Quickstart

Causal is experience memory for AI agents — it records what your agents tried, what happened, and why, then serves that experience into the next decision.

Install

One command, from the project you want your agent to remember.

npx causal init

What it wires up

The installer detects the harness you are in, signs you in, installs the Causal Agent Skills, registers the MCP server, and adds an always-on rule that recalls relevant experience before the agent acts and captures outcomes afterward.

Nothing about your setup changes. There is no MCP block to hand-edit and no API key to paste into a project file.

What you should see

MCP server registered · memory skill installed · always-on recall rule added

Claude Code, Cursor, Codex, OpenClaw, and Hermes each report their own three lines. Anything outside that list uses the TypeScript or Python SDK.
