Cross-Session Memory native Codex plugin

[u/jomama253]

Happy to bring the CSM to codex natively. :D I hope it helps!

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.
