Cross-Session Memory native Codex plugin

Version: 1.1.0+codex.20260722014812
Platform: Windows x64
Runtime: Node.js 26 (ABI 147)

This is the complete native CSM runtime: all canonical tools, compatibility aliases, lifecycle hooks, onboarding, re-entry, living state, beliefs, self-model, AgentBook, checkpoints, context cache, goals, work ledger, compaction, telemetry, and handoff automation.

Install

Extract the ZIP, open PowerShell in this folder, and run:

.\install.cmd

The installer verifies every bundled file, copies this immutable version under %LOCALAPPDATA%\CrossSessionMemory\CodexPlugin, registers the local marketplace, and installs the plugin. It creates a fresh local SQLite configuration only when no CSM configuration exists.

After installation, fully restart Codex, open /hooks, review and trust the CSM hooks, and start a fresh task. Ask Codex to call csm_runtime_status to confirm the database connection.

Data and secrets

The archive contains no .env, credentials, database, memories, or developer-machine paths. The installer stores local configuration under %LOCALAPPDATA%\CrossSessionMemory\config and local SQLite data under %LOCALAPPDATA%\CrossSessionMemory\data.

To use PostgreSQL or OpenAI embeddings, edit the installed .env using csm.env.example as the reference. Never send your populated .env with the plugin.

Integrity

MANIFEST.sha256 covers every file inside the extracted bundle. The adjacent release SHA256SUMS.txt covers the ZIP itself. The installer refuses modified or incomplete bundles.
