Tool compatibility

AmbyKit’s author-once, emit-per-tool design means one neutral source becomes each assistant’s native format. These are the selectable targets and their command surface. Several targets share one emitter (VS Code extensions, sibling CLIs).

Selectable targets

Target id	Assistant	Command surface
claude	Claude Code (CLI)	commands
claude-vscode	Claude Code (VS Code)	commands (alias of claude)
copilot	GitHub Copilot (VS Code)	commands
copilot-cli	GitHub Copilot CLI	skills
opencode	OpenCode	commands
cursor	Cursor	commands
cursor-cli	Cursor CLI	none (rules-only)
antigravity	Antigravity (IDE)	workflows
antigravity-cli	Antigravity CLI	workflows (reuses Antigravity)
codex	Codex CLI	skills

Where files land

Concern	Claude Code	OpenCode	Copilot (VS Code)	Copilot CLI	Cursor	Cursor CLI	Antigravity	Codex CLI
Rules file	CLAUDE.md (+@AGENTS.md bridge)	AGENTS.md	.github/copilot-instructions.md + AGENTS.md	same as Copilot	.cursor/rules/*.mdc + AGENTS.md	Cursor config + AGENTS.md	AGENTS.md + .agents/rules/*.md	AGENTS.md
Commands	.claude/commands/amby/*.md	.opencode/commands/*.md	.github/prompts/*.prompt.md	skills	.cursor/commands/*.md	none	.agents/workflows/*.md	skills — .agents/skills/*/SKILL.md
MCP file	.mcp.json	opencode.json → mcp	.vscode/mcp.json (servers)	~/.copilot/mcp-config.json (mcpServers, user)	.cursor/mcp.json (mcpServers)	reads .cursor/mcp.json	mcp_config.json (mcpServers, user)	.codex/config.toml — not written (out of scope)

Note

Claude Code does not read AGENTS.md natively — AmbyKit emits a CLAUDE.md whose first line is @AGENTS.md so there is a single shared rules source. User-level MCP files (Copilot CLI, Antigravity) are written only with explicit consent. Codex’s skills have no argument-placeholder convention, so AmbyKit rewrites $ARGUMENTS into instruction prose instead of leaving a literal token.
