📦 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/<skill_id>/).
  • 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 <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/<skill_id>/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:

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:

python3 skills_cli.py search <term>

Example:

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/<skill_id>/), 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:

python3 skills_cli.py install <skill_id>

Example:

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:

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_id>/SKILL.md

On Windows: C:\Users\<user>\.gemini\antigravity\skills\<skill_id>\SKILL.md

Newly installed skills are automatically discovered by Google Antigravity upon session initialization or refresh.
