harness-sync

100 / 100 · Low risk

Fine to try.

By harnessprotocol/harness-kit (GitHub) · coding · 10 stars · scanned at commit 4094970

Use when user invokes /harness-sync or wants to sync AI tool configurations across any of the 8 supported targets (Claude Code, Cursor, GitHub Copilot, Codex, OpenCode, Windsurf, Gemini CLI, Junie). Inventories installed skills, instruction blocks, and MCP configs on all detected platforms, reports divergence, and lets the user push or pull changes. Push path reuses harness-compile logic. Pull path updates harness.yaml and recompiles. Never overwrites without explicit confirmation.

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/'harness-sync' ] || [ -L ~/.agents/skills/'harness-sync' ]; then echo 'A skill folder named harness-sync already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/harnessprotocol/harness-kit' "$d" && git -C "$d" checkout --quiet '4094970dee9a31be7b899126aca1cd4256f57ca8' -- 'plugins/harness-share/skills/harness-sync' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/harness-share/skills/harness-sync' ~/.agents/skills/'harness-sync' && 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/'harness-sync' ~/.claude/skills/'harness-sync' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
