+### AI Agent Integration
+
+Two interfaces for AI agents — pick based on context cost needs:
+
+```bash
+# CLI (subprocess, zero context cost — output stays out of LLM context)
+stegg-cli encode -i carrier.png -t "secret" -o stegged.png
+stegg-cli decode -i stegged.png
+stegg-cli analyze suspect.png --full
+
+# MCP server (stdio transport — results go into agent context)
+stegg-mcp  # or: uv run --extra mcp python3 mcp_server.py
+```
+
+See `skills/stegg-cli/` and `skills/stegg-stego/` for harness-agnostic agent skills, and `AGENTS.md` for the quick-reference guide.
