AGY is an agentic coding environment built for pair programming, repository inspection, background task execution, and codebase edits.
- Terminal CLI (
agy) with multi-workspace support. - Specialized subagents for research, browser automation, and code writing.
- Skill and plugin architecture stored locally in
~/.gemini/antigravity-cli/skills/. - File inspection, command execution, and structured artifacts.
# Check version and active configuration
agy --version
# Launch interactive session inside any repository
cd /path/to/project
agyOpenCode provides an open-source terminal interface for autonomous AI programming, acting as a local agent in your git workspace.
- Terminal-first workflow without requiring heavy IDE plugins.
- Works directly with local git state, diffs, and project files.
- Supports switching backend LLM providers (Anthropic, OpenAI, local Ollama, Groq).
Codex pioneered large-scale code synthesis, powering tools like GitHub Copilot and successor frontier models (o1, o3-mini, GPT-4o) tuned for code reasoning.
- Automated refactoring and test generation.
- Schema translation and API client drafting.
- Shell script debugging and syntax translation across programming languages.
git-tulkun is an automated GitHub Action created by Pramuditha Nadun that generates a dynamic, looping pixel-art Tulkun whale for your GitHub profile README.
- Repository: github.com/PramudithaN/git-tulkun
- Live preview: pramudithan.github.io/git-tulkun
- Growth: The Tulkun grows from a calf to an armored adult based on your commit activity.
- Coloring: The color palette is drawn from the primary languages across your repositories.
- Workflow: Runs daily via GitHub Actions and commits output files to an orphan branch without polluting your main git log.
