v0.1.0 - Trace intent. Debug causality.

Causari v0.1.0 — initial public release

Intent-addressable code for AI agents.

This is the first public cut of Causari. It is functional, cross-platform,
and ready for early adopters who want to instrument their AI-agent workflows
with causal provenance.

Install

One line (Linux / macOS)

curl -sSf https://causari.dev/install.sh | sh

One line (Windows / PowerShell)

iwr -useb https://causari.dev/install.ps1 | iex

Both scripts verify the SHA256 of the downloaded binary against
SHA256SUMS.txt attached to this release.

Highlights

• Content-addressable event ledger with BLAKE3 hashing — every agent
  action becomes an immutable, queryable event.
• Bidirectional causal graph — re trace walks the upstream cone
  (intellectual ancestry of a line), re impact walks the downstream cone
  (blast radius of an event).
• 15+ CLI subcommands: init, record, log, show, revert,
  diff, why, watch, bisect, fork, trace, find, impact,
  lens, mcp.
• Built-in MCP server — Causari exposes causari_record,
  causari_recall, causari_why to Claude Desktop, Claude Code, Cursor,
  Cline and Windsurf.
• Cross-platform: Linux (x86_64, aarch64), macOS (Intel, Apple Silicon),
  Windows (x86_64).
• Licensed under BSL 1.1, converting to Apache 2.0 four years after the
  release of each version. Production use is allowed; reselling Causari as
  a hosted service is not.

Quick start

# install
curl -sSf https://causari.dev/install.sh | sh

# in any project
re init
re record -m "first action"
re log

Or run any of the four end-to-end demos:

./scripts/demo.sh         # full lifecycle
./scripts/demo-trace.sh   # upstream causal cone
./scripts/demo-bidir.sh   # downstream impact + lens + revert preview
./scripts/demo-mcp.sh     # MCP server end-to-end

What's next

• A causari.dev landing site — live now.
• More agent runtimes integrated with the MCP server.
• Signed releases (Sigstore).
• Homebrew / Scoop / nix taps.
