# Antigravity Skills Manager > Global skills manager for Google Antigravity. Explore, search, install, and manage 300+ agent skills from the rmyndharis/antigravity-skills catalog using pure stdlib CLI tools. - Skill: `rmyndharis/antigravity-skills-manager` (Agent Skill) - Install (CLI): `npx skillmds add rmyndharis/antigravity-skills-manager` - Raw SKILL.md: https://api.skillmd.com/api/skills/rmyndharis/antigravity-skills-manager/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: rmyndharis (https://skillmd.com/u/rmyndharis) - Updated: 2026-09-09 - Page: https://skillmd.com/skills/rmyndharis/antigravity-skills-manager --- # 📦 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`](https://github.com/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//`). - 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. - **`skills_cli.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 `node_modules/@rmyndharis/antigravity-skills/skills_cli.py`. Locate it before invoking it, and run it from there; `python3 skills_cli.py ` 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//SKILL.md`, or to `AG_SKILLS_DIR` 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. Confirm the skill id with the user before installing, and show them what `search` returned rather than picking on their behalf. - `install` replaces an existing installation of the same skill id, discarding local edits under that directory. Say so before overwriting. - Never install a skill id the user did not ask for, and never install one that is absent from the catalog. - `install` writes under the resolved skills directory — `AG_SKILLS_DIR` when set, otherwise `~/.gemini/antigravity/skills`. Report the exact path back to the user rather than assuming the default. --- ## Purpose Provide a unified, lightweight, pure standard-library interface for managing Google Antigravity agent skills across platforms (Windows, macOS, Linux). --- ## Available Commands & Usage ### 1. List Catalog Skills Lists catalog skills with their categories and descriptions. An unfiltered listing is capped at the first 40 entries with a count of the remainder; add a filter to see a complete result set: ```bash python3 skills_cli.py list ``` *Slash command equivalent*: `/skills-manager list` (or `/skills list`) ### 2. Search Catalog Skills Filters skills by matching keywords in skill id, name, description, category, tags, or triggers. Multi-word queries match skills containing every term, in any order, and results are never truncated: ```bash python3 skills_cli.py search ``` *Example*: ```bash python3 skills_cli.py search flutter ``` *Slash command equivalent*: `/skills-manager search flutter` (or `/skills search flutter`) ### 3. Install Skill Installs the whole skill folder into the global skills directory (`~/.gemini/antigravity/skills//`), copying from the catalog shipped beside the script when present and downloading from GitHub otherwise. Any existing installation of the same id is replaced. Exits non-zero if some files could not be retrieved: ```bash python3 skills_cli.py install ``` *Example*: ```bash python3 skills_cli.py install flutter-expert ``` *Slash command equivalent*: `/skills-manager install flutter-expert` (or `/skills install flutter-expert`) ### 4. List Installed Skills Inspects local `~/.gemini/antigravity/skills/` directory and lists installed skills: ```bash python3 skills_cli.py installed ``` *Slash command equivalent*: `/skills-manager installed` (or `/skills installed`) --- ## Local Installation Storage Path Skill files installed via this skill are placed in: `~/.gemini/antigravity/skills//SKILL.md` On Windows: `C:\Users\\.gemini\antigravity\skills\\SKILL.md` Newly installed skills are automatically discovered by Google Antigravity upon session initialization or refresh.
