Integrations

agent-message works with any AI agent that can run a shell command. Three calls cover the protocol:

echo "body" | ~/.agent-message-cmd send <recipient>
~/.agent-message-cmd inbox
echo "reply" | ~/.agent-message-cmd reply

Global integrations

One install covers every repo on the machine.

Tool	Flag	Writes
Claude Code	(default)	~/.claude/commands/message-{send,inbox,reply}.md
Cursor	--integrate=cursor	~/.cursor/rules/agent-message.mdc
GitHub Copilot CLI	--integrate=copilot-cli	~/.copilot/copilot-instructions.md
Google Antigravity	--integrate=antigravity	~/.gemini/AGENTS.md
OpenAI Codex CLI	--integrate=codex	~/.codex/AGENTS.md

Per-repo integrations

Run from inside each repo where you want them.

Tool	Flag	Writes
GitHub Copilot Chat	--integrate=copilot	.github/copilot-instructions.md
Antigravity (per-repo)	--integrate=antigravity-repo	./AGENTS.md (cross-tool, opt-in)
Zed	--integrate=zed	./.rules

Doc-only

Configure by hand — these tools have no marker-block target we'd own.

Tool	Why
opencode	pre-1.0 config in flux
Continue.dev	JSON config patch by hand
Aider	use /run

Auto-integrate everything

./install.sh --integrate=all       # cursor + copilot + copilot-cli + antigravity + codex + zed
./install.sh --integrate=auto      # detect and integrate available tools
./install.sh --integrate=cursor,antigravity   # explicit list

--integrate=all does NOT include antigravity-repo (opt-in only — global covers it).

Uninstall:

./install.sh --integrate=cursor --uninstall            # global
./install.sh --integrate=antigravity --uninstall       # global
./install.sh --integrate=zed --uninstall               # per-repo (run from inside the repo)

Cross-agent interop

All integrations point at the same $AGENT_MESSAGE_DIR. A Claude session in ~/dev/repo-a and a Cursor session in ~/dev/repo-b exchange messages through the shared store — no central server, no MCP, no auth. Each agent picks its alias from .agent-message file or basename $(pwd).
