What this skill does
📦 Antigravity Skills Manager (rmyndharis/antigravity-skills) The antigravity-skills-manager skill empowers Google Antigravity agents and users to discover, search, install, and manage over 300+ agent skills from the open-source repository rmyndharis/antigravity-skills. --- Use this skill when Searching or exploring available agent skills in the antigravity-skills catalog. Installing a new skill into the global Antigravity configuration directory (~/.gemini/antigravity/skills/<skillid>/). Listing locally installed skills to check system capabilities. Managing skill updates or auditing active agent tools. Do not use this skill when Performing general domain coding tasks that do not involve discovering or managing skills. Working on tasks outside the scope of Antigravity skill management. --- Instructions Prefer the /skills-manager (or /skills) slash commands. They work wherever the plugin is registered and need no path resolution. skillscli.py does not sit next to this file. Installing this skill copies only SKILL.md into the skills directory; the script lives at the root of the checkout or npm package it came from — agy plugin install clones the repo, so it is at the clone root, and the npm package puts it at nodemodules/@rmyndharis/antigravity-skills/skillscli.py. Locate it before invoking it, and run it from there; python3 skillscli.py <cmd> from this skill's own directory will not find it. If neither the repo nor the npm package is on disk, use npx @rmyndharis/antigravity-skills (the ag-skills CLI) instead — it covers the same four operations. Ensure skill installations save to ~/.gemini/antigravity/skills/<skillid>/SKILL.md, or to AGSKILLSDIR when that is set. All underlying commands must use standard Python library features (urllib.request, json, os, sys) without third-party dependencies. --- Safety install writes instructions that every future Antigravity session loads automatically. …
