How do I install the Skill Porter skill?

Run npx skillmds@latest add pranav-nexus/skill-porter in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Skill Porter safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Skill Porter?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Skill Porter free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Skill Porter

Imports, converts, and optimizes external agent skills (written for Claude Code, Cursor, or generic LLMs) into native Google Antigravity plugins and skills. Translates legacy tool references, adapts subagents to Antigravity's parallel invoke_subagent arrays, and bundles plugin manifests. Use when the user asks to "import skill", "convert skill", "port skill", "optimize skill for antigravity", or provides a GitHub URL to a Claude Code skill.

Antigravity Skill Porter & Optimizer

The Skill Porter autonomously bridges external agent ecosystems (Claude Code, Cursor, generic LLM agents) into native Google Antigravity (AGY) skills and plugins.

While platforms like Claude Code and Antigravity share the basic directory/SKILL.md layout, external skills typically contain hardcoded legacy tool names, single-agent sequential assumptions, and Claude-specific files. The Skill Porter translates these affordances and optimizes skills to leverage Antigravity's multi-agent runtime.

Core Capabilities

Direct GitHub Ingestion:
- Ingests public GitHub repositories (e.g. https://github.com/owner/repo) or local directories.
- Automatically discovers SKILL.md and preserves auxiliary files (references/, scripts/, examples/).
Deterministic Tool & Convention Mapping:
- Context files: CLAUDE.md / claude.md $\rightarrow$ GEMINI.md, AGENTS.md, .agents/rules/.
- Command line: Bash $\rightarrow$ run_command.
- File inspection: Read $\rightarrow$ view_file.
- File search: Glob $\rightarrow$ find_by_name, Grep $\rightarrow$ grep_search.
- File editing: StrReplaceEditor / Edit $\rightarrow$ replace_file_content.
- Artifacts: File dumping $\rightarrow$ Antigravity markdown artifacts (write_to_file).
Multi-Agent & Subagent Up-Leveling:
- Detects subagent workflows and injects Antigravity's parallel invoke_subagent batch arrays with Reactive Wakeup mechanics.
Automated Plugin Packaging:
- Generates plugin.json manifests so imported skills can be turned on/off in the Antigravity settings UI.
- Dual-installs to both ~/.gemini/config/plugins/<name>/ and ~/.gemini/config/skills/<name>/.
Diff & Verification (Dry-Run):
- Evaluates changes and outputs an interactive unified diff before applying.

Usage Instructions for the Agent

When the user asks to import or convert a skill from a URL or directory:

Step 1: Preview with Dry Run

Execute the porter script with --dry-run:

python scripts/port_skill.py <url-or-path> --dry-run

Review the diff to ensure domain logic is preserved while tool references and scaffolding are properly upgraded.

Step 2: Install the Skill

Run the command without --dry-run:

python scripts/port_skill.py <url-or-path>

To install into the current project workspace instead of globally, append --workspace.

Step 3: Validate Installation

Verify the generated files:

Manifest: ~/.gemini/config/plugins/<name>/plugin.json
Instructions: ~/.gemini/config/plugins/<name>/skills/<name>/SKILL.md Inform the user that the skill is ready to be invoked immediately.
