The skill folder itself installs clean and both internal references resolve, but real dispatch is a no-op without the separate agent-mux CLI: `agent-mux --help` returned 'command not found' (exit 127) on this machine, exactly the failure mode its own Error Handling table anticipates — so out of the box it can only produce a plan, not actually run Codex/OpenCode workers.

What GSD Coordinator does
Project-manager-style playbook for splitting a multi-step coding task across Claude, Codex, Codex Spark, and OpenCode workers, verifying their output, and synthesizing a final result. Triggers when work spans multiple dependent steps, benefits from model diversity, or needs an independent-model audit pass; it requires the external agent-mux CLI to actually dispatch workers, and falls back to a planner-only mode when that CLI is unavailable.
How to install GSD Coordinator
git clone https://github.com/buildoak/fieldwork-skills
cd fieldwork-skills
mkdir -p ~/.claude/skills
cp -r skills/gsd-coordinator ~/.claude/skills/gsd-coordinator
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.

Frequently asked questions
- Is the GSD Coordinator skill free?
- Yes. The skill itself is free from buildoak/fieldwork-skills. SkillProof publishes the install command and an independent test verdict at no cost.
- Does GSD Coordinator work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 15, 2026. Verdict: Works with setup. The skill folder itself installs clean and both internal references resolve, but real dispatch is a no-op without the separate agent-mux CLI: `agent-mux --help` returned 'command not found' (exit 127) on this machine, exactly the failure mode its own Error Handling table anticipates — so out of the box it can only produce a plan, not actually run Codex/OpenCode workers.
- What is the GSD Coordinator SkillProof Score?
- 8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 5/5.
- How do I install GSD Coordinator?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use GSD Coordinator with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
