Documentation

Full README

@ghostpaw/codex

Agent memory as beliefs with a source, a certainty and a revision history.

bash

ghostpaw-codex --help

Local, evidence-backed memory for agents. One SQLite file, zero runtime dependencies.

Codex stores what an agent believes as claims with a source, a certainty, evidence counts, decay and an honest revision history. Agents search before they remember, confirm or correct instead of appending, and see which beliefs are stale, fading or weakly evidenced. It runs as a TypeScript library, an MCP server, a CLI and an Agent Skill, all generated from the same seven tools.

Website: codex.ghostpaw.dev

The release binary includes its runtime. npm and library use require Node.js 24+.

Install

Release binary (default)

Each line downloads the latest release asset, checks it against the release's SHA256SUMS and installs ghostpaw-codex into ~/.local/bin. On Linux and macOS the trailing export puts that folder on PATH for the current shell only: neither the line nor install.sh edits ~/.profile or any other shell startup file. The Windows script adds its folder to the user PATH (open a new terminal afterwards).

linux-x64:

curl -fsSL https://raw.githubusercontent.com/GhostPawJS/codex/main/install.sh | sh -s -- --target linux-x64 && export PATH="$HOME/.local/bin:$PATH"

linux-arm64:

curl -fsSL https://raw.githubusercontent.com/GhostPawJS/codex/main/install.sh | sh -s -- --target linux-arm64 && export PATH="$HOME/.local/bin:$PATH"
