derive a dependency DAG and hot-file map, spawn one ephemeral teammate per unit (or combined group), drive each PR through pr-review-merge, smart-merge in waves, recover from crashes, and run a retrospective. Source-agnostic — the caller supplies a work-source adapter. A library skill invoked BY the /tm and /issues commands, not run directly by a user (it needs a caller-supplied adapter). TRIGGER when a command needs autonomous multi-un…

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/'marathon' ] || [ -L ~/.agents/skills/'marathon' ]; then echo 'A skill folder named marathon already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/bjcoombs/ai-native-toolkit' "$d" && git -C "$d" checkout --quiet 'f31582e1c9fe75950a9e522649565b93e3072fe0' -- 'skills/marathon' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/marathon' ~/.agents/skills/'marathon' && 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/'marathon' ~/.claude/skills/'marathon' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
